A custom Web-based Geographic Information System (WebGIS) allows for the integration of the maintenance management system (MMS), engineering drawings and geographical information system (GIS) at the Vallejo Sanitation and Flood Control District. WebGIS allows all staff (including O&M, engineering, and management) to access District databases and maps of its sanitary sewer system using a web browser (Figure 1). Ultimately, the WebGIS may be available to the general public via the Internet and through s kiosk located at the District's headquarters. In addition, the architecture of the WebGIS has the flexibility to integrate with other databases and maps layers used by the District and the City such as billing databases and potable water and storm drain system maps.

WebGIS developers collaborated with the District to understand business processes before development started (Figure 2). By integrating existing processes, the custom WebGIS compliment business practices without creating new work. The MMS is still run by the O&M staff, and the engineering department maintains records of improvements to the system. Now, however, the O&M and engineering staffs are working from a shared source of information that allows each of them to perform their functions more efficiently.

WebGIS integration positions the District well for early compliance with portions of the proposed Capacity Management, Operations and Maintenance (CMOM) regulations. The system provides maps and asset/condition assessment data required by CMOM. GIS maps and databases might also be integrated with hydraulic model of the District's system. Engineering staff can visually identify areas subject to Sanitary Sewer Overflows (SSOs), frequent corrective maintenance, and odor complaints. Capital planning can then be targeted to maximize results.
