300 days on, Plymouth’s new Mayflower water treatment works of South West Water takes shape

Posted on 29 January 2017

dws-pwnt-south-west-mayflower-ceramacWorkers building a new 60 million UK pound state-of-the-art water treatment works for Plymouth and the surrounding area raised their hard hats in celebration to mark 300 days of progress since construction started. Mayflower is on schedule to become operational in September 2018.

Six-CeraMac process
The plant will use cutting-edge treatment processes, designed and developed by Dutch water technology company PWN Technologies. The new drinking water facility will include the Six-CeraMac process that combines ion-exchange and ceramic membranes for the non-chemical pre-treatment of surface water.

The new Six-CeraMac 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.

300 days
In the 300 days since the construction team for South West Water’s Mayflower Water treatment works put the first spade in the ground, in April 2016, the team has:
• laid 5,000 m3 of concrete
• fixed 965 tonnes of steel
• moved 72,000 tonnes of earth
• laid 7,380 m of new pipeline
• issued 808 drawings and 4,042 documents
• worked 122,555 hours without injury

Worldwide interest
The project, the first of its kind in the UK, is also attracting widespread interest from other UK water companies and around the world, as it will use innovative water treatment processes to deliver even cleaner water more efficiently, helping to keep customer bills down.

South West Water’s Managing Director Stephen Bird said: “After years of planning and months of hard work on site it is exciting to see our flagship water treatment works taking shape.

“We’re approaching the halfway point of the construction timetable and while there is plenty more to do, real progress is being made and the team have been working tirelessly in all weathers to ensure we're on target to finish the main building work by next Spring."
