Your rooftop overhead tank in Neb Sarai is the last stop before every tap, and borewell-heavy supply leaves scale behind. KaamGenie cleans overhead tanks across the village houses, builder floors and apartment blocks between Saket and Sainik Farms. From ₹699.
Neb Sarai is a mixed urban village and colony belt between Saket, Khanpur and Sainik Farms, with village houses, builder floors and small apartment blocks. Supply combines a limited DJB pipeline with private borewells, so the water is generally hard with elevated TDS. In a rooftop tank that borewell-heavy mix leaves a chalky scale on the walls and a fine sediment on the floor, fed up from an underground sump in most homes.
KaamGenie cleans these rooftop tanks thoroughly — drain, scoop the sludge, high-pressure jet-wash the scale, hand-scrub the corners, then a anti-bacterial disinfectant wash, finished with before-and-after photos on WhatsApp. This is our dedicated page for water tank cleaning in Neb Sarai, focused specifically on the overhead (rooftop) tanks that feed your taps.
The pipeline reaches Neb Sarai only partly, so most buildings top up heavily from borewells drawing hard, high-TDS water. Every fill leaves minerals on the rooftop tank walls, and over months that becomes a scale you can flake off. With the overhead tank feeding your taps directly and no filter after it, that scale and the sediment below flow through to the kitchen.
The area runs the full range from small village houses to newer apartment blocks, and the apartment blocks often share a terrace tank bank that all flats draw from. Whether it is a single house tank or a shared bank, the borewell-heavy supply means sediment and scale accumulate steadily, so twice a year is the right rhythm for most buildings here.
No travel charge anywhere in Neb Sarai. The final price is confirmed on the call before we come — it depends only on tank size and access.

Every locality in Delhi stores different water, and that decides how fast a tank fouls. This is Neb Sarai’s profile from The Delhi Water Index, built from our field observations across 250+ localities.

“Do you clean shared tanks on the apartment blocks in Neb Sarai?” Yes, we do both individual house tanks and the shared terrace tank banks on the apartment blocks. For a shared bank we send a larger crew and clean each tank in turn so flats are not left dry for long. Speak to your building association and we can quote for the full terrace in one visit.
“How much for a 1000L rooftop tank in a Neb Sarai builder floor?” A single 1000L overhead tank starts at ₹699, covering drain, sludge removal, jet wash, anti-bacterial disinfectant and the dated quality report. Because Neb Sarai runs on hard borewell water, a neglected tank may carry heavier scale, and we mention any change before starting. The base price holds for a normal tank.
“Can you come same-day to Freedom Fighter Enclave?” Usually yes for a single rooftop tank. Freedom Fighter Enclave and the wider Neb Sarai belt are part of our regular round, so if you call in the morning we can often reach the same afternoon. Same-day depends on how many jobs are already booked that day.
“Is the water safe to drink right after cleaning?” Yes. We finish with a anti-bacterial disinfectant made for drinking-water storage and rinse it out fully before you refill. Since the overhead tank is the last stop before your tap with no filter after it, a proper clean and disinfection is what makes the hard borewell water safe to use.
“How much water do you waste draining?” Only the scaled, silty water at the bottom you would not want anyway — the last few inches. We time the clean for when your tank is low so the loss is minimal. Clean water above the sludge line we leave in place where the plumbing allows.
