Yesterday, Members of Parliament in Lok Sabha discussed the situation of drought and drinking water crisis in many states. During the course of the discussion, some MPs also raised the issue of ground water depletion. Last month, the Bombay High Court passed an order to shift IPL matches scheduled for the month of May out of the state of Maharashtra. The court cited an acute water shortage in some parts of the state for its decision. In light of water shortages and depletion of water resources, this blog post addresses some frequently asked questions on the extraction and use of ground water in the country. Q: What is the status of ground water extraction in the country? A: The rate at which ground water is extracted has seen a gradual increase over time. In 2004, for every 100 units of ground water that was recharged and added to the water table, 58 units were extracted for consumption. This increased to 62 in 2011.[1] Delhi, Haryana, Punjab and Rajasthan, saw the most extraction. For every 100 units of ground water recharged, 137 were extracted. In the recent past, availability of ground water per person has reduced by 15%. In India, the net annual ground water availability is 398 billion cubic metre.[2] Due to the increasing population in the country, the national per capita annual availability of ground water has reduced from 1,816 cubic metre in 2001 to 1,544 cubic metre in 2011. Rainfall accounts for 68% recharge to ground water, and the share of other resources, such as canal seepage, return flow from irrigation, recharge from tanks, ponds and water conservation structures taken together is 32%. Q: Who owns ground water? A: The Easement Act, 1882, provides every landowner with the right to collect and dispose, within his own limits, all water under the land and on the surface.[9] The consequence of this law is that the owner of a piece of land can dig wells and extract water based on availability and his discretion.[10] Additionally, landowners are not legally liable for any damage caused to water resources as a result of over-extraction. The lack of regulation for over-extraction of this resource further worsens the situation and has made private ownership of ground water common in most urban and rural areas. Q: Who uses ground water the most? What are the purposes for which it is used? A: 89% of ground water extracted is used in the irrigation sector, making it the highest category user in the country.[3] This is followed by ground water for domestic use which is 9% of the extracted groundwater. Industrial use of ground water is 2%. 50% of urban water requirements and 85% of rural domestic water requirements are also fulfilled by ground water. 
The main means of irrigation in the country are canals, tanks and wells, including tube-wells. Of all these sources, ground water constitutes the largest share. It provides about 61.6% of water for irrigation, followed by canals with 24.5%. Over the years, there has been a decrease in surface water use and a continuous increase in ground water utilisation for irrigation, as can be seen in the figure alongside. [4] Q: Why does agriculture rely most on ground water? A: At present, India uses almost twice the amount of water to grow crops as compared to China and United States. There are two main reasons for this. First, power subsidies for agriculture has played a major role in the decline of water levels in India. Since power is a main component of the cost of ground water extraction, the availability of cheap/subsidised power in many states has resulted in greater extraction of this resource.[5] Moreover, electricity supply is not metered and a flat tariff is charged depending on the horsepower of the pump. Second, it has been observed that even though Minimum Support Prices (MSPs) are currently announced for 23 crops, the effective price support is for wheat and rice.[6] This creates highly skewed incentive structures in favour of wheat and paddy, which are water intensive crops and depend heavily on ground water for their growth. It has been recommended that the over extraction of ground water should be minimized by regulating the use of electricity for its extraction.[7] Separate electric feeders for pumping ground water for agricultural use could address the issue. Rationed water use in agriculture by fixing quantitative ceilings on per hectare use of both water and electricity has also been suggested.[8] Diversification in cropping pattern through better price support for pulses and oilseeds will help reduce the agricultural dependence on ground water.[6] [1] Water and Related Statistics, April 2015, Central Water Commission, http://www.cwc.gov.in/main/downloads/Water%20&%20Related%20Statistics%202015.pdf.

In Budget Session 2018, Rajya Sabha has planned to examine the working of four ministries. The Ministry of Drinking Water and Sanitation is one of the ministries listed for discussion. In this post, we look at the key schemes being implemented by the Ministry and their status.
What are the key functions of the Ministry of Drinking Water and Sanitation?
As per the Constitution, supply of water and sanitation are state subjects which means that states regulate and provide these services. The Ministry of Drinking Water and Sanitation is primarily responsible for policy planning, funding, and coordination of programs for: (i) safe drinking water; and (ii) sanitation, in rural areas. From 1999 till 2011, the Ministry operated as a Department under the Ministry of Rural Development. In 2011, the Department was made an independent Ministry. Presently, the Ministry oversees the implementation of two key schemes of the government: (i) Swachh Bharat Mission-Gramin (SBM-G), and (ii) National Rural Drinking Water Programme (NRDWP).
How have the finances and spending priorities of the Ministry changed over time?
In the Union Budget 2018-19, the Ministry has been allocated Rs 22,357 crore. This is a decrease of Rs 1,654 crore (7%) over the revised expenditure of 2017-18. In 2015-16, the Ministry over-shot its budget by 178%. Consequently, the allocation in 2016-17 was more than doubled (124%) to Rs 14,009 crore.
In recent years, the priorities of the Ministry have seen a shift (see Figure 1). The focus has been on providing sanitation facilities in rural areas, mobilising behavioural change to increase usage of toilets, and consequently eliminating open defecation. However, this has translated into a decrease in the share of allocation towards drinking water (from 87% in 2009-10 to 31% in 2018-19). In the same period, the share of allocation to rural sanitation has increased from 13% to 69%.
What has been the progress under Swacch Bharat Mission- Gramin?
The Swachh Bharat Mission was launched on October 2, 2014 with an aim to achieve universal sanitation coverage, improve cleanliness, and eliminate open defecation in the country by October 2, 2019.
Expenditure on SBM-G: In 2018-19, Rs 15,343 crore has been allocated towards SBM-G. The central government allocation to SBM-G for the five year period from 2014-15 to 2018-19 has been estimated to be Rs 1,00,447 crore. Of this, up to 2018-19, Rs 52,166 crore (52%) has been allocated to the scheme. This implies that 48% of the funds are still left to be released before October 2019. 
Construction of Individual Household Latrines (IHHLs): For construction of IHHLs, funds are shared between the centre and states in the 60:40 ratio. Construction of IHHLs account for the largest share of total expenditure under the scheme (97%-98%). Although the number of toilets constructed each year has increased, the pace of annual growth of constructing these toilets has come down. In 2015-16, the number of toilets constructed was 156% higher than the previous year. This could be due to the fact that 2015-16 was the first full year of implementation of the scheme. The growth in construction of new toilets reduced to 74% in 2016-17, and further to 4% in 2017-18.
As of February 2018, 78.8% of households in India had a toilet. This implies that 15 crore toilets have been constructed so far. However, four crore more toilets need to be construced in the next 20 months for the scheme to achieve its target by 2019.
Open Defecation Free (ODF) villages: Under SBM-G, a village is ODF when: (i) there are no visible faeces in the village, and (ii) every household as well as public/community institution uses safe technology options for faecal disposal. After a village declares itself ODF, states are required to carry out verification of the ODF status of such a village. This includes access to a toilet facility and its usage, and safe disposal of faecal matter through septic tanks. So far, out of all villages in the country, 72% have been verified as ODF. This implies that 28% villages are left to be verified as ODF for the scheme to achieve its target by 2019.
Information, Education and Communication (IEC) activities: As per the SBM-G guidelines, 8% of funds earmarked for SBM-G in a year should be utilised for IEC activities. These activities primarily aim to mobilise behavioural change towards the use of toilets among people. However, allocation towards this component has remained in the 1%-4% range. In 2017-18, Rs 229 crore is expected to be spent, amounting to 2% of total expenditure.
What is the implementation status of the National Rural Drinking Water Programme?
The National Rural Drinking Water Programme (NRDWP) aims at assisting states in providing adequate and safe drinking water to the rural population in the country. In 2018-19, the scheme has been allocated Rs 7,000 crore, accounting for 31% of the Ministry’s finances.
Coverage under the scheme: As of August 2017, 96% of rural habitations have access to safe drinking water. In 2011, the Ministry came out with a strategic plan for the period 2011-22. The plan identified certain standards for coverage of habitations with water supply, including targets for per day supply of drinking water. As of February 2018, 74% habitations are fully covered (receiving 55 litres per capita per day), and 22% habitations are partially covered (receiving less than 55 litres per capita per day). The Ministry aims to cover 90% rural households with piped water supply and 80% rural households with tap connections by 2022. The Estimates Committee of Parliament (2015) observed that piped water supply was available to only 47% of rural habitations, out of which only 15% had household tap connections.
Contamination of drinking water: It has been noted that NRDWP is over-dependant on ground water. However, ground water is contaminated in over 20 states. For instance, high arsenic contamination has been found in 68 districts of 10 states. These states are Haryana, Punjab, Uttar Pradesh, Bihar, Jharkhand, Chhattisgarh, West Bengal, Assam, Manipur, and Karnataka.
Chemical contamination of ground water has also been reported due to deeper drilling for drinking water sources. It has been recommended that out of the total funds for NRDWP, allocation for water quality monitoring and surveillance should not be less than 5%. Presently, it is 3% of the total funds. It has also been suggested that water quality laboratories for water testing should be set up throughout the country.
