India's Battle Against Polluted Water: Strategies And Challenges

Water pollution is a significant issue in India, with an estimated 70% of surface water unfit for consumption. The country's rapid urbanization, industrialization, and agricultural activities have led to the contamination of both surface and groundwater sources. To address this crisis, India has been working on implementing stricter regulations, wastewater treatment plants, awareness campaigns, and community-based initiatives. The Indian government, NGOs, and community organizations are making efforts to tackle water pollution and ensure access to clean and safe water for its citizens. While progress has been made, there is still a long way to go to effectively combat water pollution and meet the water needs of India's vast population.

India's water bodies are getting toxic as the country grows and urbanises

India's water crisis is a critical issue. With 18% of the world's population, India has only 4% of its water resources, making it one of the most water-stressed countries globally. As India grows and urbanises, its water bodies are becoming increasingly toxic. It is estimated that around 70% of surface water in India is unfit for consumption, creating a severe public health crisis.

The primary source of water pollution in India is untreated sewage, with major cities producing 38,354 million litres of sewage per day, while the urban sewage treatment capacity is only 11,786 million litres. This has led to severe pollution in many Indian rivers, including the Ganges, Yamuna, and Sabarmati, which are contaminated with a deadly mix of hazardous and organic pollutants. In addition to sewage, industrial waste and agricultural runoff are also significant contributors to water pollution in India.

The Indian government, along with NGOs and community organizations, is making efforts to address water pollution through stricter regulations, wastewater treatment plants, awareness campaigns, and community-based initiatives. The World Bank has been supporting the government's efforts since 2011, with projects worth $1 billion to help manage and clean the Ganga River. Additionally, Chennai has become the first Indian city to recycle wastewater at scale to meet the non-drinking water needs of its industries.

However, there are still significant challenges to overcome. There is a lack of coordination among the various ministries and departments responsible for water management, and corruption and neglect have hindered progress. Furthermore, industrial activities continue to pose a severe threat to water bodies, with many industries failing to implement proper water disposal techniques or bypassing regulations. As a result, groundwater contamination is impacting both rural and urban areas, and pollution-induced migration is on the rise.

To effectively combat water pollution and ensure access to clean and safe water for all, India needs to implement robust policies, improve water governance, and increase investment in water treatment infrastructure. Additionally, promoting sustainable practices, such as updated irrigation techniques and rainwater harvesting, can help reduce the strain on freshwater sources.

The World Bank has supported the Indian government's efforts to bring clean drinking water to rural communities

India's water crisis is a critical issue, with the country's rapid population growth outpacing its ability to provide safe, clean water to its citizens. The World Bank has been supporting the Indian government's efforts to bring clean drinking water to rural communities, recognizing the importance of improving access to water and sanitation services.

One of the key initiatives undertaken by the World Bank is the Uttarakhand Rural Water Supply and Sanitation Project, which received funding of $1.2 billion. This project focused on improving sustainable water supply and sanitation services in the state of Uttarakhand, where the mountainous terrain posed significant challenges to water infrastructure development and maintenance. The project's impact was felt by over 1.5 million people, who gained improved access to clean water and sanitation facilities.

The World Bank has also been instrumental in promoting community-led water management initiatives. Through the Atal Bhujal Yojana program, implemented across seven Indian states, local communities are empowered to understand their water availability and usage patterns, enabling them to budget their water usage effectively. This program is the world's largest community-led groundwater management initiative and has played a crucial role in conserving this valuable resource.

In addition, the World Bank has supported hydrology projects that introduce new systems and technologies to enhance water resource management. These projects provide reservoir managers with accurate data and information, enabling them to make informed decisions and improve overall water management in the country. The Bank has also conducted analytical and advisory activities, collaborating with institutions like the Massachusetts Institute of Technology, to address the challenges of water supply systems in rural India.

Furthermore, the World Bank has approved a $363 million loan to the southern Indian state of Karnataka to improve water supply to 2 million rural households. This initiative aims to provide piped water connections to every rural household in the state, ensuring a continuous and reliable water supply. The program also prioritizes gender parity, recognizing that women bear the burden of fetching water, and seeks to enhance their health, education, and job opportunities.

The Central Pollution Control Board reported that as of 2016, 746 industries directly deposited wastewater into the Ganga

Water pollution is a significant issue in India, with around 70% of surface water unfit for consumption. The country's rivers, lakes, and surface water are polluted due to untreated sewage, industrial waste, and solid waste. The Central Pollution Control Board (CPCB) reported that, as of 2016, 746 industries directly deposited wastewater into the Ganga, India's largest river. This wastewater contains heavy metals such as lead, cadmium, copper, chromium, zinc, and arsenic, which are harmful to both aquatic life and human health.

The Ganga is considered sacred in Hinduism, and millions of people bathe in it every year to cleanse themselves of sins. However, this river is one of the most polluted in India, along with the Yamuna, Gomti, Ghaghara, Chambal, Mahi, Vardha, and Godavari. The pollution in the Ganga comes from various sources, including industrial waste, agricultural runoff, and untreated sewage. There are many industrial cities on the banks of the river, such as Kanpur, Prayagraj, Varanasi, and Patna, as well as tanneries, chemical plants, textile mills, distilleries, slaughterhouses, and hospitals. These cities and facilities dump untreated waste into the river, contributing to its high levels of pollution.

The Indian government has taken several initiatives to address the issue of industrial pollution in the Ganga. In 2010, the government announced a $4 billion campaign to ensure that no untreated municipal sewage or industrial runoff enters the river by 2020. The National Mission for Clean Ganga (NMCG) was established in 2016 to comprehensively clean the Ganga and its tributaries. The Namami Gange Programme, launched in 2014, allocated a budget of ₹20,000 crore for pollution abatement, conservation, and rejuvenation of the river. The Ganga Action Plan (GAP), launched in 1985, aimed to improve water quality through the interception, diversion, and treatment of domestic sewage and the prevention of toxic and industrial chemical wastes from entering the river.

Despite these efforts, the Ganga remains severely polluted. The problem is not only due to industrial waste but also to the lack of sufficient treatment capacity and the poor maintenance of existing sewage treatment plants. India's wastewater treatment plant market has been growing annually at a rate of 10-12% since 2005, and the government has encouraged the implementation of zero liquid discharge (ZLD) technology at large industrial plants. However, the high installation costs and challenges in processing large amounts of dissolved solids in wastewater deter many industrial plants from adopting this technology.

To address the water crisis in India effectively, a combination of solutions is necessary. This includes improving water governance, investing in infrastructure, adopting sustainable practices, and utilizing modern technologies such as machine learning for better data collection and decision-making. Additionally, community participation and decentralized water management approaches can also play a crucial role in conserving and wisely utilizing water sources.

The Indian government, NGOs and community organisations are addressing water pollution through stricter regulations, wastewater treatment plants, awareness campaigns and community-based initiatives

India's water crisis is a critical issue. With 18% of the world's population, India only has access to 4% of its freshwater resources, making it one of the most water-stressed countries globally. The situation is exacerbated by erratic monsoon rains, climate change, and increasing urbanisation, which all contribute to the pollution of water sources.

The Indian government, NGOs, and community organisations are addressing water pollution through a variety of measures:

Stricter Regulations

The Indian government has implemented laws such as the Environment Protection Act of 1986 and the Water (Prevention and Control of Pollution) Act of 1974. These acts mandate that industrial units and local bodies install Effluent Treatment Plants (ETPs) to safely recycle wastewater. However, enforcement of these regulations remains a challenge, with many factories bypassing this requirement, leading to significant water contamination.

Wastewater Treatment Plants

The Indian wastewater treatment plant market has been growing annually at a rate of 10-12% since 2005. With the United States as the largest supplier of treatment equipment, India was estimated to nearly triple its water treatment capacity by 2015. Chennai, for example, has become the first Indian city to recycle its wastewater at scale to meet the non-drinking water needs of its industries.

Awareness Campaigns

NGOs, pressure groups, eco-clubs, and citizens' movements have been actively campaigning to clean up highly polluted rivers like the Ganges and the Yamuna. These campaigns aim to raise awareness about the health risks and environmental impacts of water pollution, encouraging community participation and decentralised water management.

Community-based Initiatives

Community-based initiatives focus on improving water governance and promoting sustainable practices. This includes teaching farmers updated irrigation techniques, such as drip irrigation, and encouraging rainwater harvesting. Additionally, common sense practices and training can help reduce the damage to groundwater sources, and modern sanitation policies can conserve and wisely utilise water sources.

While efforts are being made, there is still a long way to go to effectively combat water pollution and ensure access to clean and safe water for all Indians.

Sewage discharged from cities, towns and some villages is the predominant cause of water pollution in India

Sewage discharged from cities, towns, and some villages is the predominant cause of water pollution in India. The country's major cities produce 38,354 million litres per day (MLD) of sewage, but the urban sewage treatment capacity is only 11,786 MLD. This has resulted in a large number of Indian rivers being severely polluted due to the discharge of untreated domestic sewage. The problem is exacerbated by the fact that many of the government-owned sewage treatment plants remain closed due to improper design, poor maintenance, or a lack of reliable electricity supply.

The pollution of Indian rivers by sewage has severe consequences for both the environment and public health. Contaminated water is a significant cause of waterborne diseases such as cholera, typhoid, and hepatitis, which can lead to illness, hospitalization, and even death. It also contributes to environmental degradation, as pollutants like heavy metals, pesticides, and industrial chemicals harm aquatic ecosystems, disrupt the balance of ecosystems, and lead to a decline in fish and other aquatic organisms, loss of biodiversity, and degradation of water quality.

To address this issue, India has been working to increase its investment in sewage treatment plants and electricity infrastructure development. Since 2005, the Indian wastewater treatment plant market has been growing annually at a rate of 10 to 12 percent. It was estimated that by 2015, India would nearly triple its water treatment capacity, and by 2020, its treatment capacity supply would match its daily sewage water treatment requirements. Additionally, approximately 815 sewage treatment plants (STPs) have been planned or are under development in the last six years, increasing the percentage of urban sewage treated from 37% in 2015 to 50% in 2021.

However, despite these efforts, water pollution remains a critical issue in India. As of 2012, Delhi's sacred Yamuna River contained 7,500 coliform bacteria per 100cc of water, and it is estimated that around 70% of surface water in India is unfit for consumption. The country's complex bureaucracy and fragmented responsibility for managing water issues across multiple ministries and departments have hindered effective interventions. As India continues to grow and urbanize, it is crucial that sustainable practices and modern sanitation policies are implemented to conserve and wisely utilize water sources.
