City of San Marcos Water Reuse System Asset Management Plan 3 San Marcos System Inventory Developing an inventory of individual assets that make up the San Marcos water reuse system is the first key step in any asset management program. Detailed asset inventories were developed for the San Marcos reuse system including reuse pump station, pipelines and associated valves, flow meters, and control systems. The inventories were developed using existing data and information contained in San Marcos' geographical information system (GIS), Maximo CMMS system, record construction drawings, staff interviews, and field surveys. Available data that helped characterize the asset including size, material type, and other attribute data, were also collected as the asset inventories were developed. A summary of the data and information collected for each asset is described in the following Section. There were six essential pieces of information common to all assets developed during the inventory process: 1. Asset identification — a unique number assigned to each asset based on the City's standard asset numbering convention. 2. Year installed and asset age — age is a critical factor in evaluating the current state of an asset relative to its overall life cycle. 3. Asset material or Manufacturer — asset material and manufacturer are used as an indication of common deterioration or aging characteristics. 4. Asset useful life — average useful life data were developed based on industry standards adapted for the San Marcos reuse system by operations and maintenance staff. 5. Asset remaining useful life — Average useful life minus the current asset age. 6. Asset replacement value — A replacement value was estimated for each asset and included in the overall inventory. The asset inventory effort created an essential first snapshot of data and information required to manage the San Marcos' infrastructure on an asset - centric basis. Much of the inventory data compiled for the San Marcos reuse system pipeline assets were gathered from information in the existing San Marcos GIS database.
