Underground sump cleaning in Gurgaon — the ground-level reservoirs under kothis, DLF houses and society blocks, de-silted and disinfected under proper confined-space safety. From ₹1,499.
Almost every independent house and society in Gurgaon stores water in an underground sump before it is pumped up to the roof. On hard borewell supply, years of fine sand, silt and sludge settle into a thick layer at the bottom of that sump that no amount of topping up will disturb. In old Gurgaon kothis and DLF Phase 1 to 3 homes, these masonry sumps are large and rarely opened, so the muck simply keeps deepening season after season.
KaamGenie handles the whole job safely: we ventilate and test the sump air first, pump out the water, manually remove the silt and sludge, jet wash the walls and floor, disinfect with a food-grade sanitiser, and check for cracks or seepage before you refill. Sump work sits within our broader water tank cleaning in Gurgaon range. This page is specifically about the underground sump — the below-ground reservoir, not the tank on your roof.
Being below ground, a sump is the first place Gurgaon’s gritty borewell and canal water drops its load. Sand and fine silt sink and stay put, and because the sump is refilled from the bottom, that sediment is never flushed out on its own. In DLF and Sushant Lok houses the sump can hold thousands of litres, so a season’s worth of settled silt is a real, shovel-it-out quantity rather than a light rinse.
Sumps are also dark, cool and often poorly sealed, which suits bacteria and mosquito larvae far more than a bright rooftop tank does. Ground seepage after the monsoon, a cracked wall, or a loose cover in an old sector home can let in dirt and even small creatures. Because this is stored drinking water for the whole house, a neglected sump quietly contaminates every tap, which is why an annual clean matters.
No travel charge across Gurgaon. The final price is confirmed on the call — it depends only on tank size and access.

We reach every part of Gurgaon. A few of the areas we serve — tap yours:
“Which areas of Gurgaon do you cover for sump cleaning?” We clean underground sumps across Gurgaon — the kothis and independent houses of the old sectors and Civil Lines, DLF Phases 1 to 5, Sushant Lok, Ardee City, Badshahpur, Bhondsi and the society blocks along Golf Course Extension. Manesar-side and border colonies are covered too; just call and we will confirm access and a slot.
“What does underground sump cleaning cost in Gurgaon?” A small sump up to 1,000 litres starts at ₹1,499. A typical Gurgaon kothi sump of 1,001 to 2,000 litres runs ₹1,799 to ₹2,200, and 2,001 to 5,000 litres is ₹2,500 to ₹3,500. Large society underground tanks are quoted by capacity, with a bulk discount when several are done in one visit.
“Is sump cleaning safe, given it is a confined space?” Yes, and we take it seriously. A sump is a confined space, so before anyone enters we open it, test the air and ventilate it properly. Our crew is trained for this work. We would rather spend the extra minutes on ventilation and safety checks than rush a worker into an unventilated tank, which is a real hazard people underestimate.
“Can you clean the sump on the same day I call?” Sometimes. A small single sump can often be done same-day if you call early and we have a crew near your part of Gurgaon. Larger kothi and society sumps usually need a booked slot because pumping out and de-silting takes longer. We will give you an honest same-day answer rather than a maybe when you ring.
“Do I need to clean the sump if I already clean my overhead tank?” Yes. The overhead tank only holds what the sump pumps up, so if the sump floor is thick with silt and sludge, that dirty water reaches your roof and taps no matter how clean the rooftop tank is. On Gurgaon’s hard water we recommend doing both, and many customers clean the sump and overhead tanks together in one visit.
