Sintex & Plastic Tank Cleaning in Sriniwaspuri

Sintex & plastic tanks in Sriniwaspuri

Sriniwaspuri is a colony of DDA flats near Kalkaji and Ashram, where water comes off society overhead tanks feeding whole blocks, with plot-level underground sumps below. On the rooftops those block tanks are usually plastic or Sintex, each serving many flats at once. A tank feeding a full block is refilled steadily all day to keep everyone supplied, and it sits in open sun on the flat roof. That combination of a shared, sunlit plastic tank is exactly where algae find the light they need to take hold.

The colony runs on DJB supply, and the fine silt it carries settles on plastic floors between cleans. If your block also needs its underground sump done or you want the whole society handled at once, our general water tank cleaning in Sriniwaspuri page covers it. This page is specifically about Sintex and plastic tanks — the shared block overhead tanks that go green and slimy first.

Why shared Sintex tanks in Sriniwaspuri go green quickly

The plastic block tanks on Sriniwaspuri rooftops sit in open sun above the DDA flats, and light through their walls is what green algae feed on. Serving a whole block, the water stays lukewarm from constant use and the rooftop heat, which extends the growing hours well into the evening. 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.

Sediment and dust finish it. The DJB supply carries a fine silt that settles on the plastic floor, and around the outlet a scale ring traps slime. Near the busy Ashram and Kalkaji roads, dust drifts in through lids that no longer seal on older block tanks. Because a shared tank feeding many flats is refilled several times a day, the silt never settles out for removal, so the sediment and biofilm build into a slippery, gritty layer between cleans.

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 Sriniwaspuri customers

“Do you clean Sintex tanks in the Sriniwaspuri DDA flats?” Yes. We cover all of Sriniwaspuri, including the DDA flat blocks and the pockets near Kalkaji, Ashram and Maharani Bagh. Whether it is a single flat’s plastic tank or a shared block tank on the roof, we can schedule them together and clean them in a single visit for the society.

“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 block tanks gets a bulk discount on four or more done together.

“Can you clean my plastic tank the same day I call?” Usually yes. Sriniwaspuri is close to our regular Kalkaji and Ashram 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 Sriniwaspuri keep going green?” Sriniwaspuri’s block tanks are plastic and sit in open sun, so light passes through the walls to feed algae while constant use keeps the water warm. A shared tank feeding many flats 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.
