How Often Should You Clean Your Water Tank?

Tara Apartments’ landmark brick towers store water in some of south Delhi’s oldest rooftop RCC tanks — hairline cracks, rough corners and deep sediment pockets included. KaamGenie specialises in cleaning exactly this kind of ageing cooperative-society tank. From ₹699.
Tara Apartments on the Alaknanda side is one of south Delhi’s earliest cooperative group-housing societies, its distinctive clustered brick towers designed decades ago around shared underground sumps and large rooftop RCC tanks serving each cluster. The society runs organised cleaning cycles — a real advantage — but the tanks themselves are showing their age: hairline cracking, roughened internal concrete, and corner geometries where sediment packs in and ordinary cleaning never quite reaches.
Old RCC needs a specific approach and that is what we bring: careful dewatering, extraction of the packed corner deposits, mechanical scrubbing that cleans without gouging weathered concrete, a crack-condition photo survey for the society’s records, and certified disinfection before refill. Our water tank cleaning in Tara Apartments page covers sumps and society-wide work; here the focus is the cluster rooftop tanks.
Concrete tanks age differently from plastic. Decades of filling and drawing leach the cement surface until it turns rough and porous, and a porous wall is a permanent anchor for deposits and microbial film — wiping achieves nothing, and harsh chemicals attack the concrete itself. Only controlled mechanical scrubbing cleans these surfaces without shortening the tank’s remaining life.
The cluster architecture concentrates the load: many flats draw through each rooftop tank, so sediment accumulates fast, and the tanks’ angular corners — a signature of their era — hold wedge-shaped deposit pockets that a quick service will miss entirely. Our crack survey adds a second layer of value, giving the society photographic early warning of sections that need a mason before they need an engineer. Twice-yearly cleaning per cluster is the standard we recommend here.
No travel charge anywhere in Tara Apartments. The final price is confirmed on the call before we come — it depends only on tank size and access.

“Our RCC tank has visible cracks — can it still be cleaned?” Yes, and it should be — deposits sitting in cracks accelerate the deterioration. We clean with methods safe for weathered concrete and photograph every crack we find, so the society can decide on repairs with real information. If we judge a tank unsafe to enter, we say so immediately.
“What do you charge at Tara Apartments?” Flat-level plastic tanks run ₹699 up to 500L and ₹899 for 501–1,000L. The large cluster RCC tanks are measured and quoted per tank for the society, with rates agreed in writing before the first drain. The crack-condition photo survey is included, not extra.
“How do you clean concrete without damaging it?” Mechanical scrubbing with non-metallic brushes and controlled-pressure jetting — enough force to strip deposits, calibrated to spare the cement surface. We avoid acids and aggressive chemicals entirely on RCC, because they eat the very material holding your water.
“Will a whole cluster lose water during the clean?” Briefly and predictably. We coordinate with the society office to schedule each cluster’s tank at its low point, notify the affected flats a day ahead, and complete the physical work in a few hours so the evening refill lands on time.
“How often should our society run this cycle?” Twice a year per cluster is right for tanks of this age and load — commonly booked pre-summer and post-monsoon. We maintain the society’s schedule on our side and prompt the office when a cycle falls due, so continuity survives committee changes.
