View Annual Sewage Data

You're looking at the totals that we have calculated for sewage in South East Cornwall for 2025. It is an estimate, based on very poor quality live data from the Water Companies. This may not align with the 'official' reported sewage values from the water companies, which is reported in April following then end of the year - so 2025 numbers are reported in April 2026.

What's a potential overflow? If the CSO goes 'Offline' while its Overflowing, we don't know if it stopped overflowing until we get a 'Stop' event.

Totals for South East Cornwall in 2025

Monitoring offline3,195 hours
