Job Title
Hydraulic Modeler (Water / Wastewater Engineer)
Job Summary
The Hydraulic Modeler is responsible for developing, calibrating, and analyzing hydraulic models for water supply, wastewater, and stormwater systems. The role supports planning, design, optimization, and troubleshooting of hydraulic networks using specialized modeling software to ensure efficient, reliable, and compliant infrastructure performance.
Key Responsibilities
- Develop and maintain hydraulic models for water distribution, wastewater collection, and stormwater drainage systems.
- Collect, review, and validate field data including flow, pressure, pipe networks, and system performance.
- Perform simulations to analyze system behavior under various operating conditions and demand scenarios.
- Calibrate hydraulic models using real-world data to ensure accuracy and reliability.
- Identify system deficiencies, bottlenecks, and risks, and recommend improvement solutions.
- Support design of new infrastructure and rehabilitation of existing networks.
- Evaluate impacts of new developments on existing hydraulic systems.
- Prepare technical reports, maps, drawings, and presentation materials for stakeholders.
- Coordinate with civil, environmental, and municipal engineers, as well as utility authorities.
- Support master planning studies and feasibility assessments.
- Use GIS data and mapping tools to integrate spatial information into hydraulic models.
- Ensure compliance with applicable engineering standards and regulations.
- Assist in cost estimation and design optimization based on model outputs.
Required Qualifications
- Bachelor’s degree in Civil Engineering, Environmental Engineering, Water Resources Engineering, or related field.
- 3–10+ years of experience in hydraulic modeling or water/wastewater engineering.
- Experience with municipal or infrastructure water system projects.
Required Skills
