Sintex & Plastic Tank Cleaning in Anand Niketan

Sintex & plastic tanks in Anand Niketan

Anand Niketan is an elite, low-rise colony of large independent kothis and diplomatic residences near Chanakyapuri, where water usually comes off big overhead tanks and underground sumps. Alongside the main tanks, most of these houses also run smaller Sintex or plastic tanks for lofts, servant quarters and terrace kitchens. Because the households are small relative to the storage, these plastic tanks often sit still for long stretches — and still, sunlit water in a plastic tank is where algae thrive.

Supply here is mostly DJB, and the tanks tend to be old and rarely opened, which is precisely why the plastic ones need attention. If you want the large overhead tanks and underground sump handled as well, our broader water tank cleaning in Anand Niketan page covers those. This page is specifically about the Sintex and plastic tanks that grow algae quietly while nobody is looking inside them.

Why plastic tanks in Anand Niketan grow algae even when barely used

In a large Anand Niketan kothi the plastic loft tank may serve only a few people, so the water sits for days rather than being drawn down. That still water, warmed by the sun through the translucent walls, is ideal for algae, which need only light and time. A concrete tank would stay dark inside, but plastic and Sintex let daylight through, so even a lightly used tank slowly turns its water green and coats the walls with film.

The second issue is neglect. Because these tanks are tucked on terraces and rarely opened, scale from years of hard water and a soft sludge of settled dust simply accumulates undisturbed. Some kothis draw on private borewells that add extra mineral load, leaving a chalky crust on the plastic. By the time a lid finally comes off, there is often a thick biofilm and a musty smell that only a full drain, scrub and disinfection will clear.

How we do it — our 8-step process

• 1. Inspect & drain We check the tank and lid, then drain it down, saving what clean water we can.
• 2. Sediment removal Settled grit and the slimy layer at the bottom are scooped and wet-vacuumed out.
• 3. Soft jet wash Walls, floor and ceiling are jet-washed at a pressure safe for plastic — no gouging or cracking.
• 4. Manual scrub The algae film and inlet/outlet mouths are hand-scrubbed with soft pads, not wire brushes.
• 5. Anti-bacterial treatment A food-grade disinfectant wash kills remaining bacteria and algae spores.
• 6. Vacuum & rinse Loosened dirt is vacuumed out and the tank rinsed clean and ready to refill.
• 7. Lid & overflow check We reseat the lid and check the overflow so light and dust can’t feed new algae.
• 8. Photos & certificate Before/after photos and a dated service record sent to you on WhatsApp.

Common questions from Anand Niketan customers

“Do you cover the kothis in Anand Niketan B and C blocks?” Yes. We clean plastic and Sintex tanks across all of Anand Niketan, including A, B and C blocks and the houses near Nyaya Marg and San Martin Marg. Many of these tanks have not been opened in years, so we plan a little extra time for the heavier build-up we usually find.

“What does it cost to clean a 500 to 1000 litre Sintex tank here?” For a plastic loft tank up to 500 litres the rate starts at ₹699, and a 1000 litre Sintex tank is ₹899. That covers draining, clearing the sludge, a plastic-safe wash, hand-scrubbing and a food-grade sanitiser. A large kothi often has several tanks, and we give a bulk discount when four or more are done in one visit.

“Can you clean my plastic tank the same day I call?” Usually we can manage same-day or next-morning for Anand Niketan. A single plastic tank takes about ninety minutes, though a long-neglected one with heavy algae can run a little over. We will tell you honestly on the call, and your supply is back to normal the same day once the tank refills.

“Why does my Sintex tank in Anand Niketan turn green even though it is barely used?” Even a lightly used plastic tank turns green here because the walls let sunlight in, and light on still, warm water is all algae need. In many Anand Niketan homes the loft tank serves only a few people, so the water sits for days and the film has time to spread. Rinsing alone never removes it; the walls must be scrubbed.

“Is pressure washing safe for a plastic tank, and how do you remove algae without scratching it?” Very safe. We wash Sintex and plastic tanks at a pressure set for the material, so there is no cracking or gouging even on an older, sun-brittled tank. Algae comes off with soft pads, never wire brushes, which would scratch the plastic and help biofilm return faster. A food-grade disinfectant then kills the remaining spores before we refill.
