Short answer: Three parties share it. Homeowners maintain the pipes and fittings of their own flat. Town Councils maintain the water storage tanks and pipes on common property. PUB maintains the water mains and connecting pipes up to the water meter. So a leak inside your flat is yours; a leak in the corridor riser is the Town Council's.
Plumbline writes these guides from PUB and government sources and published Singapore price data; each claim links to where it comes from.
The three parties
In a November 2024 written reply to Parliament, the environment ministry set it out (MSE):
| Who | What they maintain |
|---|---|
| Homeowner | The pipes and fittings of their own unit |
| Town Council | Water storage tanks and water pipes on common property (tanks are cleaned and disinfected yearly by a licensed plumber) |
| PUB | The potable water network, monitored with sensors and checked yearly for leaks |
PUB’s own handbook puts the boundary at the meter: PUB maintains the mains and connecting pipes up to the water meter, and installations downstream of the meter are the consumer’s (PUB handbook).
Where to report what
- Leak inside your flat (under the sink, behind the toilet, a water heater): yours. Book a plumber; pipe work needs a PUB Licensed Plumber.
- Leak in the corridor, riser or void deck: report it to your Town Council.
- No water or low pressure for the whole floor or block: Town Council first.
- A burst main on the road: PUB.
Check whether it is your side
Turn off every tap, read the water meter, wait 30 minutes without using water and read it again. If the meter moved, the leak is downstream of the meter: on your side.
Use the who-fixes-it checker or request a plumber.
Want a plumber to sort it?
A plumber who covers your area calls you back with a price.
Request received.
A plumber who covers your area will call you on the number you gave. If water is flooding, turn off the main stop valve beside your water meter while you wait.
More questions
My whole floor has low water pressure. Who do I call?
The Town Council, since tanks, pumps and pipes on common property are theirs to maintain.
Water is dripping from my ceiling. Is it a pipe?
Sometimes, but often it is the floor slab of the flat above. In HDB flats the slab between two units is shared by both owners.
