Underground sump cleaning in Jawahar Nagar and Kamla Nagar — the below-ground tanks under PG-packed houses and group buildings near DU North Campus that take relentless daily use, bank silt, and rarely get opened. Confined-space safe. From ₹1,499.
A Kamla Nagar PG never really sleeps, and the buildings around Jawahar Nagar and DU North Campus store the water that keeps it running in an underground sump below the plot. Old residential houses here have been rebuilt and stacked for student tenants, and the bigger ones keep ground storage feeding a rooftop tank through booster pumps. The supply is mostly DJB, but the constant occupancy pushes an enormous volume through that one buried tank every day. Sediment carried in the line settles out in the sump and simply banks up under the relentless use. With landlords juggling many tenants and little time, the ground tank is exactly the thing that gets skipped, so grit and biofilm build unchecked.
KaamGenie cleans these buried PG and group-building sumps in full. We open and ventilate the tank, air-test it, pump out the standing water, scoop and wet-vacuum the settled silt, then jet the caked mud and biofilm from the floor and walls before an anti-bacterial disinfectant wash and a clean rinse, with before and after photos sent on WhatsApp. A closed sump can hold stale, oxygen-poor air, so every entry is a confined-space job: we ventilate and air-test first and keep a spotter at the hatch. If the rooftop tanks need doing in the same visit, see our water tank cleaning in Jawahar Nagar (Kamla Nagar); here the focus is the underground sump.
The sump takes the first fill, so the sediment in the DJB line settles to the bottom before the water is pumped up to the tenants. A PG house running kitchens, bathrooms and laundry for dozens of students pushes a huge daily volume through the tank, so the silt bed rebuilds fast. Standing water over that sludge also grows a slick biofilm on the walls between cleanings.
The problem is that the buried sump belongs to no one tenant and rarely to a busy landlord's routine, so it is opened only when the water starts to taste or smell off. Old houses rebuilt in a hurry for student lets often have ground tanks that were never designed to be easily accessed, and a long-sealed one holds foul, low-oxygen air over the sludge. Our crews ventilate and air-test every Kamla Nagar sump before entry and check the walls while it is open.

“We rent to students. Can you clean without disturbing every room?” Yes. We work around your pump timing so the rooftop tank stays topped up while the sump is drained and cleaned, so supply to the rooms keeps running with only a short break. A morning slot before the tenants are up usually works best.
“Why does a PG sump get dirty so fast?” Sheer volume. A house full of student tenants runs water all day, so the sump refills constantly and the sediment it separates out banks up quickly, while the standing water grows biofilm on the walls. Heavy use is exactly why these tanks need more frequent cleaning.
“What are your prices for a house sump here?” Small sumps up to 1,000 litres start at ₹1,499. A typical 1,001 to 2,000 litre house tank is ₹1,799 to ₹2,200, and a larger 2,001 to 5,000 litre tank runs ₹2,500 to ₹3,500. Doing the sump and rooftop tank together is ₹2,000 to ₹2,800.
“Do you provide anything I can show the tenants it was done?” We send before and after photos on WhatsApp after every clean, so you have a clear record of the silt removed and the finished tank to share with tenants or keep for your own upkeep log.
“Can you handle several PG buildings I own in one round?” Yes, and it is usually cheaper that way. If you have more than one building in Jawahar Nagar or Kamla Nagar we can plan them into a single round and apply a bulk rate across the sumps.
