Drinking water in India is extracted from multiple sources across the country.
North India: In the arid regions of North India, groundwater is often the only source of drinking water. India possesses about 432 bcm of groundwater replenished yearly from rain and river drainage, but only 395 bcm are usable, out of which, about 82% goes to irrigation and agricultural purposes. Shimla is facing a major water crisis with limited access to water through tankers for drinking and livelihood purposes. As a result, schools remained closed and tourists were asked to stay away.
West India: The quest for access to clean water sources has led to extensive groundwater extraction in West India. Maximum depletion has been witnessed around Rajasthan, Haryana, Punjab, Gujarat, Telangana and Maharashtra. Latur area of Maharashtra witnessed drought in 2017, however, very little has changed on the ground. Sugarcane cultivation which is heavily dependent on groundwater for irrigation has not seen any major policy overhaul, neither has micro-irrigation practises such as drip or sprinklers been adopted.
Vows of drought prone Krishna basin
Inter-basin transfer is the massive diversion of water from the dry and drought-prone Krishna river basin in western Maharashtra to the high-rainfall Konkan region of coastal Maharashtra. While people in the Krishna basin suffered from recurring droughts and increasing difficulties in accessing safe drinking water, water was been diverted from to generate power for the city of Mumbai. Although in May 2016, Mumbai High Court announced a reversal of this inter-basin transfer, but no steps have been taken in that direction.
South India: Major cities including Chennai, Mysuru and Bengaluru are going through severe drinking water scarcity affecting both day-to-day life and Tourism. The scarcity is attributed to non functional bore-wells, inefficient water management, erratic weather patterns and insufficient supply to meet the excessive needs.
Living without water in Chennai
Following failure of monsoon, depleted groundwater table and dry reservoirs have led to Chennai facing its worst water crisis. The local bodies are facing challenges in supplying drinking water on a daily basis and residents rush with buckets to store water from tankers for entire week. Due to severe water shortage for drinking and livelihood purposes, the city’s everyday life has come to a standstill, schools and hospitals have been badly affected, and industrial sectors have been slowed down. Dry reservoirs and major sources of water are making Chennai dependent on other water sources, such as stone quarries, agriculture wells, Neyveli corporation mines, etc
The State government plans to bring 10 million litres of water from Vellore by rail wagons and from Veeranam lake, which gets Cauvery water from the Mettur dam. There are also plans to write to the Kerala government requesting it to supply 2 MLD every day. Hence, neighboring states’ cooperation along with Central assistance holds critical importance in bringing the city’s water adequacy back to its optimal level.
Bengaluru’s Imminent Water Crisis – A victim of misplaced priorities
A city once known for its lakes, Bengaluru’s sources of safe drinking water have drastically shrunk. Absence of any word of caution from the Cauvery Tribunal has made matters worse. Instead, precious water was transferred from small towns and villages to this megacity hailed globally for its impressive strides in the IT and start-up space. A recent report highlighted that Bengaluru could be doomed, like Cape Town in South Africa, to face the threat of running out of drinking water. Bengaluru, despite not being in the Cauvery basin, has been awarded a total of 4.75 TMC (thousand million cubic feet) of water annually to meet the drinking water needs of its burgeoning urban population
East India: Although relatively less severe than North or West India, the drinking water sources in North Bihar, Jharkhand and West Bengal have also started to witness rapid decline. An estimated 5 million people are likely to be consuming water with concentrations of Arsenic greater than the national standard of 50µg/l, principally in West Bengal.
India is clearly reeling under a sustained water crisis that shows no signs of abating. In this context, NITI Aayog’s Composite Water Management Index Report highlights the performance of major cities and ranked the states based on their water management capacity.
NITI Aayog’s Composite Water Management Index Report - Performance of the states
India states have performed averagely on providing safe drinking water. As per the report, Gujarat topped the list in water management, closely followed by Madhya Pradesh and Andhra Pradesh. However, the lowest performers such as UP, Haryana, Bihar and Jharkhand are home to nearly half of India’s population. While Jharkhand and Rajasthan may have scored low, they have made remarkable improvements when compared over two years.
As per the Census 2011, Punjab is ranked the highest based on the percentage of households with access to safe drinking water while Kerala has the worst rank with 33.5% households having access.
Data from the World Bank also highlights India’s plight:
Let us now analyse the sources of drinking water in India and the reasons for shortage of drinking water
Some of the crucial issues faced by the water sector in India include
Water disputes have a potential impact on the overall economy, socio-cultural fabric, political stability, and security of not only the regions in which they occur, but also affect the entire country. However, the current solutions treat only the symptoms and not the root cause of the problem. Inter-State water Disputes Amendment Bill, 2017 has been introduced to speed up the dispute resolution process. As per the bill, Single Permanent Tribunal is to be set up which will have multiple benches.
3. Pollution: The quality of drinking-water is a powerful environmental determinant of health. Water pollution has reached an alarming level in India and has contributed to water scarcity by polluting freshwater resources, thereby limiting options.
River Pollution: Despite Namami Gane, water quality of Ganga continues to worsen. The waters of the Yamuna, Ganga and Sabarmati flow the dirtiest with a deadly mix of pollutants both hazardous and organic. India’s rivers have high fluoride content and are also contaminated by antibiotics, beyond the permissible limit of 1.5 ppm, which affects 66 million people nationwide. The Ganga river basin that covers 26.3% of India’s Geographic area cannot be used for any purpose, including drinking, cooking or bathing. As per the World Water Development Report, 2019, it has been revealed that coliform bacteria and biochemical oxygen demand (BOD) have increased significantly in the Ganga river Because the rivers are too polluted to drink and the government is unable to deliver freshwater, many urban dwellers are turning to groundwater, leading to its rapid depletion.
Groundwater (GW) Pollution: India is the largest consumer of GW in the world. As per the Department of Drinking Water and Sanitation (DDWS) nearly 90% of the rural water supply is from GW sources. However, high levels of Arsenic and Fluoride are found in the states of UP where around 78% of population lives in rural areas and are dependent on GW for drinking, cooking and irrigation. Government data revealed that over 45 million are affected with groundwater contaminated with fluoride, arsenic, iron, salinity, nitrate and heavy metal. The World Water Development Report has revealed that India extracts almost one fourth of total groundwater extracted globally
Apart from rivers and ground water, many other water sources are contaminated with both bio and chemical pollutants, and over 21% of the country's diseases are water-related. Recently, in February 2019, a report from International Centre for Integrated Mountain Development (ICIMOD) stressed that India, Bangladesh, Pakistan, and China together account for more than 50% of the world’s groundwater withdrawals.
4. Inter-sectoral conflicts: Reliability on water to cool the power plants is one of the largest sources of water withdrawals. Water demand in both Agriculture and Power sector is set to increase tremendously in the coming years.
5. Inefficiency and lack of infrastructure: Water storage infrastructure in India remains one of the lowest in the world. There is also a marked absence of adequate number of well-equipped and functioning sewage treatment plants
6. Climate-Change: Erratic distribution of rainfall, often leading to floods and drought impact drinking water supply. Future predictions include worsening of the situation due to a disturbed hydrological cycle and regional climatic variability.
7.Lack of local Community Participation: Policies and systems are designed and constructed with little participation from local communities.
A WaterAid report named State of the World’s Water 2018, ranked India on the top of 10 countries in the world with 163.1 million inhabitants living without access to safe water close to home.
The global commitment to safe water for all is further demonstrated through the Sustainable Development Goal (SDG) 6 target to achieve universal and equitable access to safe and affordable drinking-water for all.
Privatization of water - World Bank and IMF have suggested privatization of water, based on multiple successful examples of water privatization in different parts of the world, including Gulf countries, Latin American as well as European countries. However, India has not formally considered this idea nor there has been any private sector regulation act or rules to regulate the functioning of the private sector. In this context, National Water Framework Law (NWFL) states that, “water is the common heritage of the people of India; an inseparable part of a people’s landscape, society, history and culture; and in many cultures, a sacred substance, being venerated in some as a divinity”. Such a resource therefore, must never be privatized. Private extraction of groundwater happened in a competitive race to get water from greater and greater depths. Thus, when groundwater is treated as a private resource, it raises a serious issue of destructive competitive extraction. A classic example is that of a soft drinks giant depriving the people of gram panchayat Plachimada in Kerala access to drinking water.
For the drinking water to be of greatest purity, every government enforces standards which classify certain qualities of water as usable and the others as non usable. Indian government has recognized these standard guidelines and put them as a part of legal framework. (Indian Standard Drinking Water Specification (BIS 10500: 1991). UNICEF is also supporting GOI programs on arsenic and fluoride mitigation. National Water Policy also clearly establishes that provision to provide adequate and assured safe drinking water is of utmost priority in the country.
Waterman of India
Ramon Magsaysay awardee Rajinder Singh is a well known water conservationist and environmentalist. He is credited with harvesting rain water for drinking and domestic purposes by building check dams in Alwar and nearby districts of Rajasthan. The idea was to revive the use of traditional technology of Johad, an ancient water conservation technique to replenish the water sources. Johad is a concave structure that collects and stores water throughout the year for drinking purposes by humans and cattle. It is the successful implementation of this ancient innovation that earned him the name 'Jal Purush' or the 'Waterman of Rajasthan'. The sincere efforts of ‘Waterman’ for eradicating drinking water scarcity in the rural areas of Rajasthan inspired many NGOs within the country and abroad. The transformation was visible and long term. Now, women need not walk for miles to fetch water, neither do men have to leave their homes for work, as the land under cultivation in villages have increased manifold and farm incomes have been on a rise. He also played an instrumental role in revitalization of five rivers that had gone dry for long time.
Bunker Roy – A mix of Technology and Tradition
Bunker Roy is an Indian social activist and educator who founded the Barefoot College. It is based in Tilonia, which is a small village in Rajasthan. What makes this college unique is that it believes in identifying and using skills, knowledge and practical experience of ordinary people in the community itself to provide for basic needs such as drinking water. The College takes men, women and children who are illiterate and semi-literate from the lowest castes, and from the most remote and inaccessible villages in India, and trains them at their own pace to become “barefoot” water and solar engineers.
A hundred year old traditional method to collect rain water through roofs with low cost materials came to the rescue. Economically it is cheaper and the village committee could be empowered to control and distribute the water without being dependent on the outside for any technical, human and financial resource. The college confidently rejects the outside professionals and does not believe in technology that deprives people of their jobs, increases dependency and leads to exploitation. They believe that the mindset of the technological engineers is that problems of water shortage and drinkability can only be solved if expensive and deep well drilling rigs exploit the ground water or pump water from a permanent water source through pipes. However, people of the Tilonia village rejected the idea and instead resorted to simpler cost effective solutions. The college’s staggering achievements include regular piped water supply systems to atleast 10 villages around Tilonia designed and implemented entirely by the local people.
Ralegan Siddhi - A Case Study
Raleghan Siddhi is in a drought-prone and rain-shadowed area of India which faced a severe water crisis that resulted in people having to struggle to find drinking water during part of the year. IN 1975, Anna Hazare who had once lived in the village, returned, determined to improve the situation of the country. He began to involve the community and especially the youth. In order to bring back water, he undertook projects with the villagers to construct nalla bunds, install boreholes and hand-pumps to provide drinking water. The village does not any longer have to worry about having drinking water year round, and the woman no longer have to walk long distances to fetch water.
