Overhead Water Tank Cleaning in Nimri Colony (Ashok Vihar)

Overhead tanks in Nimri Colony (Ashok Vihar)

Nimri Colony in Ashok Vihar is a planned DDA pocket, laid out in orderly blocks of flats and independent floors that have aged together over the decades. The overhead tanks serving these DDA structures run on DJB supply and, being older, slowly accumulate sediment and a little scale as the buildings settle into middle age. Many blocks share a rooftop tank across several flats, and that shared ownership is the quiet problem: no single resident feels responsible for climbing up to clean it. So the tank sits, filling and draining daily, while sediment builds on the floor and biofilm creeps along the walls. The ageing concrete and plastic surfaces hold that film more readily than new tanks. Between long intervals of neglect, the deposits deepen until the water clouds or tastes flat. That is usually the moment a resident finally asks around for a cleaner.

KaamGenie cleans these DDA rooftop tanks thoroughly: we drain the tank, scoop out the sludge, jet-wash the scale from the walls, then hand-scrub the corners and inlet a jet cannot fully reach. A anti-bacterial disinfectant wash goes in before we refill, and before-and-after photos come to your WhatsApp. This is our dedicated page for water tank cleaning in Nimri Colony (Ashok Vihar), focused on the overhead (rooftop) tanks these ageing blocks depend on. For a shared tank we can coordinate with all the flats so the cost is split cleanly.

Why shared DDA rooftop tanks in Nimri get neglected

When a single rooftop tank feeds several flats, the upkeep falls between everyone and no one, so the tank quietly goes years without being opened. Meanwhile it fills and drains daily on DJB supply, and the sediment carried in settles on the floor each still night. The ageing DDA concrete gives biofilm a rougher surface to grip, so the walls film over faster than in a newer tank.

Because no resident individually owns the job, the tank only gets attention once the water visibly clouds or the taste flattens, by which point the floor holds real sludge. A shared tank also serves more people, so the water quality issue affects several households at once. Coordinating one annual clean across the flats is the sensible fix, and it splits the cost too.

How we do it — our 6-step process

• 1. Drainage We drain the overhead tank down to the sludge line, saving the clean water where we can.
• 2. Sludge Removal The heavy sediment, mud and settled muck at the bottom is scooped out manually.
• 3. Vacuum Cleaning Industrial wet-vacuums lift the loosened dirt from every corner of the tank.
• 4. High-Pressure Jet A high-pressure jet wash on the walls, floor and ceiling breaks off calcium scale and algae.
• 5. Anti-Bacterial Wash A disinfectant wash kills the remaining bacteria and algae before the tank refills.
• 6. Quality Report Before and after photos are sent to you on WhatsApp.

Common questions from Nimri Colony (Ashok Vihar) customers

“Our block shares one rooftop tank, how does billing work?” For a shared tank we clean it once and the flats split the cost between them. A shared tank of 1,001 to 2,000 litres is ₹1,299 to ₹1,499, and a larger 2,000 to 3,000 litre one runs a little higher. We can send one WhatsApp with the before-and-after photos to everyone.

“Who is responsible for cleaning a shared DDA tank?” In practice no single flat is, which is why these tanks get skipped for years. We make it easy by dealing with whoever books us and coordinating the day so all the flats have supply back the same evening. One resident can arrange it for the whole block.

“How do I know our old tank actually needs cleaning?” If the tank has not been opened in over a year, if the morning water clouds, or if the taste has flattened, it needs a clean. Older DDA tanks build sediment and biofilm steadily, and most in Nimri are well past due.

“Do you clean the concrete DDA tanks differently?” Yes. RCC concrete tanks hold more scale and biofilm on their rougher surface, so we jet them at firmer pressure and hand-scrub the corners hard. If your block has a Sintex tank instead, we drop the pressure and use pads. We match the method to the tank.

“What is the cost for a single flat's own rooftop tank?” If your floor has its own tank, a standard 500 to 1,000 litre one starts at ₹699 and up to ₹899. Only shared or larger tanks move into the higher brackets. We confirm on sight.
