Strung along the Yamuna between Gandhi Nagar and the ITO bridge, Geeta Colony is a grid of decades-old houses whose ageing sumps often have not been opened in years. KaamGenie tackles these long-overdue buried tanks, from ₹1,499.
One of the old Trans-Yamuna colonies, Geeta Colony runs beside the river as a grid of decades-old houses and rebuilt floors. Supply is DJB with borewell backup, and the ageing overhead and plastic tanks on these older roofs carry years of scale, fed from sumps that have aged along with the buildings. In a settled colony like this, it is common for a sump to have gone untouched since the house was built, its floor thick with compacted sediment and its walls heavily scaled. That makes a first clean a bigger job than in a newer pocket, and a more overdue one.
We ventilate and air-test the sump, pump it down, break up and wet-vacuum the compacted bed, then jet-wash and disinfect before refill, flagging any structural wear we find. If the rooftop tank needs doing too, add our water tank cleaning in Geeta Colony. This page is about the ageing buried tank below.
In a decades-old house, a sump that has never been properly opened holds years of accumulated sediment, compacted into a firm bed that ordinary draining will not lift. The DJB and borewell mix has been dropping sand and mineral scale into it the whole time, building the layer season on season. Ageing RCC also tends to develop hairline cracks near the river, which let in seepage and add silt.
Because the colony is settled and the sump has always just worked, it slips out of mind entirely, often for the life of the house. The thick sludge bed and heavy wall scale shelter biofilm and dull the water reaching the taps. A proper first clean, breaking up and removing the compacted bed and descaling the walls, resets a tank that is genuinely years overdue.
No travel charge anywhere in Geeta Colony. The final price is confirmed on the call before we come — it depends only on tank size and access.

“Our sump has not been opened since the house was built. Is a first clean different?” It is a bigger job, but routine for us in Geeta Colony. Years of sediment compact into a firm bed, so we break it up and wet-vacuum it out and descale the heavily scaled walls, then disinfect. We also check the ageing RCC for cracks.
“The house is old and near the river. Could the sump be cracked?” It can be. Ageing RCC near the Yamuna sometimes develops hairline cracks that let in seepage. We dry-check the walls and floor after cleaning and flag anything structural in the photo report so you can seal it before it worsens.
“What does an overdue sump clean cost here?” From ₹1,499 for a sump up to 1,000 litres, with the price set by capacity. A first clean of a long-neglected tank may take longer for the compacted bed, but the price is by size, confirmed once we see it.
“Our tanks are old and scaled. Can you descale as well as de-silt?” Yes. Alongside removing the sludge bed, we work the years of chalky scale off the sump walls and floor, then disinfect the cleared surfaces, which matters on the ageing tanks common in Geeta Colony.
“How long does a first deep clean take?” For a long-settled house sump, allow a bit longer than routine, often half a day, since breaking up and removing a compacted bed and descaling old walls takes more work than a maintenance clean.
