Home › Water Tank Cleaning › Overhead Tank Cleaning › Greater Kailash
In Greater Kailash, each builder floor usually keeps its own overhead tank on a shared rooftop — the last stop before that floor’s taps. KaamGenie cleans the rooftop tanks of GK-1 and GK-2, floor by floor. From ₹699.
Greater Kailash has largely gone from single kothis to four-floor builder floors across GK-1’s M, N, S, W and E blocks and all of GK-2, with the busy M-block market in the middle. Supply is DJB with borewell backup, and a shared underground sump per plot pumps up to the roof. What is distinctive here is that each builder floor commonly has its own overhead tank clustered on the shared terrace, so one rooftop can carry three or four separate tanks feeding different families.
KaamGenie cleans these per-floor rooftop tanks individually or all together — we drain each, clear the sludge, jet-wash the scale, scrub the corners and inlets by hand, then disinfect with a food-grade wash and send each owner dated before-and-after photos. Doing the whole terrace in one visit is simplest and cheapest for the building. This page belongs to our water tank cleaning in Greater Kailash service and focuses on the overhead (rooftop) tanks.
In a converted GK builder floor, the individual overhead tanks are usually compact plastic units sized for one family, so they fill and empty quickly and never hold still long enough to fully settle — which keeps fine sediment circulating into the taps. They also sit on an exposed shared terrace, catching soot and dust from the busy roads and the M-block market nearby. Small, hard-working and open to the air, these tanks build a film and a grit layer within months.
Because each floor owns its own tank, responsibility for cleaning is split and often nobody takes it on, so tanks go years untouched while the family below assumes the water is fine. The borewell backup adds hard-water scale during shortages, and the neighbouring tanks on the same roof can age at different rates, meaning one dirty tank sits beside a clean one. Cleaning the whole cluster together on one visit keeps every floor’s supply even and fresh.
No travel charge anywhere in Greater Kailash. The final price is confirmed on the call before we come — it depends only on tank size and access.

We reach every pocket of Greater Kailash — and there’s no travel charge to any of them:
“Do you clean overhead tanks on the builder floors in M Block, GK-1?” Yes. M Block is a regular stop for us, along with the N, S, W and E blocks and all of GK-2. Because each builder floor here usually has its own rooftop tank, we can clean just yours or the whole terrace cluster in one go. Tell us how many tanks are on the roof and we will schedule accordingly.
“How much to clean one builder-floor overhead tank in GK?” A single builder-floor tank up to 500 litres is ₹699, and a standard 1,000-litre unit is ₹899. Larger 1,001 to 2,000-litre tanks are ₹1,299 to ₹1,499. When several floors get their separate rooftop tanks cleaned together on one visit, we apply a bulk discount, so doing the whole GK terrace at once works out cheaper per tank.
“Can you clean my GK rooftop tank the same day?” Often, yes. Call the KaamGenie team on 95603 66362 and, if the schedule permits, we will reach your Greater Kailash block the same day. A single compact builder-floor tank takes about ninety minutes, so a morning booking is cleaned, disinfected and refilled well before the evening in most cases.
“Why does my GK builder-floor tank get dirty so quickly?” It is small and works hard, filling and emptying for one family several times a day, so grit never fully settles out and keeps reaching the taps. The shared terrace is exposed to road soot and market dust that gets in past the lid, and borewell top-ups add scale. A compact rooftop tank like this shows sediment and film within a few months.
“The four floors on our GK plot each have a tank — can you do them together?” Yes, and that is the sensible way here. We clean each floor’s rooftop tank in turn on a single visit, isolating and draining one at a time, then jet-washing, scrubbing and disinfecting each. Every owner gets their own before-and-after photos, and doing all the tanks together earns a bulk discount and keeps the whole building’s water fresh at once.
