Owner/President

Karen Ridgway is a nationally recognized expert in the field of computational hydraulic/hydrologic modeling.  She has spent her 30 year career in this field, has utilized a full range of established software programs on numerous projects large and small, and has developed her own programs for use on projects when necessary.

Ms. Ridgway is a Civil Engineer who is an expert in hydraulics and hydrology as applied to water, wastewater, streams, watersheds and drainage systems.  She has extensive experience in the hydraulic design of major pumping, drainage, sewerage, water and wastewater treatment and water distribution systems, including the design of a small dam, major sewage and storm water pumping stations, water and wastewater treatment plants, combined sewer overflow basins and tunnels, large capacity drop structures, open channels, pipelines, manifolds, and metering facilities. Ms. Ridgway has worked on numerous projects requiring permits and compliance with combined sewer overflow, sanitary sewer overflow, and other surface water and ground water discharge regulations. 

Ms. Ridgway has also developed several original computer models for civil engineering applications including a program for the analysis of open and closed conduit steady-state and unsteady-state flow conditions in pipe networks named the Transient Analysis Program (TAP).  TAP has been used to evaluate real-time in-system storage dam operations in combined sewers, analyze surges in CSO tunnels, and perform steady-state backwater profile calculations.

Ms. Ridgway also has extensive experience in the hydraulic design of major pumping, drainage, sewerage, and water distribution systems, including the design of a small dam, major sewerage and stormwater pumping stations, large capacity drop structures, open channels, pipelines, manifolds, CSO basins and tunnels, and metering facilities - as the designer and as a Value Engineering team member.
