Sintex & Plastic Tank Cleaning in East of Kailash

Sintex & plastic tanks in East of Kailash

East of Kailash mixes DDA flats and independent kothis near Greater Kailash and Kalkaji, and here water is usually stored per floor. Each floor tends to have its own plastic or Sintex overhead tank on the roof, with shared underground sumps per plot below. Because every family manages its own tank, the plastic ones often get topped up and forgotten. That suits a busy household, but a forgotten plastic tank in the sun is precisely where algae quietly take over.

The colony runs on DJB with borewell backup, and that backup water leaves scale on plastic between cleans. If your plot’s shared underground sump also needs doing, or you want every floor’s tank handled in one visit, our full water tank cleaning in East of Kailash page covers it. This page is specifically about Sintex and plastic tanks, the per-floor overhead tanks that turn green and slimy first.

Why per-floor plastic tanks in East of Kailash go green

With a separate plastic tank for each floor, the tanks on an East of Kailash roof sit in full sun with nothing shading them. Light passes through the plastic walls, and that is exactly what green algae feed on. The rooftop heat keeps the water warm well into the evening, so the growing conditions barely let up. A concrete tank would stay dark and cooler inside, but these Sintex and plastic tanks light up and warm through, so a green film forms fast.

The second factor is how these tanks are used. Each floor fills its own plastic tank and rarely opens it, so scale from the borewell backup and a soft layer of settled dust build up unseen. The mineral load leaves a pale crust on the plastic floor, and around the outlet slime clings to it. Because nobody inspects inside until the water tastes off, the biofilm and sediment quietly thicken until a full drain and scrub becomes necessary.

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 East of Kailash customers

“Do you cover Sintex tank cleaning in East of Kailash C and D blocks?” Yes. We clean plastic and Sintex tanks across all of East of Kailash, including A, B, C and D blocks and the houses near Lala Lajpat Rai Marg and Kailash Colony. Whether it is one floor’s tank or every tank on a plot, we can schedule them in a single 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 per floor is ₹899. That includes draining, sediment and slime removal, a plastic-safe wash, hand-scrubbing and a food-grade disinfectant rinse. When several floors’ tanks on one building are done together, we give a bulk discount on four or more.

“Can you clean my plastic tank the same day I call?” Usually yes. East of Kailash sits on our regular South Delhi routes, so same-day or next-morning slots are commonly available. A single Sintex tank takes about ninety minutes, and once it refills that floor is back to normal supply the same day, with photos sent to you afterwards.

“Why does my per-floor Sintex tank in East of Kailash keep going green?” Because each floor’s plastic tank sits unshaded on the roof, sunlight passes through the walls and warms the water, and light plus warmth is what algae need. These tanks are often filled and forgotten, so the film has time to spread. Rinsing will not shift it, which is why the green, slimy layer keeps returning until the tank is scrubbed.

“Is pressure washing safe for a plastic tank, and how do you remove algae without scratching it?” Yes, at the right pressure. We jet-wash Sintex and plastic tanks at a setting made for the material, so the walls are never gouged or cracked. Algae comes off with soft pads rather than wire brushes, which would scratch the plastic and let biofilm grip again. A food-grade sanitiser finishes the clean without harming the tank.
