There are oversized undersized pipes high pressure in the existing system caused by customers at too low demand have been identified and a solution is established using pressure reducing valve. The result showed that the water supply scope was very low which covers only 56.3%, besides water demand and supply of Adwa town were not balanced. The residents of a town used daily water 13.76 litter for different domestic activities with the billed water amount is 69.9%of production and around 30.10%water is considered to be non-revenue (NRW) and the apparent losses and real losses of the town respectively. The other observed problem in Adwa town is recurrent pipe leakage the water distribution network during which the town water utilities do not have an instantaneous rejoinder for maintenance. Therefore, by considering the large water losses of the Adwa town water distribution system, a plan for the rehabilitation and modernization of UWDS must be established, starting with the GI pipes where the largest water losses are recorded.
