Underground sump cleaning in Connaught Place — the large commercial-building reservoirs beneath the colonial blocks that feed offices, showrooms, cafes and restaurant kitchens, where heavy footfall demands a scheduled, hygienic clean. Confined-space trained crews. From ₹1,499.
Under the colonial arcades of Connaught Place, the water story is entirely commercial. The circular blocks house offices, showrooms, cafes and restaurants, and each building keeps a large underground reservoir that holds the day's piped DJB water before booster pumps push it up to the overhead tanks and out to kitchens and washrooms. Heavy, continuous footfall through the cafes and offices means an enormous volume passes through those buried tanks every day. Sediment carried in the supply settles out in the reservoir, and standing water over it lets biofilm develop fast. For restaurant kitchens especially, a lapse in the cleaning schedule quickly shows up in the water quality, so these sumps need a proper, planned service.
KaamGenie cleans these large CP commercial reservoirs end to end. We open and ventilate the tank, test the air, pump the water down to the sludge line, scoop and wet-vacuum the silt, then jet the caked mud and biofilm off the floor and walls before an anti-bacterial disinfectant wash and a clean-water rinse, with before and after photos for the facility record. A big basement reservoir can hold stale, low-oxygen air, so every entry is a confined-space job: we ventilate and air-test first and keep a spotter at the opening. If the overhead tanks need servicing in the same visit, see our water tank cleaning in Connaught Place; this page is about the underground reservoir specifically.
The reservoir takes the first fill for the whole building, so the sediment in the DJB line settles to the bottom before the water is pumped up to the offices and kitchens. With cafes, restaurants and busy washrooms drawing all day, the volume through one buried tank is large, and the sludge bed rebuilds quickly. Standing commercial water over that sludge grows biofilm on the walls that a rushed clean will not remove.
The reservoir sits in a basement plant room, out of sight and easy to let slip until the water tastes or smells off, which for a food business is a real problem. Older CP buildings can have reservoirs that develop cracks and let seepage in, and a sealed one holds stagnant air over the sludge. Our crews ventilate and air-test every reservoir before entry and inspect the structure while it is open, so facility managers get a documented, hygienic result.
No travel charge anywhere in Connaught Place. The final price is confirmed on the call before we come — it depends only on tank size and access.

“We run a restaurant in CP. Can you clean without closing the kitchen?” Usually, yes. We schedule around your service hours and work while the overhead tanks hold enough to keep the kitchen running, or we take an early slot before opening. We plan it with your manager so the clean does not interrupt food service.
“How often should a commercial reservoir here be cleaned?” For a building feeding cafes, restaurants and busy washrooms, twice a year is a sensible minimum, and some kitchens prefer quarterly. The heavy throughput rebuilds the sludge bed fast, so we will recommend a schedule after the first clean.
“What does it cost for a large commercial reservoir?” Small tanks up to 1,000 litres start at ₹1,499, but most CP reservoirs are larger: 1,001 to 2,000 litres runs ₹1,799 to ₹2,200, 2,001 to 5,000 litres is ₹2,500 to ₹3,500, and bigger reservoirs are quoted by capacity after we see them.
“Do you provide photos for our facility records?” Yes. We send before and after photos of the reservoir on WhatsApp after every clean, which facility and building managers keep for their maintenance records and can share with tenants or auditors.
“Is the basement reservoir safe for your crew to enter?” It is when handled properly. A big sealed reservoir can hold low-oxygen air, so our crews are trained for confined-space entry: we open and ventilate the tank, test the air, and keep a spotter at the opening the whole time. Safety comes before anything else.
