Signs Your Water Tank Needs Cleaning

In many Rajgarh Colony buildings the shared tank is a nineties-era Sintex, one per floor, opened for cleaning only when the water visibly turns. We service the whole building in a single coordinated visit, staggering tanks so no floor runs dry. The building is quoted in bulk, then split across the flats.
Near the Krishna Nagar border, Rajgarh Colony is older established buildings on regular DJB supply, the kind of belt where a nineties-era Sintex tank still sits on each floor. These shared tanks feed several flats per floor and, because the DJB water usually looks clean, they get opened only when it noticeably discolours. That means many go long stretches with no clean at all. Age has told on the plastic, and inside the walls carry a biofilm and a layer of sediment that clear-looking water hides. Since the tank is shared rather than any one flat's, deciding to clean it has never had a clear owner. A single coordinated visit is the practical way to bring these old shared tanks back to standard.
If you only want your own flat's tank and line attended to, our regular water tank cleaning in Rajgarh Colony handles that by itself. This page is for the shared building tanks, the nineties Sintex units feeding several flats per floor, where one survey and a single split invoice beat each flat going it alone. We count the shared tanks across the building and quote them in bulk. The flats then divide one figure rather than booking one at a time.
These tanks only get cleaned when the water visibly turns, and by then the tank has been fouling for a long time. Waiting for discolouration means the sediment and biofilm are already well established before anyone acts, and every flat on the shared tank has been drinking through it. Clean-looking DJB water gives false reassurance while an old Sintex quietly deteriorates inside. Cleaning the shared tanks on a schedule, rather than on sight, is what keeps the whole building's water genuinely safe.
The shared tank drifts because no single flat owns the decision, and the building waits for a visible sign before anyone moves. We take the whole matter off residents. One person shows us the tanks, we survey the shared Sintex units and quote them in a single bulk figure, clean them in a staggered order so no floor loses supply, and hand back one invoice split across the flats. A shared 2,000 to 3,000L tank is around ₹1,500 to ₹2,000, and taking the whole building together saves roughly 15 to 20 percent.
No travel charge anywhere in Rajgarh Colony. The final price is confirmed on the call before we come — it depends only on tank size and access.

“The DJB water looks clean, so why clean the shared tank?” Clear water can still be standing in a nineties Sintex that has not been opened in years, quietly gathering biofilm and sediment on its walls. By the time the water visibly turns, the tank has been fouling for a long while already. A scheduled clean removes what the eye misses for every flat on the tank.
“Can you handle a nineties-era Sintex tank?” Yes. We clean older Sintex tanks routinely and work gently around the aged, more brittle plastic. We clear the settled sediment, scrub the biofilm from the walls and finish with an anti-bacterial wash. If a tank has genuinely reached the end of its life we will say so plainly.
“How does the cost divide between the flats on one tank?” We quote the building's shared tanks as a single bulk figure and split it across the flats that draw from them. A 2,000 to 3,000L shared Sintex tank is about ₹1,500 to ₹2,000. You get one invoice, divided by flat, rather than a separate bill each.
“Will the building lose water during the clean?” No. We stagger the shared tanks so one is cleaned while the others stay in service, keeping every floor supplied throughout. Only the tank being worked on is briefly offline. The rest of the building carries on as normal.
“Do you offer an annual plan so we stop cleaning only when the water turns?” Yes, and that is exactly the habit the annual plan replaces. Instead of waiting for discolouration, it schedules regular cleans of the shared tanks so the building stays ahead of the problem. It runs about 20 to 25 percent cheaper than one-off visits, with the dates held for you.
