Residential segment (RO/UV purifiers, Rs 5,000–Rs 25,000 unit price):
- The installer is usually a neighbourhood plumber or a brand-authorized local dealer who buys inventory at a discount and marks it up 20–35% on sale
- Post-installation, AMC contracts (typically Rs 800–Rs 2,500 per year) are sold at point of sale or renewed by phone/WhatsApp
- AMC tracking is a physical notebook or an Excel sheet at most dealer shops; 30–40% of renewals are missed because there is no systematic reminder system
- Service call dispatch: customer texts or calls the dealer, dealer WhatsApp messages a technician, technician confirms slot verbally — no job management software anywhere in this chain
- Spare parts: purchased from regional distributors (one per city for major brands), collected by technician on credit, settled monthly
- Project cycle: site survey → water analysis → equipment sizing → budgetary quote → technical spec → purchase order → installation → commissioning → AMC
- Survey and water analysis are done by a site engineer using a portable multi-parameter meter (pH, TDS, turbidity, chloride) and sent by email or WhatsApp to the technical head
- Quotes are built in Excel by senior engineers who guard their calculation methodology; junior staff just execute
- Procurement for government and large corporate clients goes through tender/RFQ; private players use direct negotiation
- AMC for commercial plants is typically Rs 1–5 lakh per year, managed by the installing vendor who sends a technician monthly or quarterly
- Governed by CPHEEO (Central Public Health and Environmental Engineering Organisation) guidelines and state-level PHE (Public Health Engineering) departments
- Tenders are issued by state water boards; technical specifications are written by consulting engineers
- Execution is by large EPC players (Ion Exchange, VA Tech Wabag, Thermax) who subcontract installation to local civil contractors
- Compliance reporting to pollution control boards (SPCB/CPCB) is done manually on paper forms, filed quarterly
- Missed AMC renewals: 30–40% of residential AMC base lapses, taking recurring revenue with it
- Technician underutilisation: field technicians serving a city make 3–5 calls per day; with better scheduling, 6–8 is achievable
- Water analysis reports: a junior engineer spends 2–3 hours typing up a site survey report that a well-structured prompt can draft in under a minute
- Parts inventory: dealers hold 2–3 months of slow-moving stock because reorder signals are manual
- Compliance filings: SPCBs require periodic reports; most commercial plants either hire a consultant (Rs 15,000–30,000 per filing cycle) or delay filing
