Sibu loses close to half the water it treats before it reaches anybody — 46 per cent, on the last figure put in public, in 2024. The town is built on deep peat, the peat settles, and the mains break as it moves — which is why a cut in one part of town tells you very little about the next. That is the gap this board is for: if you have no water, tap your area, and you and your neighbours can see whether it is just your tank or the whole area.
Reports need a sign-in, one per area per person, and they clear themselves after twelve hours. This is neighbours reporting to neighbours — it is not Sarawak Water, and tapping an area does not report a fault to anyone. Ring 013-810 6311 to do that.

These reports come from neighbours, not the water utility. Anyone can read the board; reporting no water takes a free account, which keeps it honest. A report clears itself after about 14 hours, so the board stays current on its own. When several people report the same sector, it’s likely the whole sector is dry — not just one tank.
Where Sibu's water comes from, and why so much of it is lost
Two treatment plants supply the town. Salim is rated at 150 million litres a day and is being doubled to 300 under a Sarawak-funded upgrade — RM291.4 million, 68 per cent built by May 2026, partial completion due at the end of 2026 and the full 300 million litres by the middle of 2027. Work on that upgrade is itself a regular cause of night-time cuts, and will be for another year. Bukit Lima adds 45 million litres a day.
The losses are the harder problem. Sibu's non-revenue water — treated water that never reaches a customer — was put at 46 per cent by the Bawang Assan assemblyman in August 2024, against a national average of 35 per cent; Sarawak Water's own target is to bring the state under 25 per cent by 2030. Most of it leaks from mains that crack as the peat beneath them settles. Sibu is sinking slowly and its pipes move with it. That is a decades-long replacement job rather than a repair, and it is the reason cuts here are frequent, local and hard to predict.

The water utility — Sarawak Water Sdn Bhd (Central Region)
The company that took over Sibu Water Board on 1 August 2025. Its 24-hour line is the only way to report a fault. Its Telegram channel carries every scheduled and unscheduled cut, with the streets affected and the expected hours, and a follow-up post when the repair is done — you can read it in a browser without an account.
Rural / community water — JBALB Sarawak (rural water supply)
The department that supplies the rural areas outside the town network — Pasai Siong, Ulu Siong and Lubok Pelaie among them. It runs tanker deliveries when a rural plant goes down, and its careline answers 24 hours.
Sarawak Water treats the supply to Malaysian drinking-water standards, and a cut is a supply problem rather than a quality one. After the water comes back it can run cloudy or brown for a while as the mains refill and disturb sediment — that clears on its own. If it does not clear, or if it smells, ring 013-810 6311 before drinking it.
