Aberdeen Investment

What we’re doing

We’re carrying out on a major £5.3 million initiative to improve drinking water quality for around 20,000 homes in Aberdeen. The project involves upgrading around 100 miles of water pipes across the southside of Aberdeen and outlying areas.

What it involves

We’re relining and cleaning pipes to improve the quality of water flowing through pipes to customers' taps. It’s a cost efficient method of refurbishing pipes which still have a long life in them.
Some of the work will involve excavations to access water mains and some local traffic management will be put in place as required. We will do all we can to keep this to a minimum with local access being maintained where possible.
In the event of any localised disruption while the work takes place, Scottish Water will write to customers in advance. 

Where we're working

The first part of the project, in the Torry area, has been completed. In September 2013 we’re starting work in the Norfolk Road and Queen’s Cross areas. When complete work will start in a number of other areas including Mannofield, Culter, Berryden, Rosemount, Whitehall, Cove North, Findon, Portlethen, Newtonhill and Muchalls.

Scottish Water investing in Ardersier


For around 40 years, Scottish Water has operated a waste water treatment works at a site outside Ardersier. This essential facility is used to treat waste water collected from the village, as well as from homes and the businesses in the wider area - including Inverness Airport and a number of small settlements including Tornagrain and Fort George. Once the waste water has been treated at thworks, it is safely returned to the environment via an outfall pipe to the Moray Firth.

Scottish Water is delivering improvements to our essential waste water infrastructure in the area. The purpose of these works is to meet the needs of housing and economic growth in the area – including Tornagrain, Inverness Airport and Castle Stuart - while protecting and enhance the environment of the Moray Firth. 

We are doing this through:

  • An expansion of the existing waste water treatment works within Scottish Water’s land to enable the facility to process an increased volume of waste water as a result of these growth projects.

  • Installing a new underground pipeline to transfer waste water from these developments to Ardersier Waste Water Treatment Works.

  • Installing ultra violet treatment equipment within the existing site - this will improve the disinfection of the waste water which comes into the facility. While the Ardersier waste water treatment works has served the area well for many years, we are required by our environmental regulator, Scottish Environment Protection Agency (SEPA), to improve the quality of the treated water which is safely returned to the environment. The main reason for doing this is to protect the bottlenose dolphins and help improve the quality of the water in the Moray Firth.

  • Extending the existing outfall pipe, near Fort George, by 300 metres - this will take the discharge of treated waste water further out to sea and into deeper water.

The below map shows the route of existing and new pipes in the area:

Pipeline Project Update - 11th of January

Work will be taking place over the coming weeks to complete the remaining short sections of pipeline along the coastal path. The map below indicates the approximate area where pipeline installation is taking place this week; and the final area where it is expected to take place next week.

Sign-posted diversions will be in place for users of the coastal path while work is taking place.  Access to the slipway will be restricted in the interests of safety, but it can be opened upon request when appropriate. 


Scottish Water would like to apologise for the length of time that the coastal path has been disrupted by this work.  Our contractor is working hard to complete the remaining work as quickly as possible and will then carry out reinstatement of the affected areas.

C1005 road closure arrangements

Following engagement about the operation of the Traffic Management Plan which is in place for the Waste Water Treatment Works site, it has been agreed with Highland Council that the road closure on the C1005 will remain in place during periods Scottish Water is using the route for construction traffic, but that the road will be open outside these times.  Normally, when the road is open, the road closure signs and barriers will be placed to the side of the road; however, for longer periods when the road is not expected to be in use for HGV construction traffic, the signage may be removed. 

When the road closure is not operating, the 30mph speed limit and signage remains in force for all traffic using the route.  Should Scottish Water's contractor need to bring in a vehicle via the C1005 at any time, the barriers and road closure would be put in place to allow this to happen.

During October and November, we anticipate that a small number of HGV deliveries will be required. These deliveries will be made using the C1005 via the arrangements outlined above.

Engagement with customers

We are pleased to have had the opportunity to meet many of our customers in Ardersier at information events and meetings in recent months. The feedback given to us has been invaluable in helping to prepare for the work to be carried out and understand ways in which we can minimise the impact on our customers.

Argyll and Bute Environmental Improvements

Coast view


Scottish Water is investing over £5m in Argyll and Bute to improve and protect the coastal waters around the Holy Loch and parts of the Firth of Clyde.

The improvement works are at five different sites at Toward, Rhu, Kilmun, Innellan and Strone.

The improvement works will ensure waste water collected from local homes and businesses that are connected to the existing sewer network is treated, preventing the discharge of untreated water into coastal waters. This will enable compliance with strict water quality standards while protecting and enhancing the environment.

We held 3 public information events in Rhu, Kilmun and Innellan from 28th February to 2nd March. At these events we had the drawings on display and had the project team to answer any questions the community had. We have now taken these on board which helped form our design and management of the traffic flows. 

The table below shows the progress in each village: -

Project Overview Map

Badenoch and Strathspey supply enhancements

River Spey near Aviemore

Scottish Water supplies high-quality drinking water to more than 10,000 properties in the Badenoch and Strathspey area.

We recognise that, following the opening of a new water treatment works in 2012, some customers found that the water was not to their taste.

Since Spring 2016 we have taken a number of steps to improve the supply in the local area including improvements to the performance of the treatment works and cleaning water pipes.  In April 2017, we completed the introduction of chloramination - a treatment process which allows for a reduction in the level of chlorine, helping to further improve the taste of drinking water.

In response to concerns that were raised by customers about public health issues, NHS Highland carried out and has published a review of available local health data in Badenoch and Strathspey.

The report prepared by NHS Highland’s Consultant in Public Health Medicine, Dr Ken Oates, concludes that, “From the evidence seen, reviewed and discussed there is no scientific data which suggests that the water supply to Aviemore and the surrounding area is in any way unsafe to drink, or to bathe in.  Indeed the opposite is true – that the water is of a high quality and over the past 5 years has consistently met the strict standards laid down for the water industry in the UK and Scotland.”

Responding to the report’s publication, Scottish Water’s Chief Operating Officer Peter Farrer said:

“Following discussions with our customers in Badenoch and Strathspey earlier this year, I gave a commitment to meet NHS Highland to raise the concerns that had been expressed about public health issues.  The report now published is the key outcome of that meeting and I am grateful to Dr Oates for his care in producing it.

“Scottish Water recognises that the change in the water supply for Aviemore and the surrounding area which took place in 2012 was not a positive experience for many of our customers.  For a short period, the high level of chlorine which had been required to treat the water previously sourced from Loch Einich was continued and this resulted in an unacceptable taste and smell of chlorine at customers’ taps.  Although the water from the River Spey boreholes at Kinakyle is of very high quality, its characteristics are different and we did not explain this well enough or respond to customer feedback quickly enough at the time.

“We have since worked very hard to listen to the views of our customers and to deliver improvements in response.  The successful introduction of chloramination in early April marked the culmination of this work, dramatically reducing the remaining level of ‘free chlorine’ reaching our customers and directly addressing the key issues about taste and odour which most customers had raised with us.

“Dr Oates’ report addresses the remaining public health issues that had been raised and I would encourage anyone with concerns to read it.  I would like to thank our customers for their patience while we have made these improvements .   We are committed to continuing to provide a first class service to local communities.   I hope the action we have taken together with the statement from NHS Highland provides reassurance about the high quality of the drinking water provided in Badenoch and Strathspey.  Of course, we ask anyone experiencing issues with their water in future to contact us so our local team can investigate and take any action required.”

Investing in Edinburgh

We're transforming Edinburgh’s water and waste water systems with a multi-million pound programme of investment.

We’re taking care of your water supply by upgrading many miles of water mains network, to improve security of supply and provide clearer, fresher drinking water. We're also upgrading Edinburgh’s sewer 
network to improve the environment while reducing the risk of flooding.

Investing in Inverurie

Watch our October update video here.

We are investing £21M upgrading the existing wastewater treatment works (WwTW) to ensure it complies with current EU directives to improve the water quality around River Don and Urie and to provide better capacity for the future.


The new works will be built within Scottish Water land where the existing works are. We are using state of the art technology which means the new works will have a smaller carbon footprint and will be more efficient.

It will use an innovative process called ‘Nereda’, which is a new method of wastewater treatment, pioneered by several wastewater companies in the Netherlands.

This method has many benefits which include:

  • Compact and uncomplicated designs

  • Lower construction costs

  • Lower operation and maintenance costs

  • Treats wastewater to higher standard with no or minimal chemicals and related wastes

  • Significantly lower energy consumption

  • Reduction in odour

  • As little as a quarter of the land required

For more information on how the Nereda process works watch this video here:

Watch our video here of Keith Robertson describing the Nereda process being put in place at Inverurie WWTW.

3D model design

The image above shows the overall layout of the proposed Nereda tank and screens

Watch our video here of James Bex describing the 3D scanning process.

The project is due to start on the 4th September 2017 and is expected to take around 18 month to complete.

The work should have minimal impact on the community as most of the construction will be within the existing WwTW sites.

For the duration of the works there will be a temporary 20mph speed restriction on the B993 between the entrances to the current treatment works. This is to help ensure the safety of staff and site workers during the works.  Additional safety measures will include height restriction signs/barriers being installed either side of the rail bridge to ensure the safe access for construction traffic under the bridge 

There will also be a temporary road closure required on the B993 as shown below.  This four week closure is to allow us to lay pipework on the road under the railway bridge. The date for the closure has yet to be confirmed and local communications will be issued once a date is confirmed.  A signed diversion route will be in place during this section of the work.


The project is being delivered by our alliance partners ESD, a joint venture between Galliford Try, MWH Treatment and Black and Veatch.


Loch Ness Water Project

Investing in the future of your water supply in Fort Augustus and Glenmoriston

Working with its delivery alliance partner, Efficient Service Delivery (ESD), Scottish Water has developed proposals to replace the two existing water treatment works which currently serve the area with a single new works which would be located in forestry south of Invermoriston. 

The proposals include:

  • Building a new water treatment works in forestry south of Invermoriston, drawing water from Loch Ness

  • Installing a new water main to connect the two communities

  • Building a new storage tank on high ground to the north of Fort Augustus

  • Creating water storage capacity at Scottish Water’s existing site in Invermoriston

The scheme as a whole would provide an improved water supply for both communities, with greater resilience and capacity to support future growth. 

It would also include the renewal of key sections of Scottish Water’s network in Fort Augustus, including a new twin pipe main crossing beneath the Caledonian Canal and the River Oich.

Information event

 An information event will take place at the Lovat Hotel in Fort Augustus on Thursday 15 March from 3pm until 8pm. Residents and businesses with an interest in the plans are warmly invited to drop in and discuss any questions, comments or concerns with members of Scottish Water’s project team.



Scottish Water is investing in Rutherglen to upgrade the sewage system and mitigate against flooding in the local area.

Site investigation works were carried out during 2016 in preparation for the two phases of Sewer Network improvements due to take place this year, commencing in late September 2017 with an expected completion date of late July 2018.

Water diversion works required to facilitate the upgrade to the local waste water system will commence from Monday 25th September and will last approximately 4 weeks. Temporary 4 way traffic lights will be in operation during this time and will be manually operated during peak times to ensure minimal disruption to local road users.

Once diversion works are completed, sewage upgrades to Viewpark Drive will begin week commencing 06 November 2017. This work will involve road excavations carried out in 50 metre sections beginning at the Stonelaw Road end and heading west towards Victoria Road, crossing Victoria Road and continuing. Full pedestrian access will be available at all times however vehicular access will be restricted to residents (with the exception of emergency vehicles). This will not affect waste bin collection as onsite personnel will ensure waste is collected.

The second phase of the project includes the construction of a water storage tank adjacent to the west of the site compound currently being established in Stonelaw Park. The tank will be submerged underground and will provide extra storm water storage to significantly reduce the risk of flooding. The installation of the underground storm tanks will proceed simultaneously with the sewer pipe installation along Viewpark Drive and access to the park shall remain available out with the enclosed area of work.

Once this work has been completed, a third phase of works in Buchanan Drive will follow between summer and Christmas 2018. We will provide further information on this third phase of works during springtime next year.

Strathpeffer sewer renewal

Scottish Water, with its alliance partner amey-Black and Veatch (aBV), is carrying out essential work to renew the main sewer in Strathpeffer on the A834 from the junction with Ulladale Crescent (near the Community Centre) down to the entrance to the Ben Wyvis Hotel.  The work is needed to ensure the sewer can continue to serve our customers and protect the local environment in the years ahead.

To complete the first phase of work, it was necessary to close the A834. The road has now re-opened to traffic, but we would like to apologise for the need to extend the closure beyond its intended three weeks duration.

Repair works will now continue until the end of April 2018. Three-way traffic lights will be required on the A834 near the primary school for around four weeks. Two-way traffic lights on the A834 will then be used on sections of the road until the remaining work is complete.

Strathpeffer sewer works map

A specialised re-lining technique will be used for much of the work to avoid the need for widespread excavation in the village centre and reduce disruption in the community.  

Pedestrian and vehicle access will be maintained as far as possible throughout the rest of the work and local businesses will be open as usual.

View a video of the work here 

Information event

An information event was held on Wednesday 29th November at Strathpeffer Community Centre to allow customers to discuss our plans with members of our team and provide feedback.  We would like to thank everyone who came along to find out more and share their views, which have contributed to preparations for the planned work.

The information that was available at the event is available to download below.

Ayrshire and East Renfrewshire Water Mains Improvement

 Ayrshire Pipeline

The £120m investment will connect the water main system in much of Ayrshire with the Greater Glasgow area’s water network and will benefit more than 200,000 customers in Ayrshire and East Renfrewshire by providing increased security of supply. This will allow us to respond more effectively to operational issues such as burst water mains and minimise disruption to our customers.

Bradan map

First Phase of water mains investment

The first phase of the project began in May 2016, comprising of the installation of 13 miles of new water main from near Newton Mearns to the Fenwick/Waterside area. This first phase is now nearing completion and whilst most of the 13 mile route is rural and through private land, construction teams have worked hard to overcome challenges such as working on peaty bogland and installing a section of the water main under a railway line near Barrhead. 

Our alliance partners, amey Black and Veatch (aBV), have also constructed a new pumping station at our existing water treatment works near Darnley as part of the project.

Second Phase

With the first phase now moving towards completion, Scottish Water has now started phase two of the Ayrshire and East Renfrewshire Water Mains Improvement in June 2017. The key elements of this stage of the project are as follows:

  • Construction of another stretch of water main approximately 13 miles long, installed from Amlaird Water Treatment Works in Waterside to Highlees Pumping Station near Dundonald
  • Construction of a new pumping station near the Grassyard interchange at Ralstonhill, east of Kilmarnock. Like the first phase of the project, the second will include stretches where the pipe goes under a railway line, near Crookedholm, and under a number of roads with road traffic management required. This second phase is being carried out on Scottish Water’s behalf by our alliance partners Caledonia Water Alliance.

Ayr Water Mains

Work started in Ayr town centre on 24th April 2017 to replace the water mains to ensure our customers continue to receive the highest quality drinking water possible.

Key Project Facts

  • The overall project will take around 8 months to complete
  • On rolling programme, work is currently being carried out on High Street which is expected to last until mid-July.
  • A road closure will be in place n High Street between the hours of 8pm and 6am to minimise disruption.
  • We will notify all affected customers prior to any water supply interruptions
  • There will be road and lane closures in the town centre and we will be updating this page on a regular basis, so please keep checking back for up to date information.
  • The work is being carried out by our alliance partners Caledonia Water Alliance (CWA) on our behalf.
  • Please note that all dates are approximate and are subject to change.

A public information event was held on Tuesday 11th April at Ayr Town Hall to give the community an opportunity to meet the project team and ask any questions about the project.

Update September 2017:

As of mid-September our Alliance Partner, Caledonia Water Alliance (CWA) have completed work in 44 of the 60 sections of the Ayr Water Mains network requiring renewal.The project team have faced many challenges along the way but our main priority has remained the customer and trying to minimise disruption where possible.

CWA’s Customer Liaison Officers believe that going the extra mile is a key part of their job and have consistently worked to achieve our main priority, helping customers in various different ways including taking bins out, helping the elderly with shopping, assisting with the removal of heavy household appliances and delivering bottled water to vulnerable people.

We have worked in collaboration with Ayrshire Council along with local community groups, accommodating planned public events and where necessary changing our programme of works. We’ve also adapted working hours to suit local businesses in an effort to minimise disruption to trading.

Seeking opportunities to leave a positive legacy and give back to the community has also been a key priority. CWA have visited local schools throughout the duration of the project, highlighting health and safety in a fun way for the children and providing prizes for those who took part. They recently donated merchandise including re-usable water bottles and school supplies to be used at Ayr Fun Day and set up a safe parking area for the community games event in Dundonald.

Ayr fun day

The project is due to be fully completed by the end of this year and we would like to thank local customers for their patience and understanding whilst these essential works are carried out. We will continue to work hard to put the customer at the heart of everything we do, keeping disruption to a minimum and going the extra mile for our customers. 

Ayrshire and East Renfrewshire Chloramination

Taking care of your water supply

If you have received a postcard to your home or business from Scottish Water it will be to let you know we are investing to improve your water supply. 

As part of this, we will be changing the way we treat the water supplied to your property and we will be using a different process called chloramination.

This process is used in the treatment of water supplied to more than one million people in much of Edinburgh, Aberdeen, Inverness and other parts of the Highlands.

As part of our long-term investment programme to improve water quality to our customers, we are gradually increasing the number of areas in Scotland supplied with chloraminated water.

Bilston Water Mains


On-going work to upgrade aging water pipes in Bilston will see the introduction of temporary traffic lights at a junction of the A701 (Seafield Road).

From Sunday 11 February the lights will be in use at the junction with the A703 (Seafield Moor Road).

During this time the permanent lights at the junction will be out of use and the temporary lights will operate between 7am and 7pm.

Two temporary pedestrian crossings will operate in the area while the temporary lights are in use, for approximately four weeks. 

To date 3.5km of pipes have been laid as part of the £600,000 upgrade  which involves replacing or re-lining around 4km of old cast iron mains to make sure customers continue to receive clear, fresh water.

The work to reduce the risk of bursts and ensure our customers continue to receive highest quality water possible began at the start of November and is set to last up to six months.

We want to thank customers for their patience as this essential upgrade to the water network takes place.

Our Alliance Partner Caledonia Water Alliance (CWA) is carrying the work out and as the project progresses we will update this webpage and keep all affected customers up dated.

Dundee Water Mains Improvement


Project Overview

Scottish Water is investing £5m in upgrading Dundee’s water infrastructure. We are investing to ensure our customers continue to receive the highest quality drinking water possible. Water mains can vary in age and that’s why the upgrading, and in some cases replacement, of these essential supply pipes is vital to ensure we achieve maximum water quality and security of supply for our customers.

What does the work entail?
Pipe refurbishment work includes replacement, re-lining the internal surface of the mains or cleaning them by swabbing and flushing. This improves the water quality from the existing water mains pipes by cleaning any deposits that have built up over time.

Update January 2018

The next stage will see work begin on Monday 29 January, with a southbound lane closure in place on Old Glamis Road from the junction of Kelvin Street to the junction of Clepington Road.


The lane closure is expected to be in place for approximately three weeks.


Local access will be maintained throughout the work, though there may be some parking restrictions in place.


Scottish Water and CWA do all they can to minimise disruption during any project and this lane closure is required as excavations will be required for this part of the work.


All traffic management is agreed in advance with the local council.



Gairloch Waste Water Treatment Works Improvements

Scottish Water is planning an investment in its Gairloch Waste Water Treatment Works, which serves around 1,000 customers in Wester Ross.

Project Overview

The investment will improve the reliability and sustainability of the facility while continuing to protect the environment.

A new treatment works will use proven technology to achieve environmental discharge quality requirements, with a lower carbon footprint. There will be reduced vehicle movements to and from the site, reduced noise and less visual impact as a result of landscaping and the removal of some existing structures.

Following independent review, there will be a 25-metre extension to the existing outfall in Loch Gairloch which will take the pipe about 80 metres out from the shore. 

In 2016, Scottish Water put our original proposals on hold while the community’s applications for the Gairloch and Sand beaches to be designated as bathing waters were considered by the Scottish Environment Protection Agency (SEPA).  The Scottish Government confirmed its decision to grant bathing water status in December 2016.


Key information

  • The current Gairloch WWTW was completed in 2002.  The existing treatment process used at the works has proven unreliable to operate and maintain.  The majority of membranes within the works are up to eight years old and are reaching the end of their lifespan

  • Scottish Water will work with the Scottish Environment Protection Agency (SEPA), its environmental regulator, to ensure the discharge of treated waste water from the facility meets SEPA’s environmental standards. Following the Scottish Government’s decision to grant bathing water status to the Gairloch and Sand beaches, we have re-applied for an amendment to our discharge licence to demonstrate how the new bathing waters environmental standard will be met

  • As a result of the need to update the design to include filtration and ultra-violet treatment, we now anticipate that construction will not be able to begin earlier than winter 2017/18

  • In view of this delay to the delivery of a replacement works, we carried out maintenance work at our existing works in spring 2017 to minimise the risks associated with its operation during the 2017 bathing season

Licensing process


Scottish Water has now re-applied to SEPA for an amendment to our discharge licence at Gairloch, reflecting the decision to designate bathing waters at Gairloch and Sand beaches.

The license application was advertised in the Ross-shire Journal on Friday 25th August 2017 and full details can be found on SEPA’s website

Representations can be made until Tuesday 26th September via email to or by post to Registry Department, SEPA, Dingwall Office, Graesser House, Fodderty Way, Dingwall, IV15 9XB, quoting reference number CAR/L/1002928. 


Listening to our customers

Listening to our customers is important to us and in summer 2016 we held three information events and liaised with the community council about the work that was then proposed. Our proposals were then put on hold in response to the community's request while the applications which had been submitted for bathing water status were considered.


A further information event took place at Gairloch Community Hall on Monday 11th September 2017 from 3pm until 7pm, followed by a meeting with Gairloch Community Council.  Thank you to everyone who attended these sessions to find out more and discuss our proposals with our team.  

The presentation materials are available to download below with further details of our updated proposals.  Please don’t hesitate to contact us if you have any questions that our team can help with.

Hawick Sewer Improvement Project

All works are now complete.

Key Project Facts:

This £1.2m project at Duke Street, Hawick in Scottish Borders was to replace the damaged public sewer during the storms of December 2015. This will also help alleviate flooding during periods of heavy rain and storms.

The work involved replacing the damaged section of sewer which crosses the River Teviot at Mansfield Road and Duke Street / Glebe Mill Street in Hawick.  This will bring a number of important benefits to the community.

The work was completed in collaboration with Scottish Borders Council and was carried out by our contractors Morrison Construction. 

Inverclyde and Renfrewshire Mains Upgrade

Work to install about 12.5 miles of new water mains between Greenock Water Treatment Works (WTW) and customers in Kilmacolm and Lochwinnoch is about to start in Greenock on the 29th November 2016. The project is to improve water quality in these areas and is expected to be completed by late 2017. Most of the pipework will be laid through fields to reduce the impact to our customers.

The work will involve the following:

  • Installation of three miles of new water main from Whinhill Service Reservoir in Greenock to Dougliehill Service Reservoir
  • Construction of a new pumping station at Whinhill Service Reservoir to pump water from there to Dougliehill Service Reservoir and another at Burnbrae near Quarrier’s Village
  • Installation of three miles of water mains from Dougliehill reservoir to Kilmacolm, which will tie in to the existing water mains in the village

Update 30th January 2017:

Work to upgrade the water mains is starting on Kilmacolm Road on the 13th February 2017 for 4 months. We will be working jointly with Scottish Power, who are also laying power cables at the same time, to reduce the impact on the community.

From the 20th February there will be stop go signs on Dougliehill Road for approximately 1 week. This is to enable the installation of water pipes across Dougliehill Road.

Road Closure

A road closure on Auchmountain/Kilmacolm Road will take effect from 27th February for around 3 weeks and a lane closure for east bound traffic lights will be in place on Kilmacolm Road from Leven Road to Glenbrae Road. There will be temporary traffic lights and parking restriction in place at this time. Please follow all signs put in place.

 We will keep the community updated with information of the traffic management and affected customers will be notified in advance of any planned interruption to their water supply.

Isle of Seil


Scottish Water's objective is to create a positive impact on our customers and communities through our activities and investment programme. On the Isle of Seil we want to deliver a long term, sustainable Waste Water Treatment System for present and future generations.

To help us achieve this we have set up a community stakeholder group chaired by Michael Russell, the constituency MSP for the area. This group will ensure we are listening to the community whilst providing information about various options being investigated.

The group also includes Chris Chubb, an independent expert who is there to guide thinking and provide additional reassurance.

Proposals for the Waste Water Treatment on Seil

We held an information event on the 6th December 2017 at the Seil Island hall.The event was well attended with approx. 50 people in attendance. At the event we discussed our progress with studies and investigations and presented our preferred site location and associated access track which we will be taking forward to planning. 

As there had been significant change to the proposed access track we felt it was right to meet with the community to present the proposal and allow discussion before we progressed to the next phase. 

The main aspects of feedback received from those who attended in December centred on 3 main areas:-

    1. People who are supportive of the location and proposals

    2. People who were pleased that an alternative access track had been established following previous feedback about concerns.

    3. People who are completely against the site location due to its unspoiled nature location  

There was always an understanding from the outset that it would be very difficult to find a solution that would meet the unanimous approval of the community and this has proved to be the case. When the planning application goes live all individuals will have the right to make representations to the planning authority via this statutory process.  

Next steps

Planning submission is likely to be early 2018 for the Seaview septic tank and summer 2018 for the proposed new treatment works. We will write to the community council to confirm when these applications will be submitted and the final planning drawings will be able to be viewed on-line and in the village hall.

Roanhead Terrace Sewer Flooding

Work started in March 2017 on a sewer replacement project which will address flooding issues in the Roanhead Terrace area of Kincardine. 

Work was recently completed ahead of schedule by over two weeks


The project involved the replacement and re-lining of the existing sewer pipe along Toll Road. It was expected to take five weeks to complete but was actually completed in two and a half weeks

There were roadworks on Toll Road including a lane closure on Toll Road between Mercer Street and Dewer Avenue with temporary traffic lights in use. There was also access and parking restrictions. 

During the work the junctions of Mercer Street and Regent Street with Toll Road were closed. Local diversions in place.

The eastbound bus stop on Toll Road located near the junction with Regent Street was suspended and a temporary bus stop installed to the east of Dewer Avenue.

The project was delivered by our Alliance Partners amey Black & Veatch (aBV).

Mauricewood Road Roundabout

We are currently carrying out the work to divert the raw water mains pipe at Mauricewood Road in Penicuik. These essential water mains are used to supply Glencorse Water Treatment Works, which provides drinking water for most of Edinburgh and parts of Midlothian.

The purpose of this work, which is being done on behalf of the housing developer Taylor Wimpey, is to make way for the construction of a new roundabout at the junction of Mauricewood Road and the A702.

Work is continuing on the diversion of the raw water mains pipe at Mauricewood Road in Penicuik. Due to the engineering challenges we have faced and the complicated nature of this work it is proving to be taking longer than expected. Currently one pipeline is fully complete and installed and another two are ready and waiting to be installed in a deep trench.

Road Closure

The road closure at the junction of Bellwood Road and Biggar Road was lifted on Friday 14th July, 2 weeks earlier than expected.

Our delivery partners Farrans are working days from 5 to 6 and sometimes 7 days a week in order to minimise the overall duration.

The target date for completion is Autumn 2017.

Milnathort sewer flood prevention project

This £1.6m investment in Milnathort involves upgrading of the waste water network to help prevent sewer flooding.

This includes construction of underground waste water infrastructure which will involve new manhole covers and sewers.

We are regularly communicating with the Milnathort community regarding the work and any upcoming road closures. We are also regularly providing information via the Kinross Newsletter publication.

The first of the postcard notifications for the first road closure has been sent out to customers and we will issue similar postcards as the work progresses.

Moffat View Plains

Moffat View sewer repairs 

Following the collapse of the road in Moffat View in March 2016, Scottish Water in collaboration with North Lanarkshire Council, is investing £800k to repair and upgrade the damaged sewer pipes to prevent further flooding. The work involves the installation of two new manholes and a new section of sewer. While the work is on-going temporary over-pumping will be carried out but will be removed once the work is complete.

The project started in late September and has made good progress. All infrastructure is now in place, however, the sheet piling is still in place and reinstatement works are still required.

North Lanarkshire Council will be also working alongside us to mitigate the issues with ground water. They will be commencing with their works once we have completed ours. We would like to thank the community for their continued patience and cooperation while we carry out these essential works.


Moodiesburn Environmental Improvements

Site investigation works 

Work is due to start in Moodiesburn on some site investigation work ahead of a planned project to renew the overland sewer pipe that goes through The Glen area in Moodiesburn. This work will help prevent bursts and protect the local environment well into the future.

Update 27th February:

Work on the second phase of trial holes will start on 1st March 2017. This phase of work will involve the removal of trees and the temporary construction of an access track across the field form the A80 to the Strathkelvin Path. This is expected to take around 4 weeks to complete. Access will be maintained at all times but there will be a lane restriction on the A80 for the first week.

Construction of access road March 2017
Construction of access road: March 2017

Site investigations involve a series of trial holes to help determine ground conditions ahead of the main construction work which is due to take place late next year.

Work began on the 9th January 2017. Due to the more challenging access route to the site, these investigation works are being carried out in phases which will take place roughly over a period of 4 months.

There will be a temporary diversion and access restriction to the Strathkelvin Railway Path for a short duration during the work. Please follow all signs put in place. However, vehicle access for nearby residents in Bedlay Castle Estate will be maintained at all times.

We would like to thank the community for their patience and cooperation while we carry out these works.



Investing in Oban's Water Supply


We are investing over £29M in Oban’s water supply. This includes the construction of the new Tullich Water Treatment Works, which started in January 2016 and is expected to be complete in late Summer 2018 with further investment expected.

This investment will ensure that thousands of customers continue to enjoy clear, fresh drinking water that meets the most stringent quality standards and will also accommodate planned growth in Oban.


At present, work is on-going on the new Water Treatment Works where innovative 4D visualisation technology has been used by our Alliance Partners, ESD (Efficient Service Delivery) to help deliver the project. Effective tools which use new technology to enable offsite building have also been used, in turn removing the need for 8 weeks’ worth of temporary scaffolding and improving efficiency. In a bid to reduce our carbon footprint, 90% of excavated materials (such as stone etc.) have also been reused on site, saving the need to transport and dispose of these materials; this also avoided increased construction traffic through Oban.


An interesting fact about the project is that over 35000 metres of cabling is being installed in the plant- that’s enough cable to stretch from Oban to Loch Awe!


Other areas of investment are still in the planning stage but as the project progresses we will be engaging with the local community to explain what the planned works will mean for them and what impact they will have. This page will also be updated with information as the project progresses so please keep checking back for updates.

We visited Rockfield Primary School which is located just a few minutes from the site of the new Tullich water treatment work and talked to the children about the new works, the water cycle and the benefits of staying hydrated. Check out this video of one of the classes participating in the water network challenge game.

Trinity Sewer Upgrade

New banners displayed on site at Trinity

Work to replace the rising main along Trinity Road started in March 2017. The sewer pipe is deteriorating and needs to be replaced to reduce the risk of bursts and ensure it continue to operate and is fit for purpose into the future.

The work, which started 20th March 2017,  involves a road closure along Trinity Road and Primrose Bank Road. The work will be carried out in 3 main phases to reduce the impact on the community. The project is expected to take around 6 months in total to complete.

Update: 30 June:

Work on Phase 2 will soon be complete with reinstatement due to start very soon.

Phase 3

This phase is due to start on 7th July and is expected to take around 6 weeks to complete. The Primrose Bank Road junction with Trinity Road will be closed during this time. Local diversions will be in place with some parking restrictions. Trinity Road will be re-open to 2 way traffic.

Trinity Road phase 3

The final phase will involve completing the connection of the new rising main into the waste water pumping station. These works will be within the boundary of the existing Scottish Water compound and will utilise the grassed area opposite Lower Granton Road. This phase will take up to 8 weeks to complete.

The site compound will be situated on the grassed area on Lower Granton Road for the duration of the project. Unfortunately we are required to suspend parking at this section during this time. Apologies for the inconvenience this may cause.

Uphall Sewer Improvement Project

This £350,000 sewer improvement project invovles the renewal of 410m of cast iron rising main which runs from Uphall Pumping Station to a gravity system at MacFarlane Place in Uphall, West Lothian.

We've made up a Frequently Asked Questions document here for residents and road users.

Work began on Thursday 2nd June 2016 and was completed in October 2016.

We are currently carrying out the final phase of the project which consists of the replacement of the mains pipe along the footpath behind some properties on MacFarlane Place. All residents will be updated as to when these works will progress.

This work is being carried out by our alliance partners aBV.


West Lothian Water Mains Upgrade

Scottish Water is upgrading the water supply in West Lothian.  This £3.6 million investment will improve the water quality and reduce the risk of pipes bursting.

The project involves the rehabilitation of about 46 kilometers of water mains pipe in Armadale, Blackburn and Broxburn. Work began in Armadale in 2016 and has recently begun in Blackburn.

The work in Blackburn is expected to be completed by the end of August.

Pipe refurbishment work includes replacement, re-lining the internal surface of the mains or cleaning them by swabbing and flushing. This improves the water quality from the existing water mains pipes by cleaning any deposits that have built up over time.

We are currently working in the following streets:

  • Hopefeild Road
  • Hopefield Drive
  • Hopefield Place
  • Whitehill Drive
  • Whitehill View
  • Yule Place
  • Yule Terrace
  • Riddochhill Road
  • Ladeside Road

We will be updating this page as work progresses.

Our alliance partner, Caledonia Water Alliance (CWA) who are carrying out the work on our behalf, visited local school Blackburn Primary to give a presentation explaining about where their water came from and teaching the children how to be safe when there is construction going on around them.

Westray Water Treatment Works Upgrade

Scottish Water is set to improve the security of supply to Westray by upgrading the current works to provide the area with additional storage.
Works include the construction of a new clear water tank and associated pump kiosk within the boundaries of the existing water treatment works site. The tank will be 12 metres long x 6 meters wide x 6 meters high 

Construction is due to start on Tuesday 18 July 2017 and is expected to take around 10-12 months to complete. Please note that this start date is different from what was stated in initial postcard notices sent to customers.

We do not anticipate any planned disruption to your services and sinks and taps etc. can be used as normal. We will update this webpage as works progress.

While the Clatto Water Treatment Works remains an integral part of our water supply network to the City of Dundee, the depot and adjoining land is now surplus to our operational requirements.


Dalmuir Waste Water Treatment Works

Further improvements at Dalmuir Waste Water Treatment Works, Clydebank

Scottish Water in November 2013 started work on substantial improvements at the Dalmuir Waste Water Treatment Works (WWTW) in Clydebank.The £20m project, which received planning permission from West Dunbartonshire Council,  will enhance the operability and all round performance of the WwTW and reducing the potential for odour.

Scottish Water and Saur Services Glasgow Ltd (SSG), which operates the WWTW on behalf of Scottish Water, introduced a new treatment process there in 2010. This new process, called centrifuging, has been running successfully  using a temporary facility.

Centrifuges are like large spin-dryers which dry off water from liquid sludge to produce a sludge cake and ensure that the sludge is in a suitable state to go to land reclamation.

The temporary centrifuge system at Dalmuir WWTW has improved the sludge management process and we would now like to make this permanent. To do this, we need to erect a new building at the WWTW to fully enclose the equipment.

The investment  which we estimate will take about two years to complete, also includes a process which will improve the quality of waste water we discharge from the WWTW under licence from the Scottish Environment Protection Agency(SEPA) into the River Clyde.

It will involve the construction of housing for the system and a de-odourising unit along with other operational facilities.

Scottish Water is advising residents in the Dalmuir area of a possible temporary increase in traffic and noise levels at Dalmuir WWTW during our improvement work

As part of the project, piling work is due to begin around January 20, depending on weather conditions, and continue until the end of February.

During this work there might be an increase in traffic to and from the WWTW and noise levels. However, we will make every effort to minimise this, and the work is being carried out at a location on the site which is as far away from adjacent properties as is possible.

Scottish Water would like to thank customers in the area for their patience and understanding while we carry out this important work.
