How it works
- 1
Share tank details
Tank type, capacity and location — and for societies, the number of tanks and access points.
- 2
Plan the water shutdown
For societies, schedule a time and inform residents of the supply interruption in advance.
- 3
Mechanised cleaning
The team drains, removes sludge, pressure-washes, vacuums and disinfects the tank.
- 4
Refill and handover
The tank is rinsed and refilled. Societies should keep a dated cleaning record.
Tips for flats and housing societies
- For RWAs: publish the tank cleaning schedule and keep dated records — residents increasingly ask for them.
- Notify residents at least a day before the water supply is interrupted, and clean one tank at a time where possible.
- Underground tanks are confined spaces; insist on trained staff with proper safety equipment.
- Residents: if your society cleans common tanks but your flat has its own loft tank, that tank still needs separate cleaning.
How to prepare
- Use water sparingly the evening before so the tank is nearly empty.
- Make sure the team has safe access to the tank and the lid can be opened.
Frequently asked questions
How often should a water tank be cleaned?
Every 3–6 months is recommended, and immediately if you notice smell, colour or particles in the water.
How much does water tank cleaning cost for a society?
Society tanks are quoted by total capacity, number of tanks and access. Share the details and we arrange an inspection and quote.
Is the disinfectant safe for drinking water?
Professional teams use disinfectants meant for water tanks and rinse the tank before refilling.
How long will water supply be off?
About 1–2 hours for a home tank. For society tanks, it depends on size; schedules are planned to minimise disruption.
