We get information about overflowing CSOs since January 2025. Here is a chart of the last three months of data for Rayleigh and Wickford, here you can see overflows in red, the darker the red, the more the CSO overflowed that day.
Each CSO has a row, the most recent data is on the right hand side.
We managed to raise ยฃ150 in 2024. That's not enough to keep the site running. Please consider a one-off or small recurring donation.
