Why Water Is the Most Overlooked Due Diligence Item
Most PCMC property buyers check RERA registration, OC status, and developer track record. Very few systematically verify water supply. This is a significant oversight — in PCMC’s rapid-development zones, water supply varies dramatically between buildings in the same street, and the difference between a piped PCMC water connection and borewell dependency can mean years of water scarcity, tanker dependency costs, and legal complications.
This guide is the water due diligence framework for PCMC property buyers in 2026.
PCMC’s Water Supply: The System Overview
PCMC sources water primarily from the Pavana Dam (Pimpri-Chinchwad’s dedicated reservoir) and the Andhra Dam as a secondary source. The Pavana reservoir has a total capacity of 327 MCM (million cubic metres), of which PCMC is allocated approximately 250 MLD (million litres per day) water supply.
The core tension: PCMC’s residential population has grown from 15 lakh in 2011 to an estimated 25+ lakh in 2026 — a 66% increase. The Pavana Dam allocation has grown marginally but not proportionally. PCMC supplements piped supply with treated Mula-Mutha River water for industrial use, but residential dependence on Pavana remains.
Result: Peripheral PCMC zones that were developed fastest — particularly the Maan-Marunji, Chikhali, Moshi, and parts of the Hinjewadi-adjacent belt — have gaps in PCMC piped water network coverage. Buildings in these zones supplement with borewell extraction — a practice PCMC has been progressively regulating.
Water Supply Status by Zone
Well-Connected (PCMC Piped Water Reliable)
Pimple Saudagar — Fully covered by PCMC piped network. Established zone with decades of municipal infrastructure. No borewell dependency in established buildings.
Wakad — Core Wakad is well-covered. Some fringe projects near the Hinjewadi-Wakad road boundary have partial coverage — verify for any specific project.
Chinchwad / Pimpri — Fully municipal. PCMC headquarters is in Chinchwad — infrastructure is maximally developed here.
Akurdi / Nigdi — Established PCMC zones with reliable piped supply.
Punawale (large townships) — VTP Realty and Kolte-Patil townships have PCMC piped connections as a condition of their development agreements. Verify for smaller standalone buildings in Punawale fringe.
Adequate but Verify
Ravet — Mostly PCMC piped, but quantity can be 2–3 hours per day during Pavana stress periods (April–June). Confirm the specific building’s storage capacity (minimum 3 days’ storage recommended).
Tathawade — Generally PCMC covered. Newer projects on the Hinjewadi-Tathawade road boundary should be verified.
Chikhali — Mixed. Established Chikhali close to the Aundh-Ravet BRTS road is PCMC-covered. New projects in deeper Chikhali (500m+ from the main road) may rely partially on borewell. Ask for PCMC water connection certificate specifically.
Borewell-Supplementary — Verify Carefully
Maan-Marunji — Under-developed infrastructure. PCMC water line has not fully reached all Maan project sites as of 2026. Developers typically use borewell as primary supply with PCMC as supplementary. Ask the developer specifically: “What is the current PCMC water line status for this project? When does full PCMC connection get activated?” Get the answer in writing.
Moshi — Northern PCMC. PCMC piped coverage is present on main roads, partially reaching residential projects. Confirm per-project.
Bhosari (residential pockets) — Industrial MIDC-zone infrastructure prioritises industrial water supply. Residential buildings in Bhosari may have mixed sources. Verify PCMC residential water connection specifically.
Charholi / Chakan corridor — PMRDA area (not core PCMC). Water supply is less regulated. Borewell dependency is common. PMRDA has different infrastructure timelines.
The Exact Questions to Ask the Developer
Before paying a booking amount:
1. “What is the source of water supply for this building — PCMC piped, borewell, or both?”
If borewell-only: ask what the PCMC water line ETA is and whether it is stated in the RERA filing.
2. “What is the per-flat per-day guaranteed water supply?”
Minimum standard: 135 litres per capita per day (135 LPCD) as per RERA norms. Less than this is inadequate for a family of 4.
3. “What is the building’s water storage capacity?”
Minimum: 3 days’ consumption storage in overhead tanks + underground sump. For a 100-flat building of 4 residents each: 100 × 4 × 135 LPCD = 54,000 litres/day → 3-day storage = 162,000 litres (162 KL). If the overhead tank capacity is listed as under 100 KL for 100 flats, it’s inadequate.
4. “What is the society’s water tanker cost if piped supply fails?”
An honest developer will tell you: ₹800–1,200 per tanker (10,000 litres), with a 100-flat building needing 5–6 tankers per day at full capacity. That’s ₹4,000–7,200/day or ₹1.2–2.2 lakh/month in tanker costs during shortage periods — shared across flats, this is ₹1,200–2,200/month per flat as emergency maintenance cost.
5. “Is there a borewell on the property and is it CGWA-registered?”
The Central Groundwater Authority (CGWA) requires registration for borewells extracting more than 50 cubic metres per day. Unregistered borewells are legally at risk of closure. Verify if the building’s borewell (if used) is CGWA-registered.
The RERA Water Clause
Under MahaRERA, developers are required to specify in the RERA registration:
- The source of water supply
- The anticipated water supply quantity
- The date by which municipal piped connection will be provided (if not already connected)
Download the RERA project document from maharerait.mahaonline.gov.in and search for “water” in the document. If the water supply section is vague or states only “borewell” with no municipal connection commitment, treat it as a red flag.
The Pavana Dam Stress Test
PCMC’s Pavana reservoir has faced stress years when rainfall was below 70% of normal. During such years (2016, 2018 were notable), PCMC implemented:
- 20–30% supply cuts to residential users
- Tanker deployment to peripheral zones
- Scheduled supply every alternate day in some zones
If you’re buying in a peripheral PCMC zone (Moshi, Bhosari, Maan, outer Chikhali), ask about the building’s resilience plan for Pavana stress years: storage capacity, tanker access, and rainwater harvesting (RWH) compliance (mandatory for buildings over 1,000 sq m plinth area in PCMC).
The Bottom Line Checklist
- Ask for PCMC water connection certificate (not just verbal confirmation)
- Verify RERA document for water supply source and quantity
- Check overhead tank + sump capacity against flat count
- Ask about borewell CGWA registration if borewell is the primary source
- For peripheral zones: ask about Pavana stress-year contingency plan
- For under-construction: ask when PCMC connection will be activated and get it in the RERA filing
