Flowing Towards Excellence: ISE in Water/Wastewater Utility Evaluation

This paper explores the transformative impact of adopting an Industrial and Systems Engineering (ISE) centric approach in the evaluation of water/wastewater utilities, using the case study of DC Water's mandated five-year independent engineer's assessments. The 2018 report and its predecessors were traditionally led by civil engineers, while the 2023 evaluation witnessed a paradigm shift, entrusting the lead to a Professional Industrial Engineer and a lead investigator with an Operations Research MBA. Highlighting the divergence in methodologies, the study underscores the heightened value derived from an ISE-centric perspective. Key differences include the implementation of tailored questionnaires, both quantitative and qualitative self-assessments, enhancing the depth and breadth of data collected, and the adoption of prespecified criteria ensuring a more rigorous and objective reporting process during site visits. Furthermore, benchmarking practices were integrated into the assessment to evaluate and effectively communicate the quality of utility management. A notable innovation in the 2023 evaluation was the incorporation of historical and forecasted capital expenditures, providing a comprehensive context for understanding findings. The paper emphasizes the significance of including a detailed management and operations evaluation, offering valuable insights for utility management. This shift toward an ISE-centric framework showcases a holistic approach that transcends traditional engineering boundaries, presenting a dynamic model for future utility evaluations, optimizing system operation and maintenance, and facilitating informed decision-making for infrastructure enhancements.
