Underground Sump Cleaning: Cost & Safety

Out on the Asola ridge, your rooftop tank is the final stop before the tap — and the hard borewell water here leaves scale like nowhere else. KaamGenie cleans overhead RCC and Sintex tanks across the farmhouses and kothis. From ₹699.
Asola is a semi-rural fringe village on the ridge beside the Asola Bhatti Wildlife Sanctuary, made up of farmhouses, banquet plots and low-density kothis rather than flatted colonies. There is barely any DJB piped supply out here, so water comes mainly from deep borewells and tankers and runs hard and high in TDS. On a rooftop overhead tank that mineral load bakes into thick scale on the walls, while ridge dust and grit settle into a heavy sludge on the floor.
KaamGenie handles these rooftop tanks end to end — we drain them, scoop the sludge, high-pressure jet-wash the scale, hand-scrub every corner, then wash down with a food-grade disinfectant and hand you dated before/after photos and a certificate. This is our dedicated page for water tank cleaning in Asola, focused specifically on the overhead (rooftop) tanks that feed your taps.
Because there is no reliable DJB line, Asola homes run almost entirely on deep borewell water, which is some of the hardest in South Delhi. Every fill carries a dose of dissolved calcium and magnesium that sets hard on the tank walls once the water stands still. On the large rooftop tanks common at these farmhouses, that means a visible chalky crust builds up within a couple of months, not years.
The rocky ridge terrain kicks up a lot of fine dust, and with big open plots and banquet grounds nearby, that dust drifts onto rooftops and into any tank with a poorly sealed lid. Since nothing filters the water after the overhead tank, that grit and any scale flakes go straight to your taps. A proper clean two to three times a year is the only way to keep the stored water clear on this kind of supply.
No travel charge anywhere in Asola. The final price is confirmed on the call before we come — it depends only on tank size and access.

We reach every pocket of Asola — and there’s no travel charge to any of them:
“Do you actually come out this far to Asola for one tank?” Yes. We run regular rounds across the Asola, Bhati and Chattarpur belt, so a single rooftop tank is no problem. Because it is a fringe area we usually confirm a morning slot so the crew can plan the drive, but there is no extra charge just for the location. Give us the landmark or farmhouse name off the Bhati Mines road and we will find you.
“My borewell water leaves white scale within weeks. Can you get it off?” That white crust is hardness scale from the deep borewell water, and yes, we remove it. We use a high-pressure jet to break the scale off the walls, then hand-scrub the stubborn patches in the corners and joints. On very heavily scaled RCC tanks we may recommend a slightly longer clean, but it comes off and the walls come back smooth.
“How much does it cost for a big farmhouse overhead tank?” Pricing starts from ₹699 for a standard 1000L tank, and larger farmhouse RCC tanks are quoted by capacity once you tell us the size. Many Asola homes have 2000L to 5000L rooftop tanks, so we give you an exact figure on the phone rather than a range. There is no charge for the site look if you are unsure of the volume.
“Is it safe to drink the water straight after cleaning?” Yes. We finish with a food-grade disinfectant wash at the right dose and rinse it out, so the water is safe the moment the tank refills. It is the same standard used for drinking-water tanks, safe for the whole family. On borewell supply this final step matters, because it clears any biofilm the scale was hiding.
“Can you clean the underground sump and the rooftop tank together?” We can, though this page is about the rooftop overhead tank that feeds your taps. Many Asola properties pair a large RCC sump with a rooftop tank, and doing both in one visit is more thorough and cheaper per tank. Tell us both capacities when you call and we will quote the pair together.
