India's Water Pollution: Initiatives And Future Plans

India is facing a water crisis. With 18% of the world's population, it only has access to 4% of its water resources. The country is prone to droughts and flooding, and climate change is only going to exacerbate these issues. Water pollution is a significant problem, with untreated sewage, agricultural runoff, and unregulated small-scale industry contaminating water sources. However, India is taking steps to combat this crisis and improve access to safe water and sanitation for its citizens. For example, Chennai has become the first Indian city to recycle wastewater at scale to meet non-drinking water needs, and the World Bank has supported the government's efforts to bring clean drinking water to rural communities. India is also working to improve water governance and reduce the damage done to groundwater sources.

India's water crisis is exacerbated by a lack of regulation, over-privatisation, neglect, and government corruption

India's water crisis is a complex issue exacerbated by various factors, including a lack of regulation, over-privatisation, neglect, and government corruption.

Lack of regulation and ineffective policies have contributed to the over-exploitation of groundwater sources. For decades, policies have allowed a free-for-all in groundwater development, with farmers provided electricity subsidies to power groundwater pumping. This has led to a significant drop in the water table, up to 4 meters in some areas. The aggressive pumping of groundwater, particularly in rural areas where agriculture is the primary livelihood, has accelerated the depletion of freshwater sources.

Over-privatisation has also played a role in the water crisis. The privatisation of water services has led to unequal access, with the most vulnerable communities, such as those living in poverty, bearing the brunt. Women and children are often responsible for water collection, travelling long distances to access safe water sources. This has been partially alleviated by Water.org, which has empowered millions of people through their WaterCredit solution, providing affordable access to safe water and sanitation.

Neglect and mismanagement of water resources have also exacerbated the crisis. India's water infrastructure has suffered from a lack of investment and proper maintenance, particularly in rural and mountainous areas. The government's indifference to the growing crisis has resulted in inadequate irrigation and water management techniques, further straining water sources.

Lastly, government corruption has hindered efforts to address the water crisis. While the Indian government has made commitments, such as providing tap water connections to every household by 2024, there has been a lack of long-term commitment and proper implementation. The water crisis has significant economic implications, impacting manufacturing jobs and agricultural cultivation, which further underscores the urgency of the situation.

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

India has been facing a water crisis, with annual per capita water availability declining by 75% in the 75 years since its independence. Water pollution is a major environmental issue in India, with untreated sewage being the largest source of water pollution in the country. Other sources of pollution include agricultural runoff and unregulated small-scale industry. Most rivers, lakes, and surface water in India are polluted due to these factors, and this has detrimental effects on both the environment and public health.

The World Bank has been supporting the Indian government's efforts to bring clean drinking water to rural communities. Over the last decade, the World Bank has financed projects worth $1.2 billion that have benefited over 20 million people. One such project is the Uttarakhand Rural Water Supply and Sanitation Project, which helped over 1.57 million people in the state by improving sustainable rural water supply and sanitation services across underserved areas. The project focused on building infrastructure and institutional capacity, including that of village communities, to be resilient to natural disasters such as flash floods, which are common in the mountainous state.

The World Bank has also supported the state government in ensuring that rural families receive a dependable supply of piped water in their homes at affordable prices. The Jalanidhi project, for example, has helped bring water into village homes by putting local communities in charge of managing their own water supply schemes for the first time. This has proven to be a successful model, as community management of water supply systems reduces capital costs for infrastructure and even poor rural residents are willing to pay for assured and safe water supply.

The World Bank has also conducted analytical and advisory activities that have contributed to the dialogue on sector reform. Two major studies were conducted in 2006 and 2008 to understand the evolution of water supply systems in rural India and to identify remaining inefficiencies and barriers. In addition, the World Bank has introduced new systems and technologies that give reservoir managers an accurate picture of the water situation in their region, improving the overall management of water resources in the country.

The World Bank's support for the Indian government's efforts to bring clean drinking water to rural communities is, therefore, multi-faceted and includes financing, knowledge sharing, and capacity building.

Chennai has become the first Indian city to recycle its wastewater at scale

India is facing a severe water crisis, with annual per capita water availability declining by 75% since Independence in 1947. The country is suffering from groundwater depletion, surface water pollution, and the disappearance of water bodies due to encroachment. Water scarcity is exacerbated by erratic monsoon patterns, rapid urbanization, and increasing industrialization.

Chennai, a southern metropolis in India, has become the first Indian city to address this crisis by implementing large-scale water recycling. In 2019, Chennai faced a severe water shortage, and officials declared "Day Zero," bringing the city to a standstill. To address this issue, Chennai took inspiration from Singapore's successful water initiative and began recycling wastewater at scale to meet the non-drinking water needs of its industries.

The city has established two Tertiary Treatment Reverse Osmosis (TTRO) plants, located in Kodungaiyur and Koyambedu, which are the first of their kind in India. These plants have a capacity of 45 million liters per day each and aim to recycle about 20% of Chennai's sewage. By treating sewage and utilizing it for industrial purposes, Chennai is reducing its consumption of freshwater and alleviating the strain on its water resources.

A study by Anna University estimates that by 2050, Chennai can meet up to 50% of its water demands by recycling and reusing its sewage. This initiative has gained global recognition, winning awards such as the Global Water Award and HUDCO's 2019 award for best practices that improve the living environment and city resilience.

While Chennai has taken a significant step towards water conservation, India as a whole continues to struggle with water pollution and scarcity. The World Bank and the Indian government are working together to address these challenges through various projects, including the rejuvenation of the Ganga River and the implementation of groundwater conservation programs.

NGOs, pressure groups, eco-clubs, and citizens' movements are active in their task to clean the river

NGOs, pressure groups, eco-clubs, and citizens' movements are actively working to clean India's rivers. One notable example is the Namami Gange project, which has faced criticism from religious groups and campaigners for failing to meet safety targets. Vishwambhar Nath Mishra, a religious leader and critic of the project, emphasises the importance of the Ganges River in religious practices and the urgent need for potable water quality. He provides scientific parameters for acceptable levels of fecal coliform bacteria, which are indicators of other pathogens. Despite some progress, government schemes have not yet achieved the desired results.

In addition to religious groups, non-profit organisations like Bharat Clean Rivers Foundation (BCRF) are also playing a crucial role in cleaning India's rivers. BCRF has partnered with Ocean Cleanup, a global leader in removing ocean trash, to address plastic pollution in Indian rivers. Their focus is on improving marine ecosystems and biodiversity, starting with Mumbai, to enhance tourism and sustainable fishing. This initiative recognises the urgency of addressing marine plastic pollution, which is predicted to outweigh fish in the world's oceans by 2050.

Moreover, citizens' movements and eco-clubs are taking matters into their own hands. In Chennai, for instance, the city has become the first in India to recycle wastewater at scale to meet non-drinking water needs. Two Tertiary Treatment Reverse Osmosis (TTRO) plants will recycle about 20% of Chennai's sewage, reducing the city's consumption of freshwater. This local initiative demonstrates the commitment of citizens and eco-clubs to tackle water pollution.

Pressure groups are also advocating for policy changes and stricter implementation. They suggest that sewage should be metered, with households and industries charged accordingly, to encourage the reduction of sewage discharge into rivers. Additionally, they propose incentivising farmers to shift to organic cultivation to prevent desertification and ensure food security. These groups recognise that addressing river pollution requires sustainable and efficient public-private partnerships, similar to the successful development of India's road infrastructure.

Overall, the active participation of NGOs, pressure groups, eco-clubs, and citizens' movements is vital in India's efforts to clean its rivers. Their combination of religious, environmental, and practical perspectives drives innovative solutions and holds the government accountable for its commitments. By working together, these groups are making significant strides towards restoring the health of India's river systems.

India's wastewater treatment plant market has been growing annually at a rate of 10-12%

India's water crisis is a critical issue. With 1.3 billion people, and a predicted growth to 1.7 billion by 2050, India is unable to provide safe, clean water to the majority of its population. The country has just 4% of the world's fresh water, and the per capita availability of water has declined by 75% since 1947.

Water pollution is a major environmental issue in India, with untreated sewage being the largest source of water pollution. Other sources include agricultural runoff and unregulated small-scale industry. The majority of government-owned sewage treatment plants are closed most of the time due to poor design, maintenance, and management. As a result, most rivers, lakes, and surface water in India are polluted. The Ganga, India's most iconic river, is facing formidable pressures from rapid urbanization, with over 100 towns and cities pouring sewage into the river.

To tackle this, India's wastewater treatment plant market has been growing annually at a rate of 10-12% since 2005. The United States is the largest supplier of treatment equipment and supplies, with a 40% market share of new installations. With continued investment and reform, it is estimated that India will nearly triple its water treatment capacity by 2015, and treatment capacity supply will match India's daily sewage water treatment requirements by about 2020.

In addition to this, several other projects are aiming to improve water governance in India. The World Bank has been supporting the government's efforts to bring clean drinking water to rural communities, with over $1.2 billion in financing benefiting 20 million people. The World Bank has also been supporting the government's national groundwater program, the Atal Bhujal Yojana, and has helped set up institutions and build infrastructure to keep the Ganga river clean.

At a local level, the state of Maharashtra is making progress in providing safe water and sanitation to its people, and the city of Chennai has become the first Indian city to recycle its wastewater at scale to meet the non-drinking water needs of its industries. The Rivers Narmada and Chambal also run clean, with water fit for consumption.

Technology and reliable data are also playing an increasingly important role in addressing water pollution in India. Machine learning models are being used to build predictive models and improve the scope and frequency of water pollution measurements.
