Sintex & Plastic Tank Cleaning in Alaknanda

Sintex & plastic tanks in Alaknanda

Alaknanda mixes DDA flats, cooperative group-housing societies and the busy Alaknanda market, and the water story here is shared tanks. Whether it is a plastic tank on an individual flat or a bank of Sintex tanks feeding a society block, plastic is everywhere because it is cheap to fit and easy to replace. The catch is that plastic behaves very differently from concrete once algae take hold, and a shared tank feeding many families shows it fast.

Alaknanda runs on DJB with borewell backup, and that borewell water carries enough mineral to scale plastic walls between cleans. If your block also has an underground sump or you want the whole society done together, our general water tank cleaning in Alaknanda page covers every tank. Here, though, we are focused specifically on Sintex and plastic tanks — the overhead tanks that turn green and slimy quickest.

Why Sintex tanks in Alaknanda go green faster than concrete

A concrete society tank is dark inside, but the plastic and Sintex tanks common in Alaknanda let daylight pass straight through the walls. That light is what green algae feed on, and once a film starts it spreads across the whole inner surface. On a rooftop that catches full afternoon sun over the flats, the water warms up too, and warm, lit water in a plastic tank is close to ideal growing conditions for algae and slimy biofilm.

The borewell backup that keeps Alaknanda supplied in summer is the second factor. It brings dissolved minerals that settle as a pale scale on plastic floors and around the outlet, and it also carries sediment that a busy block never lets settle. Add fine dust from the market lanes drifting past loose lids, and a plastic tank builds a gritty, slippery layer far quicker than most residents expect between one clean and the next.

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 Alaknanda customers

“Do you clean Sintex tanks in the Alaknanda DDA flats and near Don Bosco Road?” Yes. We regularly clean plastic and Sintex tanks across the Alaknanda DDA pockets, the group-housing societies near Don Bosco Road and the blocks around Alaknanda market. Whether it is one flat’s loft tank or several society tanks on a shared roof, we can schedule them together in one visit.

“What does it cost to clean a 500 to 1000 litre Sintex tank here?” A single 500 litre plastic loft tank starts at ₹699, and a standard 1000 litre Sintex tank is ₹899. That price includes draining, removing the slimy sediment, a plastic-safe jet wash, hand-scrubbing and a food-grade disinfectant rinse. For a society with several tanks on one block, we give a bulk discount on four or more.

“Can you clean my plastic tank the same day I call?” Usually yes. Alaknanda is close to our regular South Delhi routes, so same-day or next-day slots for a plastic tank are normally available. One standard Sintex tank takes around ninety minutes start to finish, and once it refills your flat is back to normal supply the same afternoon.

“Why does my Sintex tank in Alaknanda turn green and slimy so fast?” Alaknanda tanks are mostly plastic or Sintex, and those walls let sunlight in. Light plus the warmth of a sun-facing roof is exactly what algae need, so a green film returns within weeks if a tank is only rinsed. A shared society tank feeding many flats also refills constantly, which keeps bringing in the spores that let the slime spread.

“Is pressure washing safe for a plastic tank, and how do you remove algae without scratching it?” It is completely safe when done right. We set the jet wash to a pressure meant for plastic, so the Sintex walls are never cracked or gouged. To lift algae we use soft scrubbing pads rather than wire brushes, since wire scratches the surface and gives biofilm somewhere to cling. A food-grade sanitiser then clears the last spores.
