Underground sump cleaning in Tigri, the colony and DDA-flat cluster near Khanpur and Sangam Vihar. We desilt and disinfect ground sumps that fill fast with sediment, rust and algae from mixed supply. From ₹1,499.
Tigri is a colony and DDA-flat cluster near Khanpur and Sangam Vihar, with plotted houses, resettlement blocks and small apartment buildings. Piped DJB supply is limited, so borewells and tankers fill much of the gap, keeping the water hard with high TDS. That mixed supply is stored first in a ground-level sump or underground tank before being pumped to the rooftop tank, and the intermittent, multi-source refilling drives quick sediment, rust and algae buildup at the bottom.
As the lowest point in the system, the sump takes the first fill and collects more debris than the tank above; cleaning it keeps the whole supply fresher. Pair it with our water tank cleaning in Tigri to clear the sump and rooftop tank together. Our crew ventilates and air-tests every sump as a confined space before entry.
Tigri homes switch constantly between borewell and tanker water, and that mixed, intermittent supply never lets the sump settle to a clean fill. Borewell water brings hardness and iron that leaves rust, tankers add sediment, and the standing water at the base encourages algae, so the underground sump fouls quickly.
We often open a Tigri sump to find grey sludge streaked with rust and green algae along the waterline. We pump out the standing water, scoop the sludge, jet-wash the caked mud, rust and scale, hand-scrub the foot-valve area, then disinfect with a food-grade solution and inspect the RCC for cracks and seepage.
No travel charge anywhere in Tigri. The final price is confirmed on the call before we come — it depends only on tank size and access.

We reach every pocket of Tigri — and there’s no travel charge to any of them:
“Do you clean tanker-fed sumps in Tigri’s DDA flats and village?” Yes, tanker-fed sumps across Tigri village, the DDA flats and Tigri Camp are common work for us. Tanker water often arrives with suspended sediment that settles straight into the sump, on top of borewell silt and rust. We pump out, scoop, jet-wash and disinfect so the stored water is clean again. Homes on mainly tanker supply should clean more often.
“What does a 2000L kothi sump clean cost in Tigri?” A standard 2000L underground sump starts at ₹1,499. Because Tigri water mixes borewell and tanker supply, sumps often hold heavy sediment, rust and algae, which can affect the time, so we confirm the rate after inspecting. There are no hidden charges. Doing the rooftop tank in the same visit saves money.
“My sump has rust and algae — can you clear both?” Yes, both are common in Tigri sumps because of the hard, intermittent supply. We scrub and jet-wash the rust and algae off the walls and floor, then disinfect with a food-grade solution that kills the biofilm. The cleaned sump gives clearer, fresher water. Regular cleaning keeps rust and algae from returning fast.
“Is confined-space sump entry safe?” Yes. We treat every sump as a confined space, opening, ventilating and air-testing before anyone enters, and never going into an unventilated sump. This careful routine matters in the dense Tigri blocks. A trained, equipped crew keeps the work safe.
“Do you check Tigri sumps for cracks?” We do. After the sludge, rust and algae are cleared and the walls are washed, we inspect the RCC for cracks and seepage, common in the older sumps near Khanpur and Sangam Vihar. We photograph any damage so you can seal it. Fixing cracks early keeps dirty groundwater from leaking into your clean supply.
