Scheduled sump-and-tank service for Ishwar Nagar — the quiet Mathura Road colony where settled homes book preventive annual cleans through the colony round, with old GI-pipe rust scrubbed out and documented. From ₹1,500 per tank.
Ishwar Nagar is a small, quiet colony on Mathura Road opposite the Friends Colony flank — older independent houses, a Baha’i-adjacent institutional belt, and a scattering of rebuilt builder floors. DJB supply here is steadier than the Okhla side a kilometre away, and homes run the classic settled setup: a modest sump, a pump, and rooftop tanks. The colony’s water problem is quieter too, and older — GI inlet pipes laid decades ago shedding rust into tank bottoms year after year.
KaamGenie serves Ishwar Nagar the way a settled colony prefers: a scheduled annual or twice-yearly service covering sump, pump check and rooftop tanks, booked home by home or through a colony round where the RWA circulates one date and every participating house gets the bulk rate. We scrub out the rust sediment the GI pipes deposit, photograph what we find so owners can plan pipe replacement, and leave a dated certificate for the house file.

Because the water here is decent and the colony is calm, nothing forces the issue — no tanker grit, no borewell crust, no tenant complaints. But forty-year-old GI inlet pipes corrode from the inside, and every fill carries a fine rust load that settles silently in the sump and the tank bases. Owners see slightly tea-coloured first-draw water on some mornings and think nothing of it; the sediment bed underneath grows for years.
Preventive service is cheap insurance in a colony like this: one visit a year — sump scooped, tanks at ₹1,500 each descaled and disinfected, pump checked — keeps the rust bed from ever reaching the outlet, and our photos track the pipe corrosion so replacement happens on the owner’s schedule, not the pipe’s. The colony-round model suits Ishwar Nagar’s size perfectly: one date, several homes, bulk rate for all, and the institutional properties on the belt can book the same round for their larger systems.
No travel charge anywhere in Ishwar Nagar. The final price is confirmed on the call before we come — it depends only on tank size and access.

We reach every pocket of Ishwar Nagar — and there’s no travel charge to any of them:
“What does the annual home service cover in Ishwar Nagar?” One visit covering the sump — drained, silt scooped, walls jetted — the rooftop tanks at ₹1,500 each with a multi-tank discount, a pump and float check, and food-grade disinfection throughout. You get before-and-after photos and a dated certificate for the house file, plus our note on pipe and fitting condition.
“How does the colony round work?” The RWA or any resident circulates a date; homes opt in, and our crew works through the colony over one or two days. Every participating home pays the bulk rate rather than the solo rate, and each gets its own full documentation. Small settled colonies like Ishwar Nagar are where this model works best.
“Our first-draw water is sometimes brownish. Is that the tank?” It is usually the old GI inlet pipe shedding rust overnight, which then settles in your tank and sump. Cleaning removes the accumulated bed so it stops concentrating, and our photos show you the corrosion level — several Ishwar Nagar homes have used them to decide when to replace the inlet run with CPVC.
“Can the institutional properties on the belt book the same service?” Yes. Institutional buildings run bigger sumps and tank banks but the service is the same chain — sump, pumps, tanks — quoted after a survey, with the documentation their administration needs for records. They can join the colony round date or take a dedicated visit, whichever suits their calendar.
“Do you do urgent visits, or only scheduled ones?” Both. Scheduled service is the Ishwar Nagar norm, but call before 10 AM and we can usually manage a same-day visit for anything sudden — a foul smell, visible rust flakes at the tap, or a sump issue. Mathura Road access makes the colony one of our quickest reaches in the south-east.
