India's Drinking Water: Polluted And Unsafe?

India, the world's second most populated country, is facing a water crisis. With 18% of the world's population, India only possesses 4% of the world's freshwater. This has led to a severe lack of access to safe drinking water, with 163 million Indians lacking access to it. The water crisis in India is exacerbated by pollution, with industrial discharge, agricultural runoff, untreated sewage, and improper disposal of waste contaminating water sources and making them unfit for human consumption. This has resulted in detrimental effects on both the environment and public health, with waterborne diseases causing illness, hospitalization, and death. Efforts are being made by the Indian government and various organizations to address the issue through stricter regulations, wastewater treatment plants, and community-based initiatives, but the challenge remains daunting.

India's water pollution crisis

India's water crisis is a complex issue with far-reaching consequences for the country's social, environmental, and economic well-being. With 18% of the world's population, India has only 4% of the world's freshwater resources, making it one of the most water-stressed countries globally. The situation is further exacerbated by severe water pollution, which has led to a shortage of clean and safe drinking water for its vast population.

Water pollution in India is primarily caused by untreated sewage, agricultural runoff, and industrial discharge. The country's rapid urbanization and industrialization have placed immense pressure on its water resources, with over 100 towns and cities dumping domestic sewage into rivers like the Ganga, considered holy by Hindus. In addition, industrial activities release various pollutants, including toxic chemicals and heavy metals, into water bodies and groundwater sources. As a result, more than half of India's rivers are highly polluted, and the water is unfit for human consumption, causing detrimental effects on public health and aquatic ecosystems.

The health impacts of contaminated water are significant, with waterborne diseases such as cholera, typhoid, and hepatitis causing illness, hospitalization, and even death among those exposed to polluted water sources. According to a Lancet study, water pollution caused over half a million premature deaths in India in 2019 alone. Additionally, groundwater contamination due to agricultural runoff affects millions who depend on groundwater for drinking, with high levels of contaminants such as arsenic and fluoride causing severe health issues.

The water crisis in India is also driven by a lack of infrastructure and inadequate wastewater management. India's erratic monsoon patterns, which provide most of the country's water replenishment, further complicate the issue. The unpredictable nature of droughts and floods caused by climate change is expected to increase, impacting agricultural productivity and the socio-economics of affected areas. Furthermore, the country's growing middle class raises the demand for clean, safe water, creating a dichotomy between different populations vying for the same limited resource.

Efforts to address water pollution in India have been made by the government, NGOs, and community organizations through stricter regulations, wastewater treatment plants, and community-based initiatives. However, the country's complex bureaucracy and lack of coordination among various ministries and departments have hindered progress. While projects supported by the World Bank and innovative schemes, such as Chennai's wastewater recycling initiative, have shown promise, there is still a long way to go to ensure access to clean and safe water for all Indians.

The impact of industrial and agricultural activities

India's water crisis is a complex issue with many contributing factors, including industrial and agricultural activities. With 18% of the world's population, India has only 4% of the world's freshwater resources, making it one of the most water-stressed countries. The country's rapid industrialization and agricultural practices have severely impacted its water quality and availability, posing significant environmental, health, and economic challenges.

Industrial Activities

Industrial wastewater discharge is a major source of water pollution in India. The country's industrialization has resulted in the release of untreated or poorly treated effluents into water bodies, including rivers, lakes, and groundwater. This wastewater often contains high levels of pollutants, such as heavy metals, chemicals, and toxic substances. The lack of regulation and enforcement in the industrial sector has exacerbated the problem, with many industries disposing of their waste improperly. However, it is important to note that the government has initiated several programs, such as Zero Liquid Discharge (ZLD), to encourage industries to adopt better wastewater treatment processes.

Agricultural Activities

Agricultural practices, particularly the overuse of pesticides and fertilizers, contribute significantly to water pollution in India. Excessive pesticide use, including banned substances such as Dichlorodiphenyltrichloroethane (DDT), Aldrin, and Hexachlorocyclohexane (HCH), contaminates water sources and poses risks to both human health and aquatic ecosystems. Additionally, agricultural runoff containing fertilizers and other chemicals leads to the eutrophication of water bodies, creating "dead zones" where aquatic life cannot survive.

Combined Impacts

The combination of industrial and agricultural activities intensifies the water pollution problem in India. When untreated industrial wastewater mixes with agricultural runoff, it creates a toxic cocktail of pollutants that are extremely harmful to both the environment and public health. This contaminated water leads to the spread of waterborne diseases, including cholera, typhoid, and hepatitis, causing illness and even death among the population. The economic consequences are also significant, with reduced agricultural yields and revenues, increased health care costs, and a decline in tourism and related industries.

Addressing the Issue

Recognizing the severity of the water crisis, the Indian government, supported by organizations like the World Bank, has implemented various initiatives to improve water management and reduce pollution. These include the National Water Policy, community-led groundwater management programs like the Atal Bhujal Yojana, and the rejuvenation of major rivers like the Ganga. Additionally, there is a growing focus on encouraging the reuse and recycling of treated wastewater for agricultural and industrial purposes, reducing the strain on freshwater resources.

Water scarcity and the monsoon's influence

India, the world's second most populated country, is facing a water crisis. It has 18% of the world's population but only 4% of its water resources, making it one of the most water-stressed countries. This crisis affects hundreds of millions of people, with severe consequences for the ecosystem and agriculture.

Monsoons play a crucial role in India's water availability. The South-West monsoon provides approximately 80% of the country's rainfall, while the North-East monsoon contributes 10-20%. However, the effects of climate change on these monsoon seasons are causing a decrease in rainfall. In recent years, monsoons have become more sporadic, shorter, and less predictable, leading to reduced total precipitation. For example, in 2018, the South-West monsoon was delayed by 10 days, causing a 36% decrease in rainfall compared to the 50-year average. This delay led to extreme water shortages in many major cities.

The erratic nature of monsoons, with some years experiencing drought and others excessive rainfall, has severe implications for water scarcity and agriculture. Drought conditions can lead to crop failures, farmer suicides, and economic distress in rural areas. Conversely, excessive rainfall can result in flooding, which also negatively impacts agricultural productivity and contributes to water pollution.

The impact of monsoon variability is further exacerbated by India's heavy reliance on agriculture, which accounts for 78% of the country's water usage. Groundwater is a critical source for irrigation, and its depletion has severe consequences for agricultural productivity and food prices. In states like Punjab, rampant tubewell irrigation has caused a drastic drop in the groundwater table. Additionally, inefficient agricultural practices and excessive groundwater extraction have depleted vital water sources.

To address the water crisis, India needs to adopt sustainable water management practices, improve water treatment and infrastructure, promote water conservation, and ensure equitable distribution. Initiatives like the Atal Bhujal Yojana, India's largest community-led groundwater management program, are helping to improve rural livelihoods and build resilience in states with high groundwater depletion. However, the country's rapid urbanization and industrialization, along with population growth, continue to strain water resources, underscoring the urgency of effective water governance.

Government initiatives and challenges

India's water crisis is a complex issue that requires concerted efforts from the government and various stakeholders to address effectively. The country faces challenges such as water scarcity, pollution, and unequal distribution, which have far-reaching consequences for its people, economy, and environment.

The Indian government has recognised water security as a critical issue and has taken several initiatives to improve the situation. One notable effort is the National Water Quality Monitoring Network, established by the Central Pollution Control Board. This network comprises 1,429 monitoring stations across 28 states and Union Territories, routinely analysing water samples from various sources for various parameters to ensure water quality.

The government has also been working to improve sewage treatment infrastructure. Despite challenges with existing plants, including design flaws, maintenance issues, and electricity supply problems, India has seen an annual growth rate of 10-12% in its wastewater treatment plant market since 2005. With continued government reform and investment, it was estimated that the country would nearly triple its water treatment capacity by 2015.

Additionally, the government has promoted the Zero Liquid Discharge (ZLD) process to address industrial pollution, a water treatment method that eliminates liquid waste from highly polluting industries. While installation costs and technical limitations are hurdles, some large industrial plants, such as Unilever and P&G, have successfully implemented ZLD.

The World Bank has also been instrumental in supporting the Indian government's efforts. Since 2011, the bank has been involved in projects worth $1 billion to rejuvenate the iconic Ganga River, which faces immense pollution pressure from rapid urbanisation. The bank has also financed projects like the Uttarakhand Rural Water Supply and Sanitation Project, benefiting over 1.57 million people by improving sustainable water supply and sanitation services in underserved areas.

Other initiatives include the government's Jal Jeevan Mission, which aims to provide tap water connections to every household by 2024, and partnerships with organisations like Water.org, which has empowered over 29.7 million people with access to safe water or sanitation through its WaterCredit solution.

However, challenges remain. India's water security is threatened by over-extraction of groundwater, and the country is highly dependent on erratic monsoons for its water requirements, a situation that climate change will likely exacerbate. Moreover, the country needs to invest in water infrastructure, such as dams and reservoirs, to improve storage capacity and distribution. Changing behaviours to reduce water usage and waste, especially in the face of water scarcity, is also critical.

Access to clean water in rural and urban areas

India is facing a water crisis. With 18% of the world's population, it only has 4% of its freshwater resources, making it one of the most water-stressed countries in the world. The situation is critical, with severe regulation issues, over-privatisation, neglect, and government corruption, leading to a severe lack of access to safe drinking water.

Access to clean water in rural areas

In rural areas, groundwater from over 30 million access points supplies 85% of drinking water. However, this is being depleted due to overexploitation, with the water table falling drastically in some areas. The World Bank has been supporting the government's efforts to bring clean drinking water to rural communities, with projects totalling $1.2 billion, benefitting over 20 million people. For example, the Uttarakhand Rural Water Supply and Sanitation Project helped over 1.57 million people by improving sustainable water supply and sanitation services.

In 2015, India achieved 93% coverage of access to improved water supply in rural areas. However, with the shift to Sustainable Development Goals, the new baseline estimates that less than 49% of the rural population is using safely managed drinking water. Since 2019, the Jal Jeevan Mission has aimed to provide piped water supply to every household in the country by 2024, with coverage of functional household tap connections in rural areas increasing from 17% to over 49%.

Access to clean water in urban areas

Most urban households receive water for a few hours a day at most, and often only on a few days a week. Major cities in India produce 38,354 million litres of sewage per day, but the urban sewage treatment capacity is only 11,7786 million litres, leading to severe river pollution.

Chennai has become the first Indian city to recycle wastewater at scale to meet the non-drinking water needs of its industries. The Ganga River, India's most iconic river, is facing formidable pressures of rapid urbanization, with over 100 towns and cities pouring sewage into it. The World Bank has been supporting the government's efforts to rejuvenate the river since 2011, with projects worth $1 billion.
