At the tail end of the DJB line, Hari Nagar Ashram’s walk-ups run borewell backup that scales plastic tanks hard and fast. KaamGenie descales and disinfects them plastic-safe, floor by floor. From ₹699.
Hari Nagar Ashram is the compact colony tucked behind Ashram Chowk toward the Yamuna side — narrow lanes and 3-4 storey walk-ups with one overhead plastic tank per floor, or one shared tank per building. Because the colony sits at the tail end of the DJB line, pressure is weak, and most buildings run borewell backup to keep the tanks filled. That borewell share is hard water, and inside a translucent plastic tank it lays down white scale and grit far faster than piped supply alone would.
KaamGenie cleans Sintex and plastic tanks across Hari Nagar Ashram — draining, wet-vacuuming the scale-and-silt layer off the ribbed plastic floor, soft jet-washing at plastic-safe pressure, hand-scrubbing the grooves with soft pads and finishing with a food-grade disinfectant wash and dated photos. If your building also needs the borewell sump or storage looked at, see our full water tank cleaning in Hari Nagar Ashram page.
Weak tail-end DJB pressure means the borewell does much of the filling here, and borewell water on the Yamuna side runs hard. Every fill leaves minerals behind on the plastic walls and in the moulded ribs of the tank floor, where scale builds into a rough crust you can feel with a hand. That rough surface then gives algae something to grip — and since sunlight passes straight through the translucent wall on these exposed walk-up roofs, the green film follows the scale within weeks.
The per-floor tank setup spreads the problem. A four-storey walk-up can have three or four separate 500-1000L tanks crowded on one small roof, each scaling at its own rate depending on how much borewell water it takes. Cleaning one and leaving the rest means half the building still drinks from crusted tanks, so we do the whole roof in one visit — every tank drained, descaled, scrubbed and disinfected, with per-tank photos so each floor sees its own result.
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:
“Can you clean all four tanks on our walk-up roof in one visit?” Yes, and that is how we recommend doing it in Hari Nagar Ashram. The crew drains and cleans each floor’s tank in sequence so the building is never fully without water, and every tank gets its own before-after photos. A combined visit is also cheaper per tank than booking floors separately.
“How much does it cost per tank?” Tanks up to 500 litres are ₹699 each and standard 1000L tanks are ₹899. For a walk-up roof with three or four tanks done together we quote a combined rate for the visit, so per-floor cost comes down. Heavy borewell scale is included in the clean — we do not add charges after seeing the tank.
“Our tank has a white crust we cannot scrub off — can you remove it?” Yes. That crust is hardened mineral scale from the borewell share, and it needs a proper soft jet-wash plus hand-scrubbing of the ribbed floor grooves where it packs in. We remove it without wire brushes, which would scratch the plastic and make the next crust form faster, and the tank comes out smooth.
“Do you do same-day visits in the narrow lanes here?” Usually yes — call before 10 AM on 95603 66362 and we can often reach Hari Nagar Ashram the same day. The lanes are narrow but the crew parks on the approach road and walks the equipment in; tight access is routine for us in this colony and never changes the price.
“How often should we clean, given the borewell backup?” Every six months, and every four months if your building leans heavily on the borewell in summer. Hard water scales a plastic tank two to three times faster than DJB supply alone, so the tail-end colonies like Hari Nagar Ashram need shorter cycles than the piped colonies across the Chowk.
