In all these states, hand pumps drive most of the progress whereas piped water supply accounts for a mere Yet, several other states like Andhra Pradesh, Karnataka and Tamil Nadu regard hand pumps as an obsolete way to provide drinking water supplies. In these three states only Quality of water is dependent on the source of supply. We have made an attempt to explore the determinants of water quality.

Water quality has been examined on the basis of contamination by fluoride, arsenic, iron, salinity, and nitrate using data from the Ministry of Drinking Water and Sanitation 5. A regression analysis has been undertaken to explain the variation in the number of people affected by contamination across states.

The two regression models are presented below with a representing regression coefficients :. The regression results suggest that piped water supply delivered using either ground or surface water reduces contamination of water. Contamination increases with traditional sources, open wells, hand pumps, and other tubewells.

This suggests that communities relying on hand pumps and tubewells for their water supply are more likely to be exposed to contaminated water supply than communities served by piped water supply. A comparison of the two Indian States Jharkhand and Karnataka demonstrates the role of technology in ensuring improved water safety and security. The type of major sources of water supply in Karnataka is markedly different from Jharkhand. In the rural areas of Jharkhand tubewells and borewell are important sources of water supply whilst in Karnataka piped water supply is the main water supply source.

Karnataka appears to be slightly better compared to Jharkhand with respect to sufficiency of water supply in spite of the fact that a large part of the state is in a drought prone area. Distance to major sources of water supply is much higher in Jharkhand as compared to Karnataka 6. The type of access and distance to water supply sources has implications for waiting time and time taken in a day to reach the source. Both waiting time and time taken to reach the source are much less in Karnataka than in Jharkhand, increasing the time available for other activities, such as income generation and education, in Karnataka.

Delivery of drinking water supply in rural India has taken different shapes in different States, primarily due to the choice of technology by the respective State governments. While some have emphasized hand pumps, others have taken measures to set-up piped water supplies.

Under the common national program for ensuring safe drinking water in the vicinity of households, providing services by piped water supply is a better option than hand pumps. This is because piped water supply can more effectively improve drinking water security when coupled with safety norms to reduce water contamination, than other technologies, like hand pumps.

Although reported coverage is much higher in Jharkhand, access at the household level is better in Karnataka and the distance to sources and waiting time to collect water are less. This means that in spite of high coverage in Jharkhand, access to improved water sources could be low. Overall, as technology is the critical enabler for ensuring safe and adequate drinking water to rural households, investments made in piped water connections or access to piped water should set national benchmarks when estimating coverage of improved water supply. These revised estimates may guide the post agenda more effectively moving forward.

Uday Shankar Prasad is associated with water, sanitation and hygiene WASH sector for the past ten years and contributing to the monitoring of national programmes on drinking water and sanitation in India. Apart from his interest in design and development of management information system MIS , he has been conducting studies on sustainability of WASH interventions. Prasad is currently employed with WaterAid, an international charity, and served as a consultant to the government organisations.

This provides an interesting and useful comparative analysis of major sources improved technology of water supply and accessibility and ease of water collection from these sources in high and low covered by water supply states in India. Background and trends in rural drinking water supplies. The Census of India presents a marked shift towards improved water sources and also opens-up new questions for policy planners.

The evidence clearly demonstrates the increasing prevalence of improved technology between and Under the national flagship National Rural Drinking Water Programme NRDWP , a majority of habitations fulfill the criterion of access to adequate quantity and quality of safe drinking water.

The two technological options, hand pumps and piped water supply, have gained acceptance by some States as effective means of providing drinking water supplies.

However, there have been multiple approaches to promote safe drinking water schemes. For example, Madhya Pradesh, Jharkhand and Chhattisgarh have reported In all these states, hand pumps drive most of the progress whereas piped water supply accounts for a mere Yet, several other states like Andhra Pradesh, Karnataka and Tamil Nadu regard hand pumps as an obsolete way to provide drinking water supplies.
