Water Tank Cleaning Services in Bangalore
Reshma Facilities Management cleans every kind of tank an apartment or building has: overhead tanks, underground sumps, STP and WTP tanks, drainage chambers and new construction tanks. We use a mechanised multi-stage process and give you photographs of the tank before and after every clean.

Our tank cleaning process
Step | What happens |
|---|---|
1. Drain | Remaining water pumped out, tank isolated from supply |
2. Sludge removal | Settled sludge removed by vacuum pump, not stirred and flushed down the line |
3. Scrubbing | Walls, floor and corners scrubbed by hand and machine |
4. High-pressure wash | Full internal surface washed |
5. Disinfection | Anti-bacterial treatment applied and rinsed |
6. UV or final rinse | Final disinfection where applicable [CONFIRM] |
7. Photos | Before and after photographs of the tank interior |
8. Refill and check | Residual chlorine confirmed at the outlet |
Staff entering tanks use safety gear, and confined-space precautions are followed for every clean.
Why photographs
Nobody from the committee is going to climb into the tank. A cleaning report without photos is a claim with nothing to check it against. We attach photos of the inside of the tank, before and after, to every report.
WTP tank cleaning
Water treatment plants have their own tanks: raw water tanks, treated water tanks and filter vessels. Sediment and biofilm build up in these just as they do in sumps, and a dirty treated water tank undoes the work the plant just did. We clean them on the same schedule as your sumps, coordinated with the WTP operator so supply is not interrupted.
Construction tank cleaning
New buildings hand over tanks full of cement slurry, sand, debris and sometimes leftover formwork. Water from these tanks should not reach flats until they are cleaned. We clean construction tanks before first fill, which is useful for builders at handover and for associations taking over a new property.
How often should tanks be cleaned?
Twice a year is common practice for apartment sumps and overhead tanks. Buildings on borewell or tanker water need it more often because more sediment comes in. Older tanks, especially over 15 years old, need cleaning more often still.
Cleaning without cutting water for a day
We clean tanks one at a time and plan around peak usage, so most buildings do not lose water supply for a full day.
Cost of tank cleaning in Bangalore
Tank cleaning is priced by tank capacity in litres and the number of tanks. Sumps and larger tanks cost more because sludge removal takes longer.
Frequently asked questions
A typical overhead tank takes two to three hours. A large sump can take most of a day.
Yes, after the final rinse and refill. We check residual chlorine at the outlet before handing over.
