South West Water is set to begin work on a major project in Falmouth to improve the town’s sewage network, reduce the use of storm overflows and protect the quality of its bathing waters.
The company is set to build a new underground storm water storage tank beneath the car park at Gyllyngvase Beach with works due to start in October.
Once complete, it will capture excess flows during heavy rainfall, holding them safely until there is capacity in the sewer network for full treatment.
This will help to reduce storm overflow spills from South West Water’s Queen Mary Gardens pumping station and safeguard water quality at Gyllyngvase Beach.
To allow the work to take place safely, Gyllyngvase car park will be closed from October 2025 until the works are completed, which is expected to be around the end of March 2026. The project is part of South West Water’s record programme of investment in wastewater infrastructure, with similar schemes already delivering strong results.
