The JV, called C2V+, was handed the job by United Utilities under the water company’s AMP6 construction delivery partner framework.

The scheme will upgrade the existing Oswestry water treatment facility, which currently treats water from Lake Vyrnwy in North Wales via the Llanforda open reservoir. It supplies clean water to customers in Liverpool and parts of Cheshire. Due to the composition of the raw water and the condition of the existing plant, the works are needed to improve the capacity and water quality.

This will be the first water treatment works in the UK to use a chlorine dioxide based chemical process. This solution has been used in North America and Europe and is an energy neutral process that is expected to provide significant savings to United Utilities through the installation of hydroelectric turbines that feed surplus energy back into the grid.

 The main elements of the project consist of a new flocculation/sedimentation basin, chlorine contact tank and clearwater storage tank. The existing rapid gravity filters are being refurbished to cater for an additional 40 million litres of water flow per day when completed.

Works on site starts in spring 2015 with an overall construction period of two years.
