Our current reservoir levels (correct 10/05/2022)

The water level at Ardingly Reservoir has fully replenished for the summer months.

South East Water took several actions following the summer heatwave in 2020 to ensure the company is in a healthy position for 2022.

Actions included targeted leakage reduction across all of the company’s Production sites and pumping additional water into its vast network of pipes through various groundwater sources.

The company also worked closely with its customers and key stakeholders to encourage water efficiency across five counties and will continue to do so.

Saving water is vital all year round to in order to minimise disruption to supply when demand is at its highest.

Top tips include using a water butt in your garden, fixing leaky loos and re-using water wherever possible.
