RWA Guide: Society Water Tank Cleaning in Delhi
A practical runbook for committees — inventory, vendor selection, scheduling, resident communication and records.
If you have just been handed the water portfolio on your RWA committee, this is the whole job in one page.
1. Build the tank inventory
Before anything else, walk the property and write down every water asset: underground reservoirs, block overhead tanks, standalone tanks, capacity of each, and where the access hatch is. Most committees discover at least one tank nobody had on their list. You cannot contract for what you have not counted.
2. Set the frequency by resolution
Twice a year is the minimum for Delhi societies; three times if you take tanker deliveries in summer. Put it in a resolution so it survives the next committee change — this is the single most effective thing you can do, because the failure mode is never a bad decision, it is a forgotten one.
3. Compare vendors on scope, not price
- Mechanised or manual? Does anyone enter the tank?
- Which disinfectant, at what dose, and is it food-grade?
- Are before-and-after photos provided per tank?
- Is a written service report issued naming each tank?
- GST-compliant invoice against a registered GSTIN?
- Is labour insured, and who carries confined-space liability?
4. Sequence the round correctly
UGR first, overhead tanks after. Every time. Cleaning the overhead tanks first means refilling them from an uncleaned reservoir, and the society has paid to relocate its silt.
5. Communicate
Notice 48 hours ahead with the block-by-block window. Stagger so no block is dry more than a couple of hours. Post the before-and-after photos on the society group afterwards — it is the cheapest goodwill a committee will ever buy, and it ends the "did they actually do it" thread before it starts.
6. File the records
Service report, photographs, invoice, and the resolution. Keep them together. If a resident ever raises a water-quality complaint, that file is the committee’s answer.
Budgeting
| Society size | Per round | Annual (2 rounds) |
|---|---|---|
| 2 blocks + UGR | ₹9,000 – ₹14,000 | ₹18,000 – ₹28,000 |
| 4 blocks + UGR | ₹18,000 – ₹30,000 | ₹36,000 – ₹60,000 |
| 8 blocks + 2 UGRs | ₹40,000 – ₹65,000 | ₹80,000 – ₹1,30,000 |
An AMC typically runs 10–15% below the per-visit total and removes the annual re-tendering exercise.
