Southern Water is upgrading the sewer network in Charlton and Singleton, which it says will better protect households from flooding and prevent storm overflows.
Teams of engineers will be sealing sewers and manhole covers in the Lavant Valley to keep groundwater out of wastewater pipes during rainy periods.
This £3.3m project follows the completion of a £1.1m project to seal sewers in the neighbouring village of East Dean in 2024, and is similar to work continuing in nearby Funtington and Bosham.
Historically, this area suffers badly with a build-up of groundwater during the wetter months of the year, and when this seeps into our network it can overload the system.
This can cause flash flooding locally, and also trigger storm overflows further down the valley and into Chichester Harbour when the influx of water is too much for our treatment sites and pumping stations to handle – requiring releases into the environment to prevent more homes and communities from flooding.
Once work is complete in Singleton and Charlton, engineers will continue our work our way down the Lavant Valley.
