Investing in Inverurie

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.

Inverurie

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: https://youtu.be/mEw44xGG_no

The project is due to start on the 4th September 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.
