Water Tank Disinfection Explained

Ringed by the district courts and a cluster of CGHS societies at the junction, Karkardooma stores most of its water in rooftop plastic tanks that draw up from big communal reservoirs and feed a great many homes each. KaamGenie lifts the slime and settled matter out of those Sintex overheads, sanitises hygienic and photographs them, from ₹699.
The junction here is defined by the district court complex and the metro interchange, and behind them stand rows of cooperative societies and DDA blocks. Each society pushes DJB water from a large shared ground reservoir up to rooftop overhead tanks that serve dozens of homes apiece. The rooftop stores are usually Sintex or plastic, and with so many households drawing on them the tanks are in near-constant motion yet rarely rest low enough to expose their floor. Managed by committees rather than any one family, they tend to be looked at only when a resident complains, by which point the walls already carry a film.
We handle these at block scale, taking each rooftop tank empty, vacuuming the fine matter that has ridden up from the reservoir, buffing the plastic sides with soft pads and closing with a hygienic sanitising wash plus photos filed for the committee. Societies wanting the ground reservoir seen to on the same day fold it into our fuller water tank cleaning in Karkardooma. This page is about the rooftop Sintex and plastic tanks that cap each block.
A communal rooftop tank that supplies a whole society is refilled the instant it dips, so its water never stands still yet almost never empties enough to show the floor. Sunlight through the translucent Sintex wall warms that moving water, and a green film settles on the brightest side. The more homes a tank serves, the harder it cycles and the sooner both the film and the sediment appear.
The rooftop tank also picks up whatever the pump lifts from the reservoir, which lodges as a slime along the walls. Fanned out to scores of kitchens, it reads as water that is briefly cloudy on opening a tap and flat to the taste, and it furs appliances sooner across the block. A calendar-based scrub of the overheads is what keeps a large committee's water dependable, instead of reacting to grumbles.
No travel charge anywhere in Karkardooma. The final price is confirmed on the call before we come — it depends only on tank size and access.

“Can you clean all the block's roof tanks in a single call?” Yes. Where a society has several overheads we bring a crew big enough to finish them in one visit, taking each empty in turn and filing a photo of every one for the committee. Most blocks by the courts run it exactly that way.
“What is the committee rate per rooftop tank?” It opens at ₹699 a tank, and for a society doing four or more we set a bulk per-tank price that trims the cost. Many committees lock in a standing date at that rate so a round is never forgotten.
“Is that slime on the walls something to worry about?” It is a bacterial layer that forms where warm water meets the plastic, and while the supply is chlorinated, running water over it daily is best avoided. We buff it away and sanitise the wall so the tank presents a clean surface, not a coated one.
“Should the ground reservoir be done together?” It is worth pairing, because the pump keeps lifting reservoir matter into the overheads. Cleaning both on one visit stops the roof tanks being re-soiled straight after, and we quote the society's reservoir and overheads as a single job.
“Can the work fit the society's supply timing?” Yes. We plan each tank to be at its lowest as we begin and back in service before the next fill, so no home in the block is dry while we work.
