Mayflower Water Treatment Works
Work has also started to lay the pipes needed to transfer treated drinking water from the new Mayflower Water Treatment Works into Plymouth's water distribution system.
The new, state-of-the-art Mayflower Water Treatment Works at Roborough, just north of Plymouth, will replace the outdated treatment works at Crownhill in Plymouth, which was built in the 1950s and is reaching the end of its useful life.
PWNT, a leading water technology company based in the Netherlands, will be responsible for the design, installation and commissioning of the main water treatment process.
Mayflower will use cutting-edge treatment processes, designed and developed by PWNT, and tested at a prototype facility at Crownhill from June 2013 until June 2015.
The new technology uses suspended ion exchange with resin regeneration system, inline coagulation and ceramic membrane microfiltration. It is the first time that this combined technology has been used in the UK.
Global design and consultancy firm Arcadis is the main design contractor, in partnership with consulting engineers Pell Frischmann. Together they will be responsible for all the design work outside of the key treatment process.
Infrastructure group Balfour Beatty is the main construction contractor, in partnership with Interserve, responsible for the construction of all infrastructure, buildings and pipelines for the new water treatment works.
The main construction is scheduled to finish by December 2017 and Mayflower Water Treatment Works will become operational in September 2018, with the existing Crownhill works retiring from service a few months later.
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."
