How Often Should You Clean Your Water Tank?

Harsh Vihar marks the seam where the Karawal Nagar builder floors run up against the Mandoli units, a belt of rented storeys where the ground reservoir belongs to no one in particular. Very hard water rusts its base and chokes the booster pump, and a full clean starts at ₹1,499.
This fringe pocket, self-built storeys and small blocks pressed against the industrial edge, lives almost wholly on hard, iron-bearing water topped up by tanker, with piped supply barely present. Each building banks that water in a ground reservoir, then a booster raises it to the plastic rooftop tanks. What defines Harsh Vihar is tenancy: storeys let and re-let, so the reservoir downstairs is nobody's settled charge and simply stays shut. Meanwhile the iron in the water leaves a rust bloom across the base that thickens month on month.
We take the reservoir back to a clean base: force air and check it, draw the water down, lift the rusty deposit and rub back the ring, vacuum, pressure-rinse and finish with a anti-bacterial sanitiser. Buildings that also want the rooftop tanks handled can see our water tank cleaning in Harsh Vihar. This page is about the below-ground reservoir, the vessel the whole building depends on and no tenant claims.
Two things run together here. The iron-bearing water blooms rust across the base and a hard ring up the sides, and the letting culture means no single household treats the shared reservoir as theirs. So the deposit is left to build while tenants come and go, and the odd trace of grit off the neighbouring units settles on top. The vessel can sit a year or more without its lid ever coming off.
The cost surfaces at the booster. A thick deposit and rust bloom foul the intake, so pressure to the rooftop tanks fades even with water in the reservoir, and the same matter rides up to give the supply a rusty edge. On a rented seam like this the complaint gets handed on rather than acted on. Clearing the reservoir restores the flow and settles the question of whose job it was by simply getting it done, with a photo record for owner and tenant alike.
No travel charge anywhere in Harsh Vihar. The final price is confirmed on the call before we come — it depends only on tank size and access.

“Pressure to our rooftop tanks keeps fading. Could the reservoir be behind it?” Very likely. A rust bloom and thick deposit foul the booster intake, so the flow weakens even with water in the reservoir. Lifting the deposit and rubbing back the ring usually restores the pressure, and we check the intake while we are in there.
“The storeys are all rented and no one owns the tank. Who can book the clean?” Any occupant can. We need the lid opened and permission to enter, and we send the photo record to both the tenant who called and the owner, so the shared reservoir finally gets seen to.
“There is a rust bloom on the base. Can you take it back?” Yes. We lift the rusty deposit off the base and rub the hard ring back off the sides, then sanitise. Iron still dissolved in the water would need a filter, but clearing the bloom stops the reservoir feeding rust up to the taps.
“What does a Harsh Vihar reservoir clean cost?” From ₹1,499 for up to 1,000 litres, priced by capacity. Most storeys here hold a vessel in the smaller bands; we confirm on sight.
“How often should a let building on this seam clean the reservoir?” About yearly, sooner if the booster is already fading or the water is drawing rusty, because the iron bloom rebuilds fast on very hard supply. Fixing a repeat date stops it slipping between tenancies.
