To satisfy the contracted 30 MGD Virginia Beach, Lake Gaston Water Supply Project water demands on the Moores Bridges Water Treatment Plant and provide a reliable and consistent plant effluent water quality which will meet current provisions of the Safe Drinking Water Act and Virginia Department of Health regulations, the City undertook an $82,000,000 capital improvement project to upgrade and expand to 108 MGD its Moores Bridges Water Treatment Plant. A critical element of this project was the design and installation of a comprehensive distributed control system (DCS)/supervisory control and data acquisition (SCADA) system. This system will monitor and control the facilities at the Moores bridges plant and all remote water system facilities. In addition, the DCS/SCADA system will accept signals from 126 remote wastewater collection pumping station and monitoring sites. The intital phase of the project included field investigations to ascertain the number and locations of facilities to be monitored and controlled, discussions with City personnel to determine needs and desires, and meeting with process and other engineering disciplines for monitoring and control requirements. A technical memorandum was then prepared which discussed the various sites including their locations, instruments at each site, condition of the instruments and control system recommendations. The next phase involved the preparation of design documents to implement the selected recommendations. This paper presents a discussion of the various options considered in the preparation of the documents.
