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:

Weekly pipeline progress update for week commencing Monday 1st May

Stuart Street 

The map below shows the progress of work being carried out on Stuart Street, both what has already been completed and what is planned for this week. During week commencing 1st May, the junction between Manse Road and Stuart Street will remain closed to traffic. Access to Manse Road will be via Nairn Road. The road closure on Stuart Street and associated diversion for through traffic remain in place.

Tarring of the remaining section of Stuart Street between Manse Road and the start of the coastal path is provisionally scheduled for Saturday 6th May. We would like to thank residents for their understanding while this final stage of reinstatement is completed on this section of Stuart Street.

Coastal Path 

The map below shows the progress of work being carried out on the coastal path, both what has already been completed and what is planned this week. Reinstatement of the section of the coastal path shown in green is now substantially complete and this section has re-opened with a sign-posted diversion in place around the area of current work. Future work in this area will be limited to reseeding and any required maintenance of the ground until the grass is re-established.

Coastal path progress for 1st May

Ardersier Common

Pipeline installation along a section of footpath within Ardersier Common has been completed. The affected area of the Common, the picnic area and the car park have re-opened to public. We are in discussions with Highland Council to agree replanting arrangements and these will be delivered at the appropriate time to allow plants and trees to establish successfully.  We would like to thank local residents and other users of the Common for their patience while the temporary closure of this area was in place.

We will be updating this page with progress on a weekly basis.
