Technical Assessment Survey of Water Supply Schemes is an important component of Provision of Safe Drinking Water Project. The main objective of the Technical Assessment Survey is to assess the status of all existing water supply schemes in Pakistan. The assessment will: identify problems existed in the water supply schemes, analyze reasons of the inability of the schemes to deliver safe drinking water to the communities, types of pollution found in surface and groundwater which are being used as sources of domestic water supply in various areas of the country, and recommend prevention and remedial measures to ensure the delivery of safe drinking water to the communities. The Technical Assessment Survey Report of Water Supply Schemes of Punjab, produced by PCRWR Technical Survey Teams, provides us with an insight on the social, technical, managerial and water quality problems faced by water supply schemes located in 21 districts of northern and central Punjab. The report also provides practical solutions to the mangers of water supply schemes, policy makers and researchers to understand the deep rooted problems and to determine priority areas for improvement of access to safe drinking water for the people in the Province.
