NRCE was contracted by the Government of Eritrea (GoE) to design a dam, pumping plant, and pipeline to augment the municipal water supply in the city of Asmara.  The designed facilities comprised a 63-meter high dam and a pumping plant and pipeline to deliver approximately 7 million cubic meters of water per year.  As prime contractor, NRCE directed some of the efforts to Woodward-Clyde Consultants and Black & Veatch.  NRCE was responsible for topographic mapping, hydrological characterization, water quality appraisal, surveying, geotechnical support, and design estimate and construction document preparation. 
"NRCE performed critical preliminary design tasks.  Hydrologic modeling of the Toker Basin and sediment sampling program were performed during the rainy season of 1995.  Sediment yield and distribution in the reservoir was estimated.  Water quality modeling of the proposed reservoir has been completed.  Reservoir sizing analyses were performed to determine the dam height and incremental cost of delivered water.  All of these analyses facilitated the design of the structures.

NRCE also assisted the GoE by preparing construction bid documents, coordinating the international competitive bidding (ICB) process, and securing funding from international funding agencies.  NRCE was responsible for coordinating between the GoE and the International Contractor on this project.  NRCE also provided support to the GoE in meeting the requirements of the funding agency negotiating the loan agreements."
