We clean society overhead tanks, underground sumps and individual flat tanks across Dwarka Sector 17's group-housing societies and DDA pockets, same day where possible. Starting ₹699.
Sector 17 is a quieter residential sector with a steady mix of CGHS group-housing societies, a couple of DDA flat pockets and builder floors on the plotted stretches. The societies here are mostly mid-rise, so overhead tanks tend toward the 5,000-8,000L range paired with a moderate underground sump. DJB piped supply is the mainstay and reasonably clean, but several societies keep a borewell for garden and common-area use that occasionally cross-feeds the domestic tanks, and that is where we find the heavier scaling. The builder floors on the plotted lanes have per-floor tanks that scale in the sun. Overall Sector 17 leans toward planned, RWA-organised society cleaning with a regular stream of individual builder-floor and DDA-flat requests alongside.
We tend to get Sector 17 society bookings as scheduled weekend jobs so more residents are around to unlock terrace access and sump chambers. For the builder floors we keep weekday same-day slots since those are usually single-home calls.
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.
Sector 17 RWAs mostly book us as a planned weekend job so residents can unlock terrace and sump access and watch the work if they want. We drain the 5,000-8,000L overhead tank, scrub and sanitise it, and open the underground sump to clear the settled sediment. A shared overhead tank alone is ₹2,500-3,000; because the sumps here quietly collect grit from the cross-feeding borewell, the combined overhead-plus-sump clean at ₹4,500-6,000 is the more sensible choice and the one we usually recommend. Split across the block the per-flat cost lands around ₹120-160, and we leave a dated service slip the RWA can file for its records.
Away from the societies, Sector 17's builder floors and DDA pockets have individual per-floor or per-flat tanks that homeowners book directly, usually when the water starts tasting flat or a new tenant is moving in. A single builder-floor or DDA-flat tank is ₹699-1,499 depending on size and buildup. Where a borewell has been cross-feeding a home's tank we add a descaling scrub without treating it as a separate trip, keeping it within that band. If several floors of one builder building book together, we run them consecutively and hold the price toward the lower end, which is the cheapest way to get a whole building done.
“Why do you recommend the combo clean in Sector 17?” Society sumps here pick up grit from borewells used for common areas that sometimes cross-feed the domestic line. The combined overhead-plus-sump clean at ₹4,500-6,000 clears both.
“Can I watch the cleaning being done?” Yes, and many Sector 17 residents do — we book weekend slots partly so people are around. We also leave a dated service slip for the RWA.
“Is descaling charged separately on a builder floor?” No. Where a borewell has been cross-feeding the tank we include the descaling scrub in the same visit, keeping it within the ₹699-1,499 band.
