Black & Veatch completes Scottish water treatment plant

Black & Veatch has completed the design and construction of the new Glencorse Water Treatment Works (WTW) in Edinburgh, Scotland.

The £130m WTW was developed by Black & Veatch in partnership with Scottish Water, the owner of the treatment works.

With a production capacity of around 175 million litres of water per day, the plant supplies drinking water for 450,000 people across the city and parts of Midlothian.

Black & Veatch client centre director for Scotland Mike Barcroft said sustainability and community have been at the project’s heart throughout.

"We sought to deliver more than just a sound engineering solution. The company recognised the bigger picture: the needs of the public and the environment; and incorporated them into the way we acted as a partner to Scottish Water," Barcroft said.

The treatment works include treatment systems housed in a partly buried structure, a separate building for the inlet, a 90 megalitre reinforced concrete Clear Water tank and twin 7.5km pipelines that carry treated water from the WTW to the city.

Counter current dissolved air flotation and filtration was used as the treatment process to reduce the size and visual impact of the WTW.
