Overhead vs Underground Tank Cleaning

Noor Nagar — the dense family quarter between Jamia Nagar and the Okhla railway line, where the classic roof carries a pair of 500L tanks on steel stands that rust as fast as the borewell water scales. We clean the tanks and check the stands, from ₹699.
Noor Nagar is a colony of family-owned homes grown vertical — three and four storeys with married siblings on separate floors, one shared roof above them all. The signature setup is a pair of 500L tanks side by side on fabricated steel stands, one tank per branch of the family or one for each supply source. The borewell water running through them is high-TDS, so the tank interiors scale white while the stands beneath them do something worse: they rust, and the flakes fall exactly where the wind carries them — including through any gap in the lids below.
Inside the tanks we find a distinctive Noor Nagar mix: hard mineral scale on the walls and a base layer of settled scale grit spiked with rust flakes, some from the stands, some from ageing GI fittings. The extension side and the lanes toward the railway line have the older stands and the worse rust. Because the homes are owner-occupied, the fix sticks once made — families here maintain what they own — but someone has to open the tank and show them what’s in it first.
For a standard 1000-litre overhead tank, the whole job takes about 90 minutes from doorbell to pack-up. Underground sumps take longer — usually 2 to 2.5 hours depending on sludge. You don’t need to provide anything: we bring our own water for the rinse, vacuums, jet pumps, food-grade disinfectant and gloves, and send before/after photos on WhatsApp.
The paired-tank roof is Noor Nagar’s standard, and we clean it as a pair — ₹699 per tank, both drained, de-scaled with jets and scrub pads, cleared of the rust-and-scale grit at the base, and disinfected with food-grade chemicals in a single visit of around two and a half hours. While the tanks drain we inspect the steel stands underneath at no charge: surface rust means a wire-brush and paint job for your local welder; section rot means the stand needs work before it needs to hold a tonne of water again.
Noor Nagar’s homes often house one extended family across the floors, which should make tank cleaning easy — but shared ownership can stall decisions just as thoroughly as absentee landlords do. In practice one brother books, we clean both tanks and the shared pipework connections, and the photos land on the family group where everyone can see the before-and-after. No split-billing drama, no waiting for a family meeting: the ₹1,398 for a typical twin-tank roof settles itself.
“There are rust flakes in our water in Noor Nagar — is the tank or the pipe to blame?” Usually both contribute, and the clean tells us which dominates. We remove all the rust-and-scale grit from the tank base, then check whether the inlet fittings or the stand are actively shedding. You get photos of the culprit so you fix the actual source, not just the symptom.
“What does cleaning both tanks on our roof cost?” ₹699 per 500L tank, so ₹1,398 for the standard Noor Nagar pair, cleaned back-to-back in one visit. If one of your tanks is the larger 501–1,000L size it’s ₹899 for that unit. Same-day if you call before 10 AM.
“Do you check the tank stands, and is that extra?” We inspect the stands free with every Noor Nagar clean, because rusting steel stands are this colony’s particular weak point. You get photos and a plain verdict — repaint, reinforce or replace — to take to your welder.
