The Third Water Supply and Sanitation for Low Income communities Project for Indonesia aims to increase the number of low-income rural and peri-urban populations accessing improved water and sanitation facilities and practicing improved hygiene behaviors. The project consists of the following components: Component 1: will support community driven development (CDD) planning and management of water, sanitation and hygiene improvement programs, build stakeholder commitment and expand the capacity of central, provincial and district government agencies. Component 2: will ensure that targeted community households gain access to improved sanitation facilities of their choice, are using improved water supply and sanitation infrastructure effectively and are progressively adopting key hygiene practices. Component 3: will provide participating communities with a menu of technical options for rural water supply and public sanitation infrastructure. Component 4: will provide incentives under two grant windows; the executing agency will finance grants to Districts. Component 5: will provide technical implementation support for components 1, 2, 3, and 4 and project management services to the implementing agencies.
