Hard Water Tank Cleaning in Delhi

We clean overhead tanks and sumps for Rohini Sector 9's DDA MIG flats, group-housing societies and builder floors — same day where possible. Starting ₹699.
Sector 9 is a settled residential sector built around DDA MIG flat blocks and several registered group-housing societies, so shared overhead tanks serving whole staircases and society sumps are the mainstay of our work here. The societies are well organised with active RWAs, and many already run a maintenance calendar, which makes tank cleaning a scheduled line item rather than an afterthought. DJB piped supply is moderately hard, giving the usual wall scaling, while the society sumps collect sediment from the storage buffer they keep for low-pressure hours. Builder floors on the plotted fringe carry their own smaller poly tanks. The MIG blocks' tanks are mostly 2,000-3,000L RCC or poly units per staircase.
Sector 9's organised RWAs mean we do a lot of pre-planned society rounds, cleaning several block tanks in a coordinated morning with the secretary arranging access. Individual MIG-flat owners and builder-floor tenants fill our same-day slots between the scheduled society jobs.
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.
A typical Sector 9 job is a DDA MIG staircase whose 2,000-3,000L shared overhead tank is due on the society's maintenance calendar, cleaned before it turns cloudy in summer. We drain, de-silt, scrub off the hard-water scaling, disinfect and refill, all in a morning. The shared block tank band is ₹2,500-3,000, split across the staircase's flats by the RWA at roughly ₹150-180 each, with a ₹300-500 descaling add-on where valves have furred. Because the RWAs here plan ahead, we often lock the whole society's blocks into one scheduled visit for a better per-tank rate.
Sector 9's group-housing societies keep an underground storage sump for low-pressure hours, and that buffer collects sediment that needs clearing once or twice a year. A sump clean is ₹1,500-2,500, or a combined overhead-plus-sump job ₹4,500-6,000. Most societies here take an annual RWA contract covering every block tank and the shared sump on a fixed twice-a-year schedule, which suits their maintenance calendar and typically lands each flat's yearly share around ₹250-350. Individual flat and builder-floor owners can still book their own tank from ₹699, same day where a slot is free, including move-in cleans for resale flats.
“Can you fit into our society's maintenance calendar?” Yes — Sector 9's RWAs plan ahead, so we lock the whole society's block tanks into one scheduled visit. Booking all blocks together earns a better per-tank rate.
“How much is our society sump to clean?” A sump on its own is ₹1,500-2,500, or a combined overhead-plus-sump clean is ₹4,500-6,000. The storage sump collects sediment, so once or twice a year is right.
“What will each flat pay under an annual contract?” For twice-a-year cleaning of block tanks and the shared sump, each flat's yearly share is typically around ₹250-350, and the RWA books one fixed schedule.
