The Federal Democratic Republic of Ethiopia received financing from the International Development Association (IDA) for the im-plementation of Second Urban Water Supply and Sanitation Project (SUWSSP). The Ministry of Water and Energy applied a por-tion of the proceeds of the fund to SNNP Regional State Water, Mines and Energy Development Bureau. The SNNP Region is in the southern part of Ethiopia, its area covers 112,343 km2 and its population is over 15 million. The capital city is Hawassa. The Project focused on the cities of Hawassa, Wolaita Sodo and Arba Minch and included two main assignments, each with its own specific objectives and scope of services:
- Develop a Non-Revenue Water (NRW) Reduction Strategic Plan.
- Develop a Business Plan.
As the two assignments feed into each other, Z&A executed the two assignments concurrently for each of the three Water Enterprises.
Main water supply service and operation data for the three cities are given in the below table.
