Reduce untreated sewage and industrial waste entering rivers
India's rivers are suffering from severe pollution, with 80% of the country's sewage flowing untreated into its waterways. This is having a devastating impact on the environment and public health, as untreated sewage contains harmful pollutants and pathogens. A major cause of this issue is the lack of proper sewage treatment infrastructure; only 160 out of 8,000 towns have both sewerage systems and sewage treatment plants. Furthermore, rapid urban development and weak enforcement of environmental laws have allowed thousands of small factories to discharge untreated sewage and toxic waste into freshwater sources.
To reduce untreated sewage entering Indian rivers, there is a need to invest in wastewater infrastructure upgrades and expansion. This includes constructing more sewerage systems and treatment plants to ensure all towns and cities have access to proper sewage treatment facilities. The Indian government must prioritize this issue and allocate significant resources to address it. Additionally, stricter enforcement of environmental laws and regulations is crucial to hold these factories accountable for their waste disposal practices.
Another strategy to reduce sewage overflow is to implement natural solutions that prevent stormwater from rushing into sewers. This can be achieved through initiatives such as planting trees, restoring wetlands, and creating green roofs, which can effectively expand the capacity of sewer systems and reduce the risk of overflows. These initiatives can also help to filter stormwater, improving the overall water quality that enters the sewer systems.
Public awareness and education about the dangers of sewage pollution are also essential. By informing citizens about the risks associated with untreated sewage, there will be increased pressure and support for reducing sewage pollution. This includes notifying the public when there is a release of untreated sewage into the environment, as well as promoting water conservation and responsible waste disposal practices.
Lastly, legal strategies can be employed to protect Indian rivers. Efforts to obtain legal personhood for rivers have shown promise, as it would allow lawsuits to be brought against those polluting the rivers. This approach has the potential to hold polluters accountable and deter future pollution, offering a longer-term solution to saving India's rivers from untreated sewage and industrial waste.

Improve water treatment infrastructure and capacity
India's rivers are severely polluted due to untreated sewage, agricultural runoff, and industrial waste. This has detrimental effects on both human health and the environment. To improve water treatment infrastructure and capacity, the following measures can be implemented:
Increase Investment in Sewage Treatment Plants
India's major cities produce a vast amount of sewage, with a daily total of 38,354 million litres. However, the current urban sewage treatment capacity only manages 11,786 million litres. This gap between sewage generation and treatment capacity needs to be addressed by investing in new and upgraded sewage treatment plants. These plants should be properly maintained and operated to ensure effective treatment of domestic wastewater.
Promote Public-Private Partnerships
Public-private partnerships can play a crucial role in tackling river pollution. By collaborating with private entities, the government can leverage expertise and resources to improve water treatment infrastructure. This includes developing sustainable and efficient systems for sewage collection, transportation, and treatment.
Strengthen Enforcement of Regulations
The polluting industries must be held accountable for their waste disposal practices. While industries are expected to treat their effluent before releasing it into rivers, many often bypass this treatment process when there is no oversight. Therefore, stricter enforcement of regulations and increased monitoring are necessary to ensure that industries adhere to treatment norms and do not discharge untreated effluent.
Implement Sewage Metering and Pricing
Similar to how utilities like electricity and water are metered and priced, sewage should also be metered. Implementing a sewage metering and pricing system can provide a financial incentive for households and industries to manage their sewage discharge responsibly. This can also generate revenue that can be reinvested in improving water treatment infrastructure.
Encourage Organic Farming Practices
Agricultural runoff, due to the use of chemical fertilizers and pesticides, is a significant contributor to river pollution. By incentivizing farmers to adopt organic farming practices, the use of harmful chemicals can be reduced. This not only improves soil health and yields but also minimizes the pollution entering rivers from agricultural sources.
Explore Innovative Treatment Solutions
Innovative and existing technologies, such as those demonstrated by the Prime Minister of Singapore, can be explored to improve water treatment processes. By adopting advanced treatment methods, India can enhance the quality of treated water and ensure that it meets the required standards for various purposes, including agriculture and industrial use.

Encourage organic farming practices to reduce chemical runoff
India's rivers are severely polluted due to untreated sewage, agricultural runoff, and industrial waste. One way to reduce river pollution is by encouraging organic farming practices to minimize chemical runoff.
Organic farming is an ecological production management system that promotes biodiversity, biological cycles, and soil biological activity. It emphasizes a whole-system approach, creating a sustainable and self-regulating ecosystem. This method works with the natural biodiversity of each farmed area, encouraging the complexity of living organisms, both plant and animal.
In organic farming, the use of synthetic fertilizers, pesticides, and other chemical inputs is eliminated. Instead, farmers utilize organic manures, legumes, crop rotation, residue recycling, biofertilizers, and composting to improve the soil's physical, chemical, and biological properties. This reduces the potential for water runoff and erosion, preventing excess nutrients from entering waterways.
Natural Farming, a type of organic farming, is a chemical-free traditional farming method that integrates crops, trees, and livestock. It encourages the use of local seeds, microbial seed treatment, and microbial inoculants for soil health. The soil is covered with organic mulch, creating humus and promoting beneficial microorganisms. Farm-made bio-cultures, such as 'Jeevamrit' and 'Beejamrit', derived from cow dung and urine, are added to the soil to enhance soil fertility and environmental health.
Organic farming has been shown to reduce the cost of cultivation and increase yields in the long term. While there may be a temporary reduction in crop yields during the initial transition phase, studies have shown that organic farming can eventually produce comparable or even higher yields than conventional agriculture.
By encouraging organic farming practices, India can reduce chemical runoff into its rivers, improving water quality and mitigating the negative impacts of agricultural practices on the environment.

Prioritize vulnerable populations and ensure equitable access to clean water
India's water crisis is a complex issue with many underlying causes. The country's rivers, which are a vital source of water for millions of people, are severely polluted. Sewage discharged from cities, towns, and some villages is the predominant cause of water pollution in India. The gap between sewage generation and treatment capacity needs to be addressed through increased investment in infrastructure and maintenance.
To prioritize vulnerable populations and ensure equitable access to clean water, several measures can be implemented:
Recognize the Impact on Vulnerable Groups
Understand the disproportionate impact of water pollution and scarcity on vulnerable populations, including women, children, and low-income communities. Women and children often bear the burden of collecting water when families do not have reliable sources, which can impact their education, health, and well-being.
Strengthen Government Initiatives
Support and strengthen government initiatives aimed at providing clean water and sanitation to all citizens. The Government of India's Jal Jeevan Mission, for example, aims to provide piped water supply to every household by 2024. This mission, supported by UNICEF, prioritizes safe and secure water access and aligns with the Sustainable Development Goal (SDG) criteria for safely managed water supply.
Encourage Community-Managed Drinking Water
Promote community-managed drinking water systems, where local communities are empowered to manage their own water supply schemes. This approach has been successful in projects like Jalanidhi I and II, bringing water into village homes and ensuring affordable access for low-income households. Community management fosters a sense of ownership and can lead to more sustainable water utilization.
Improve Water Infrastructure
Invest in water infrastructure development and maintenance, especially in underserved areas. This includes building and maintaining sewage treatment plants and networks of drains to ensure that sewage is treated before reaching rivers and other water sources. The World Bank has supported projects worth $1 billion to set up institutions and build infrastructure to keep the Ganga River clean, addressing the issue of sewage pollution.
Ensure Affordable Access
Make clean water affordable for all, with special consideration for vulnerable and low-income communities. Implement subsidized household-level water connections and maintain affordable tariffs for "lifeline consumption" to ensure that improved water services are accessible to those who need them most.
Collaborate with NGOs and Civil Society
Collaborate with non-governmental organizations (NGOs) and civil society groups, such as WaterAid India, that are working to ensure equitable access to clean water, improved sanitation, and hygiene. These organizations leverage partnerships with government institutions, civil society, and the private sector to create a healthier and more sustainable future for all.

Implement and enforce stringent anti-pollution laws
India has a range of laws in place to prevent and control water pollution, however, the enforcement of these laws is key to their success. The Environment Protection Act of 1986 (EPA) is considered umbrella legislation, filling in gaps in existing laws. The EPA grants regulatory authority to State Pollution Control Boards (SPCB) and the Central Pollution Control Board (CPCB) to establish and enforce effluent standards for factories. The SPCB and CPCB can also test equipment, take samples for analysis, and close defaulting industrial plants.
The Water Act and the Air Act are also relevant, with the latter including a citizen's suit provision. The Indian Constitution includes the right to a clean environment and water under Article 21, Article 48, and Article 51(g). The Indian Penal Code (IPC) also contains provisions to punish those who voluntarily pollute public water sources, with imprisonment or fines, or both.
To strengthen the implementation and enforcement of these laws, the following measures could be considered:
- Increase investment in sewage treatment infrastructure: India's major cities produce a vast amount of sewage daily, and the current treatment capacity is insufficient.
- Strict enforcement of regulations on industrial waste disposal: Industries are responsible for a significant amount of river pollution, and ensuring they adhere to proper waste disposal methods is crucial. The CPCB should actively monitor and penalize industries that directly deposit wastewater into rivers.
- Promote public-private partnerships: Collaboration between the public and private sectors can help raise funds for river rejuvenation projects and ensure effective implementation.
- Encourage local participation: Involving local communities and villages in river rejuvenation efforts is essential for their success, as advocated by water expert Madhav Chitale.
- Improve solid waste management: Implement measures to prevent the dumping of untreated solid waste into rivers and promote recycling and proper waste disposal practices.
