The manhole feature class includes Diversion Box, Junction Box, and Manhole.The GIS Services Group of Houston Water, Houston Public Works currently stores and maintains the dataset within a Relational Database Management System (RDBMS). 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 manhole geospatial layer provides quality geospatial data of the City of Houston’s sewer collection system to wastewater Operations. 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.

The accuracy of the attributes is based on information obtained from Plan and Profile Engineering Drawings that come 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. Logical consistency is performed using the Utility Network Analysis and the ArcFM Valence Renderer tools that check for network connectivity errors. All available data from Plan and Profile Engineering Drawings obtained 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 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.
