Abstract
One of the major issues confronted by the agencies formulating polices for water supply projects in developing countries is how to achieve efficiency, equity and sustainability. Achieving these objectives warrants an understanding of the determinants of household behaviour towards various components of the water supply projects, such as improved water supply services. Since these determinants are site-specific in nature, it is imperative that the water supply policies identify and accommodate these factors appropriately. This paper discusses the results of a case study that looked into identification of such determinants of household decisions regarding the improved water supply services in a suburban town of Tamil Nadu State, India.
