The cities of Liverpool and Manchester receive their main water sources from the Dee and Vynwy aquaducts in North Wales and the Haweswater and Thirlmere aquaducts in the Lake District respectively. To enable potable water to be transferred between these two cities the ‘West East Link Main’ was recently constructed allowing water to be transferred from Manchester under gravity and pumped in the reverse direction. For this project we have previously supplied over £500k of Erhard Valves.

At the end of the gravity main a bypass main is to be constructed and a DN700 Erhard Needle Valve controls the flow of water into the North Liverpool Truck Mains.
