UU submits major treatment works plan

David McCourt

United Utilities has lodged plans for a facility costing between £123m and £171m at Davyhulme Waste Water Treatment Works in Trafford.

The procurement brief was also published this week to appoint the contractor to design and build the facility, which is required to satisfy stricter environmental regulations.

The plans include internal site roads within the new facility area, a new treatment facility and site entrance, construction of a new primary sub-station building and modifications to existing high-voltage electrical infrastructure. The project will take 30 months to complete.

Davyhulme is United Utilities largest WwTW, treating wastewater from a population equivalent of about 1.1 million from the Greater Manchester conurbation.

Sludge treatment at Davyhulme is currently undergoing refurbishment and expansion as part of the Sludge Balanced Asset Programme project to treat raw sludge.

The environmental commitment is driven by Davyhulme's inclusion in the National Environment Programme as a result of the Manchester Ship Canal being designated under the Freshwater Fish Directive in 2003.

This revised consent will also meet the requirements of the European Water Framework Directive.

United Utilities is also spending £100m on a programme that uses the sludge left behind after the treatment process to help power the site, due to complete in 2013.

Interested parties are invited to an introductory presentation to be held at the Best Western Everglades Park Hotel, Widnes, on Monday 26 November at 10:00 am, and must confirm their intention to attend by close of business Thursday 22 November. Contact email: alison.ardrey@uuplc.co.uk
