A Practical GIS Tool for the PCCP Operator

The Tarrant Regional Water District is a political subdivision of the State of Texas formed in 1924 with the purposes of water supply and flood control. One of the largest raw water suppliers in the state, the District serves over 30 wholesale customers, including Fort Worth, Arlington, Mansfield, and the Trinity River Authority of Texas. The District owns four reservoirs and utilizes three others for terminal storage. The District's activities span a 10-county area of North Texas from Jack County to Freestone County. The District operates in excess of 160 miles of prestressed concrete cylinder pipe (PCCP) and experienced the first of a series of failures in 1981. Since that time, the District has implemented a number of condition assessment and risk mitigation measures that have resulted in an improvement in the reliability of the pipeline. These measures also resulted in the collection of a diverse range of data sets. In order to utilize this information, the district turned to the Pressure Pipe Inspection Company. This paper describes the development and implementation of a geographic information system (GIS), created for owners and operators of PCCP lines for use as an Asset Management System. The system incorporates custom variable sets to provide an up-to-date view of an operator's existing water pipeline infrastructure. The system further integrates inspection/integrity information while maintaining the hydraulic modeling capability of typical pipeline models, providing a foundation for informed decision making.
