Controlling Water Pollution under the Water Act, 1974

Water is the foundation of food production. From washing raw ingredients to processing and packaging, water touches nearly every stage of food manufacturing. If that water is contaminated, everything downstream-including the food on your plate-is at risk. Recognizing this critical connection, India enacted the Water (Prevention and Control of Pollution) Act in 1974, establishing the country’s first comprehensive framework to protect water resources from industrial and domestic pollution.

Why this law matters for food safety 🔗

The Water Act was enacted to prevent and control water pollution and to maintain or restore the wholesomeness of water across the country. While this might seem like a purely environmental law, its implications for the food industry are profound. Food processing facilities rely heavily on clean water for operations ranging from ingredient preparation to equipment sanitation. When water sources become polluted due to industrial discharge or sewage, the contamination can find its way into food products, posing serious public health risks.

The Act defines pollution as contamination or alteration of water’s physical, chemical, or biological properties that may render it harmful to public health, domestic or industrial uses, or harmful to aquatic life. For food businesses, this definition is particularly relevant because water that fails to meet quality standards can introduce pathogens, heavy metals, or chemical contaminants into food products.

The regulatory bodies: Central and State Pollution Control Boards 🔗

One of the most significant contributions of the Water Act was the establishment of specialized regulatory bodies. The Central Pollution Control Board (CPCB) operates at the national level under the Ministry of Environment, Forest and Climate Change, while each state has its own State Pollution Control Board (SPCB). Together, these bodies form the backbone of India’s water pollution control infrastructure.

Functions of the Central Pollution Control Board 🔗

The CPCB serves as the apex pollution monitoring institution in India. Its responsibilities include advising the Central Government on water pollution matters, coordinating activities between State Boards, providing technical assistance, and conducting research on pollution prevention methods. The Board also lays down standards for water quality in streams and wells across different states, ensuring consistency in pollution control measures nationwide.

Additionally, the CPCB compiles and publishes technical data relating to water pollution, prepares manuals for treatment and disposal of sewage and trade effluents, and organizes mass media programmes to raise public awareness about water conservation and pollution prevention.

Functions of State Pollution Control Boards 🔗

State Boards handle the ground-level implementation of pollution control measures. Their functions include planning comprehensive programmes for pollution prevention in local streams and wells, inspecting sewage and trade effluent treatment facilities, and advising state governments on the location of industries that might pollute water sources.

Critically for food businesses, State Boards lay down effluent standards that industries must comply with when discharging wastewater. They also evolve methods for utilizing treated sewage in agriculture and develop efficient disposal techniques tailored to local conditions.

The consent mechanism: How industries must comply 🔗

The Water Act introduces a robust consent mechanism that directly impacts food processing facilities and other industries. Under Section 25 of the Act, no person can establish any industry, operation, or process that is likely to discharge sewage or trade effluent without obtaining prior consent from the State Pollution Control Board.

What requires consent 🔗

The consent requirement applies to establishing new industries or treatment systems, bringing new or altered outlets into use for discharge, and beginning any new discharge of sewage or effluents. Food processing units, dairy plants, beverage manufacturers, and meat processing facilities all fall under this provision if they discharge wastewater into streams, wells, sewers, or onto land.

When granting consent, the State Board may impose conditions regarding the point of discharge, the nature and composition of effluents, temperature limits, volume, and rate of discharge. These conditions become binding on the facility, and the Board maintains a register of all conditions imposed, which is open to public inspection.

Existing discharges under Section 26 🔗

Facilities that were already discharging effluents before the Act came into force must also apply for consent under Section 26. This ensures that all industrial operations, whether new or existing, are brought under the regulatory framework.

Powers of inspection and sampling 🔗

The Act grants extensive powers to pollution control authorities to monitor compliance. Under Section 21, State Boards can take samples of water from streams or wells, as well as samples of sewage or trade effluents being discharged. The sampling procedure is carefully prescribed to ensure the evidence is admissible in legal proceedings.

When collecting a sample, officials must serve notice to the occupier of the facility, divide the sample into two parts in the presence of the occupier’s representative, seal both containers with signatures of both parties, and send one container to the Board’s laboratory and the other to a designated government laboratory if requested. This dual-sample procedure protects both the regulatory authority and the facility operator by ensuring transparency in testing.

Officers empowered by the Board can also enter any premises to inspect plants, examine records, and verify compliance with the Act’s provisions. For facilities handling food products, these inspections can reveal whether water treatment systems are functioning properly and whether effluent standards are being maintained.

Prohibition on polluting water sources 🔗

Section 24 of the Act contains a direct prohibition against causing water pollution. It states that no person shall knowingly cause or permit any poisonous, noxious, or polluting matter to enter any stream, well, sewer, or land. This prohibition is crucial for food safety because contaminated water sources can affect not only the polluting facility but also downstream users, including other food producers, farms using irrigation water, and communities depending on the water for drinking.

The Act also prohibits causing any matter to enter streams that would impede water flow in ways that aggravate pollution. This addresses the practical reality that pollution problems often compound when waste materials accumulate and reduce a water body’s natural capacity to dilute and process contaminants.

Emergency powers and directions 🔗

When pollution poses an immediate threat, the Act provides for emergency response. Under Section 32, if poisonous or polluting matter is present in a stream or well and the Board believes immediate action is necessary, it can carry out operations to remove the polluting matter, remedy or mitigate pollution, and issue orders restraining further discharge.

Section 33A grants Boards broad power to issue directions to any person, officer, or authority, including the power to direct closure of industries, prohibition or regulation of operations, and stoppage of electricity or water supply. These powers ensure that regulatory authorities can act decisively when pollution threatens public health or the environment.

Penalties for non-compliance 🔗

The Water Act imposes significant penalties for violations, demonstrating the seriousness with which India treats water pollution. Contravening Section 25 or 26 (operating without consent) carries imprisonment of not less than one year and six months, extendable to six years, along with fines.

Violating Section 24 (polluting water sources) attracts similar penalties. For repeat offenders, the punishment increases to imprisonment of not less than two years, extendable to seven years. Providing false information, obstructing officials, or damaging Board property can result in imprisonment up to three months or fines up to ten thousand rupees.

These penalties apply not just to individual operators but also to companies. Where an offence is committed by a company, every person in charge of and responsible for the company’s business is deemed guilty unless they prove the offence occurred without their knowledge or despite exercising due diligence.

Connection to food industry water standards 🔗

While the Water Act focuses on preventing pollution of natural water sources, food businesses must also comply with water quality standards set by the Food Safety and Standards Authority of India (FSSAI). FSSAI mandates that all food businesses use potable water meeting Bureau of Indian Standards (BIS) specifications.

The Indian Standard IS 4251 specifically covers water for food processing, requiring compliance with bacteriological, physical, chemical, and radioactivity tolerance limits. Parameters tested include pH, turbidity, total dissolved solids, hardness, various metallic ions, and toxic substances including pesticide residues.

By controlling pollution at the source through the Water Act and ensuring potable water standards through FSSAI regulations, India has created a comprehensive framework protecting water quality throughout the food production chain.

Recent developments and amendments 🔗

The Water Act was amended in 1978 and 1988 to clarify certain provisions and vest more powers in Pollution Control Boards. The 1988 amendments particularly strengthened the consent mechanism and enhanced penalties for violations.

The Water (Prevention and Control of Pollution) Cess Act of 1977 was also enacted to levy and collect a cess on water consumed by certain industries. This cess helps fund the operations of Central and State Pollution Control Boards, ensuring they have resources to carry out their functions effectively.

What do you think? How can food businesses better integrate water quality management into their overall food safety systems? Given that water pollution affects not just individual facilities but entire communities and ecosystems, what role should food industry associations play in advocating for stronger enforcement of the Water Act?
