Overhead (rooftop) tank cleaning in Dwarka Sector 1 for the DDA LIG and Janta blocks near Dwarka Mor. From ₹699.
Sector 1 is one of Dwarka’s earliest-settled pockets, sitting close to Dwarka Mor and Dashrathpuri, and it is dominated by DDA LIG and Janta flats with a scatter of resale builder floors. Almost every home here draws from a rooftop overhead tank perched on the low-rise DDA blocks. Because that Sintex or RCC tank is the last stop before the tap — there is no filter after it — whatever settles inside goes straight into your drinking and cooking water. On these older blocks the borewell sediment and chalky scale collect fast at the tank base.
The piped supply here is the standard Dwarka 50-50 of Sonia Vihar DJB water and DDA borewells, so it runs hard and high-TDS. That mineral load is exactly why a rooftop tank in Sector 1 needs a proper drain-and-scrub, not just a rinse. If you also manage a ground sump or want the full block covered, our wider water tank cleaning in Dwarka Sector 1 service handles both overhead and underground tanks. We finish every job with before/after photos and a dated certificate.
The DDA borewell half of Sector 1’s supply is hard and high-TDS, and every fill leaves dissolved minerals behind as the water sits in the rooftop tank. Over a few weeks that hardens into a chalky white scale on the walls and floor, while grit and borewell sediment build a gritty sludge layer at the bottom. On the exposed rooftops of these old DDA blocks, dust and airborne dirt add to the load through the tank lid and vents. Left alone, that mix taints the taste of your water and can clog the outlet.
Our process is built for exactly this. We drain the tank fully, scoop out the settled sludge by hand, then high-pressure jet wash every surface to break the bonded scale. After that comes a thorough hand-scrub of the walls, floor and corners, followed by a food-grade disinfectant wipe-down that is safe for drinking water. We rinse, refill and hand you before/after photos plus a dated certificate — usually done in about ninety minutes for a single rooftop tank.
No travel charge anywhere in Dwarka Sector 1. The final price is confirmed on the call before we come — it depends only on tank size and access.

We reach every pocket of Dwarka Sector 1 — and there’s no travel charge to any of them:
“How much does it cost to clean a single 1000L rooftop tank in a Sector 1 DDA flat?” For a standard 1000L rooftop overhead tank on a DDA LIG or Janta block, our service starts from ₹699. The exact price depends on tank size and how much borewell sludge has built up, but a single flat tank near Dwarka Mor almost always falls in the base band. We confirm the rate before we start, with no surprise add-ons. The dated certificate and before/after photos are included.
“Do you clean overhead tanks on the old low-rise DDA blocks near Dashrathpuri?” Yes, the low-rise DDA LIG and Janta blocks around Dashrathpuri and Dwarka Mor are exactly what we handle most in Sector 1. Their rooftop Sintex and RCC tanks are easy to access and we carry our own pump, jet washer and food-grade disinfectant. Because these blocks are older, the scale is often thicker, so we budget extra scrubbing time. You still get the same dated certificate at the end.
“Why does my rooftop tank water taste chalky even though it looks clear?” That chalky taste comes from the high-TDS DDA borewell mineral content dissolving into the standing water in your rooftop tank. Since the overhead tank is the last stop before your tap with no filter after it, those minerals reach you directly. A full drain, jet wash and disinfectant clean strips the scale layer that keeps feeding that taste. Most Sector 1 homes notice a clear difference the same day.
“How often should a Sector 1 overhead tank be cleaned?” For the hard, borewell-heavy water in Sector 1 we recommend cleaning your rooftop tank every three to four months. The borewell sediment and rooftop dust build up faster here than in areas on pure DJB supply. If your building is right next to a dusty stretch of Dwarka Mor, err toward the shorter end. We can set a reminder so you never miss a cycle.
“Can you clean the tank without wasting much water?” We drain only what is needed and time the job so refilling happens right after, keeping wastage low. For a typical 1000L rooftop tank the drained water is mostly the sludge-laden bottom layer, which you would not want to keep anyway. We can also schedule around your DDA supply timing so the tank refills naturally. The tank is back in service the same day.
