Water Treatment Control System Design & Upgrade


Lake Oswego Tigard Water Partnership

Portland Engineering provided control system design engineering services for the $250 million Lake Oswego Tigard Water Partnership Water Treatment Plant expansion. This project is doubled the capacity of an existing water treatment plant through a multi-year phased construction plan; keeping the plant fully operational throughout the project. In addition to a complete rebuilding of the treatment plant the project also included a new intake structure, a new storage reservoir, a new pump station, and pipelines between locations. PEI is providing control system designs for all locations which included telemetry systems, communication networks, a plant-wide fiber-optic network, security/video systems, access controls and other ancillary systems as well as the PLC and HMI controls.
