How Long Does Tank Cleaning Take?

Johri Farm — the apartment pocket on the Noor Nagar and Jamia fringe where old farm plots became five- and six-storey flats over stilt parking, each running a sump below and a bank of tanks above. We clean the whole system, sump ₹1,499, tanks from ₹699.
Johri Farm’s buildings follow one template: private five- or six-storey flats over stilt parking, an underground sump in or beside the stilt floor, and a bank of rooftop tanks the sump pump feeds. On borewell water, that two-stage storage doubles the sediment problem — the sump collects the heavy silt and iron particles first, then the pump lifts water that scales and stains the roof tanks anyway. Clean one stage and the other reloads it; the system only stays clean when both are done together.
Ownership here is by-the-flat, with informal building committees rather than registered RWAs, so common-area spending needs a nudge — usually one motivated owner collecting ₹300–500 per flat. Sumps in the stilt floors take in parking dust and the occasional monsoon backflow through poorly sealed covers, and we’ve pumped out sump sludge in this pocket that clearly dated to the building’s construction. Once a building does its first full clean, the annual repeat books itself.
For a standard 1000-litre overhead tank, the whole job takes about 90 minutes from doorbell to pack-up. Underground sumps take longer — usually 2 to 2.5 hours depending on sludge. You don’t need to provide anything: we bring our own water for the rinse, vacuums, jet pumps, food-grade disinfectant and gloves, and send before/after photos on WhatsApp.
Every Johri Farm building stores its water twice, so sediment gets two places to live. Our building-wide clean does the full chain in one scheduled visit: sump dewatered, sludge pumped out and walls scrubbed for ₹1,499; every rooftop tank drained, descaled and disinfected at ₹699–899 each depending on size; and the transfer pump’s foot valve checked while the sump is open. A typical five-storey building takes half a day and comes back online tank by tank, not all at once.
The hardest part of a Johri Farm clean isn’t the sludge — it’s the WhatsApp group. We make the coordination easy: one owner gets a written per-building quote to circulate, we split the total per flat on request so everyone sees their ₹300–500 share plainly, and payment can come from multiple flats separately. On the day, we need one keyholder for the stilt floor and roof; everyone else just gets the before-and-after photos and cleaner water.
“What does a full building clean cost in Johri Farm?” For a typical building — one sump plus three or four roof tanks — expect ₹1,499 for the sump and ₹699–899 per tank, so roughly ₹3,600–5,100 total. Split across ten or twelve flats that’s a few hundred rupees each. We give a written quote your building group can circulate.
“How long is the water off during a building-wide clean?” Flats are never all dry at once. We clean the roof tanks in sequence so supply rotates, and the sump work happens while the roof tanks still hold water. Most residents notice a slow tap for a few hours, nothing more.
“Our sump is under the stilt parking and hasn’t been opened in years. Is that a problem?” It’s exactly why to book. Stilt-floor sumps collect parking dust and years of borewell silt; we dewater completely, pump out the sludge, scrub and disinfect, and photograph the interior before and after. If the cover seal is letting monsoon runoff in, we’ll show you that too.
