Overhead (rooftop) tank cleaning in Dwarka Sector 2 for DDA MIG, SFS blocks and 1990s CGHS towers. From ₹699.
Sector 2 is a quiet residential sector of DDA MIG and SFS flats interleaved with a number of cooperative group housing societies built in the late 1990s. The DDA blocks run rooftop overhead tanks, while the CGHS towers pair large overhead tanks with underground sumps. In both cases the overhead tank is the last stop before the tap, with no filter after it, so anything settled inside reaches your kitchen directly. A season of standing water leaves scale and grit across the tank floor.
Water in Sector 2 is the usual Dwarka mix of Sonia Vihar DJB pipeline supply and DDA borewells, leaving it hard and mineral-heavy. That is why the 1990s CGHS terraces and DDA rooftops here need more than a quick rinse. Whether you have a single flat tank or a whole society terrace, our water tank cleaning in Dwarka Sector 2 service covers overhead and underground tanks alike. Every job closes with before/after photos and a dated certificate.
The DDA borewell portion of Sector 2’s supply is hard and high in dissolved solids, so each fill deposits minerals that harden into chalky scale inside the rooftop tank. The older 1990s CGHS overhead tanks, having run for decades, often carry a stubborn built-up layer along the walls and base. Rooftop dust settling through vents and loose lids adds a gritty sludge on top of that. Together they cloud the water and can breed bacteria in the standing layer.
We handle it methodically: drain the tank, scoop the sludge by hand, then jet wash at high pressure to shear off the bonded scale that a rinse never touches. A hand-scrub of every wall and corner follows, then a food-grade disinfectant safe for potable water. We refill and provide before/after photos and a dated certificate. For the CGHS towers we can coordinate the overhead tank and the sump together so the whole line is clean end to end.
No travel charge anywhere in Dwarka Sector 2. 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 2 — and there’s no travel charge to any of them:
“What is the difference between cleaning a DDA block tank and a CGHS society terrace tank in Sector 2?” A DDA MIG or SFS block usually has one or two smaller rooftop overhead tanks that we can finish in under two hours. A 1990s CGHS society terrace in Sector 2 often has much larger overhead tanks plus an underground sump, so it needs a bigger crew and more time. We price the society jobs by total capacity, still starting from ₹699 for a standard flat tank. Both get the same drain, jet wash, disinfect and certificate.
“How long does a rooftop tank clean take on a Sector 2 SFS block?” For a single SFS or MIG rooftop tank, expect roughly ninety minutes from drain to refill. Larger or heavily scaled tanks on the older blocks can take a little longer because the bonded scale needs extra jet washing. We work around your water-supply timing so the tank refills soon after. You get before/after photos before we leave.
“Is the disinfectant you use safe for drinking water?” Yes, we use a food-grade disinfectant approved for potable water tanks, and we rinse thoroughly before refilling. It removes bacteria and the biofilm that forms in standing borewell water without leaving any harmful residue. This matters because the rooftop tank is the last stop before your tap with no filter after it. Your water is safe to use once the tank refills.
“Can you clean tanks for a whole 1990s CGHS society in one visit?” Yes, for the late-1990s CGHS societies in Sector 2 we can bring a crew sized to do all overhead tanks and the underground sump in a single scheduled visit. We coordinate with the RWA or maintenance office to minimise supply disruption. Each tank gets its own before/after photos and the society receives a consolidated dated certificate. Bulk terraces are quoted by total capacity.
“Why is there gritty sludge at the bottom of my overhead tank?” That grit is settled borewell sediment plus rooftop dust that has drifted in through the lid and vents over the season. Because it collects at the tank floor right above the outlet, it can reach your taps whenever the level drops. Scooping and jet washing that layer out is the core of our job. After cleaning, the base stays clear until the next borewell cycle rebuilds it.
