GHMC parks and medians switch to STP-treated water: what changed in November 2026
Last checked: 6 Nov 2026, ~10:25 AM IST
Next update: if GHMC or HMWSSB publish a formal tariff circular or expand the green-tanker STP list.
In short
Greater Hyderabad Municipal Corporation (GHMC) has stopped using fresh drinking (potable) water to maintain urban greenery. Parks, colony lung spaces and central medians are switching to treated water from sewage treatment plants (STPs), delivered by municipal tankers reprogrammed as “Green Tankers”, in coordination with HMWSSB (Telangana Today, 5 Nov 2026, 3:26 PM).
This page explains the city policy. For how residents, industries or builders book and pay for green tankers, use Green water tanker booking & charges — we do not repeat that booking walkthrough here.
What GHMC changed (as of 5 Nov 2026)
| Item | Reported detail | Source |
|---|---|---|
| Policy | Halt potable water for parks / medians / urban greenery; use STP-treated water instead | Telangana Today, 5 Nov 2026, 3:26 PM |
| Fleet | GHMC Urban Biodiversity (UBD) wing reprogrammed 50–60 municipal tankers as Green Tankers drawing from decentralised STPs | Telangana Today, 5 Nov 2026, 3:26 PM |
| Uses named | Parks, urban forestry, central medians on main roads and under flyovers | Telangana Today, 5 Nov 2026, 3:26 PM |
| Tanker sizes | 5,000 and 12,000 litres | Telangana Today, 5 Nov 2026, 3:26 PM |
| Parks named | Krishna Kanth Park; Jalagam Vengal Rao Park (sustained with tankers after deficit rainfall dried many GHMC borewells and park ponds) | Telangana Today, 5 Nov 2026, 3:26 PM |
| KBR Park | Using 4–5 treated-water tankers; Park Manager L. Srinivas said numbers can rise if demand rises | Telangana Today, 5 Nov 2026, 3:26 PM |
| Why now | Deficit rainfall; pressure on groundwater and reservoirs ahead of a possible summer water crisis (as framed by the report) | Telangana Today, 5 Nov 2026, 3:26 PM |
El Niño contingency talks — official estimates / forecasts (not certainties)
At a NAREDCO Telangana + CREDAI Hyderabad workshop on El Niño contingency (reported 5 Nov evening), civic and water-board officials outlined summer planning (Times of India, 5 Nov 2026, 23:47 IST):
| Statement | Who | Label |
|---|---|---|
| City could face a shortfall of around 100 MGD next summer as Manjira–Singur approach depletion and groundwater recharge stays poor | HMWSSB MD K Ashok Reddy | Official estimate / forecast — not a guaranteed outcome |
| Working on about +40 MGD via a pending scheme and another 50–60 MGD from alternatives; a 40–50 MGD deficit could still remain | Same | Official planning scenario |
| Filling stations installed at 30 STPs; digital Green Tanker platform for industries and builders to procure treated wastewater | HMWSSB (as reported) | Operational claim as reported |
| Treated wastewater supply “priced at ₹25” | TOI reporting of board supply | As reported by TOI — the unit (per kilolitre / per tanker / other) is not clear in the article; we do not invent a per-litre price |
| Continue treated water for landscaping, construction and cleaning even after the current crisis; rainwater harvesting in every ward on a participatory model | Cyberabad commissioner G Srijana | Policy intent as quoted |
| Illegal commercial borewells add pressure; enforcement continues | HYDRAA commissioner A V Ranganath | Enforcement stance as reported |
| Priority for groundwater should be domestic; commercial users should look at alternatives | HMWSSB MD K Ashok Reddy | Policy priority as quoted |
None of the MGD figures above are weather predictions we independently verify — they are officials’ summer-planning estimates as of 5 Nov 2026.
What this means for residents
- Parks staying green with STP water is meant to free potable supply for homes — it does not by itself refill your hostel or flat tank.
- Green / STP-treated water is for non-drinking uses. Do not treat park-irrigation water or green-tanker fills as drinking water unless an official source says a specific supply is potable.
- To book treated water for construction, industry or non-potable site use: follow Green water tanker booking & charges (digital platform / filling stations context also appears in Times of India, 5 Nov 2026).
- Hostel / PG stress after the tanker strike: Hyderabad PG and hostel water shortage, November 2026.
- Strike called off 4 Nov evening: Private water tanker strike in Cyberabad.
- Safety if you use any tanker for domestic needs: Tanker water safety.
- Broader climate / supply context: El Niño learn hub and Hyderabad groundwater drop 2026.
