Water Tank Cleaning & Maintenance
Scheduled cleaning, disinfection and routine maintenance of potable water tanks, rooftop tanks and storage tanks, carried out to PUB requirements with minimal disruption to supply.
Overview
Water storage tanks accumulate sediment, scale, biofilm and organic matter over time. Even where the incoming supply is clean, these deposits can affect water quality, encourage bacterial growth and reduce the usable capacity of the tank.
SPS Jetting provides complete water tank cleaning for residential, commercial and industrial properties across Singapore. Our process covers isolation and draining, removal of sludge and sediment, scrubbing and high-pressure washing of internal surfaces, disinfection, rinsing and the proper disposal of extracted waste.
Between cleanings, routine maintenance visits check covers, locks and seals, ball valves and float switches, overflow pipes and access ladders, so small defects are put right before they affect water quality or supply.
Cleaning is carried out in accordance with PUB requirements for potable water installations. We coordinate with building management and MCSTs to schedule works around occupancy and to keep supply interruption as short as possible.

Water Tank Cleaning & Maintenance — Frequently Asked Questions
Common questions about water tank cleaning & maintenance in Singapore, answered by our plumbing and drainage specialists.
How often should a water tank be cleaned in Singapore?
For most buildings, potable water storage tanks should be cleaned and disinfected at least once every six to twelve months. Buildings with higher occupancy, older tanks or a history of sediment build-up may require more frequent cleaning.
Where a tank serves a food establishment, healthcare facility or childcare centre, a shorter interval is generally advisable. If the tank has been out of service, contaminated or opened for repair works, it should be cleaned and disinfected before being returned to use.
What does a professional water tank cleaning service include?
A complete service goes well beyond rinsing the tank. It should cover the full cycle from isolation to recommissioning.
- Isolation of the tank and controlled draining.
- Removal of residual water, sediment and sludge.
- Manual scrubbing and high-pressure washing of walls, floor and baffles.
- Disinfection of all internal surfaces.
- Rinsing and safe disposal of waste water.
- Visual inspection of the tank interior, covers and fittings.
A short report or photographic record is useful for maintenance records and for demonstrating due diligence to building owners.
How long does water tank cleaning take and will the water supply be interrupted?
A typical domestic or small commercial tank can be cleaned within a few hours. Larger tanks, multi-compartment tanks or tanks with heavy sediment may require a full day.
Some interruption to supply is unavoidable because the tank must be drained. Where the installation has twin compartments, cleaning can often be staged so that one side remains in service. For single-tank installations we usually schedule works overnight or during low-demand periods, and building occupants should be notified in advance.
What are the signs that a water tank needs cleaning?
- Discoloured, cloudy or foul-smelling water at the taps.
- Visible sediment or particles in stored water.
- Slime, algae or biofilm on internal surfaces.
- Reduced water pressure or blocked strainers and filters.
- The tank has not been cleaned within the last twelve months.
- Recent repair, painting or building works around the tank.
Water quality complaints from occupants are often the first indication. If several units report the same issue, the shared storage tank should be inspected before individual plumbing is investigated.
Do you clean water tanks for condominiums and MCST-managed buildings?
Yes. We regularly carry out tank cleaning for condominiums, HDB estates, commercial buildings, factories and institutional properties. Works can be scheduled around occupancy, with advance notices issued to residents where required.
We can also combine tank cleaning with pump checks, tank repair or replacement so that related works are completed in a single shutdown rather than several separate interruptions.
What does routine water tank maintenance include?
Between cleanings, routine maintenance keeps the tank and its fittings in good working order. Typical checks cover tank covers, locks and seals, ball valves and float switches, overflow and warning pipes, ladders and access points, and any signs of leaks, corrosion or cracking.
Small defects found during these checks can usually be put right on the spot. Anything more significant is referred for repair, so problems are dealt with before they affect water quality or supply.
