Mayflower Water Treatment Works

South West Water is building a new £60million state-of-the-art water treatment works to serve Plymouth and the surrounding area.

Work started on site at Roborough, just north of Plymouth, in April 2016 and Mayflower Water Treatment Works is on schedule to become operational in autumn 2019.

Mayflower will replace the outdated treatment works at Crownhill in Plymouth, which was built in the 1950s and is reaching the end of its useful life.

It will use cutting-edge treatment processes, designed and developed by Dutch water technology company PWNT, and tested at a prototype facility at Crownhill from June 2013 until June 2015.

The new technology features SIX® suspended ion exchange with resin regeneration system, ILCA® inline coagulation and CeraMac® C90 ceramic membrane microfiltration. It is the first time that this combined technology will be used in the UK.

Infrastructure group Balfour Beatty is the main construction contractor, who are working in partnership with Interserve, to deliver the construction of all infrastructure, buildings and pipelines for the new water treatment works.

Global design and consultancy firm Arcadis has the main design contract, and they are working in partnership with consulting engineers Pell Frischmann. Together they are responsible for all the design work outside of the key treatment process.

Around 150 people are expected to be employed during construction.

South West Water staff voted for the name because of its echoes of pioneering, innovating and exploring new worlds, whilst paying homage to Plymouth's past, as well as linking in with the Mayflower 400 initiative leading up to 2020.

Senior Project Manager Mike Court said: "This promises to be a very exciting and globally significant project.

"The new treatment works 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."
