Our reservoirs

South East Water has two reservoirs in Sussex – Ardingly and Arlington.

These reservoirs are popular attractions and offer visitors a chance to take part in fishing, bird watching, or simply enjoy the peace and tranquillity.

However, their main benefit is that they can store up to 8,300 million litres of water.

The reservoirs, which were built in the 1970s, are usually topped up during the wetter winter months and drawn down in the summer.

Together they provide 8% of all the water we supply, with the rest coming from underground aquifers and transfers from neighbouring water companies.
