Society and RWA tank cleaning for the kothis and builder floors of Kailash Colony — per-floor overhead tanks and shared plot sumps cleaned together in one coordinated visit. From ₹1,500 per tank.
Kailash Colony is an upmarket colony of kothis and builder floors around a busy market, next to Greater Kailash. Supply is DJB with borewell backup. As across this belt, each builder floor keeps its own rooftop overhead tank while the plot shares one underground sump. A Kailash Colony plot therefore holds several tanks feeding a few separate households — a compact shared system where the below-ground sump, jointly owned and rarely opened, is the tank that quietly gathers silt while the rooftop tanks over each floor stay in view.
KaamGenie cleans the whole Kailash Colony plot in one visit — the shared underground sump with confined-space safety, and each floor’s rooftop tank — coordinated with the owners or the plot RWA. We ventilate and test the sump before entry, clear the settled silt, jet and scrub the walls, disinfect hygienic, and hand over one dated quality report the floors can share. For a single tank, see water tank cleaning in Kailash Colony. This page is specifically about society and RWA whole-building tank cleaning.
The shared sump on a Kailash Colony plot feeds every floor above it, so it fills and empties heavily each day and settles a silt layer no single household notices. Borewell backup adds hardness and the sump takes the first fill, so sediment collects thickest there before the pump lifts it to each floor’s rooftop tank. A neglected sump quietly taints the water for all the floors at once. Cleaning the sump and rooftop tanks every three to four months keeps every household’s supply clean.
As on any shared Kailash Colony plot, the sump has no single owner, so each builder-floor owner assumes another will arrange it and years slip by. We take on the coordination: one survey, one visit clearing the sump and all the floor tanks, and a single quality report the owners split. Doing it together is cheaper than separate call-outs, and a four-visit annual AMC keeps the shared sump on a fixed schedule so the plot never has to deal with a badly silted tank.
No travel charge anywhere in Kailash Colony. The final price is confirmed on the call before we come — it depends only on tank size and access.

“Do you clean plot tanks near the Kailash Colony market?” Yes. We regularly clean builder-floor plots across Kailash Colony, including the blocks around the market, covering the shared underground sump and each floor’s rooftop tank. A short survey checks the sump’s access and the number of floor tanks before we agree a single coordinated visit with the owners or the plot RWA.
“What does it cost to clean a whole plot in Kailash Colony?” Each rooftop tank of 2,000 to 3,000 litres is ₹1,500 to ₹2,000, and the shared sump is quoted by capacity. Since a Kailash Colony plot has one sump plus a few floor tanks, we bulk-quote them together, usually 15 to 20 percent off the per-tank rate for cleaning the whole plot in a single visit.
“Can one builder-floor owner book if the others have not?” Yes. A single owner can book their own rooftop tank without the plot agreeing, and we provide before-and-after photos. The shared underground sump needs all the owners to agree jointly, since it feeds every floor, and we can bring one quote covering the sump plus all the floor tanks together.
“How do you work around the plot’s water schedule?” We isolate and drain one tank at a time around the DJB fill and pump timing noted at the survey, so the floors above keep supply. We usually clean the sump first, refill it, then take each floor’s rooftop tank in turn, finishing a Kailash Colony plot in a day and confirming supply is normal.
“Do you offer an AMC for Kailash Colony plots?” Yes. The AMC covers four visits a year for the plot’s sump and all rooftop tanks at 20 to 25 percent off the per-visit rate. Because the floors share one sump, quarterly cleaning protects all of them, and each visit ends the builder-floor owners can keep on file.
