Underground Sump Cleaning: Cost & Safety

In Vasant Kunj, where low DJB pressure means most blocks pump from a sump up to a plastic rooftop tank, that Sintex store grows algae in the ridge-edge sun. KaamGenie cleans it gently and food-grade. From ₹699.
Vasant Kunj is a large DDA pocket of A/B/C/D blocks and sectors, mid-rise flats and premium condominiums on the Aravalli ridge edge. DJB pressure here is often low, so most blocks lean on borewell and big underground sumps that pump up to rooftop tanks — and those rooftop stores are usually Sintex or plastic. Sitting on open terraces in strong ridge sun, the translucent tanks warm up and grow a green film that no downstream filter removes before it reaches your tap.
KaamGenie cleans the plastic rooftop tanks across Vasant Kunj — draining, wet-vacuuming the slimy sediment, soft jet-washing at a plastic-safe pressure and hand-scrubbing the algae with soft pads, not wire brushes, then a food-grade disinfectant wash. If you also want the feeding underground sump done in the same visit, see our full water tank cleaning in Vasant Kunj. This page is specifically about Sintex and plastic tanks.
Because DJB pressure is weak here, Vasant Kunj tanks are filled by pumping from a sump, and the water often sits longer in the rooftop plastic tank between top-ups. On the open, sun-exposed terraces along the ridge, light passes through the translucent Sintex wall and warms that standing water — ideal conditions for algae and biofilm. A concrete tank would keep the water dark and cooler, but plastic lets the light in, so the film blooms noticeably faster.
The borewell that Vasant Kunj blocks rely on is hard, and pumping it up from a sump carries fine sediment and scale into the rooftop plastic tank. That grit settles on the floor and around the outlet, and the algae film grips onto it. Ridge dust blowing across the terraces also drifts in through lids that are rarely reseated properly after pump servicing, so the tank collects two sources of dirt at once between cleanings.
No travel charge anywhere in Vasant Kunj. The final price is confirmed on the call before we come — it depends only on tank size and access.

We reach every pocket of Vasant Kunj — and there’s no travel charge to any of them:
“Do you clean Sintex tanks in Sector C Vasant Kunj?” Yes. Sector C and the other Vasant Kunj sectors and pockets are on our regular routes. Whether it is a mid-rise flat with a single plastic rooftop tank or a condominium with several, our crew reaches you and cleans each Sintex tank gently, and we can do the underground sump that feeds it in the same slot.
“What is the cost for a 500-1000L Sintex tank in Vasant Kunj?” A Sintex tank up to 500 litres starts at ₹699 and a standard 1000L is ₹899. Larger 2000L rooftop tanks cost more, and where a Vasant Kunj block has several plastic tanks we give a bulk rate on four or more, so the whole building is cheaper per tank in a single visit.
“Can you come the same day to Vasant Kunj?” Usually yes, if you call 95603 66362 in the morning. Because water sits longer in Vasant Kunj tanks between pump fills, same-day cleaning is worth it. If the day is booked we fix a next-day time around your pumping schedule so the tank is clean and refilled before the block needs it.
“Why does my Vasant Kunj plastic tank go green so fast?” The water here is pumped up and then stands in your rooftop Sintex tank, which sits in strong ridge sun. Light through the translucent plastic warms that standing water and feeds algae, while the hard borewell content leaves scale for it to cling to. Standing water plus light in a plastic tank is the fastest recipe for a green film.
“Will the jet wash damage my Sintex tank walls?” No. We match the jet pressure to plastic so it clears scale and biofilm without cracking or gouging the wall, and we finish stubborn algae with soft pads rather than wire brushes. Since a scratched Sintex wall grows algae back quicker, we keep the surface smooth on purpose on every Vasant Kunj tank we clean.
