Water Tank Cleaning in Sarojini Nagar

What we see most in Sarojini Nagar

Sarojini Nagar is living through two realities at once. The market roars on — export-surplus stalls, Babu Market’s shops, the food lanes — while around it the old CPWD residential blocks are being progressively emptied and demolished for NBCC’s high-rise redevelopment. The blocks still occupied run the classic arrangement: shared RCC tanks on each stairwell serving the quarters below, NDMC supply, GI risers as old as the colony. Market-side buildings add another layer, mixing shop storage and stall inventories on lower floors with residences above, all off the same stairwell tank.

Redevelopment is the multiplier. Demolition and construction throw fine cement and demolition dust across the whole colony, and it settles into every tank whose lid is open, cracked or simply old — which in blocks awaiting their own redevelopment turn is most of them. Residents describe grey film on stored water and grit at the tap. Tanks here now need cleaning at two or three times the pace of a normal colony, for as long as the construction phase lasts, and the families still in occupation pool per stairwell to keep up.

How long does it take?

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.

Cement dust in the block tanks: cleaning mid-redevelopment

Cement dust is a worse tank contaminant than ordinary dirt — it partially sets on wet surfaces, bonding a grey crust to RCC tank walls and floors that draining will never shift. In the occupied Sarojini Nagar blocks nearest the NBCC work zones, we now do exactly this job weekly: drain the stairwell tank, mechanically scrub the bonded film off the concrete, remove the sludge, pressure-rinse and disinfect. Shared block tanks price at ₹899 for the common 501–1,000L size, split among the stairwell’s quarters. During active demolition phases nearby, we recommend a four-monthly cycle instead of the usual six.

Stairwell pooling in the blocks that remain

With parts of the colony vacated and the rest waiting, official maintenance attention is understandably thin — so the occupied stairwells organise themselves. One family per stairwell collects shares, books us, and grants roof access; we clean the shared RCC tank in one visit and post dated before-and-after photos to the stairwell’s WhatsApp group. For the market-side buildings where stalls store stock below flats, we schedule around market hours — early morning, before the lanes jam — the same discipline we apply at the big commercial strips. Same-day service is available colony-wide if you call before 10 AM.

Common questions from Sarojini Nagar customers

“The NBCC construction has put grey dust in our water. Can it be fully removed?” Yes, but it needs mechanical scrubbing — cement dust bonds to wet RCC walls and won’t rinse out. We scrub the crust off, remove all sludge, and disinfect. Near active work zones we suggest cleaning every four months until the construction phase passes.

“Our block is due for redevelopment eventually. Is it worth cleaning the tank now?” If families are living there, yes — you’ll drink from that tank every day until handover, which is often years away. A ₹899 clean split across a stairwell costs each quarter very little for clean water in the meantime.

“Can you clean tanks on the market-side buildings without disturbing the shops?” Yes. We work Sarojini Nagar market buildings in the early-morning window before stalls set up, finishing before the lanes fill. The shop or stall owner and the resident families coordinate access with us once, and we keep the same slot each cycle.
