Wastewater Plant Condition Assessment: Methods and Results

As Water Reuse and Recovery Facilities (WRRFs) encounter critical decisions on how best to deal with aging infrastructure and an uncertainty on future regulations, a vision on how to integrate condition assessment and technology evaluation can provide invaluable data for informing such wide ranging business decisions. This paper details the initial planning and evaluation phase (how a condition assessment should be performed), the inspection phase (how equipment was inspected), and the engineering analysis phase (evaluating the impact of current conditions) during condition assessment. A case study is provided as a template for others to use for evaluating the remaining useful life of critical equipment and highlight ways in which a condition assessment can improve reliability, extend equipment useful life, and reduce operating costs.
