Key Expertise

Major Projects and Contributions

• District Metered Area Design
  Designed District Metered Area zones and monitoring points to improve control of water distribution networks, pressure management, leakage monitoring, and water-loss tracking at zone level.
• Water Supply Demand Modelling Using WEAP
  Developed WEAP models to assess current and future water demand and supply scenarios, analyze population growth and consumption patterns, identify supply gaps, and support long-term water planning decisions.
• Non-Revenue Water Reduction Strategy
  Developed an engineering framework for reducing Non-Revenue Water by addressing leakage, metering errors, apparent losses, and unauthorized use, with a reduction plan and performance indicators to improve utility efficiency.
• Hydraulic Modelling of Water Distribution Networks
  Built, analyzed, and calibrated hydraulic network models using WaterGEMS. Simulated pressure and flow under different demand scenarios, identified low-pressure zones, and supported network improvement planning.
• Irrigation Infrastructure Development
  Supervised construction of irrigation canals and distribution systems in Ambasel Woreda, prepared engineering drawings with AutoCAD and Civil 3D, conducted calculations and field inspections, and supported groundwater investigations.
• Urban Drainage and Sanitation Design
  Prepared drainage and sanitation solutions for urban areas and integrated flood-management considerations into infrastructure planning to reduce flood risk and improve urban sanitation.
