The end of an era

Customers in North Wales are now enjoying higher quality water, thanks to the completion of a complex scheme to close an old treatment works and instead supply water from a more resilient and efficient facility. Constructed in the 1920s, the works at Legacy on the outskirts of Wrexham was licensed to abstract water from nearby former lead mines. This water was then treated through a series of pressure filters and chlorination plants before being held in a 350,000 gallon tank. However, despite regular upgrades, the facility was nearing the end of its useful life and some customers were experiencing occasional discolouration problems. In March 2018, following several years of hard work by the team at Dee Valley Water, a project to transfer the raw water to Llywn Onn was completed – including a new distribution water pipe – and the Legacy treatment works was finally closed.
