The scheme for United Utilities will enhance the existing Oswestry facility, which currently treats water from Lake Vyrnwy in North Wales via the Llanforda open reservoir.

The C2V+ joint venture will deliver the first WTW facility in the country to use a chlorine dioxide based chemical process. This will improve the quality of water produced at the works, which supplies water to customers in Liverpool and parts of Cheshire.

This innovative solution has been successfully used in North America and Europe. As an energy neutral process it will 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.

Existing rapid gravity filters are also being refurbished to cater for an additional 40m litres of water flow per day when completed.

Darren Hynes, framework director for C2V+ said: “After being named as one of four construction delivery partners for the AMP6 framework in 2014, we are delighted to be appointed for this scheme at this early stage of the framework.

“It demonstrates the collaborative approach between C2V+ and United Utilities whilst providing sustainable employment opportunities for the local economy by creating over 50 jobs over the next two years.”

Works on site will start soon with an overall construction period of two years.
