Trinity River Authority CYA: Conserve Your Assets Systematic Approach to Successful Plant Rehabilitation

Trinity River Authority (TRA) operates a 189-mgd capacity plant in Grand Prairie, Texas. The plant experiences highly corrosive environments and the equipment and structures have deteriorated since the original construction in mid 1970's. An assessment conducted in 2006 identified approximately $60 million in rehabilitation needs plant wide. The rehabilitation needs required an innovative approach in order to address the needs in a cost effective and timely manner to achieve the project goals. TRA implemented a proven step by step asset management approach to address the rehabilitation needs. Structures and equipments were prioritized in multiple phases. Scope items within each phase were consolidated into multiple bid packages to maximize the project efficiency and impact on plant operations and to accommodate budget constraints and specialty projects. The rehabilitation assessment and improvement process is continually identifying and addressing additional plant rehabilitation needs, which allows TRA to effectively and comprehensively manage and conserve their assets.
