In Green Park’s leafy kothis and builder floors near AIIMS, older rooftop plastic tanks green up quietly in the sun. KaamGenie cleans your Sintex tank gently and food-grade. From ₹699.
Green Park is a leafy colony — Main and Extension — of kothis and builder floors near AIIMS and the market. Supply is DJB with some borewells, and each floor typically keeps an individual Sintex or plastic rooftop tank, with plot-level underground sumps and many older buildings. On the open terraces, the translucent plastic walls let light and warmth into the water, and in these older buildings the tanks are often opened rarely, so a green film builds up quietly before anyone thinks to look inside.
KaamGenie cleans the plastic rooftop tanks across Green Park Main and Extension — 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 plot sump needs doing as well, see our full water tank cleaning in Green Park. This page is specifically about Sintex and plastic tanks.
A Green Park plastic tank on a kothi or builder-floor roof sits in open sun for much of the day, and while the colony is leafy at street level, the terraces above the trees are still exposed. Light passes through the translucent Sintex wall and warms the water, feeding algae and biofilm. A concrete tank stays dark and clearer inside, but the plastic tanks here green up faster simply because the light gets in and warms the water.
Many Green Park buildings are older, and their rooftop plastic tanks are opened only occasionally, so sediment, borewell scale and dust accumulate undisturbed while the algae film thickens. The borewell backup used when DJB is short leaves a rough mineral layer on the plastic floor for the film to grip. Being near AIIMS and the busy market, there is plenty of dust and traffic grime that drifts into tanks through ageing, loosely-fitting lids between cleanings.
No travel charge anywhere in Green 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 Green Park — and there’s no travel charge to any of them:
“Do you clean Sintex tanks in Green Park Extension?” Yes. Green Park Main and Extension, plus the market side, are on our regular rounds. On these kothis and builder floors we clean the rooftop plastic tank, and in an older building where the tank has not been opened in a while we take extra care lifting the settled film gently off the ageing plastic wall.
“How much to clean a 500-1000L Sintex tank in Green Park?” A Sintex tank up to 500 litres starts at ₹699 and a standard 1000L is ₹899. Larger tanks cost more by capacity, and where a Green Park building has several plastic tanks we give a bulk rate on four or more, so the whole property is cleaner per tank in one visit.
“Can you come the same day to Green Park?” Usually yes. Green Park is central to our South Delhi routes, so a morning call to 95603 66362 often gets a crew to you the same day. For an older tank that has not been opened in a while we may suggest a slightly longer slot, but we still work around your DJB supply timing.
“Why does my older Green Park plastic tank look green inside?” Because it has had months or years of light through its translucent walls feeding algae, plus borewell scale and dust settling undisturbed. In an older building the rooftop Sintex tank is opened rarely, so the green film just keeps thickening on the warm, sunlit water until it is finally cleaned.
“Will jet-washing damage my Sintex tank?” No. We set the jet pressure for plastic, so it clears the film and scale without cracking or gouging the wall, and we finish with soft pads, never wire brushes. On older plastic especially, wire brushes would scratch and weaken it, so we keep the surface smooth so your Green Park tank stays cleaner for longer.
