How to Launch a Packaged Drinking Water Brand in Tamil Nadu

Packaged drinking water looks like a simple business from the outside: water, bottles, a label and a truck. In practice it’s one of the most regulated and competitive FMCG categories in India. Every town in Tamil Nadu already has several brands, margins per case are thin, and food safety rules for water are stricter than for most foods.

I’m building Sparow, a packaged drinking water brand in South Tamil Nadu, so this guide is written from inside the category. It covers the licences and approvals, the plant and quality setup, costs to plan for, and how to actually sell. Rules change, so treat this as a map and confirm every requirement with the authorities and a qualified consultant before you invest.

Understand the category first

Before licences, be honest about the market:

• It’s crowded. National brands, strong regional players and many local brands compete in most districts.
• Margins per unit are thin. Profit comes from volume, route efficiency and low damage.
• Water is heavy. Transport cost limits how far you can sell profitably. See how to calculate distribution cost per case.
• Trust is everything. One quality complaint can damage a brand in a town.
• Several segments: small bottles, 1 litre and 2 litre bottles, 20 litre jars, cups and pouches, each with different buyers and economics.

Choosing your segment early shapes your plant, pack and customers. 20 litre jars serve homes and offices on a route basis; bottles go to shops, hotels, events and travel. Many brands start with one and add the other.

Licences and approvals

This is the part to get exactly right. The list below covers the approvals typically involved for a packaged drinking water plant in Tamil Nadu. Requirements can depend on your capacity, location and water source, and they change over time, so confirm each one with the relevant authority.

1. FSSAI licence

Manufacturing packaged drinking water needs an FSSAI licence, applied for through the FoSCoS portal. Whether you need a state or central licence depends on factors like your production capacity. Your product has to meet the FSSAI standards for packaged drinking water, which also refer to the Indian standard (IS 14543).

In late 2024 FSSAI classed packaged drinking water and mineral water as high-risk food categories. In practice, this means risk-based inspections (including inspection before a licence is granted or renewed) and, for centrally licensed manufacturers, mandatory third-party audits. Plan for regular, documented testing and clean records from day one.

2. BIS certification: what changed

For many years, packaged drinking water needed mandatory BIS certification (the ISI mark) before it could be sold. In October 2024, the government removed that mandatory requirement, and FSSAI became the main regulator with stronger inspections. Some manufacturers still choose voluntary BIS certification for buyer confidence. Check the current position on the BIS website and with FSSAI before you plan your certification and labelling, and don’t print an ISI mark unless you hold a valid licence for it.

3. Pollution control consent

A water treatment and bottling plant typically needs consent from the Tamil Nadu Pollution Control Board: consent to establish before building and consent to operate before production. The plant will produce reject water from treatment, so plan how you handle it.

4. Permission to draw groundwater

If your source is a borewell, drawing groundwater for commercial packaging usually needs permission. Depending on location, this can involve Tamil Nadu’s groundwater authorities and the Central Ground Water Authority, and some areas restrict new extraction. Check this before you buy or lease land, because the water source decides whether the plant is possible at all.

5. Legal Metrology registration

As a packer of pre-packaged commodities, you register under the Legal Metrology (Packaged Commodities) Rules, and your labels must carry the required declarations: manufacturer or packer details, net quantity, MRP, date of manufacture, consumer care details and so on.

6. Business registrations

• Company or firm registration.
• GST registration on the GST portal. GST rates for water have changed over time, so confirm the current rate for your products in the CBIC rate schedules or with your accountant.
• Udyam registration for MSME benefits.
• Local body trade licence and building approvals.
• Factory licence, fire safety and electrical approvals as applicable.

7. Trademark

Water brands often have similar-sounding names. Search and apply on the IP India portal before you print anything.

The plant and quality setup

A typical plant includes raw water storage, treatment (filtration, often reverse osmosis, and disinfection such as ozonation or UV), treated water storage, filling and capping (automatic or semi-automatic), labelling, and for jars, washing equipment. The exact process depends on your raw water quality and your product.

Quality is where water brands live or die:

• A testing setup and trained staff for routine checks.
• Regular testing at an accredited external laboratory.
• Batch records, cleaning schedules and equipment maintenance logs.
• Hygiene in filling rooms and among staff.
• A recall plan, written down before you need it.

Costs to plan for

Costs vary hugely with capacity, automation, land and segment, so I won’t quote a single figure. Make a budget for each of these heads and get several quotes:

Cost head	What to include
Land and building	Owned or leased, plant layout, hygiene-grade finishes
Water source	Borewell or supply, permissions, storage
Plant and machinery	Treatment, filling, capping, labelling, jar washing
Testing	Testing equipment, consumables, external lab tests
Licences and consultants	Application fees, documentation, audits
Packaging	Preforms or bottles, caps, labels, shrink wrap, jars
Power and backup	Electricity and generator
Vehicles and distribution	Delivery vehicles or distributor costs
Working capital	Stock, packaging inventory, market credit for several months

Working capital is the line most founders underestimate. Plan for months of operations before routes cover their costs.

Building the brand in a crowded category

Water looks the same in every bottle, so your brand has to win on things buyers notice:

• Reliability: always in stock, delivered on time. This is Sparow’s core positioning.
• Visible quality: clean, well-sealed packs, clear labels, test reports on request.
• Service: fast replacement and responsive support for shops and bulk buyers.
• Pack design: recognisable on a crowded cooler shelf.

I’ve written more about this in how to make a new FMCG brand stand out.

Selling packaged drinking water

Start close to your plant, where freight is lowest. Typical customers:

• Retail: provision stores, bakeries, tea shops and petrol bunks with coolers.
• Bulk buyers: hotels, restaurants, offices, hospitals, schools, factories, events and caterers.
• Homes and offices: 20 litre jar routes on fixed days.
• Distributors: for areas beyond your own routes.

Bulk buyers often give steadier volume than retail. Sparow serves this segment through its bulk packaged drinking water supply in South Tamil Nadu. For how to win these accounts, see how to get hotels, restaurants and offices as bulk buyers.

Common mistakes

• Buying land before checking groundwater permission and pollution consent.
• Choosing a brand name without a trademark search.
• Printing labels or marks without confirming current requirements.
• Skipping regular external lab tests to save money.
• Selling far from the plant before covering nearby routes.
• Competing only on price in a category where everyone can discount.
• Underestimating working capital and market credit.

Frequently asked questions

What licences are needed to start a packaged drinking water business in Tamil Nadu?

Typically an FSSAI manufacturing licence, consent from the Tamil Nadu Pollution Control Board, permission to draw groundwater where applicable, Legal Metrology packer registration, GST registration, local body, factory and fire approvals, and a trademark. Confirm each with the authority, as requirements depend on capacity, location and source.

Is BIS certification mandatory for packaged drinking water?

Not since October 2024, when the mandatory BIS certification requirement was removed and FSSAI took over as the main regulator with risk-based inspections. Some brands still choose voluntary BIS certification. Check the current rules before planning.

Is packaged drinking water a high-risk food under FSSAI?

Yes. FSSAI classed packaged drinking water and mineral water as high-risk food categories in late 2024, which brings risk-based inspections and, for centrally licensed manufacturers, third-party audits.

How much does it cost to start a water bottling plant?

It varies widely with capacity, automation, land, segment and water source. Budget separately for land and building, water source, machinery, testing, licences, packaging, power, distribution and several months of working capital, and get multiple quotes.

Is packaged drinking water a profitable business?

It can be, but margins per unit are thin, so profit depends on volume, efficient routes close to the plant, low damage and a strong base of reliable bulk and retail customers.
