Vyrnwy water pipe works

Vyrnwy pipes imageWe all appreciate a little care and attention and it's the same for our important water pipes like the Vyrnwy Trunk Mains. We're completing a cleaning and maintenance programme targeting our largest and most important water mains,  providing even greater improvements to the quality of our drinking water to over seven million customers everyday. 

The Vyrnwy Large Diameter Trunk Main (LDTM) consists of three parallel pipelines with a total combined length of around 240km. These large mains carry up to 210 million litres of water a day to 900,000 people in Cheshire and Merseyside. The water in Lake Vyrnwy provides the source which is then transported along the pipelines from Oswestry water treatment works in Shropshire to Prescot Water Treatment Works near Liverpool.

The pipes are almost 130 years old and over time deposits of natural iron, found in untreated water from the reservoirs have built up inside. Although the iron deposits are not likely to be harmful to health, they can cause the water supply to appear discoloured.

We're using a variety of methods to refurbish these large pipes.  We'll be busy working in stages along the pipeline and expect to complete all the cleaning and refurbishment by early 2016.
