The GIS Services Group of Houston Water, Houston Public Works currently stores and maintains the dataset within a Relational Database Management System (RDBMS). This geospatial layer provides information about the locations and attributes of abandoned wastewater lines within the City of Houston’s wastewater collection system. This point feature class supports the city’s work management systems (IPS: Infor Public Sector; IMS: Infrastructure Management System), and web application (GIMS: geographic Information Management System). The geospatial dataset was officially published with the Geographic Information Management System (GIMS) on October 31, 1997 (Hudson and Fischer, 1999; Fischer and Hudson, 2000). However, the City of Houston’s effort to create its core geospatial infrastructure database dates back to 1989. Prior to 2009, the geospatial dataset was created and maintained within ArcInfo coverage. This dataset only contains geospatial data for the City’s public water distribution system, with a temporal coverage dating back to 1910. As the city grows and infrastructure ages, the geospatial dataset is being continuously updated with new construction, and ongoing maintenance data. According to the City of Houston Infrastructure Design Manual (Rudick and Lincoln, 2016), all wastewater lines and appurtenances are digitized within the public Right-Of-Way or a dedicated public easement.

ArcGIS Software Desktop10.2.1, ESRI; ArcFM Solution 10.2, Schneider Electric All wastewater collection lines are identified in the Plan and Profile Engineering Drawing, and abandoned in either a separate ArcFM session or while digizing existing data. A quality assurance process is performed to ensure that allabandoned wastewater collection lines with their corresponding attributes shown in the Plan and Profile Engineering Drawings were accurately digitized and recorded in the production database before being forwarded to a supervisor. The ArcFM session is then posted by a supervisor in the production database. The dataset is then replicated from the production environment to relative replicated databases every night before being distributed to other divisions within the City of Houston. City of Houston, Department of Public Works and Engineering, Houston Water, GIS Services The data are derived from Plan and Profile Engineering drawings obtained from Block Map, As Built, Field Book, Taps and Meters, Metro, Autocad Data from GHW Project, Wastewater Reconciliation Project, Other Source (Operator Input), FVFL, FVFD, Field Verified with Control Number, and Construction Layer. The dataset is maintained by the GIS Services Group of Houston Water. The attribute information is taken directly from the Plan and Profile Engineering Drawings. Logical consistency is performed using the Utility Network Analysis and the ArcFM Valence Renderer tools that check for network connectivity errors. All data available (locations and attributes) from Plan and Profile Engineering Drawings within the City Limits of Houston are included in the dataset. The general location of the data is based upon the plan and profile paper drawings. The general location of the data is based upon the plan and profile paper drawings.
