Install, service, and maintain home RO water purifiers on a phone-booked, AMC basis - the lowest-cost entry point into India's fast-growing water purifier industry.

India's water purifier market was valued at about $3.64 billion in 2025 and is projected to grow at an 8.4% CAGR to reach roughly $7.5 billion by 2034 (per IMARC Group), driven by rising awareness of waterborne disease risk - a large and growing installed base of purifiers that all need periodic filter changes and servicing, which is exactly the recurring-revenue opportunity an AMC business captures.
Households and small offices that already own an RO purifier (any brand) and need annual filter changes, servicing, or repair, rather than a totally new installation.
Sell annual maintenance contracts (AMC) covering a fixed number of service visits and filter changes per year, plus one-off installation and repair charges for new or out-of-contract customers.
Faster response time than brand call centres (which often have multi-day waiting lists during peak demand) plus honest, multi-brand service (not pushing unnecessary filter changes) builds trust that keeps AMC customers renewing year after year.
A good low-capital entry if you can build a base of 50-100 AMC customers for recurring income - skip this if you cannot commit to timely, reliable service calls, because AMC businesses live or die on response time and a single missed filter-change visit can lose a customer for good.

The service-and-AMC model is explicitly the lowest-cost entry point among water-purifier business models per IIFL Finance's guide (compared to a dealership model at roughly Rs 3-5 lakh or an own-RO-plant model at Rs 5-15 lakh). A basic service toolkit, a stock of common filters/membranes, and a two-wheeler for visits can realistically start well under Rs 50,000. Mudra loans (Shishu/Kishore/Tarun/Tarun Plus) range from Rs 50,000 to Rs 20 lakh for scaling up.
No independently verified per-technician earnings figure for the RO service/AMC trade in India was found, so treat specific income claims online with caution - income depends on how many AMC contracts you can build and retain over time.

No - an independent AMC/service business can service multiple brands; you do not need brand authorisation, though building relationships with local parts suppliers for genuine filters matters a lot.
Per IIFL Finance's guide, the service-and-AMC model has the lowest entry cost of the three common models (compared to a dealership at roughly Rs 3-5 lakh or an own-RO-plant setup at Rs 5-15 lakh).
India's water purifier market is valued at about $3.64 billion as of 2025 and is projected to reach roughly $7.5 billion by 2034, growing at an 8.4% CAGR, per IMARC Group - meaning a large and expanding installed base that will need ongoing service.
