Underground sump and ground-tank cleaning in Dashrath Puri — where iron-rich borewell water stains tank walls orange, rusts the steel around it, and leaves a rust-and-silt sludge in the first tank it touches. Confined-space safe, photo-documented. From ₹1,499.
Dashrath Puri is a compact, family-owned colony on the Dabri–Palam road — tight lanes of 3-storey homes, most with a rental floor, and its own Magenta Line station. Its water signature is iron. The borewell supply carries enough of it to stain the paired rooftop tanks orange and rust their steel stands, and the same chemistry works harder below ground: in the sump or ground storage tank that takes the first fill, iron oxidises and settles into a distinctive rust-brown sludge, mixed with the sand the borewell brings up.
KaamGenie clears that iron load at its source — we pump the sump down, scoop and wet-vacuum the rust-and-silt bed, jet-wash the stained walls, and finish with a food-grade disinfectant rinse, photographing the before and after so you can see the orange gone. The stained rooftop pair upstairs is handled by our water tank cleaning in Dashrath Puri — this page is for the buried tank where the iron settles first.
Dissolved iron is invisible when the water arrives, but the moment it meets air in a storage tank it oxidises into the orange particles that stain everything they touch. The sump, taking the first fill and holding it longest, is where most of that oxidation happens — so the bed here is not ordinary grey silt but a dense rust-brown sludge that marks walls, clogs pump strainers and gives water a metallic edge. Left alone it also feeds iron bacteria, the slimy orange growth that makes tanks smell swampy.
The colony’s building pattern concentrates the problem: family homes with a rental floor mean steady daily draw through modest tanks, so the chain cycles constantly and the iron keeps arriving. Cleaning the roof pair without the sump just re-stains them within a month. Our recommendation for Dashrath Puri is simple — do the whole chain annually, sump first, and the orange stays gone the rest of the year.

“Can you remove the orange staining inside our tank?” Mostly, yes. Jet-washing and scrubbing shift the loose iron deposit and much of the staining; long-set stains may leave a shadow in the plastic or plaster, but the surface comes clean and hygienic. More importantly the rust sludge on the floor — the part that actually moves into your water — is removed completely.
“What does it cost in Dashrath Puri?” From ₹1,499 for a sump or ground tank up to 1,000 litres. Most Dashrath Puri first tanks fall in that band; larger ones run ₹1,799–2,200 up to 2,000 litres. Cleaning the paired rooftop tanks in the same visit earns a combined rate — sensible here, since the iron re-stains a half-cleaned chain fast.
“Our water smells metallic — will cleaning fix it?” It will remove the biggest contributor: the oxidised iron sludge and any iron-bacteria growth in the tank. The dissolved iron still arriving from the borewell will remain — that needs an iron-removal filter if you want it gone entirely — but most households find taste and smell improve sharply once the tanks stop adding accumulated rust to the fresh supply.
“Do you cover the lanes near Dashrath Puri metro same-day?” Usually — call before 10 AM and we can typically slot you into that day’s Dabri–Palam run. The colony’s tight lanes are familiar territory; the crew parks where possible and runs hoses in.
“Is the rust sludge harmful to health?” Iron itself is more a taste and staining nuisance than a toxin at these levels, but the sludge bed it forms is an ideal habitat for bacteria and biofilm, and iron bacteria give water a genuinely unpleasant smell. That is why we finish with a food-grade disinfection rather than stopping at rust removal — the goal is a hygienic tank, not just a less orange one.
