In Okhla Phase 2, the plastic and Sintex tanks feeding factory canteens and offices run on hard borewell water and slime up fast through their sunlit walls. We clean them gently and food-grade. From ₹699.
Okhla Industrial Area Phase 2 is a busy mix of factories, institutes and offices, and it leans heavily on borewell water. Storage runs to large industrial overhead tanks and underground reservoirs, and hygiene matters here because much of that water goes to canteens and process use. Many of the overhead tanks are plastic or Sintex, fitted for quick, low-cost storage on unit rooftops. Where water quality feeds staff meals or a process, a plastic tank quietly growing algae is more than a nuisance — it is a hygiene risk.
The heavy borewell reliance in Phase 2 means hard water, which leaves a stubborn scale on plastic between cleans. If a unit also needs its underground reservoir cleaned or the whole premises done together, our full water tank cleaning in Okhla Phase 2 page covers it. This page is specifically about Sintex and plastic tanks — the overhead tanks feeding canteens and process water that need gentle, hygienic cleaning.
A plastic overhead tank on a Phase 2 unit sits in open sun, and light through its walls is what green algae feed on. Where it supplies a canteen, the water is warm and refilled through the day, extending the growing hours. A concrete tank would stay dark and cool inside and slow a bloom, but Sintex and plastic let the daylight straight through and warm through with it. For canteen or process water, that means a green film and biofilm can build quickly, which is a real hygiene concern for the unit.
The hard borewell water makes it worse. Phase 2 groundwater is heavily mineralised, so a thick, chalky scale forms on plastic floors and around outlets, and slime clings to that rough surface. Industrial dust blows in through lids that rarely seal on unit roofs. With the tank drawn down and refilled through each shift, the sediment never settles out for removal. Scale and biofilm together leave a heavy, slippery coating that only a full drain, plastic-safe scrub and sanitiser can properly clear.
No travel charge anywhere in Okhla Phase 2. The final price is confirmed on the call before we come — it depends only on tank size and access.

We reach every pocket of Okhla Phase 2 — and there’s no travel charge to any of them:
“Do you clean Sintex tanks for units in Okhla Phase 2 near Govindpuri Metro?” Yes. We clean plastic and Sintex tanks for factories, institutes and offices across Okhla Phase 2, including the blocks near Govindpuri Metro, Jasola and Sarita Vihar. Whether the tank feeds a canteen or process water, we plan a slot around your working hours and clean it to a food-grade standard.
“What does it cost to clean a 500 to 1000 litre Sintex tank here?” A plastic tank up to 500 litres starts at ₹699 and a 1000 litre Sintex tank is ₹899, covering draining, scale and slime removal, a plastic-safe wash, hand-scrubbing and a food-grade sanitiser. Larger industrial tanks are quoted by capacity, with a bulk discount when several tanks on one premises are cleaned together in one visit.
“Can you clean my plastic tank the same day I call?” Often yes. Okhla Phase 2 is on our regular industrial route, so same-day or next-day visits are usually possible. A single Sintex tank takes about ninety minutes; for a unit with several tanks we agree a slot that does not disrupt the canteen or process, and confirm timing when you call.
“Why does my Sintex tank in Okhla Phase 2 grow algae and scale so fast?” Phase 2 overhead tanks are mostly plastic, so light passes through the walls to feed algae, and canteen tanks stay warm and refill through each shift. The hard borewell water adds scale that traps slime. The moving water only feeds the film, so it and the scale return unless the tank is properly scrubbed and disinfected.
“Is pressure washing safe for a plastic tank, and how do you remove algae without scratching it?” It is safe because we set the pressure for plastic, so even large Sintex tanks are not cracked or gouged. Scale and algae come off with soft pads and plastic-safe methods, never wire brushes, which scratch the surface and let biofilm return. A food-grade sanitiser then clears the spores, which matters for canteen and process water.
