Overhead vs Underground Tank Cleaning

Who cleans the rooftop tank when it feeds both the office downstairs and the flats above? In Jhandewalan that question goes unanswered for years, so KaamGenie steps in to drain, scrub and disinfect these mixed-use overhead tanks. From ₹699.
Jhandewalan is a mixed commercial-office and residential pocket of Central Delhi, home to trade offices, the well-known electronics market and older flats stacked among them. DJB-fed tanks here serve a blend of workplace and residential use, so a single rooftop tank might feed an office pantry and washrooms by day and family kitchens by evening. That constant, varied activity keeps sediment settling in overhead and underground tanks through the day. The mixed use is also the tank's weakness: with offices and homes sharing the building, no one clearly owns the upkeep, so tank cleaning is frequently left unassigned and overdue. Meanwhile the tank fills and drains steadily, folding fresh grit into an ageing interior. Biofilm settles along the walls where routine use never disturbs it. By the time the water clouds, the tank is well past due.
KaamGenie cleans these mixed-use rooftop tanks the proper way: we drain the tank, scoop out the sludge, jet-wash the walls, then hand-scrub the corners and inlet where biofilm collects. A anti-bacterial disinfectant wash goes in before we refill, and before-and-after photos reach your WhatsApp. This is our dedicated page for water tank cleaning in Jhandewalan, focused on the overhead (rooftop) tanks feeding both offices and homes here. We work evening slots so the clean never clashes with office hours, and we coordinate so shared costs split cleanly.
When one rooftop tank serves both an office and the flats above, the responsibility for cleaning it falls between the business and the residents, so it quietly goes years without being opened. All the while the tank fills and drains on DJB supply through workplace and home use combined, and the sediment carried in settles on the floor each still period. Ageing tanks give that grit and biofilm a rough surface to gather on.
Because the upkeep is nobody's clear job, the tank only gets attention once the water visibly clouds or tastes flat, by which point the floor holds real sludge and the walls carry film. A shared mixed-use tank also affects both the office staff and the resident families at once. One coordinated clean on an evening slot, with the cost split, is the sensible fix.
No travel charge anywhere in Jhandewalan. The final price is confirmed on the call before we come — it depends only on tank size and access.

“Our tank feeds an office and flats, who should book the clean?” Any one point of contact can book us and we handle the rest, which is the easiest way past the shared-ownership deadlock. We coordinate the day so both the office and the flats have supply back the same evening, and the cost can be split.
“Can you clean without disturbing office hours?” Yes. We work evening slots so the drain and clean happen after the office winds down. A single tank is done in about ninety minutes to two hours, so everything is back to normal before the next working day.
“What does a mixed-use rooftop tank clean cost?” A standard 500 to 1,000 litre tank starts at ₹699 and up to ₹899. A larger 1,001 to 2,000 litre tank serving both office and flats is ₹1,299 to ₹1,499, and a whole-building clean runs ₹2,400 to ₹3,000.
“How do we know a shared tank is overdue?” If no one can remember it being cleaned, if the water clouds in the morning, or if the taste has flattened, it is overdue. Shared mixed-use tanks are almost always past due precisely because no one owns the job.
“Do you clean the underground tank as well as the rooftop one?” Yes. Many Jhandewalan buildings have an underground sump feeding the rooftop tank, and we can clean both in one visit so the whole line is clear. This page focuses on the overhead tank, but the sump is handled the same way if you need it.
