In Maharani Bagh, the plastic and Sintex loft tanks on very large kothis often sit unopened for months while algae builds through their sunlit walls. We clean them gently and food-grade. From ₹699.
Maharani Bagh is an elite colony of very large independent kothis on generous plots near New Friends Colony and Nizamuddin. Water usually comes off big individual overhead tanks and underground sumps, but nearly every house also keeps Sintex or plastic tanks for lofts, terraces and staff areas. With small households and plenty of storage, these plastic tanks often hold water that sits for long stretches without being drawn down. Still, sunlit water in a plastic tank is exactly the condition algae need to bloom.
Supply here mixes DJB with private borewells, and the borewell water leaves a heavy mineral scale on plastic over time. If you want the large overhead tanks and underground sump cleaned as well, our broader water tank cleaning in Maharani Bagh page covers those. This page is specifically about Sintex and plastic tanks — the smaller overhead tanks that grow algae quietly on these big, calm rooftops.
In a large Maharani Bagh kothi a plastic loft tank may serve only a few people, so its water sits for days rather than turning over. Warmed by the sun through the plastic and lit by that same daylight, the still water becomes ideal for algae, which need only light and time. A concrete tank stays dark and slows any bloom, but Sintex and plastic let the light straight through, so even a lightly used tank turns green and coats its walls with film.
Neglect completes the picture. These loft and terrace tanks are tucked away and rarely opened, so years of hard-water scale and settled dust build up undisturbed. The private borewells common in the colony add extra mineral, leaving a thick chalky crust on the plastic floor. By the time a lid is finally lifted, there is usually a heavy biofilm and a stale smell that only a full drain, scrub and disinfection will clear from the tank.
No travel charge anywhere in Maharani Bagh. The final price is confirmed on the call before we come — it depends only on tank size and access.

We reach every pocket of Maharani Bagh — and there’s no travel charge to any of them:
“Do you clean Sintex tanks in Maharani Bagh near Ishwar Nagar?” Yes. We cover all of Maharani Bagh and the surrounding stretch near Ishwar Nagar, New Friends Colony and Mathura Road. Many of the plastic loft tanks in these kothis have not been opened for months or years, so we allow extra time for the heavier build-up we usually find inside them.
“What does it cost to clean a 500 to 1000 litre Sintex tank here?” A plastic loft tank up to 500 litres starts at ₹699, and a 1000 litre Sintex tank is ₹899. The rate covers draining, clearing the sludge, a plastic-safe wash, hand-scrubbing and a food-grade sanitiser, with photos afterwards. A large kothi often has several plastic tanks, and we give a bulk discount when four or more are done together.
“Can you clean my plastic tank the same day I call?” Usually we can offer same-day or next-morning for Maharani Bagh. A single plastic tank takes about ninety minutes, though a long-neglected one with heavy algae may run over. We will be honest about timing on the call, and your supply returns to normal the same day once the tank refills.
“Why does my Sintex tank in Maharani Bagh go green even when barely used?” Even lightly used plastic tanks here turn green because the walls let sunlight in, and light on still, warm water is all algae need. In these big kothis a loft tank often serves few people, so the water sits and the film has time to spread. Rinsing never removes it; the walls must be scrubbed and disinfected.
“Is pressure washing safe for a plastic tank, and how do you remove algae without scratching it?” Very safe. We wash plastic and Sintex tanks at a pressure set for the material, so there is no cracking or gouging even on an older, sun-brittled tank. Algae is lifted with soft pads, never wire brushes, which scratch the plastic and speed up biofilm return. A food-grade disinfectant then kills the last spores before we refill.
