Applying a Strategic Asset Management System in Tulsa

In its Comprehensive Assessment of Water and Wastewater Facilities, the Tulsa Metropolitan Utilities Authority (TMUA) has significantly enhanced the ability to effectively manage its system-wide assets and laid the groundwork for an ongoing asset management program. The Assessment, which involved master planning for the wastewater collection system, wastewater treatment plant facilities, water transmission and distribution system, and water supply system involved the implementation of risk-based asset planning and prioritization to support the development of a system-wide capital improvements program. A highlight of the project was the update of TMUA's Strategic Asset Management System (SAMS) planning tool for the wastewater treatment facilities. This presentation will provide an asset management case study highlighting the successful implementation of a risk-based prioritization tool that links directly with the Computerized Maintenance Management System (CMMS) to facilitate regular updates and reports needed to support the Utility's budget cycle. All condition assessment criteria are now maintained in the CMMS system, and the BRE calculations are performed in the new SAMS tool. Flexibility was built into the risk analysis to build on TMUA's experience and to allow changes in the BRE calculations as the TMUA gains experience. This work laid the foundation for comprehensive asset management improvements now underway throughout the Water and Sewer Department.
