Ness Water Treatment Works

What does the work involve?

Scottish Water is investing £6.5 million to take care of the future of the water supply for Ness, Isle of Lewis.

Our delivery alliance partner Efficient Service Delivery (ESD) will be working to expand the existing Water Treatment Works at Airigh Na Gaoithe and fit upgraded water treatment equipment and controls. There will also be a new filtration system and generator which will be housed in an extension to the existing main building, as well as a separate new raw water storage tank. 

 

Why are we doing this work?

This project will ensure Scottish Water can continue to supply clear, fresh and great-tasting water to customers in Ness for years to come, with improved ability to maintain water supply in the event of any significant disruption to the site’s power supply.

The upgraded Water Treatment Works will have improved capacity to accommodate natural variation in the quality of the raw water along with additional resilience to withstand periods of severe weather and is sized to meet the community’s projected future needs.

 

Latest Update

Construction and testing of the new raw water tank has been completed and this was put into service in August 2021.  The tank will provide 72 hours storage of raw water.

Work is on-going on the other elements of the project, which is expected to be completed by the middle of 2022.

The site is relatively distant from residents, but we appreciate there will be some additional construction traffic while work is underway. Every effort will be made to keep any disruption to a minimum and to ensure drivers are mindful of safety at all times.

Access to the site is from the A857 in Habost, on to Cross Skigersta Road, continuing beyond the Habost Recycling Centre.
