Combined sewer overflow

A designed relief point that discharges diluted sewage to a river when a combined sewer exceeds capacity during heavy rain, preventing flooding of streets and properties.

What it means for you

Reducing the rainwater we send into combined sewers is the practical way to reduce how often these operate.

Not sure whether this applies to your property? Ask us. There is no call-out charge and the price is fixed before any work starts.
