Wells and Step-wells

“PAWAN GURU, pani pita, mata dharti mahat” (air is teacher, water is father and earth our mother) -  thus goes the closing line of the Japji Sahib given by the founder of Sikhism, Guru Nanak Dev. It holds special significance for Amritsar, the holy city, which boasts of the Harmandar Sahib (also known as the Golden Temple).

Both rural and urban India are faced with water problems. People do not have access to good quality, safe drinking water. The source for most drinking water is either rivers or underground aquifers (wells). Since water can dissolve just about anything that it comes into contact with long enough, often the groundwater we get isn’t pure.

For the last 50 years, the Bhilai Steel Plant, which is India's largest integrated steel plant has got its supply of iron ore from Dalli Rajhara's mines. Dalli Rajhara, a municipality which is also an industrial city is located 90km south of Durg in Chhattisgarh. It is a part of the Rajhara group of mines. Iron ore mined in this area are of two types - hematite and magnetite.

Green pastures and meadows, tall trees, lakes, wells and the river…those are my memories of Delhi. It wasn’t too long ago that one woke up early to the sounds of lawns being watered, children running off to school and people walking in the parks. A flurry of activity but quite different from what it is today.

Kerala is a rain blessed state in the country. It has highest  number of wells, when compared with other states. However due to its slanting topography there is significant decline in the ground water levels leading to severe water scarcity during summer months in most districts of the state. Further over extraction and dependence of groundwater for domestic use from the dug wells especially in rural pockets has resulted in several groundwater problems. In this backdrop the paper in  The Ecosan- An International Quarterly Journal of Environmental Science, sheds light on groundwater quality issues in two panchayats of Kerala.

Land use changes  hydrologic system and have potentially large impacts on water resources. An assessment in an area with seasonally limited water availability and which is subject to rapid socio- economic development and population growth will provide an exemplary view on the local impacts of major recent developments in India. In this backdrop this paper analyzes past land use changes between 1989 and 2009 and their impacts on the water balance in the Mula and Mutha Rivers catchment upstream of Pune. The aim of the paper is:

• assess the land use changes between 1989/1990 and 2009/2010
• analyze the impacts of these changes on the long-term water balance components in the Mula and Mutha Rivers catchment upstream of the city of Pune.

Given the many problems associated with flush toilets and the sewerage system, pit toilets offer a viable solution in India. However, the use of soakpits raises the question of groundwater contamination. This paper assesses the impact of pit toilet leachate on groundwater quality in Mulbagal town (pop ~ 60,000) in Karnataka relies on pit toilets, and uses groundwater for drinking.

IWMI-Tata water policy research programme is a collaborative initiative between the International Water Management Institute (IWMI) and the Sir Ratan Tata Trust (SRTT). 

 At the same time we also need to keep in mind the judicious use of natural  resources, especially in rain-fed areas. Integrating sustainability and demand is one of the greatest challenges faced by communities and nations today.
