How Long Does Tank Cleaning Take?

We handle overhead tanks, sumps and combo jobs for Dwarka Sector 12's CGHS societies, DDA flats and the shops around the sector market, same day where possible. Starting ₹699.
Sector 12 mixes tall CGHS group-housing societies with a busy sector market and one of the better-connected Metro exits, so tanks here range from 5,000-10,000L society overheads down to small commercial storage drums behind the shops. The DJB piped supply is fairly reliable in this pocket, but many societies still keep a borewell running for the market-facing blocks, and that borewell water leaves the heavier mineral scaling on tank walls. We commonly find a hard whitish scale ring at the fill line and a settled sediment layer that thickens through the dry months. The commercial units near the market often neglect their small tanks entirely until the water starts smelling, so those are usually heavier single cleans.
Booking rhythm here splits between planned RWA slots for the residential blocks and last-minute calls from the market shops. We keep an early crew for the market side so shops can have tanks cleaned before opening, and a mid-morning crew for the society blocks.
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.
Several Sector 12 societies have moved to an annual cleaning contract because their shared overhead tanks — usually 8,000-10,000L feeding a full stack — build up scale fast on borewell backup water. Under a contract we clean each block's overhead tank and sump on a fixed schedule, so the RWA does not have to chase a booking every time the supply looks cloudy. A one-off shared overhead tank clean is ₹2,500-3,000, and a combined overhead-plus-sump job is ₹4,500-6,000; on an annual contract across multiple blocks the per-flat share typically settles near ₹120-150 per flat per clean. RWAs like that they get a dated service record they can show at the AGM.
The shops and eateries around the Sector 12 market run small 300-800L storage tanks that get neglected until the water turns, and food outlets in particular need these done properly. We drain, scrub and sanitise these before opening hours so there is no disruption to trade. A small commercial tank clean is usually ₹1,500-2,500 depending on how heavy the buildup is and whether it is a rooftop tank or a ground drum. If a shop wants a standing quarterly visit we set that up so the tank never gets to the point where it affects the water. For a plain individual residential tank above a shop the price drops to the ₹699-1,499 band.
“Do you clean tanks for shops in the Sector 12 market?” Yes. We do the small 300-800L commercial tanks behind the market shops before opening hours, usually ₹1,500-2,500 depending on buildup. Quarterly visits are available too.
“Why does my Sector 12 society tank scale so quickly?” Blocks running on borewell backup pick up more mineral content, which leaves a hard scale ring. An annual clean keeps it from thickening into the supply.
“What does an annual RWA contract cost per flat?” On a multi-block contract the per-flat share usually lands around ₹120-150 per clean, versus a one-off shared tank at ₹2,500-3,000 for the block.
