Heavy rainfall results in increased runoff from roofs and surfaces leading to more water entering the sewer network, which can cause storm overflows to automatically operate. If this rainwater is captured before it enters sewers, it could reduce how often they operate.
You could use the rainwater you collect on your garden which saves water, and money if you’re on a meter. And if you can prove that the majority of the rainwater from your property doesn't drain to a public sewer, you can apply for a reduction on your sewerage bill.
We recognise it is largely our responsibility to reduce storm overflows, which is why we are spending £3m a month to tackle the issue. Learn more about how we're reducing storm overflows.
However, there are also some things you could do to reduce the amount of surface water that enters the sewer network.
