The new £60million state-of-the-art Mayflower Water Treatment Works will serve Plymouth and the surrounding area.
A substantial proportion of Plymouth’s water supply is provided by the Crownhill Water Treatment works. Originally constructed in open fields during the 1950s it has been overtaken in the 21st century by construction, housing development and technology.
To meet the long-term water needs of one of our fastest growing cities, a new works was required. Resilient by design and the first plant of its kind in the UK, the Mayflower works at Roborough is due to open later in 2020. The treatment works uses ceramic filtration technology, coupled with resin ion exchange processes designed to produce more water, more efficiently and at a lower cost than traditional technology.
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.
But what does this mean for customers?
Keeping bills down in the long term – the plant will cost less to maintain, use less raw materials and require fewer staff to operate it.
Compact process therefore lower construction costs.
Requires less chemicals than traditional water treatment processes, reducing the environmental impact.
Ion exchange process captures hard to remove pesticides, colour and taste providing consistent high quality water.
The ceramic filters provide an absolute barrier to cryptosporidium and harmful viruses.
Located on a hill away from the city – reduces congestion from company vehicles and is safe from flooding.
