Sintex & Plastic Tank Cleaning in Daryaganj

Sintex & plastic tanks in Daryaganj

Daryaganj is an old mixed residential and commercial belt on the edge of the walled city, known for its ageing mansions, publishing houses and Sunday book market. The rooftop stores on these older buildings include plastic and Sintex tanks that are often decades old, holding sediment and scale as they age on the DJB supply. Being translucent, the plastic lets terrace sun through the wall to warm the water and feed algae and biofilm. Dust off the busy road drifts into loose lids and settles as grit. A concrete tank would keep the light out, but the plastic ones let it in, so the inside greens quietly. Split residential-commercial ownership means the rooftop tank often lacks a clear caretaker, so cleaning is repeatedly postponed. Left alone, the old plastic tanks coat up well before anyone checks.

We clean these ageing plastic tanks gently and fully: check the body and lid, drain, hand-scoop the slimy sediment, wet-vacuum the base and jet-wash at a plastic-safe pressure. The algae film lifts with soft pads rather than wire brushes, and we finish with an anti-bacterial disinfectant wash and send before and after photos. If the building's underground store or an old RCC tank also needs doing, see our full water tank cleaning in Daryaganj. This page is specifically about Sintex and plastic tanks.

Why old plastic tanks in Daryaganj are left too long

The plastic wall greens the tank quietly. A Sintex tank on a Daryaganj mansion is translucent, so terrace sun passes through and warms the water, and that warmth is what algae and biofilm need. A concrete tank blocks the light and stays cooler, holding up longer, while the exposed plastic one greens on the inside where nobody sees it. Because the fouling is out of sight, the tank looks fine from the roof even as the film spreads, so it is left far too long.

Split ownership is the other reason. When a building mixes shops below with residence or offices above, the rooftop tank belongs to no one clearly, so its cleaning is repeatedly postponed. The tanks themselves are often decades old, holding accumulated sediment and scale, and road dust drifting in through loose lids adds more grit for the algae to grip. Left between long intervals, an old plastic tank in Daryaganj coats up heavily, so a full drain and plastic-safe scrub is what restores it.

How we do it — our 6-step process

• 1. Drainage We check the tank and lid, then drain it down, saving the clean water where we can.
• 2. Sludge Removal The settled grit and slimy layer at the bottom are scooped out manually.
• 3. Vacuum Cleaning Industrial wet-vacuums clear the loosened dirt from every corner of the plastic tank.
• 4. High-Pressure Jet A jet wash at a pressure safe for plastic cleans the walls, floor and ceiling.
• 5. Anti-Bacterial Wash A disinfectant wash kills remaining bacteria and algae spores.
• 6. Quality Report Before and after photos are sent to you on WhatsApp.

Common questions from Daryaganj customers

“Our building is part shop, part residence, who books the tank clean?” Any one party can book, and it is worth agreeing between the shop and the floors above, because a shared rooftop tank affects everyone's water. We clean it on one visit and send photos so all parties can see the result.

“The plastic tank is decades old, is it still cleanable?” Yes. Old plastic tanks hold more accumulated sediment and scale, but we clean them the same careful way, and if we spot a crack or a failing lid during the check we tell you so you can decide on a repair.

“How much to clean an old rooftop plastic tank in Daryaganj?” A Sintex up to 500 litres starts at ₹699 and a standard 1000L is ₹899. Larger 1000 to 2000L tanks are ₹1,299 to ₹1,499, with a bulk per-tank rate for more than one tank.

“The tank looks fine from the roof, does it need cleaning?” Often yes. Plastic tanks green on the inside where you cannot see them from outside, so the tank can look fine while a film spreads within. We open it, show you photos of the interior, and clean whatever we find.

“Can you clean without disturbing the shop trading below?” Yes. We work on the terrace and time the drain to your water-supply hours, so the shop below carries on and the tank is refilled before anyone needs it.
