C Block sits in the later, more crowded stretch of the Nand Nagri grid, its rebuilt floors packed tighter than A Block and its ground sumps working harder for it. The chalky borewell leaves a bed that a drain-and-scrub clears, and KaamGenie starts at ₹1,499.
Where A Block keeps the older resettlement layout, C Block is the denser, more rebuilt stretch of the Nand Nagri grid, EWS blocks and added floors crowded onto busy lanes. Water is largely borewell and tanker, hard and prone to a chalky scale, drawn into ground-level sumps before pumps lift it to small rooftop tanks feeding several families each. The heavier build-up and higher occupancy in C Block mean the buried tanks here take a bigger draw than A Block's, so the sediment and scale rebuild faster between cleans.
We clear the buried tank thoroughly: open and ventilate it, air-test before entry, pump down the standing water, scrape the chalky scale and lift the settled silt by hand, wet-vacuum, jet-wash and disinfect to a hygienic finish. Residents wanting the rooftop tanks done as well can see our water tank cleaning in Nand Nagri (C Block). This page is about the underground sump, the harder-worked tank in the denser C Block stretch.
C Block's higher occupancy is the difference. More rebuilt floors and more families drawing off each buried tank mean a heavier daily throughput than the older A Block clusters, so the pump runs more and the level swings low more often. The chalky borewell drops scale on the walls and grit on the floor, and in a harder-worked sump that load rebuilds quickly after every clean. Tanker top-ups add their transit sediment on top.
A busy shared tank running low often keeps the pump close to the sediment bed, so the settled scale and biofilm are drawn up to the rooftop tanks and the taps more readily than in a quieter block. Because C Block's buried tanks serve many families and belong to no single household, they slip past the maintenance most homes give a private tank. A full scrub-out clears the accumulated load, and a shorter cleaning interval keeps the denser block's sump from silting straight back up.

“Our C Block tank silts up faster than we expect. Why is that?” C Block is more crowded and rebuilt than the older blocks, so more families draw off each buried tank and the pump runs harder. That heavier throughput rebuilds the sediment and scale faster, which is why a shorter cleaning interval helps here.
“There is a chalky crust in the tank. Can you remove it?” Yes. That is hard-water scale from the borewell. We scrape and jet-wash it off the walls and floor when we clean the sump. Very old scale may not come fully back to bare concrete in one go, but we take it right down.
“What does a C Block sump clean cost?” From ₹1,499 for up to 1,000 litres. Shared block tanks are priced by capacity, and neighbouring clusters booking together share a discounted visit.
“Several families share our sump. How do you handle the timing?” We fix a window when the block can be off supply for a few hours, drain and scrub the buried tank, and restore the pump the same day, letting the households know in advance so everyone plans around it.
“How often should the denser C Block sumps be cleaned?” About every nine months given the higher occupancy and the chalky borewell, a bit sooner than the quieter blocks, because the harder-worked tank rebuilds its bed faster.
