At the metro's terminal end near the Delhi-UP border, Dilshad Garden's DDA pockets and CGHS societies run shared sumps and rooftop tanks that serve many families at once. KaamGenie cleans the overhead tanks that sit at the top of that chain. From ₹699.
Dilshad Garden is a planned world of its own: labelled DDA pockets, neat flat blocks and cooperative CGHS societies laid out near the metro terminus and GTB Hospital. The typical setup here is group housing, an underground sump filling from DJB, then pumps lifting that water to rooftop overhead tanks that feed a whole block of families. Because the storage is shared and RWA-managed, the cleaning falls on a committee rather than a single owner, and committees stretch the cycle. Half-yearly on paper often slips to yearly in practice, and the overhead tanks accumulate biofilm and sediment in the meantime.
For a society block we clean the rooftop bank methodically: drain each overhead tank, remove the settled matter, jet and scrub the walls, disinfect with a hygienic solution and refill, all logged so the RWA has a record. Before-and-after photos go to the committee for their file and their residents. This overhead page works alongside the broader water tank cleaning in Dilshad Garden, and because the sump feeds these tanks, most blocks sensibly do both together. We schedule around the society's pump hours so supply is barely felt.
Shared responsibility is the reason. When a rooftop tank serves a dozen flats, no single resident feels the urgency to push for a clean, and the RWA has a dozen other jobs competing for the maintenance budget. The tank keeps working, so it stays out of sight and out of mind, quietly gathering a fine sediment on the base and a biofilm along the waterline. The half-yearly interval that group housing really needs quietly becomes an annual one, or longer.
Because these overhead tanks sit downstream of a sump, they receive whatever the sump passes up, so any silt in the reservoir ends up in the rooftop tanks too. Biofilm at the shared waterline can carry through to many families' kitchens at once, which is why the cadence matters more in group housing than in a single home. Sediment also wears the society's pumps and valves, a shared cost the RWA feels. Keeping both sump and overhead on a steady cycle protects every flat on the block at once.
No travel charge anywhere in Dilshad Garden. The final price is confirmed on the call before we come — it depends only on tank size and access.

“How do you handle a full society rooftop bank of tanks?” We clean them as a set in one visit: each overhead tank is drained, cleared, scrubbed, disinfected and refilled in turn, and we log every tank for the RWA. Doing the whole bank together means the block's supply is interrupted just once. We give the committee a single consolidated report with photos of each tank.
“Should the CGHS society clean the sump and overhead tanks at the same time?” It makes the most sense. The rooftop tanks are fed by the sump, so cleaning one without the other leaves half the chain dirty and lets sediment travel straight back up. We do both in a single scheduled visit, which is cheaper and interrupts the block's water only once. Most Dilshad Garden societies book them as a pair.
“What paperwork does the RWA get for its records?” The committee receives before-and-after photos listing each tank cleaned, the date and the disinfectant used, plus before-and-after photos of every tank. It is exactly what an RWA needs for its maintenance file and to show residents the work was done. We can also set a reminder for the next due date.
“How is a shared society tank priced compared with a single home tank?” Society and RWA tanks are priced from ₹1,500 per tank because of their larger capacity, and a bulk rate applies when several are done together, which is normal for a block. A single household overhead tank starts lower at ₹699. For group housing we quote per tank once we know the sizes and number on the roof.
“Can you work around our fixed pump and supply hours?” Yes. We schedule the clean for the window between pump cycles so residents feel the least disruption, and we can split a large bank across a morning so at least one tank always holds water. Tell us the society's supply timings and we will build the visit around them.
