In New Friends Colony’s elite kothis and premium builder floors near Jamia, big old plastic tanks on large plots green up quietly. KaamGenie cleans your Sintex tank gently and food-grade. From ₹699.
New Friends Colony is an elite area of large kothis and premium builder floors with a community centre, near Jamia. Supply is DJB with some borewells, and the big plots keep large individual Sintex or plastic overhead tanks and old underground sumps. On these spacious, open terraces the translucent plastic walls take full sun, so even in a quiet, upmarket colony the water grows a green film and biofilm inside a large tank that is opened only occasionally, feeding the household unfiltered until it is finally cleaned.
KaamGenie cleans the large plastic overhead tanks across New Friends Colony’s kothis and builder floors — draining, wet-vacuuming the slimy sediment, soft jet-washing at a plastic-safe pressure and hand-scrubbing the algae with soft pads rather than wire brushes, then a food-grade disinfectant wash. If the old underground sump needs doing too, see our full water tank cleaning in New Friends Colony. This page is specifically about Sintex and plastic tanks.
The big plastic tanks on New Friends Colony’s large kothis sit high and fully exposed on wide terraces. Light passes through the translucent Sintex wall and warms the water, and that light and warmth is exactly what algae and biofilm need. Because the plots are large and open, there is little shade over the tanks, so the sun works on them all day. Concrete tanks stay dark and clearer inside, but the plastic tanks here green up sooner.
The bigger issue is time and volume. These large tanks hold a lot of water that turns over slowly, so it stands warm and still — ideal for the film to spread. On premium plots where the sump does much of the storing, the rooftop plastic tank is opened only occasionally, so borewell scale, dust and biofilm build up undisturbed for long stretches. By the time such a tank is finally opened, the slimy film is well established, which is why we scrub it gently.
No travel charge anywhere in New Friends Colony. The final price is confirmed on the call before we come — it depends only on tank size and access.

We reach every pocket of New Friends Colony — and there’s no travel charge to any of them:
“Do you clean Sintex tanks in B Block New Friends Colony?” Yes. B Block and all of New Friends Colony, plus the community centre side, are on our regular rounds. On these large kothis and builder floors we clean the big plastic overhead tank, and where it has not been opened in a long time we take extra care lifting the settled film gently, plus do the old sump in the same visit if you want it.
“How much to clean a 500-1000L Sintex tank in New Friends Colony?” A Sintex tank up to 500 litres starts at ₹699 and a standard 1000L is ₹899. The larger plastic tanks common on New Friends Colony kothis cost more by capacity, and where a plot has several tanks we give a bulk rate on four or more, so the whole house is cleaned economically in one visit.
“Can you come the same day to New Friends Colony?” Usually yes. New Friends Colony is on our South Delhi routes near Jamia, so a morning call to 95603 66362 often gets a crew to you the same day. For a large tank that has not been opened in a while we may suggest a longer slot, but we still work around your household’s water timing.
“Why does my big New Friends Colony plastic tank go green?” A large tank greens up quietly because its big volume turns over slowly, so the water stands warm and still, and light through the translucent Sintex wall feeds algae the whole time. Where the sump stores most of the water, the rooftop tank is opened rarely, so the film and borewell scale build up unnoticed until the water finally goes off.
“Will your cleaning damage my old plastic tank?” No. Older plastic is more brittle, so we set the jet pressure for plastic to clear the film and scale without cracking the wall, and we scrub with soft pads, never wire brushes. Wire brushes would scratch and weaken old plastic and speed algae regrowth, so we keep your New Friends Colony tank smooth and clean.
