Perform design and analysis tasks for water and wastewater conveyance assignments, including hydraulic capacity evaluation, alternatives analysis, rehabilitation versus replacement strategy, pipeline and force main design, pump and lift station design, diversion and flow control structures, and trenchless and tunnel engineering support.
Building and running hydraulic models and preparing engineering calculations, including capacity evaluations, alternatives analyses, and hydraulic profiles, and document assumptions and results clearly enough for independent review.
Producing plans, details, specifications, and technical memoranda in AutoCAD/Civil 3D, GIS, and Microsoft Office, and incorporating review comments from senior staff, clients, and reviewing agencies.
Supporting condition assessment, inflow and infiltration, and capacity assurance work, including data compilation, field data reduction, and GIS analysis.
