Seaham Water Services

Frequently asked questions

Who supplies the water in Seaham?

Northumbrian Water supplies Seaham. You can reach them on 0345 717 1100.

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

Report it to Northumbrian Water on 0345 717 1100. 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 Northumbrian Water on 0345 717 1100. 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 Seaham?

Your water comes from Northumbrian Water, but wastewater and sewerage in Seaham is handled by Northumbrian Water / Anglian 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 Seaham?

Seaham's water is moderately hard, and the risk of limescale in kettles and boilers is medium. Occasional descaling of kettles and shower heads keeps it in check.
