Horsham Water Services

Frequently asked questions

Who supplies the water in Horsham?

Southern Water supplies Horsham. You can reach them on 0330 303 0368.

I can see water leaking in the road — who do I tell?

Report it to Southern Water on 0330 303 0368. Leaks in the road or pavement are on the public network, which is theirs to fix — anyone can report one, and it costs nothing.

I have no water — what should I do?

Check with a neighbour first. If they have no water either, the problem is likely on the mains — call Southern Water on 0330 303 0368. If it is only your property, check your internal stop tap is fully open; if it is, the fault may be on your own supply pipe — the part we repair and replace.

Who handles sewerage and drains in Horsham?

Southern Water handles both the water supply and the wastewater in Horsham, so it is one company for both. The drains inside your property boundary are the owner's responsibility — that is the work we do.

Is the water hard or soft in Horsham?

Horsham's water is hard, and the risk of limescale in kettles and boilers is high. A filter or softener can help — see our water filter guide for Horsham.
