Basic Metal and Engineering Industries Agency (BMEIA) is located in Addis Ababa, Ethiopia. The agency aspires to be a center of excellence for the Basic Metals and Engineering Industries sub-sector with respect to research and development activities. BMEIA has developed a range of products including machinery, plastic moulds, and press tools as customized systems or research activities. In addition, the agency develops suitable technologies for rural communities, in particular, products related to water supply systems. One such product is the hydraulic ram (Hydram) pump. The Hydram is used to supply water for rural communities, mainly for livestock and irrigation purposes. After discovering and refurbishing a station of Hydram pumps in Ziway, BMEIA proposed to supply water for a small village (population of about 500 people) from a stream of water using a Hydram pump. The Hydram pump components must be designed to specifications generated from from the results of a site survey and an environmental assessment.
This case helps to apply Bernoulli’s and other fluid mechanics equations in system development. It planned to teach engineering design process beginning with problem identification, conceptual design, preliminary design, and detail design including cost estimation and selecting manufacturing methods.

The University of Waterloo acknowledges that much of our work takes place on the traditional territory of the Neutral, Anishinaabeg and Haudenosaunee peoples. Our main campus is situated on the Haldimand Tract, the land granted to the Six Nations that includes six miles on each side of the Grand River. Our active work toward reconciliation takes place across our campuses through research, learning, teaching, and community building, and is co-ordinated within the Office of Indigenous Relations.
