Sintex & Plastic Tank Cleaning in Gulmohar Park

Sintex & plastic tanks in Gulmohar Park

Gulmohar Park is a leafy, affluent colony of kothis and builder floors near Hauz Khas and Green Park. Water is stored in individual rooftop overhead tanks and plot-level underground sumps, and those rooftop tanks are usually plastic or Sintex. Even the large trees that give the colony its character do not shade the rooftops, so the plastic tanks sit in open sun for most of the day. That open, sunlit position is exactly what lets algae get going inside a plastic tank.

Supply is mainly DJB with some borewells, and where a borewell runs it leaves mineral scale on the plastic between cleans. If your plot’s underground sump also needs attention or you want every tank handled together, our fuller water tank cleaning in Gulmohar Park page covers it. This page focuses specifically on Sintex and plastic tanks, the rooftop overhead tanks that turn green and slimy soonest here.

Why plastic tanks in Gulmohar Park grow algae faster than concrete

The individual plastic tanks on Gulmohar Park roofs catch full sun despite the colony’s greenery, and daylight passing through their walls is what green algae feed on. The rooftop heat keeps the water warm into the evening, extending the growing hours. A concrete tank stays dark and cool inside and slows any bloom, but Sintex and plastic light up and warm through, so a green film forms across the walls well before residents expect to see it after a clean.

Usage patterns add the rest. In many of these homes a small household draws only lightly on a decently sized tank, so the water sits rather than turning over, giving algae time to spread. Where a borewell supplements supply, its minerals settle as a pale scale on the plastic floor, and dust drifts in through lids that no longer seal on older tanks. Left between infrequent cleans, that scale and the biofilm combine into a slippery, gritty coating.

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 Gulmohar Park customers

“Do you clean Sintex tanks in Gulmohar Park near SDA and Yusuf Sarai?” Yes. We cover all of Gulmohar Park and the surrounding stretch near SDA Market, Yusuf Sarai and Aurobindo Marg. Whether it is a single kothi’s rooftop plastic tank or several tanks on a builder floor, we can usually arrange a visit within the same week and clean them in one go.

“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. That covers draining, sediment and slime removal, a plastic-safe wash, hand-scrubbing and a food-grade disinfectant rinse, with before and after photos. Where a building has several plastic tanks, we give a bulk discount on four or more.

“Can you clean my plastic tank the same day I call?” Usually yes. Gulmohar Park is close to our regular Hauz Khas and Green Park routes, so same-day or next-day slots are normally available. A single Sintex tank takes about ninety minutes, and once it refills your home is back to normal supply the same day, with photos sent afterwards.

“Why does my Sintex tank in Gulmohar Park keep turning green?” Gulmohar Park’s rooftop tanks are plastic, and even with the colony’s trees they sit in open sun, so light passes through the walls to feed algae. In smaller households the water also sits still, giving the film time to spread. Rinsing will not remove it, so the green, slimy layer keeps returning until the walls are scrubbed and disinfected.

“Is pressure washing safe for a plastic tank, and how do you remove algae without scratching it?” Yes. We wash Sintex and plastic tanks at a pressure set for the material, so the walls are never gouged or cracked, even on an older tank. To remove algae we use soft pads, never wire brushes, since wire scratches the plastic and gives biofilm a grip. A food-grade sanitiser then clears the last spores before refilling.
