South West Water Addresses Flash Flood Risks

South West Water, a water and wastewater services company serving the South West of England, is highlighting the risks of flash flooding as part of recent Flood Action Week activities. Flash floods occur when heavy rainfall falls over a short period, often overwhelming surface water drainage and combined sewer systems. These events can happen anytime, but dry, hardened soil or saturated ground can increase runoff, raising flood risk. South West Water is focused on managing sewer-related flooding by maintaining and upgrading infrastructure, monitoring weather, and collaborating with local authorities to protect communities and the environment.

Measures include regular sewer cleaning, surveys to identify flood-prone areas, reducing rainwater entering wastewater systems through natural drainage, and catchment management initiatives like tree planting. Customers are also encouraged to avoid flushing anything other than pee, poo, and paper to reduce blockages.

“Although the effects of overland flash flooding aren’t our responsibility, we’re working hard behind the scenes to keep sewers in great condition to reduce and prevent flooding from our sewers during heavy rain. We work closely with local councils on practical solutions to flooding to help protect communities.” said Hazel Tranchant, Head of Tactical Asset Management
