We'll update this page every week with the surface water levels in our main reservoirs, Arlington Reservoir and Ardingly Reservoir.

The reservoirs are usually filled with water from the River Cuckmere, in the winter, ready for the extra demand in the summer months.

Our current reservoir levels (correct 04/02/2024)

Our reservoirs in Sussex, Arlington and Ardingly store up to 8,300 million litres of water and together provide 8% of all the water we supply.

Currently, these reservoirs are approximately 100% full, respectively.
