At the tail end of the DJB line, Hari Nagar Ashram’s walk-ups lean on borewell backup — and that hard water scales a rooftop tank in months. KaamGenie descales and disinfects overhead tanks across these narrow lanes. From ₹699.
Hari Nagar Ashram is a compact regularised colony tucked behind Ashram Chowk toward the Yamuna side — narrow lanes of 3-4 storey walk-ups where each floor keeps its own overhead plastic tank, or the whole building shares one. Sitting at the tail end of the DJB line, the colony gets weak piped pressure, so most buildings run a borewell backup. That groundwater is hard, and it coats tank walls with a whitish mineral scale remarkably fast.
Scale is not something a quick rinse removes. KaamGenie drains the tank, lifts out the sludge, breaks the scale down with a high-pressure jet, scrubs what the jet loosens, then disinfects with a food-grade solution before you refill — with photos and a dated certificate to close the job. This is our dedicated page for water tank cleaning in Hari Nagar Ashram.
Every time weak DJB pressure forces a borewell top-up, mineral-heavy groundwater enters the tank. As it sits and evaporates slightly in the heat, calcium and magnesium crystallise on the walls — the crusty white layer you can feel if you reach in. Under it, fine sand pulled up by the borewell settles into a dense bed at the base that boosters then churn into the taps of the upper floors.
The colony’s walk-ups compound this. Four floors drawing on one tank means high turnover; the tank refills from whichever source has pressure that hour, mixing DJB and borewell chemistry. Buildings here that clean their tanks every four to six months report visibly clearer water and fewer clogged tap aerators than those that wait for a problem.
No travel charge anywhere in Hari Nagar Ashram. The final price is confirmed on the call before we come — it depends only on tank size and access.

We reach every pocket of Hari Nagar Ashram — and there’s no travel charge to any of them:
“Our tank has a hard white crust inside. Can it actually be removed?” Yes — that is mineral scale from borewell water, and it is the most common thing we deal with in Hari Nagar Ashram. High-pressure jetting plus mechanical scrubbing takes it off plastic tank walls without damaging them. Very old, thick crusts may take an extra round, which we tell you upfront.
“How much does it cost for a 500L tank?” ₹699 covers a tank up to 500L end to end — drain, sludge removal, descaling jet wash, scrub, food-grade disinfection, certificate and photos. The 501-1,000L size is ₹899.
“The lane outside is too narrow for a van. How does the crew work?” Everything we need travels on two wheels or on shoulders — portable pump, hose reels, scrubbing kit and chemicals. Narrow-lane buildings are the bulk of our work in this colony; the crew parks at the lane mouth and walks the gear in.
“Should each floor’s tank be cleaned, or just the shared one?” Ideally all tanks on the roof in one visit — it costs less per tank and the whole building’s water improves together. We frequently do three or four floor-tanks in a single Hari Nagar Ashram booking and give a combined rate.
“Can you come today? Our water has turned muddy.” If you call before 10 AM, we can usually manage a same-day visit — the colony is minutes off our Ashram Chowk route. Muddy water after a borewell run usually means the sediment bed has been disturbed, and a full clean-out resolves it.
