Frequently asked questions

Who supplies the water in Portsmouth?

Portsmouth Water supplies Portsmouth. You can reach them on 023 9249 9888.

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

Report it to Portsmouth Water on 023 9249 9888. 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 Portsmouth Water on 023 9249 9888. 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 Portsmouth?

Your water comes from Portsmouth Water, but wastewater and sewerage in Portsmouth is handled by Southern Water — a separate company. The drains inside your property boundary are the owner's responsibility — that is the work we do.

Is the water hard or soft in Portsmouth?

Portsmouth'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 Portsmouth.
