Many of our drains in Southwell are combined –
1) surface water run-off from houses, gardens, driveways, roads
2) sewage
So in a heavy rainfall event (over 25mm in 30 minutes), the surface water may overwhelm the drainage system and cause the manholes to ‘pop’ and sewage leak out into the roads.
We can help keep our drainage system flowing and working more effectively
2) help protect your drains from blockages – how to make small changes in your daily household routine.
