Professional Summary

Eng. Wondwosen Tesfaye Denbel is an experienced Environmental Engineer and WASH Infrastructure Specialist whose career combines engineering design, construction supervision, water resources research, environmental health, regulatory compliance and public infrastructure quality assurance. With more than fifteen years of cumulative professional and academic experience, he has progressed from university teaching and research to hands-on sanitary engineering, water and wastewater infrastructure supervision, watershed research and national-level sanitary design regulation. He currently serves as a Projects Sanitary Design Regulatory Expert at the Ethiopian Construction Authority, where he reviews major building and WASH design submissions, conducts compliance inspections, evaluates environmental considerations and works with consultants to improve the safety, sustainability and technical integrity of water supply, sanitation, wastewater, stormwater and plumbing systems. His professional strength lies in connecting engineering design with public health, environmental sustainability, regulatory standards and practical field implementation. He also brings strong capability in GIS, remote sensing, SWAT, WaterGEMS, SewerGEMS, AutoCAD Civil 3D and BIM-based engineering workflows, giving him a valuable multidisciplinary perspective on resilient water and environmental infrastructure.

Key Expertise

Major Projects and Contributions

• National Sanitary Design Regulation and WASH Infrastructure Compliance
  Serves as Projects Sanitary Design Regulatory Expert at the Ethiopian Construction Authority, reviewing major public and private sanitary engineering and WASH design submissions against applicable codes and standards. His work includes technical review of water supply, wastewater drainage, stormwater and plumbing systems, weekly site compliance inspections, identification and correction of installation defects, coordination with consultants and evaluation of environmental considerations affecting infrastructure safety, public health and sustainability.
• G+18 Apartment Water Supply, Wastewater and Stormwater Design
  Designed comprehensive water supply, wastewater drainage and stormwater management systems for a G+18 apartment development. Prepared coordinated engineering layouts using AutoCAD with emphasis on efficient hydraulic flow, safe sanitation, effective drainage and compliance with building and infrastructure standards.
• Water Resources and Watershed Management Research
  Worked as a Water Resources and Watershed Management Junior Researcher with the Ministry of Water, Irrigation and Electricity. Identified water-scarcity challenges in drought-prone regions, contributed technical evidence for irrigation and water management planning, conducted watershed mapping using GIS and remote sensing, analyzed research data using SPSS, collected water-quality samples, evaluated hydrologic information and prepared technical reports for sector stakeholders.
• Emergency Environmental Health and WASH Needs Assessment
  Participated in rapid environmental health and WASH needs assessments in emergency settings to support the planning and implementation of practical and sustainable water, sanitation and hygiene response strategies. The work connected field assessment, environmental health risk identification, infrastructure needs and community-focused WASH planning.
• Water Treatment, Wastewater Treatment and Stormwater Engineering
  Worked on sanitary engineering assignments involving assessment, design and supervision of water treatment, wastewater treatment and stormwater management systems. Responsibilities included technical assessment of existing wastewater facilities, identifying opportunities for improved efficiency and lower costs, designing drainage and runoff-control systems, supporting flood reduction and improving water-quality protection.
• Water-Related Infrastructure Design and Construction Supervision
  Planned, designed and supervised water-related development works, including preparation of engineering designs, bills of quantities, cost estimates and technical documentation. Supported infrastructure implementation through site supervision, quality-control monitoring and evaluation of wastewater disposal and treatment solutions to achieve safe, cost-effective and technically compliant delivery.
• Sanitary Engineering and Waste-System Construction Management
  Served as a Site Sanitary Engineer responsible for planning, organizing, supervising and evaluating sanitation works and waste-system construction. Coordinated with consultants and regulatory stakeholders, assessed environmental contaminant and public-health risks, prepared cost estimates and supported financial implementation planning for WASH-related activities.
• Environmental Engineering Education and Research – Haramaya University
  Served as Assistant Lecturer at Haramaya University, contributing to engineering education, laboratory and practical instruction, student learning, research data collection and analysis, university social activities and academic and administrative responsibilities. This early academic experience established a strong foundation for his later engineering, research and regulatory career.
• Advanced Water Engineering and Digital Modelling Capacity Development
  Completed extensive professional development in modern water and environmental engineering tools and approaches, including SWAT modelling, GIS and remote sensing, AutoCAD Civil 3D canal design, WaterGEMS, SewerGEMS, BIM MEP Plumbing, BIM Project Management, SPSS, research methodology, WASH systems strengthening, project management, Integrated Water Resources Management for climate resilience and drinking water quality testing.
