SEWER water is once again being pumped in to the River Lavant in a bid to battle high groundwater levels.

The drainage system in the Lavant valley has been overloaded by recent floods and heavy rain – prompting a temporary pump to be put in place on the river at East Dean.

Southern water is already surveying and sealing the sewers around neighbouring villages Charlton, Singleton, West Dean and Lavant to stop groundwater infiltrating in to the sewer network.

“Our temporary pumping arrangement in East Dean protects homes from flooding and ensures people can continue to use their wastewater services such as bathrooms,” said a spokesman for Southern Water. “The pumps remove water from the sewers, which are backed up with flows heavily diluted by groundwater.

“When the water table rises excessively, it can infiltrate the sewers – lifting manhole covers and backing up toilets – potentially flooding streets and properties.

“We invested almost £1m to survey and seal sewers in the Lavant Valley last year and are committed to conducting the next phase of our work later this year once groundwater levels have dropped.”

The water is filtered before being released in to the river. Last year, environmental groups raised concerns about the impact of pumping into the Lavant.
