New dawn for Mayflower as treatment plant begins operations
South West Water’s Mayflower Water Treatment Works at Roborough, just north of Plymouth, uses cutting-edge treatment processes to be more sustainable than a traditional water treatment works.
The plant takes over from the old treatment works at Crownhill in the coastal city, which has been serving the area since the 1950s.
The plant was designed and developed by Dutch water technology company PWNT, which tested at a prototype facility at Crownhill from June 2013 until June 2015.
Suspended ion exchange, inline coagulation and ceramic membrane microfiltration are used to produce more water, more efficiently and at a lower cost than traditional technology.
It is the first time that these combined technologies have been used to produce high quality drinking water anywhere in the world.
Mayflower has been producing treated water since August, which has been blended with water from Crownhill to ensure a smooth transition for customers.
Now Crownhill will be officially retired and 100% of Plymouth’s drinking water will be supplied by Mayflower.
South West Water’s director of operations - drinking water services, James King, said: “It has been years in the making – planning, building and commissioning – but now is a truly significant milestone for South West Water, our customers and the wider water industry.
“We already produce some of the highest quality drinking water in the UK, but Mayflower does so extremely consistently and efficiently.
“Mayflower will meet the needs of Plymouth’s growing population and provide a secure, high-quality drinking water supply for the wider Plymouth area for generations to come.”
