Whole-building tank cleaning for Subhash Nagar’s builder floors — the common tank that four floor-owners each assume someone else maintains, cleaned along with every per-floor tank in one visit with a certificate per owner. From ₹1,500 per tank.
Subhash Nagar is the quiet plotted colony between Tilak Nagar and Rajouri’s edge, and its lanes have been comprehensively rebuilt: 4-storey builder floors with stilt parking, sold floor by floor to young families. The standard setup is one 1000L tank per floor plus a common tank — and on DJB’s timed supply the tanks cycle daily. The per-floor tanks belong to someone; the common tank belongs to everyone, which in practice means it goes years uncleaned while four owners each assume another has handled it.
KaamGenie’s Subhash Nagar service is the whole-building booking that closes that gap: all four floor tanks plus the common tank in one visit, cost split by a formula the owners agree once — usually per-floor tanks to their owners and the common tank four ways. Every tank is drained, de-sludged, jetted, scrubbed and disinfected food-grade, and every owner receives a certificate for their tank plus a shared one for the common tank. For a single floor’s tank, see water tank cleaning in Subhash Nagar.
A builder floor has no RWA, no maintenance agency, no caretaker — just four households connected by a stairwell and a shared tank none of them chose. The per-floor tanks get attention because each family sees the result in its own taps; the common tank, which typically feeds the stilt-level washing points, the backup line and sometimes the ground-floor unit, sits unclaimed. Four years after possession it has never been opened, and its sediment is the building’s oldest resident.
The one-visit format fixes the coordination problem permanently: a single WhatsApp agreement among the owners, one crew day, five tanks done, five certificates issued, and a ₹1,500-per-tank rate with the multi-tank discount that makes the split smaller than any owner expects. Most buildings then standing-order the repeat — every four to five months on DJB timed supply — so the common tank never again depends on somebody remembering. Neighbouring buildings aligning dates extend the discount further down the lane.
No travel charge anywhere in Subhash Nagar. The final price is confirmed on the call before we come — it depends only on tank size and access.

“Our four owners can never agree on maintenance — how do others manage this?” By making it one small decision instead of many: a single yes to a whole-building visit, with the split fixed in advance — each owner pays for their floor tank, the common tank divides four ways. After the first round the repeat is a calendar entry, not a negotiation. We handle scheduling with one coordinating owner.
“What does the whole building cost?” Five tanks — four per-floor plus the common — at ₹1,500 each, less the multi-tank discount for doing them in one visit. Per owner that lands around the cost of a single standalone clean, for a building where every tank including the forgotten common one is done and certified.
“Does the common tank really matter if each floor has its own tank?” Yes — in most Subhash Nagar builder floors the common tank feeds the backup line that tops up the floor tanks when DJB timing is missed, so its water ends up in every floor’s tank eventually. A fouled common tank quietly reseeds four clean ones, which is why we insist on including it.
“We only moved in last year — does a new building need this already?” Sooner than you would think. Builders rarely clean tanks after construction, so a two-year-old building often carries cement fines and construction debris under its first layers of DJB silt. The first clean is effectively the commissioning clean the building never had; after it, the normal cycle applies.
“Can you do an urgent clean the same day?” Usually, for one or two tanks booked before 10 AM — Subhash Nagar is squarely on our Tilak Nagar-Rajouri route. A full five-tank building visit is better set a day ahead so all four owners can run their tanks low for the drain.
