Packaged water is the rare food business where the licence IS the barrier: selling packaged drinking water without the BIS ISI mark is illegal, full stop — and that single requirement filters out the informal competition that plagues every other food category. On the other side of the barrier sits a daily-consumption product with route-based B2B economics (the 20-litre jar trade) and steady margins. Here is the full plant build, compliance stack and the honest market math.
The compliance stack — BIS first
- BIS certification (IS 14543 for packaged drinking water; IS 13428 for natural mineral water) is mandatory before sale: factory-level licence with in-house lab requirements, initial testing, and surveillance — the process runs 3–6 months and defines your plant design
- FSSAI manufacturing licence (state/central by scale) rides alongside; water is a high-attention category
- Groundwater NOC (CGWA/state authority) for borewell extraction — increasingly enforced and volume-metered; apply before drilling
- Pollution board CTE/CTO (reject-water disposal is the environmental question — RO reject is 25–40% of intake; plan reuse/disposal)
- The rest: Legal Metrology (fill volumes verified — enforcement samples water constantly), trade licence, GST (water in 20L jars vs bottles carries different rate treatments — take current advice)
Plant design and machinery
The processing chain: raw water storage → sand/carbon filtration → softening → RO (the heart — sized 1,000–10,000 LPH for small-to-mid plants) → UV + ozonation → storage → filling lines. Costs: a 2,000 LPH RO-plus-treatment train runs ₹8–15 lakh; jar-filling semi-automatic lines ₹3–6 lakh (with jar-washing machines — hygiene inspections focus here); bottle lines (rinse-fill-cap) ₹8–20 lakh for entry automation plus blow-moulding if you make your own PET bottles (₹10–18 lakh — usually a phase-two decision versus buying preformed); the mandatory in-house lab (microbiology + chemical basics per BIS) ₹3–6 lakh. Premises: 2,000–4,000 sqft with BIS-compliant layouts. All-in: jar-focused plants launch at ₹25–45 lakh; jar+bottle plants ₹45 lakh–1 crore. PMEGP/state MSME subsidies apply; water plants are standard DIC fare.
The 20L jar trade is a ROUTE business: B2B/home delivery, ₹25–50 per jar to the customer, your economics living on route density, jar-return discipline (each jar is ₹120–180 of your capital circulating) and monthly-billing relationships. Bottles are a BRAND/distribution business: retail margins fought against giants, cold-chain-free but placement-driven. New plants should win jars first — predictable cash, local moats — and treat bottles as expansion.
The jar-route playbook
- Unit math: production cost ₹8–14 per 20L jar (power, consumables, labour, jar amortisation); sold at ₹20–35 to route customers or via distributors — 40–60% gross margins
- Route density decides profit: 150–250 jars/day per delivery vehicle is the viability line; offices, shops, clinics and PGs anchor routes
- Jar control: deposits (₹100–150) against jars, tagging, and monthly reconciliation — jar loss is the silent margin eater
- Institutional contracts: hospitals, factories, banquet halls and events (bulk + dispensers) — 5–10 anchors underwrite a plant
- Seasonality: summer doubles demand; plan capacity and casual staffing for the April–June peak that funds the year
Quality: the existential discipline
Water fails invisibly — and BIS surveillance, FSSAI sampling and one contamination incident are each existential. The plant that survives: daily in-house micro/chemical logs (the BIS lab isn't decoration), ozonation residual discipline, jar-washing chemistry actually maintained, borewell water re-tested seasonally (source profiles drift), and batch coding that enables recall. Public confidence in your local brand is the entire moat against the national labels' pull — guard it with paranoia.
How Aidwish helps
Aidwish executes water-plant projects end to end — BIS licensing (the design-stage requirement mapping), groundwater and pollution NOCs, machinery vendor negotiation, subsidy structuring and the route-business launch plan — so the plant clears every mark before the first jar ships.
