In CR Park’s A-to-K blocks of kothis and builder floors, each floor’s plastic tank greens up on the shared roof. KaamGenie cleans your Sintex tank gently and food-grade. From ₹699.
Chittaranjan Park — CR Park — is a tight-knit A-to-K block neighbourhood of kothis and builder floors. Supply is DJB with borewell backup, and each floor typically keeps its own Sintex or plastic overhead tank, with shared underground sumps per plot. Because every builder floor stores separately in a plastic tank on the shared roof, there are many translucent tanks catching sun, each growing its own green film above the flat and feeding it, unfiltered, to the household below.
KaamGenie cleans the plastic overhead tanks across CR Park’s blocks — draining, wet-vacuuming the slimy sediment, soft jet-washing at a plastic-safe pressure and hand-scrubbing the algae with soft pads instead of wire brushes, then a food-grade disinfectant wash. If the shared plot sump needs doing too, see our full water tank cleaning in CR Park. This page is specifically about Sintex and plastic tanks.
On a CR Park builder floor, each flat’s Sintex tank sits on the shared roof in open sun. Light passes through the translucent plastic and warms the water, and algae and biofilm feed on that light and warmth. With several plastic tanks crowded on one roof, some catch direct sun most of the day. A concrete tank keeps its water dark and cooler, but the plastic tanks across CR Park’s blocks green up much sooner.
CR Park’s borewell backup adds hardness, so scale settles on the plastic floors and around outlets, and the algae film grips that rough layer. On upper builder floors the tanks are often the least-used and least-watched, so sediment and rooftop dust accumulate quietly between cleanings. In this close-knit residential grid, tanks sit near one another with little shade, so the sun works on the plastic all day and the film builds before anyone notices the water going off.
No travel charge anywhere in CR Park. The final price is confirmed on the call before we come — it depends only on tank size and access.

We reach every pocket of CR Park — and there’s no travel charge to any of them:
“Do you clean Sintex tanks in K Block CR Park?” Yes. K Block and all the A-to-K blocks, plus the pockets, are on our regular rounds. On these builder floors we clean your floor’s plastic overhead tank, or all the floors’ tanks on one roof in a single visit, and we can do the shared plot sump below in the same slot if you want it.
“How much to clean a 500-1000L Sintex tank in CR Park?” A Sintex tank up to 500 litres starts at ₹699 and a standard 1000L is ₹899. Larger tanks cost more by capacity. Since CR Park builder floors often share a roof of several plastic tanks, we give a bulk rate on four or more, so cleaning the whole building together is cheaper per tank.
“Can you come the same day to CR Park?” Usually yes. CR Park is central to our South Delhi routes, so a morning call to 95603 66362 often gets a crew to you the same day. If not, we fix a next-day slot around your DJB supply time so your plastic tank is cleaned and refilled without leaving your floor short of water.
“Why does my CR Park builder-floor plastic tank turn green?” Your Sintex tank shares an open roof and takes direct sun, and light through the translucent wall warms the water and feeds algae. The borewell backup leaves scale for the film to cling to, and on a lightly-used upper floor the water stands warm for longer, so the green film builds up quietly before anyone opens the tank.
“Do you use wire brushes on the algae?” No, never on plastic. Wire brushes scratch a Sintex wall and leave grooves that algae regrow into faster. We lift the film with a plastic-safe jet wash and soft pads, then a food-grade disinfectant wash, so your CR Park tank comes out smooth and stays cleaner longer after we finish.
