Society and RWA tank cleaning in Mansarovar Garden — the whole sump-to-rooftop system serviced together, because the sump under the stilt parking is the tank owners here forget they own. From ₹1,500 per tank.
Mansarovar Garden is an established plotted colony on the Kirti Nagar side of Ring Road with a strong Punjabi trading community — original double-storeys alongside premium rebuilds with basements, lifts and proper water systems. Those systems are the point: more than its neighbours, this colony runs sump-plus-rooftop setups, with the sump tucked under stilt parking. Owners see the roof tank every time they dry clothes; the sump can go unopened for years while they assume the visible tank is the whole story.
KaamGenie’s Mansarovar Garden service is built around that blind spot: every whole-house booking starts at the sump — opened, drained, scrubbed with confined-space precautions — then follows the water up through the booster to the rooftop tanks, so the entire chain is clean on the same day. RWA-coordinated service days cover multiple houses in sequence with a consolidated register for the association. For a single tank, see water tank cleaning in Mansarovar Garden; this page is for whole-system and colony-coordinated work.
The sump is the first tank the mains touch, so it takes the full sediment load — silt, rust, whatever the line delivers — and holds it in the dark, at ground temperature, where biofilm grows happily. Every time the booster runs, a measure of that settles into the rooftop tanks. Clean the roof tanks alone and they are re-seeded within weeks; the owners who complain that ‘cleaning never lasts’ are almost always the ones whose sump has not been opened since the house was built.
A full-chain clean every six months is the schedule that actually holds here, and doing it as one visit is cheaper and less disruptive than piecemeal jobs — one drain-down, one crew, one afternoon. The trading families of this colony respond to evidence, so we provide it: photos of the sump before and after, the sludge we removed, and a dated certificate per tank. Several lanes have moved to informal service days — four or five houses, one date — which brings block pricing without needing a formal society structure.
No travel charge anywhere in Mansarovar Garden. The final price is confirmed on the call before we come — it depends only on tank size and access.

“We have never opened our sump. What should we expect?” Honestly: a few inches of dark sludge, possibly a biofilm ring, occasionally worse — and none of it is unusual for a sump unopened for years. We photograph it before touching anything, remove and bag the sludge, scrub and disinfect, and show you the after photos. Most owners move to a six-monthly cycle once they have seen the first set.
“Is sump cleaning safe? It is a confined underground space.” Yes, with the right procedure — which we follow strictly: the sump is fully drained and ventilated before entry, a second crew member stays topside throughout, and electrical connections to the booster are isolated first. This is routine for our teams and non-negotiable in every Mansarovar Garden basement and stilt sump.
“What does the full house system cost?” Sump plus rooftop tanks books from ₹1,500 per tank, with a whole-system rate at survey — a typical house is sump plus one or two roof tanks. Oversized basement sumps are quoted by volume upfront. Lane service days of four or more houses bring the per-house cost down further.
“How long is the house without water?” Around half a day. We schedule after the morning fill, work sump-first then the roof tanks, and the booster refills the system by evening. The house keeps a reserve if you ask us to leave one roof tank for last. Same-day visits are often possible — call 95603 66362 before 10 AM.
“Can our lane organise a joint service day without a formal RWA?” Yes — several Mansarovar Garden lanes already run this way. One owner fixes a date, neighbours confirm, and we sequence the houses across the day with block pricing. Each house gets its own certificate set; the lane gets the convenience of one date to remember instead of five.
