Moulton Niguel Water District (MNWD) in southern California is implementing an intranet- based information portal to and management toolkit for a variety of critical asset and operating data for its recycled water system. Included are system and facility descriptions; system management and facility operating procedures; databases; administrative, institutional and regulatory requirements and records; facility construction and other system drawings; and system models and other analytical tools. The integrated databases, which include maintenance management, supervisory control and data acquisition (SCADA) system and customer data, are accessed via convenient menu-driven, schematic and geographical user interfaces. The management tools include integrated access to a full-featured hydraulic network model and several custom spreadsheet-based models. The information portal includes built-in Internet links to equipment supplier, utility and other provider websites. The aggregate of these data and tools is called the Management System Standard Operating Procedures (MSSOP), which functions on a typical networked desktop computer as a single application running in a conventional web browser. Final refinements and additions to the recycled water MSSOP, including features of a geographic information system (GIS), are being implemented. Includes table, figures.
