Short Description of the water distribution System The town is divided in to 4 pressure zones with different elevation range. The town has two types’ sources 1. One Spring about 95l/s discharge 2. Three Boreholes about 75l/s discharge The volume of daily water supply from these sources is estimated as 9,875m 3 /day. The source has a capacity to fulfill the demand of the town which is nearly 11,500m3/day. However, the current challenges are related to quality deterioration/pollution and Topography of the Town.ATWSSE has a total distribution pipe line length of 115Km and about 17Km Transmission line with pipe sizes ranging from DN1/2 inch to DN16 inch.
