Project Planned to Improve Water Security for Residents in Wales

A major refurbishment of Dee Valley Water’s largest water treatment works will provide long-term security and quality of water supplies to Wrexham, Wales, and the surrounding area. Tendered as a single project, Black & Veatch has been appointed as design and build partner to upgrade and replace the ageing water treatment assets at Llwyn Onn water treatment works.

“Our fully integrated design and construction delivery model was a key differentiator in our being awarded this important project,” Black & Veatch Bid Manager Mat Fairfax said.

The rebuilt works will be constructed within the constraints of the existing site and the new structures will be designed and built whilst the existing treatment facility remains in operation. As well as improving water security, the introduction of a secondary treatment process will further ensure customers continue to benefit from the highest standards of water quality.

The upgrade forms the largest single project being delivered under Dee Valley Water’s five-year AMP5 Capital Investment Program, which is mainly targeted at the renewal of assets that are approaching the end of their useful lives.

The contract will be executed in two phases. The six-month design period began in April 2011, and will be followed by an 18-month construction period. All works are planned to be complete by April 2013.

The appointment furthers Black & Veatch’s 20-year relationship with Dee Valley Water in supporting the water company’s need to meet environmental requirements and fulfil customer expectations with a secure and high-quality water service.
