FSSAI and Water: The Regulatory Intersection
Water is simultaneously a food ingredient, a food processing medium, and a packaged food product. This means FSSAI’s jurisdiction over water safety covers a broader scope than most food manufacturers realise.
If your business:
- Manufactures packaged drinking water or pouch water
- Produces natural mineral water or spring water
- Uses water as a direct ingredient in beverages, dairy, or ready-to-eat food
- Operates a food processing facility where water contact surfaces are cleaned with water
— then FSSAI’s water quality requirements apply to you, and testing is mandatory.
This guide focuses primarily on packaged drinking water and natural mineral water — the categories with the most prescriptive FSSAI testing requirements.
The Dual Standard Regime: FSSAI + BIS
Packaged water in India operates under two parallel regulatory regimes that manufacturers must comply with simultaneously:
FSSAI (Food Safety and Standards Authority of India): Regulates packaged water as a food product under the Food Safety and Standards Act, 2006. Requires FSSAI registration/license, sets product standards, mandates labeling, and enforces through surveillance testing.
BIS (Bureau of Indian Standards): Certifies packaged water under the mandatory BIS certification scheme. Manufacturers must hold BIS license (ISI mark) before marketing packaged drinking water (IS 14543) or natural mineral water (IS 13428). Operating without BIS certification while selling packaged water is a criminal offence under the BIS Act.
Both FSSAI and BIS reference IS 14543 and IS 13428 as the product standards. The practical result is that a packaged water manufacturer must simultaneously:
- Hold a valid FSSAI license (Central license for pan-India distribution; State license for single-state)
- Hold a BIS license for the relevant standard
- Conduct periodic third-party testing at a NABL-accredited laboratory
IS 14543: Packaged Drinking Water (Other Than Natural Mineral Water)
IS 14543:2016 is the standard for “packaged drinking water” — what most consumers know as bottled water or packaged water. It covers water that has been processed (typically through reverse osmosis, UV treatment, ozonation, or a combination) to meet quality specifications.
Key Quality Parameters Under IS 14543
Physical/Aesthetic Parameters
| Parameter | Requirement |
|---|---|
| Colour | Maximum 5 Hazen units |
| Turbidity | Maximum 1 NTU |
| Odour | No objectionable odour |
| pH | 6.5–8.5 |
| Total Dissolved Solids | 500 mg/L maximum |
The TDS maximum of 500 mg/L is more stringent than IS 10500’s acceptable limit of 500 mg/L (same value, but IS 14543 has no permissible relaxation). The TDS minimum is 150 mg/L — water with very low TDS is considered flat tasting and may leach minerals from body tissues on regular consumption, so demineralization must be controlled.
Chemical Parameters — Selected Key Limits
| Parameter | IS 14543 Limit |
|---|---|
| Arsenic | 0.01 mg/L |
| Lead | 0.01 mg/L |
| Cadmium | 0.003 mg/L |
| Mercury | 0.001 mg/L |
| Fluoride | 1.0 mg/L |
| Nitrate (as NO₃) | 45 mg/L |
| Nitrite (as NO₂) | 0.02 mg/L |
| Chromium (hexavalent) | 0.05 mg/L |
| Copper | 1.0 mg/L |
| Iron | 0.3 mg/L |
| Manganese | 0.1 mg/L |
| Chloride | 250 mg/L |
| Sulphate | 200 mg/L |
| Total Hardness (as CaCO₃) | 200 mg/L |
| Alkalinity (as HCO₃) | 200 mg/L |
| Boron | 2.4 mg/L |
Disinfection Residuals
For water treated with ozone:
- Ozone residual: Maximum 0.2 mg/L in the final product
For chlorinated water:
- Free residual chlorine: As per treatment efficacy without leaving objectionable taste/odour
Microbiological Requirements
| Parameter | Requirement |
|---|---|
| Total Plate Count (TPC) at 22°C | Maximum 100 CFU/mL |
| Total Plate Count (TPC) at 37°C | Maximum 20 CFU/mL |
| Total Coliforms | Absent in 100 mL |
| Faecal Coliforms (E. coli) | Absent in 100 mL |
| Faecal Streptococci | Absent in 100 mL |
| Pseudomonas aeruginosa | Absent in 250 mL |
| Staphylococcus aureus | Absent in 250 mL |
| Cryptosporidium oocysts | Absent in 10 L |
| Giardia lamblia cysts | Absent in 10 L |
The requirements for Pseudomonas aeruginosa (absent in 250 mL) and Cryptosporidium/Giardia (absent in 10 L) are more stringent than typical drinking water standards and reflect the higher quality expectations for commercially processed packaged water.
Container Requirements
IS 14543 specifies requirements for packaging materials. PET (polyethylene terephthalate) bottles must be food-grade with limits on acetaldehyde migration (≤10 mg/kg), antimony migration (≤5 μg/L), and other plastic additive migration. Returnable multi-trip containers (19-litre jar dispensers) face additional sanitation and refill protocols.
IS 13428: Natural Mineral Water
IS 13428 governs natural mineral water — water obtained from underground sources through springs, tunnels, or boreholes, with characteristics arising from the mineral composition of the source rock. Unlike packaged drinking water, natural mineral water cannot be treated with disinfectants (with limited exceptions); its safety derives from source protection and natural microbial stability.
Distinctions from Packaged Drinking Water
| Aspect | Packaged Drinking Water (IS 14543) | Natural Mineral Water (IS 13428) |
|---|---|---|
| Source | Any potable source | Natural underground spring/borehole |
| Treatment | Filtration, RO, UV, ozonation permitted | No disinfection treatment; limited filtration |
| TDS | 150–500 mg/L | No upper limit specified (mineral character preserved) |
| Labeling | ”Packaged Drinking Water" | "Natural Mineral Water” with source name |
| Price point | Mass market | Premium |
| Compliance complexity | Moderate | High (source approval + ongoing testing) |
Source approval is a significant regulatory requirement unique to natural mineral water. FSSAI requires hydrogeological survey reports, source characterization data, and seasonal consistency data before approving a source for natural mineral water production.
Key Microbiological Requirements for Natural Mineral Water
Given that chemical disinfection is not permitted, microbiological requirements place more emphasis on source protection and characterization:
- Escherichia coli and total coliforms: Absent in 250 mL
- Pseudomonas aeruginosa: Absent in 250 mL
- Total plate count at 22°C: <100 CFU/mL within 12 hours of source collection
- Parasites (Cryptosporidium, Giardia): Absent in specified sample volumes
- Absence of any pathogenic organisms
Pesticide Residue Testing for Water
Both IS 14543 and IS 13428 include limits for pesticide residues that have become increasingly relevant given India’s agricultural chemical use patterns. FSSAI’s water standards mirror IS 10500:2012 pesticide limits:
- Total pesticides: Maximum 0.001 mg/L (1 μg/L)
- Individual pesticide limits: Vary by compound; typically 0.0001–0.0005 mg/L
- Organochlorine pesticides (alpha-BHC, beta-BHC, gamma-BHC, DDT, heptachlor): Maximum 0.0001 mg/L each
- Malathion: 0.0001 mg/L
- Endosulfan: 0.0001 mg/L
Pesticide residue testing for water requires GC-MS/MS methods with pre-concentration steps to achieve the required detection limits in the parts-per-trillion range.
FSSAI License Types for Packaged Water
Registration: For very small packaged water businesses (turnover below ₹12 lakh/year). Limited regulatory oversight; not practically applicable to commercial-scale packaged water operations.
State FSSAI License: For manufacturers distributing within a single state. Regulated by State Food Safety Commissioner.
Central FSSAI License: For manufacturers distributing across multiple states, or with turnover above ₹20 crore. Regulated by FSSAI central authority in New Delhi. Required for export and for supply to centrally regulated establishments.
All commercial packaged water manufacturers in practice require Central FSSAI License given multi-state distribution. The license renewal cycle is 1–5 years (manufacturer’s choice) and requires documentation of testing records.
Mandatory Testing for FSSAI Compliance
FSSAI regulations require packaged water manufacturers to maintain testing records demonstrating product compliance. While FSSAI does not prescribe exact testing frequency in all cases, industry practice (aligned with BIS licensing requirements) is:
In-house testing (process control)
- Microbiological: Daily or per production batch
- Physical (pH, TDS, turbidity): Continuous or per batch
Third-party accredited laboratory testing
- Full IS 14543 / IS 13428 panel: Quarterly minimum
- Pesticide residues: Quarterly
- Heavy metals: Quarterly
- Microbiological: Monthly
Records must be maintained for minimum 2 years and must be produced on demand during FSSAI inspection.
