Society & RWA Tank Cleaning in Friends Colony

Society & RWA tanks in Friends Colony

Friends Colony, East and West, is one of Delhi’s most exclusive addresses — very large independent kothis sitting on big plots near New Friends Colony and Jamia. Each house tends to have its own oversized overhead tank and a deep underground sump, many drawing on private borewells alongside DJB. Because the plots are huge and the sumps old, water can sit for a long time in tanks a single family barely draws down, going stale and silting up out of sight.

This is a colony of individual houses rather than a block-of-flats society, but the Friends Colony RWA can line up a whole-street round, and several kothis with staff quarters or guest annexes run shared tanks of their own. For one house, start with our general water tank cleaning in Friends Colony page. This page is specifically about society and RWA (whole-building) tank cleaning, doing every shared tank on a plot in one visit.

Why RWAs and large plots in Friends Colony should clean tanks every 3–4 months

On these big plots the underground sump is deep and old, holds a lot of water, and takes the first borewell and DJB fill, so it collects sediment faster than anyone would guess. From the sump water is pumped up to large rooftop tanks that a small family only lightly uses, letting it stand and stagnate. Within three to four months the standing water and settled silt breed bacteria, and there is no filter after these tanks to catch it.

Because the houses are staff-run and the tanks out of sight, cleaning is easy to postpone, and an old sump can go many years unopened. Booking through the RWA lets several plots be done on one day at a bulk rate, rather than each caretaker arranging it alone. An annual AMC with quarterly visits keeps the big sumps and rooftop tanks documented, which matters when a house is rented to a company or diplomat.

How we do it — our 8-step process

• 1. Site survey & schedule We count the tanks, check access and the water-supply timing, and agree a slot that doesn’t cut off the building.
• 2. Isolate & drain Each tank is isolated and drained in turn so supply to flats is disrupted as little as possible.
• 3. Sludge & sediment removal Settled sludge is scooped and wet-vacuumed from every overhead and underground tank.
• 4. High-pressure jet wash Walls, floor and ceiling of each tank are jet-washed to remove scale and biofilm.
• 5. Manual scrub Corners, joints and inlet/outlet mouths are hand-scrubbed across all tanks.
• 6. Anti-bacterial treatment A food-grade disinfectant wash sanitises every tank before refill.
• 7. Refill & supply check Tanks are refilled and we confirm supply to the flats is back to normal.
• 8. Photos & RWA certificate Before/after photos of each tank and a dated certificate for the society’s maintenance file.

Common questions from Friends Colony customers

“Do you cover the large kothis and staff blocks in Friends Colony East and West?” Yes. We clean the big overhead tanks and deep underground sumps on the kothis across Friends Colony East and West, including staff annexes and guest blocks that share tanks. We coordinate with the caretaker or the RWA, do every tank on the plot in one visit, and give a dated certificate.

“What does it cost for a large plot here?” A shared overhead tank of 2,000 to 3,000 litres is ₹1,500 to ₹2,000, and the big underground sumps here are quoted by capacity, as they hold well above the usual size. Doing all the tanks on a plot or several houses together earns a 15 to 20 percent bulk discount. We confirm on site.

“Can one household book without waiting for the RWA?” Yes. Most cleaning here is arranged house by house, so there is no need to wait. Call 95603 66362 for your own kothi’s overhead tank and sump, or ask a few neighbours and we will do the street together at a bulk rate on the same day.

“How do you clean without leaving the house without water?” We time the visit around your borewell and DJB fill, drain and clean the rooftop tank first, then pump out and clean the sump, refilling as we go. On a big plot with a sump and rooftop tanks, at least one part stays in supply, so the household is never fully without water.

“Is an AMC available for these houses?” Yes. A four-visits-a-year AMC covers every overhead tank and sump on the plot and runs 20 to 25 percent below single visits. After each round we issue dated before-and-after records, which owners here often need when the house is leased to a company or embassy.
