Lifting and Extraction

 It is well known fact that water well hydraulics is derived from the petroleum industry, therefore borrowed the concept of synonymy between pumping and injection. Two reasons which favoured the presumption are 1. Solutions for crude oil injection were never so significant as compared to pumping in the petroleum industry, and 2.

This paper published by Megh Pyne Abhiyan argues that  dug wells slowly started losing their significance following the invention and large scale marketing of hand pumps,.

The Odisha Groundwater (Regulation, Development and Management) Bill, 2011 has been placed before the Odisha Legislative Assembly in this session. Odisha Water Forum has gone through the contents of this bill. While Odisha Water Forum appreciates the initiative of the Government of Odisha to regulate development and management of groundwater, it is concerned about the fact that this bill does not address the fundamental concerns regarding groundwater management.

It investigates the difficulties they face and emphasizes the need for better integration of groundwater in the planning and management of urban water resources.

With 49 per cent of the total irrigation from groundwater, the state of Andhra Pradesh accounts for 5.3 per cent of the net groundwater irrigated area in the country.

It covers varying groundwater scenarios in the country including the highly developed metros, the hilly region, the coastal cities, the cities tapping unconsolidated and hard rock aquifers. The report briefly describes the administrative set up, status of water supply and demand, groundwater scenario, feasibility of rainwater harvesting and groundwater development strategy.

It is an updated version of an earlier report on “Groundwater in urban environment in India” (2000). Since then, groundwater regime, urban demography and water demand have changed enormously. This report will form a scientific base for an in-depth understanding of urban groundwater system including aquifer geometry, water level behavior and groundwater quality. The possibility of artificial recharge to rejuvenate the urban aquifers has also been discussed.

 A large number of farmers and well operators were interviewed in the process. Data was also collected from the power utility that supplies power to this region. Along with this the climatic peculiarities of the region, farmers and well users perceptions on ground water management and use were also collected.

The global groundwater crisis centers on withdrawals notably exceeding short term renewable storage. The current global groundwater crisis reflects the fact that over the past century, groundwater withdrawal has grown to exceed natural renewable groundwater storage. The single most important cause is the deep well turbine pump. Groundwater depletion is very high in both the United States and India.
