We have extensive experience in the programming, evaluation, planning, design, and construction of stormwater and sanitary sewer projects. Often the complexity of a project requires expertise in computer modeling, water quality sampling and analysis, and tunneling methods. Further, many of our designs are completed on expedited schedules in order to meet funding or other constraints. These projects are routinely begun by conducting hydraulic analyses, stormwater studies, sewer separation studies, retention and detention calculations and studies. Our staff then  uses the findings of these studies to prepare designs for facilities such as storm sewers; ditches and culverts; stormwater drainage for roadways and parking lots; and retention and detention basins. Our designs have included large diameter storm sewers; utility relocations; utility master plans (including storm and sanitary sewer systems); and storm and sanitary sewer separations (including large diameter).
