INTRODUCTION 1.1. Background The Govt. of Kerala (GoK), encouraged by the people's demand for better quality of life through improved access to safe water supply and sanitation services, and their willingness to participate in all stages of development from planning to implementation including total responsibility for operation and maintenance (O & M) of the systems, proposes to launch, with World Bank assistance, a pilot water supply and sanitation project in four districts of the state, with scope for replication of the model in other parts of the state. The GoK, which has initiated the decentralised planning programme since 1997, will implement the project through its recently established Rural Water and Sanitation Agency (RWSA). The project is in the preparation stage and is aimed at improving the quality of rural water supply and environmental sanitation service delivery to achieve sustainability of investment and generate health and income benefits. This will be realised through (a) phased implementation of appropriate policy and institutional reforms and (b) delivery of demand responsive and sustainable water and sanitation services to the beneficiary communities in the pilot districts. The key components of the project include construction of new / augmentation/ rehabilitation of drinking water schemes, drainage schemes, household latrines, solid waste disposal systems, and environmentalmanagement and watershed development schemes. The health, hygiene and sanitation component of the project includes health and hygiene education programs for safe handling of drinking water, disposal of waste water (sullage), personal hygiene, household hygiene and community environmental sanitation.
