South West Water Dawlish storm overflow scheme is entering its final phase, with major infrastructure works now completed as part of a multi-million pound investment to improve water quality.
The project has focused on reducing the use of storm overflows by increasing storage capacity and improving the performance of the local sewer network.
South West Water Dawlish storm overflow scheme adds major storage capacity
Two new storm storage tanks have been installed at The Lawn and Sandy Lane, each capable of holding up to 2.2 million litres of stormwater.
These tanks are designed to capture excess flows during periods of heavy rainfall, preventing untreated discharges and allowing wastewater to be stored until treatment capacity becomes available.
In addition to the tanks, a new pump chamber and control systems have been installed, alongside a new sewer connection to the facility at The Lawn.
Network upgrades improve resilience and reduce inflow
Further works across Dawlish have focused on reducing the volume of water entering the sewer network. Surface water separation schemes at West Cliff and Exeter Road will limit rainwater inflow, helping to reduce system pressure during storm events.
Measures to address groundwater infiltration into existing pipework have also been completed, further strengthening network resilience.
These upgrades are expected to play a key role in reducing storm overflow use and improving environmental performance in the area.
Project moves into reinstatement phase
With the main construction works nearing completion, activity is now focused on reinstating affected areas, including turfing, removing site hoardings and restoring public spaces ahead of the summer.
The scheme forms part of South West Water’s wider £760 million “Turning the Tide” programme, which aims to significantly reduce storm overflows across the region over the next four years.
