Overhead and underground tank on a kothi near the Nirankari Sarovar, group-housing tank off Nirankari Colony main road, whole-building booking near GTB Nagar, we clean them all. Starting from Rs 699.
Nirankari Colony is a planned pocket near GTB Nagar and the Nirankari Sarovar, laid out with independent kothis and group-housing blocks rather than the dense builder floors of the outer belt. Most homes run on DJB supply of moderate hardness, so the tanks collect a steady sediment on the floor with only light scale on the walls. The common setup here is an underground sump feeding an overhead tank, and the sump quietly gathers grit that never gets seen or cleaned. Water sitting in the two-tank chain lets sediment settle in both, and the overhead tank clouds up if the sump underneath is left dirty.
Our crew handles the overhead and the underground sump together in one visit, draining and scrubbing both so the whole chain runs clean. We work the wider colony roads easily and reach the kothi rooftops and sump chambers without fuss.
For a standard 1000-litre overhead tank, the whole job takes about 90 minutes from when we ring your doorbell to when we’re packing up. Underground sumps take a bit longer — usually 2 to 2.5 hours depending on how much sludge has built up.
You don’t need to provide anything. We bring our own water for the rinse, our own electricity backup if needed, vacuums, jet pumps, food-grade disinfectant, gloves, the works. We’ll show you photos of the tank before and after on WhatsApp once we’re done.
The typical Nirankari Colony home has an underground sump that fills from the DJB line and pumps up to an overhead tank, and both need cleaning because the sump quietly collects grit that gets pumped upward. A combined overhead-plus-sump clean runs Rs 2,000 to 2,800 depending on the sump size, and the crew drains both, scrubs the walls and floor, flushes the sediment, and finishes with a disinfectant wash. Cleaning only the overhead tank leaves the sump feeding grit back up, so we always suggest doing the pair together. A single overhead tank on its own starts at Rs 699.
Nirankari Colony mixes independent kothis with group-housing blocks, and for a block with several tanks a whole-building booking runs Rs 2,400 to 3,000 for the full set in one visit, cheaper than separate call-outs. The moderate DJB hardness means twice a year is usually enough here, unlike the harder borewell belts. One resident or the RWA can book for a block, and we coordinate access unit by unit. Payment is on the spot by cash, UPI or card.
"We have an underground sump and an overhead tank. Do you clean both?" Yes, and we suggest doing both together. The sump quietly collects grit that gets pumped up to the overhead tank, so cleaning only the overhead one leaves it clouding up again. A combined overhead-plus-sump clean runs Rs 2,000 to 2,800 depending on the sump size, done in one visit.
"Our supply is DJB and fairly clean. How often should we clean?" With the moderate DJB hardness in Nirankari Colony, twice a year is usually enough. If your sump has not been opened in a long while we suggest starting with a combined clean and then keeping to a six-month schedule.
"Can the group-housing block book together?" Yes, and it is the cheaper way. A whole-building multi-tank visit is Rs 2,400 to 3,000 done in one trip, with a single invoice. One resident or the RWA can book for the whole block.
