Water and Sanitation as a Constitutional “Minimum Core” Right

Meaning of “Constitutional Minimum Core”

The expression “minimum core” refers to the basic essential level of a socio-economic right that the State must guarantee immediately, irrespective of financial or administrative limitations. In the context of water and sanitation, it means every person must have access to:

• Safe drinking water
• Basic sanitation and sewage facilities
• Hygienic living conditions
• Protection from water contamination
• Equal and non-discriminatory access to water resources

In constitutional jurisprudence, courts across the world — especially in India, South Africa, and through international human rights law — have treated water and sanitation as part of the right to life, dignity, health, and environment.

In India, even though the Constitution does not expressly mention a “right to water,” courts have interpreted it from:

• Article 21 – Right to Life and Personal Liberty
• Article 14 – Equality
• Article 15 – Non-discrimination
• Article 39(b) – Distribution of material resources for common good
• Article 47 – Duty of State to improve public health
• Article 48A – Protection of environment
• Article 51A(g) – Fundamental duty to protect nature

The judiciary has progressively developed a constitutional framework where access to clean water and sanitation is considered indispensable to human dignity.

Important Constitutional Principles

1. Right to Life Includes Right to Water

The courts have repeatedly held that life under Article 21 means more than animal existence. It includes:

• Health
• Clean environment
• Pollution-free water
• Dignified living conditions

Without water and sanitation, these rights become meaningless.

2. State Has Positive Obligations

The State cannot merely avoid interference; it must actively:

• Provide water infrastructure
• Prevent contamination
• Regulate industries
• Ensure equitable distribution
• Protect vulnerable communities

3. Water Is a Public Trust

Natural resources like rivers, lakes, and groundwater belong to the people. The government acts as a trustee and cannot allow private exploitation that harms public access.

Detailed Case Laws

1. Subhash Kumar v. State of Bihar

Facts

Subhash Kumar filed a petition alleging that industrial slurry and waste from coal washeries were being discharged into the Bokaro River in Bihar, making the water unsafe for drinking and domestic use.

He argued that pollution destroyed the ability of people to enjoy clean water and violated Article 21.

Issues

• Whether the right to pollution-free water is part of Article 21.

Judgment

The right to life includes the right to enjoy pollution-free water and air for full enjoyment of life.

The Court recognized environmental protection as an integral constitutional obligation.

Although the petition itself was later dismissed on factual grounds, the legal principle became highly influential.

Constitutional Importance

This case was among the earliest explicit recognitions that:

• Clean water is constitutionally protected.
• Environmental degradation directly violates fundamental rights.
• Access to safe water is part of human dignity.

Contribution to Minimum Core Doctrine
