Signs Your Water Tank Needs Cleaning

We clean the overhead tanks and sumps of Rohini Sector 3's DDA MIG flats, group-housing societies and builder floors — same day where possible. Starting ₹699.
Sector 3 is dominated by well-laid-out DDA MIG flat blocks and a good number of registered group-housing societies, so shared overhead tanks feeding whole staircases are the norm rather than tiny individual tanks. The societies here often run a society borewell as backup to the DJB line, and that borewell water carries more grit and iron, which speeds up sediment build-up in the underground sumps. We see a lot of 3,000-5,000L society tanks that serve dozens of flats and really need two cleans a year to stay clear. Moderate hard-water scaling shows up on the walls but it is the borewell sediment that dominates here. The builder floors on the plotted edges have their own smaller poly tanks.
Sector 3 is one of our most RWA-organised sectors, so we often schedule a whole society's tanks across a single day with the secretary coordinating access to each block. That planning lets us give the society a better per-tank rate and a fixed annual slot.
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.
The classic Sector 3 job is a group-housing society running DJB water topped up by a borewell, where the underground sump has filled with iron-grit sediment and the overhead tanks need clearing too. We clean the big 3,000-5,000L shared overhead tanks at ₹2,500-3,000 each, and the underground sump at ₹1,500-2,500, or bundle a combined overhead-plus-sump clean at ₹4,500-6,000. Because the borewell backup adds grit, we always recommend the society do the sump at the same time. The RWA usually recovers the cost across flats, which keeps each household's share low.
Sector 3 societies get the most value from an annual RWA contract that covers every block tank and the shared sump on a fixed twice-a-year schedule. It removes the yearly scramble to find a cleaner before summer and gives a guaranteed rate per tank, typically landing each flat's yearly share around ₹250-350 for two cleans. Individual MIG flat owners who want their own tank done separately can still book from ₹699. Move-in cleaning for a resale flat, where the buyer wants the shared line flushed and the tank sanitised before shifting, is a common one-off we handle same day.
“Our society uses a borewell too — does that change anything?” It does — borewell water adds iron grit, so sumps fill faster. We always suggest cleaning the sump (₹1,500-2,500) with the overhead tanks, or a combined clean at ₹4,500-6,000.
“What does an annual society contract cost per flat?” For twice-a-year cleaning of the block tanks and shared sump, each flat's yearly share typically works out around ₹250-350. The RWA books one fixed schedule and we handle every block.
“Can one flat owner book separately from the society?” Yes. If you want just your own tank done, an individual clean starts at ₹699 and we can usually fit it in the same day.
