We take water from the environment and return it back to nature in the best possible condition.
We have set the ambitious goal of having the best rivers and beaches in the country in our operating area, and zero pollutions as a result of our assets and operations.
We're well on our way to achieving that!
And we have some of the lowest levels of pollution events of water companies in England as measured independently by the Environment Agency.
Storm overflows protect customers’ homes and the environment from flooding.
During heavy rainfall, storm overflows are like a relief valve on our network, and used only when it's completely necessary, releasing excess stormwater into nearby rivers or the sea. They're closely monitored and used in line with permits from the Environment Agency.
As well as protecting customers’ homes and the environment, they protect our sewer network from intense demand, caused by heavy rainfall. A small amount of our network contents can be mixed into this overflow, but, due to the amount of rainwater, this will be significantly diluted down.
We've invested over £350 million into bathing water improvements. Thanks to this investment, our storm overflows should not affect bathing water quality in the bathing season, except during intense rainfall events.
Pollution incidents associated with SOs have fallen significantly through our industry-leading monitoring and pollution management approach.
