Providing you with better water quality
We have invested to reduce the use of storm overflows in Dawlish, helping to improve water quality in local rivers and the sea.
Storm overflows work like a safety valve on the wastewater system. They are typically used when heavy rain overwhelms the system. We’re committed to reducing reliance on storm overflows, helping to improve water quality in rivers and the sea, especially in bathing waters.
Finding solutions for each area
To reduce storm overflow spills across the region, tailored solutions are needed for each area. In Dawlish, this included installing new storm storage tanks, carrying out surface water separation work throughout the town, and repairing and upgrading sections of the existing sewer network.
The main construction work is now complete, and the regulatory requirements have been met across all sites. Reinstatement work is continuing in The Lawn.
Two new storm storage tanks have been installed: one beneath The Lawn, with capacity to store up to 2.2 million litres of storm flows, and another at Sandy Lane, with capacity to store up to 2.3 million litres. Together, these tanks provide an additional 4.5 million litres of storage, helping to reduce storm overflow spills and protect the local environment.

Testimonials
I would like to thank all the positive work being carried out by Southwest water staff and employed contractors. All have communicated closely with both the community and town council on the vast project that is being undertaken. We have benefited from having Lynda Sudlow available in person twice a week, who has not only been able to keep us all updated, she has introduced us to Carl and most of all the contractors on site. In relation to the contractors, they have been more than accommodating to us, moving and securing the flagpole and ensuring all areas are clean and serviceable for our events. Some speak Welsh which for me is an extra bonus.

The way they are working is of benefit to Dawlish and SWW are doing all they can to work with the shops in the strand to make sure the shops can continue to trade.
SWW have also made allowances when Dawlish council have had events on the lawn which meant the work had to stop for a short while.
In all aspects of the work the contractor has worked to make sure all people living in Dawlish have the least disruption.
