The project has been undertaken and funded as part of the UK Department of International Development (DFID)’s Knowledge and Research Programme. The initial concept for the research was developed by Black & Veatch Consulting Ltd in 2003 in line with the DFID agenda on poverty alleviation and within the context of the UN Millennium Development Goals. Water demand management has become an important element in integrated policies of water resources development and the purpose of the research has been to: develop water demand management strategies in areas where aquifers1 are being over-exploited, ensuring the long-term livelihoods of the vulnerable and poor are safeguarded; and to discuss and disseminate the findings with potential end users of the research (Donor agencies, Government and agencies involved in water management). Although the broad outlines of the strategies discussed in this report are widely applicable, the studies have been undertaken in developing countries with emphasis being given to pro-poor policies and poverty reduction. The research addresses the DFID Research Areas related to Millennium Development Goal No. 7, “Ensuring Environmental Sustainability”. It addresses elements of the corresponding DFID research areas of natural resource management; reducing pollution and environmental damage; access to safe water supply; and improving the quality of life for slum dwellers. During the studies a number of issues arose which have influenced the development of this document: It became clear that a water demand management strategy must be viewed as one component of a wider water resources strategy and although, in this document, the authors have concentrated on water demand management options, they have taken a broader view when discussing the development of a water strategy; Water demand management measures can be used to influence the distribution of water and, where equity and pro-poor policies are being introduced in areas of water shortage, there may be “losers” as well as “winners”. The political context becomes a central issue in their introduction; Water demand management measures will only be successful if they are acceptable to the policy makers and the consumers. In many developing countries, there is a hunger for and political will to change. In introducing demand management measures, however, a number of vested interests may have to be overcome. The existing drivers for change have to be understood and, if the measures are to be promoted successfully, they must 1 The studies have been widened where possible to make the findings applicable both to areas where aquifers are being over-exploited and to areas where surface water resources are restricted. 01 June 2006 1 DFID R8332 Water demand management in areas of groundwater over-exploitation WATER DEMAND MANAGEMENT - STRATEGY FORMULATION FINAL REPORT - February 2006 __________________________________________________________________________ have a sound basis where they confront established assumptions on water priorities. A number of studies have been undertaken in developing the material for this document, which describes an approach to Strategy Formulation for Water Demand Management. These included a Knowledge Review and Case Studies in Chennai, India and in Al Jafr, Jordan during 2004 followed by workshops and meetings with stakeholders in Chennai and Jordan in November 2004. A Case Study Report was submitted to DFID in January 2005. Additional studies were undertaken in Pondicherry, India and Andhra Pradesh in 2005 to test the approach proposed in this Strategy Document and a final workshop with stakeholders was held in New Delhi in November 2005. Black & Veatch Ltd has led the research, providing inputs on water resources, hydrogeology, economics, community participation, poverty and gender issues. The principal research collaborators have been: VRV Consultants (P) Ltd. and the Centre for Poverty Alleviation (CUPA) in India; and Jouzy & Partners and JOHUD, Queen Zein Al Sharaf Institute (ZENID) in Jordan This document “Water demand management – Strategy formulation”, the final report arising from the research project, comprises a Main Report plus three Annexes. The Main Report describes the background and overall approach to formulating a water demand management strategy. Annex A discusses poverty and vulnerability; Annex B describes the case studies undertaken in India and Jordan; and Annex C describes water demand management measures and water supply options.

Introduction The purpose of this report is to disseminate the findings of a project funded by the UK Government’s Department for International Development (DFID) under its Knowledge and Research Programme, Project R8332 - Water Demand Management in Areas of Groundwater Over-exploitation. The purpose of the research project was to develop water demand management strategies in areas where aquifers are being over-exploited, ensuring the long-term livelihoods of the vulnerable and poor are safeguarded. Many countries have reached a position where the quantity or quality of fresh water renewable resources will not meet the demand for the resource and is imposing a limit on economic development. Others are rapidly approaching a similar critical situation. These countries face a common problem - the implementation of existing policies

    Issues pertaining to Peninsular Rivers wing i. Interstate matters: (a) Mullaperiyar Dam Issue 1. On 29‐10‐1886, a lease indenture for 999 years was made between Maharaja of Travancore and Secretary of State for India for Periyar irrigation works. By another agreement in 1970, Tamil Nadu was permitted to generate power also. The Mullaperiyar Dam was constructed during 1887‐1895. Its full reservoir level is 152 ft and it provides water through a tunnel to Vaigai basin in Tamil Nadu for irrigation benefits in 68558 ha area. 2. In 1979, reports appeared in Kerala Press about damage to Periyar Dam. On 25th November, 1979 Chairman, CWC held meeting with the officers of Irrigation and Electricity, Deptt. of Kerala and PWD of Tamil Nadu and some emergency medium term measures and long‐term measures for strengthening of Periyar Dam were decided. A second meeting under the Chairmanship of Chairman, CWC was held on 29th April 1980 and it was opined that after the completion of emergency and medium term measures, the water level in the reservoir can be raised up to 145 ft. 3. The matter became sub‐judice with several petitions. On the directions of the Supreme Court in its order dated 28.4.2000, Minister (WR) convened the Inter‐State meeting on 19.5.2000 and as decided in the meeting, an Expert Committee under Member (D&R), CWC with representatives from both States was constituted in June 2000 to study the safety of the dam. The Committee in its report of March, 2001 opined that with the strengthening measures implemented, the water level can be raised from 136 ft.

  • Need to Ensure Adequate Availability of Water in Palar River in Tamil Nadu and Also Expedite Pennayar - Palar Link Canal Project
    an> Title: Need to ensure adequate availability of water in Palar River in Tamil Nadu and also expedite Pennayar - Palar Link Canal Project. SHRI B. SENGUTTUVAN (VELLORE): River Palar, an inter-State river, originating in Karnataka, runs to a distance of 53 kms in Karnataka, 30 kms in Andhra Pradesh and 222 kms in Tamil Nadu. The river is covered under Schedule-A of the Madras-Mysore Agreement. As per Clause II of Agreement upstream State cannot construct any dam or reservoir without consent of the downstream State. During the monsoons, where adequate rainfall is received, the waters of the river replenish more than one thousand tanks, ponds and lakes on either side of its banks, which are the sources of water of drinking and irrigation in Vellore and Kancheepuram Districts. The Palar ayacut supports cultivation of roughly 4.2 lakh acres of lands. However, due to the construction of Check-dams across the river by neighbouring States of Karnataka and Andhra Pradesh, the water flow in the river has completely ceased leaving the land patched, dry and drought-stricken. To compound the problems, the Andhra Pradesh Government is raising the height of check dam in Perumpallam village on the very border of Tamil Nadu State to a height of 12 feet and more with a view to converting it into a reservoir. This would seriously impede water flow in the Palar and deprive Tamil Nadu of the much needed Palar water. In order to protect the ayacutdars, the inter-state Palar River has to be nationalised removing all dams and barriers constructed across it and the 52 km long Pennayar-Palar Link Canal Project has to be implemented expeditiously.

Although the monsoons effect most part of India, the amount of rainfall varies from heavy to scanty on different parts. There is great regional and temporal variation in the distribution of rainfall. Over 80% of the annual rainfall is received in the four rainy months of June to September. The average annual rainfall is about 125 cm, but it has great spatial variations. This lead to excess rainfall in one region which results the flood and water shortage in other region which leads to the drought in other region. The interlinking project are envisaged with aim to transfer the water from the water surplus region the water deficit region.
