Stop industrial waste and sewage from entering the river
The Ganges River is one of the five most polluted rivers in the world. Every day, 2.9 billion liters of wastewater from sewage, domestic, and industrial sources are dumped directly into the river. This includes toxic industrial waste, which accounts for 20% of the pollution. This waste enters the river untreated, with dangerous chemicals and heavy metals far exceeding safe levels.
To stop industrial waste and sewage from entering the river, the Indian government announced a $4 billion campaign in 2010 to ensure that, by 2020, no untreated municipal sewage or industrial runoff would enter the river. This plan, called Mission Clean Ganga, aims to address the entire Gangetic basin while planning and prioritizing investment. The Supreme Court of India has also been working on the closure and relocation of many industrial plants along the Ganges.
To support these efforts, Common Effluent Treatment Plants (CETP) must be mandatory for all industries that are discharging treated and untreated effluent into the river. These plants should adopt zero-discharge technologies to prevent any waste from entering the river. All industries should also recycle and reuse their treated effluent to meet their industrial process water and irrigation requirements.
In addition to these regulatory measures, public participation is key to sustainable change. Regular and consistent water quality monitoring data should be made available to the public, and social participation in the process of monitoring policies and laws should be encouraged. Industries should be incentivized to use eco-friendly technologies that reduce toxic discharge, with fair warning, capacity building, and training provided to support them in this transition.

Improve water management and conservation
The Ganga River is one of the five most polluted rivers in the world, threatening the health and well-being of over 500 million people who depend on it. To improve water management and conservation in the Ganga River, several comprehensive strategies and initiatives have been proposed and implemented.
One key strategy is to promote massive water conservation and resource management within the Ganga River Basin. This includes implementing rainwater harvesting schemes and encouraging sustainable farming practices such as conservation agriculture, crop rotation, and the use of organic fertilizers. By minimizing pollution from agricultural runoff, this approach helps to protect the river's ecological integrity. Additionally, wastewater from industries can be recycled and reused for non-potable purposes like agriculture, reducing water diversion from vulnerable ecosystems.
Another crucial aspect is the implementation of detailed legislation and policies that prioritize the health of the river and vulnerable populations. This involves addressing sewage waste mismanagement, which accounts for a significant proportion of the river's pollution. The treatment of municipal and industrial wastewater must be improved, and the discharge of toxic industrial effluents must be adequately regulated to prevent further degradation.
The Ganga Action Plan (GAP), launched in 1985, aimed to improve water quality by intercepting, diverting, and treating domestic sewage, as well as preventing toxic and industrial chemical wastes from entering the river. While GAP has had limited success, it has led to intensified efforts for pollution abatement through projects focusing on sewage treatment, river surface cleaning, and rural sanitation.
The National Mission for Clean Ganga (NMCG) and its flagship initiative, the Namami Gange Programme, have also been established to comprehensively address the river's pollution. Under this programme, numerous projects have been sanctioned, including those focused on sewage infrastructure, riverfront development, river surface cleaning, and biodiversity conservation. The programme has made significant investments to improve water management and conservation in the Ganga River Basin.
Furthermore, stakeholders such as the IFC have invested in wastewater treatment plant projects, aiming to reduce the discharge of untreated sewage and mitigate the climate impact on the Sundarbans mangroves. These collaborative efforts have resulted in notable improvements in reducing pollution, restoring biodiversity, and enhancing water quality.

Raise awareness and change behaviours
The Ganga River is one of the most polluted rivers in the world, threatening the health and livelihoods of over 500 million people who depend on it. While the Indian government has made efforts to clean the river, such as the Namami Gange programme, the complexity of the challenge requires integrated and comprehensive solutions. One key aspect is raising awareness and changing behaviours to reduce pollution and protect the river.
One way to raise awareness is through mass media campaigns that educate people about the impact of pollution on the Ganga River and promote eco-consciousness. This includes spreading information about the environmental and health consequences of pollution, such as the accumulation of toxic heavy metals in food sources and the increased risk of waterborne diseases. By understanding the impact of their actions, people may be more inclined to make behavioural changes and become part of the solution.
Another way to raise awareness is by involving various stakeholders, including state and local bodies, in addressing the issues facing the Ganga River. This can be done through training and capacity-building programs that encourage participation and collaboration in finding solutions. For example, providing education and resources to local communities on proper waste management practices can help reduce the amount of waste that ends up in the river.
Additionally, it is essential to address the cultural and religious beliefs that contribute to pollution. Traditional Hindu beliefs hold that cremation on the banks of the Ganga River will cleanse the sins of the deceased. However, this has led to the disposal of partially burnt bodies and funeral waste into the river. By working with religious leaders and communities, alternative practices that are environmentally friendly can be promoted while still respecting cultural traditions.
Raising awareness and changing behaviours also extend to industries and agriculture, which contribute significantly to the pollution of the Ganga River through the disposal of toxic chemicals and heavy metals. Strict legislation and enforcement are necessary to ensure that industries properly treat their waste and effluents before discharge. Additionally, promoting sustainable practices and technologies that reduce the use of harmful chemicals and encourage recycling and reuse can help reduce the pollution load on the river.
Finally, raising awareness among policymakers and government officials is crucial. This includes recognizing the interconnectedness of the issues and the need for comprehensive solutions that address both human health and ecological integrity. By prioritizing vulnerable populations and ensuring their right to a healthy environment, policies can be designed to protect both people and the planet.
