Water Tank Cleaning Rules & Norms

In Sheikh Sarai, the shared plastic and Sintex tanks on DDA flats and builder floors near Malviya Nagar quietly grow algae through their sunlit walls. We clean them gently, food-grade and photo-documented. From ₹699.
Sheikh Sarai spreads across DDA flats in Phase 1 and Phase 2 and surrounding builder floors near Malviya Nagar and Chirag Delhi. Water is stored in shared society overhead tanks and plot-level sumps, and on the rooftops those overhead tanks are usually plastic or Sintex. A shared tank feeds several flats at once, so it is refilled steadily through the day. Sitting in open sun on the flat roofs, the plastic lets daylight through, and that light is exactly what lets algae take hold inside.
The colony runs on DJB with borewell backup, and that backup water leaves scale on plastic between cleans. If your block also needs its underground sump done or you want the whole society handled together, our full water tank cleaning in Sheikh Sarai page covers it. This page is specifically about Sintex and plastic tanks — the shared rooftop overhead tanks that go green and slimy first.
The plastic society tanks on Sheikh Sarai rooftops sit in open sun on the DDA flat blocks, and light through their walls is exactly what green algae feed on. Feeding several flats, the water stays lukewarm from steady use and the rooftop heat, which extends the growing hours. A concrete tank would stay dark and cool inside and slow a bloom, but Sintex and plastic light up and warm through, so a green film spreads across the walls sooner than residents expect after a clean.
The water supply adds the rest. When the borewell backup runs during shortages, it brings dissolved minerals that settle as a pale scale on the plastic floor and around the outlet, where slime clings. Dust drifts in through lids that no longer seal on the older society tanks. Because a shared tank is refilled several times a day for a full block, the silt never settles out for removal, so the scale and biofilm build into a slippery, gritty layer between cleans.
No travel charge anywhere in Sheikh Sarai. The final price is confirmed on the call before we come — it depends only on tank size and access.

We reach every pocket of Sheikh Sarai — and there’s no travel charge to any of them:
“Do you clean Sintex tanks in Sheikh Sarai Phase 1 and Phase 2?” Yes. We cover all of Sheikh Sarai, including the Phase 1 and Phase 2 DDA flats and the builder floors towards Malviya Nagar and Chirag Delhi. Whether it is a single flat’s plastic tank or a shared society tank on the roof, we can schedule them together and clean them in one visit.
“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 standard 1000 litre Sintex tank is ₹899. The price covers draining, sediment and slime removal, a plastic-safe jet wash, hand-scrubbing and a food-grade disinfectant, with photos afterwards. A society with several shared tanks on one block gets a bulk discount on four or more done together.
“Can you clean my plastic tank the same day I call?” Usually yes. Sheikh Sarai sits on our regular Malviya Nagar routes, so same-day or next-day slots are normally available. One standard Sintex tank takes about ninety minutes; for a block with several shared tanks we plan a slot that keeps the flats supplied, and confirm timing when you call.
“Why does my shared Sintex tank in Sheikh Sarai keep going green?” Sheikh Sarai’s shared tanks are plastic and sit in open sun on the flat roofs, so light passes through the walls to feed algae while steady use keeps the water warm. A shared tank refills several times a day, which keeps the film supplied. Rinsing does not remove it, so the green, slimy layer returns within weeks unless the walls are scrubbed.
“Is pressure washing safe for a plastic tank, and how do you remove algae without scratching it?” It is safe when the pressure is set for plastic, which is exactly what we do, so the Sintex walls are never gouged or cracked. Algae is removed with soft pads instead of wire brushes, because wire leaves scratches that let biofilm grip and regrow faster. A food-grade sanitiser then clears the last spores before the tank refills.
