Builder Floor Tank Cleaning

Around the Lal Quarter market, Krishna Nagar's old kothis have been rebuilt into three-family floors that still share the one overhead tank the original house was built with. This service cleans that shared tank and records it for the family that owns the building. From ₹1,500 per tank.
Krishna Nagar is one of East Delhi's settled, prosperous colonies, its lanes centred on the busy Lal Quarter market and lined with independent kothis and their newer builder-floor rebuilds. Where a single house has become three or four floors, the families living in them usually share the rooftop overhead tank, and the larger kothis add an underground sump feeding it. Supply is mainly DJB, pumped up reliably, so the water is softer than the borewell belts further north but far from sediment-free. Being owner-occupied and long established, these buildings have tanks that are decades old and often original to the house. That age is exactly the issue: an RCC tank twenty years in service holds a hard scale layer a rinse will never shift.
KaamGenie cleans the shared overhead tank, and the sump where a kothi has one, in a single visit fixed with the family that owns the floors. We empty the tank, break down the old scale, hand-scrub every wall and corner, sanitise to hygienic standard and provide a dated photo record for the household. If one floor's owner wants only their own tank done, water tank cleaning in Krishna Nagar covers that. This page is for the shared, whole-building tank several families use.
A tank that has served a Krishna Nagar kothi since the house was first built has had twenty or more years of DJB water passing through it, and even relatively soft supply lays down a slow mineral scale over that span. Now that three or four floors draw on the same tank, it works harder than it was designed to, and the old walls give scale a rough surface to cling to. The build-up is not the loose silt of a borewell belt but a bonded crust that has set over years. It takes mechanical scrubbing, not chemicals alone, to bring the wall back.
Under that scale sits the biofilm that turns a settled tank's water musty, and in a shared house the whole family notices it at once, from the ground-floor kitchen to the top-floor bath. Flakes of loosened scale also travel into the geysers and RO units the floors have installed, fouling them early. For an owner who has kept the property well otherwise, the tank is the one part never opened. A yearly clean keeps a heritage kothi's shared supply as sound as the rest of the house.
No travel charge anywhere in Krishna Nagar. The final price is confirmed on the call before we come — it depends only on tank size and access.

“Our overhead tank is original to the house and has never been opened. Can it be cleaned properly?” Yes. An original RCC or Sintex tank two decades old holds a bonded scale that we take off by hand-scrubbing, not a quick rinse. We plan the extra time at the survey, disinfect hygienic afterwards, and show you the before-and-after so you can judge how far gone it was.
“The kothi has a sump under the driveway too. Do you clean both?” We do, and on a bigger Krishna Nagar house we recommend it. The sump collects its own settled load and feeds the overhead, so cleaning only the roof tank leaves the source below untouched. We do the sump with confined-space care and the overhead in the same visit.
“What is the cost, and is there a yearly rate for a family house like ours?” A rooftop overhead tank is ₹1,500 to ₹2,000 by size, and a sump is quoted alongside it. Doing the overhead and the sump together on one visit earns a combined-job discount, and an annual maintenance visit for the household comes at a reduced rate.
“We are three floors of one family sharing the tank. Do we book once for all of us?” Yes. One booking covers the shared overhead tank for the whole building, whichever floor makes the call. We clean it once for everyone and leave a single dated record the family can keep for the house.
“Do you offer a yearly maintenance visit for a settled colony house here?” Yes. An annual visit covers the overhead tank and the sump for the household at a lower rate than a one-off call. On the reliable DJB supply here a once-a-year clean is usually enough to keep a decades-old tank clear.
