PAGE 1 OF 12
David Cameron-Ellis’ 29 years of post-graduate experience has focused primarily on the design and rehabilitation of dams. His experience extends from basic planning through to construction implementation. He has worked on numerous dam types, including earthfill, rockfill, RCC, Hardfill, RMC and conventional concrete dams.
David has been involved in several hydro-electric projects with contributions ranging from design and management of small schemes to team member on larger ones.
In addition, he has extensive experience in project management, the design of civil structures, such as reservoirs and bridges, and the design and implementation of civil engineering services projects, such as water and wastewater systems. His experience in water retaining structures includes his early construction monitoring experience as resident engineer on the Grand Central Reservoir and Pressure Tower and has progressed though the rehabilitation of a number of reservoirs in Malawi and the design of numerous water treatment works and dam related structures.
David is currently a director in the Dams and Hydro division at ARQ. In addition to being a Management Committee member and Treasurer of South African Committee on Large Dams; he also serves as South Africa’s representative on the International Commission on Large Dams’ Cemented Materials Committee.
