Combined Sewer Overflows (CSO) help protect homes, buildings, and land from flooding.
They're 'backup sewers', and collect overflowing wastewater when our normal sewers are overloaded. This is often the result of severe rainfall.
Without CSOs, we would face big issues around sewer flooding.
Our CSOs operate with the consent of the Environment Agency.
We work with the Cleaner Seas Forum to provide voluntary, real-time Combined Sewer Overflow information, so people know if and when our bathing waters are affected
