Our sewerage services
Sewage is the water found in sewers. Sewerage is the network of sewers, pipes and pumps that lie unseen beneath virtually every street and road. Sewers carry sewage from where it is produced to the sewage treatment works to be treated and cleaned.
The sewerage systems can be either combined, carrying both sewage and rain water or separate systems.
The government transferred ownership of private sewers and lateral drains from private individuals to water and sewerage companies on 1 October 2011.
During extremely heavy storms there may be more rain than the sewers can handle so the combined sewer overflows are designed to discharge this rainwater into watercourses.
Sometimes builders, plumbers or householders wrongly connect pipes, which carry waste water from toilets, baths, showers, sinks, washing machines or dishwashers, to the surface water system instead of the foul sewerage system. This can happen when a property is extended or renovated, when a new house is built or when additional toilets, sinks and appliances are added to a property and can result in pollution to rivers and streams.
If pipes which collect rainwater from roofs, roads and drives are wrongly connected to the foul sewerage system, water can overwhelm the sewer network and can contribute to flooding – this can also result in pollution.
Please help to protect water quality in our rivers, streams and bathing waters by making sure you have made the right connections.
