The City of Portland, Oregon, recently placed into service a 100 mgd pumping station as a major milestone in developing a backup and emergency groundwater supply. The facility is also designed to serve as a five megawatt hydropower generating station. Both the pumping station and the groundwater supply wells are controlled through a computerized control system. A critical element of the facility design was the control of hydraulic transients due to the sensitivity of the existing supply pipelines. Computer modeling performed as a part of design has been confirmed by the results of power failure and load rejection commissioning tests performed to date.
