The following tools and resources have been developed to help water suppliers fulfill their responsibilities under the Drinking Water Protection Act and Drinking Water Protection Regulation. Professionals who will be conducting assessments, drinking water officers and water suppliers are the intended audiences for the Comprehensive Drinking Water Source-to-Tap Assessment Guideline also referred to as the CS2TA. The guideline provides a structured and consistent approach to evaluating risks to drinking water and satisfying the assessment requirement under Part 3 of the Drinking Water Protection Act. The Comprehensive Drinking Water Source-to-Tap Assessment Guideline is intended to help water suppliers develop a better understanding of the risks to drinking water safety and availability. It also can help suppliers operate more effectively in working to ensure the best possible water quality and assured quantity. The guideline can be applied under orders by a drinking water officer, or as a voluntary measure — undertaken by water suppliers wanting to understand risks to drinking water safety in their systems. If significant risks to a water system are identified through the Drinking Water Source-to-Tap Screening Tool or by some other means, a drinking water officer can order an assessment of the water system.

Urban water supply involves a number of components: the water source, treatment plant, service reservoirs and the distribution system. Water utilities are responsible for the operation and maintenance of water treatment plants and distribution networks, crucial for ensuring reliability and quality of supply. This study session begins by considering the organisational structure of a typical water utility in Ethiopia, and then concentrates on how adequate operation and maintenance of the water treatment and supply system can be undertaken through proper planning and implementation. You will also consider measures that may be put in place to cope with natural disasters such as floods. Water utilities are part of the organisational structure for water supply in towns and cities. In Ethiopia each woreda has a Council, and each town in the woreda has its own Town Council.
