SAERT
Sustainable Agriculture and Environmental Rehabilitation in Tigray (SAERT) was a parastatal organisation in the Tigray Region of Ethiopia. It was established in 1995 for "policymaking, design and construction of dams and canals, and the maintenance of dams and water distribution systems". SAERT was funded jointly by the United Nations Development Programme, United Nations Economic Commission for Africa and Food and Agriculture Organization, Food and Agriculture Organization of the United Nations, with the Regional Government of Tigray sharing project financing in kind. It started as a project but it was later established as a commission (co-SAERT). The first project manager was Leul Kahsay who later became deputy commissioner. Abay Tsehaye was the first commissioner appointed by the Regional government. Initially, SAERT planned on small-scale irrigation projects in the Region through constructions of 500 earthen micro-dams in ten years. In the first year construction work started a ...

Gereb Bi'ati
Gereb Bi’ati is a reservoir located near Mekelle in the Tigray Region in Ethiopia. The earthen dam that holds the reservoir was built in 2000 by SAERT. Dam characteristics * Dam height: 17 metres * Dam crest length: 578 metres * Spillway width: 40 metres Capacity * Original capacity: 1005841 m³ * Dead storage: 232728 m³ * Reservoir area: 17 ha * Designed irrigated area: 88 ha Environment The catchment of the reservoir is 9.71 km² large, with a perimeter of 14.24 km and a length of 4960 metres. Due to the possibility to by-pass sediment-laden water, the reservoir suffers from less rapid siltation. The lithology of the catchment is Agula Shale and Mekelle Dolerite. Part of the water that could be used for irrigation is lost through seepage; the positive side-effect is that this contributes to groundwater recharge.
