Overhead vs Underground Tank Cleaning

Screened from Vikas Marg by its showrooms and offices, the houses and builder floors of Nirman Vihar keep rooftop plastic tanks that catch the road's dust through every loose lid. KaamGenie clears the sediment, scrubs the walls and disinfects, from ₹699.
Nirman Vihar is a commercial-and-residential pocket wrapped around the metro on Vikas Marg, its showrooms and offices fronting a quieter grid of older houses and builder floors behind. Homes draw DJB supply into rooftop overhead tanks, and the mixed commercial use means many buildings also run an underground sump. Sitting close to one of East Delhi's busiest roads, these rooftops collect a steady fall of traffic dust that settles into open or ill-fitting Sintex tanks. That airborne grit adds to the ordinary sediment, so the plastic tanks here carry more on their floors than a quieter colony's would.
A clean here means draining the tank, wet-vacuuming the dust-laden sludge, scrubbing the plastic walls with soft pads and finishing with a anti-bacterial disinfectant wash plus before-and-after photos. Buildings with a sump behind the frontage often do both under our wider water tank cleaning in Nirman Vihar. This page is about the rooftop Sintex and plastic tanks that take the brunt of the Marg's dust.
Two things work on a plastic tank here at once. First, the translucent wall lets Vikas Marg's daylight through to warm the water and start an algal film, the same weakness every Sintex tank has on an open roof. Second, the road's dust drifts up and settles through any gap in the lid, so the tank gains a layer of fine grit that a concrete tank in a leafy colony would never see. Together they load the tank faster than either would alone.
The dust binds into the sediment on the floor and the biofilm on the walls, and because the water sits above a busy road it rarely gets the still, cool conditions that keep a tank clean. Residents notice it as a gritty residue in the first pour and a taste that goes flat by afternoon. Clearing it means lifting the settled dust, scrubbing the film and closing the lid properly, which a top-up flush cannot do.
No travel charge anywhere in Nirman Vihar. The final price is confirmed on the call before we come — it depends only on tank size and access.

“Does the dust from Vikas Marg really get into a rooftop tank?” Through a loose or badly fitting lid, yes. Fine road dust settles onto the roof and blows into any gap, ending up in the sediment on the tank floor. We clear that out and can advise on sealing the lid so less gets in between cleans.
“Can you clean a tank on a mixed commercial-residential building?” Yes. We handle rooftop tanks whether the building is homes, offices or a mix, and we schedule around the working day so the water is off at a convenient time. The plastic-safe scrub is the same regardless of what the floors below are used for.
“What is the cost for a standard rooftop plastic tank?” It starts at ₹699 for a tank up to 500 litres, a little more for 1000L. A building with a sump as well, or several tanks, is quoted together at a per-tank rate.
“How often should a tank near a busy road be cleaned?” More often than a quiet colony's, because of the added dust load. Twice a year is a reasonable minimum here and quarterly is better if the lid is not tight, since the grit builds up faster than in a sheltered spot.
“Will scrubbing scratch the inside of my Sintex tank?” No. We use soft pads and a pressure set for plastic, never wire brushes, so the wall is cleaned without scratches. Scratches matter because algae and dust settle into them faster, which is exactly what we are trying to avoid.
