This $290 million project created a new, sophisticated instrumentation and control system to provide real-time information about system-wide freshwater and wastewater flow levels, pump conditions and overflow status. The project included control and monitoring of 15,000 instrumentation points at 16 treated water pump stations, 24 booster stations, 36 wastewater collection stations, three detention basins, 60 outfall structures, 24 wastewater pumping stations, 162 remote monitoring sites, and the primary wastewater treatment plant.

Among its many responsibilities, Walbridge oversaw the excavation and installation of 12,000 lineal feet of reinforced concrete duct bank for a data communications highway, construction of six area control rooms, including the central plant control center, and installation of all conduit, wiring, instruments, control panels, remote operator stations, and remote terminal units for all 15,000 instrumentation points in all areas of the project.
