Life Cycle Costs for Wastewater Pumping Systems

This white paper discusses the life cycle costs (LCC) associated with wastewater pumping systems, emphasizing the importance of a comprehensive evaluation beyond initial purchase price. It outlines that the purchase price typically represents less than 10% of the total LCC, which includes energy consumption, maintenance, downtime, and environmental penalties. The document utilizes the Hydraulic Institute (HI) framework to provide a detailed LCC analysis, highlighting critical factors such as initial investment, energy costs, and maintenance costs. It explains how local circumstances can influence the weighting of these factors, and it emphasizes the necessity of focusing on the most relevant costs for specific pump systems. Additionally, the paper presents the LCC formula defined by the Hydraulic Institute and discusses various cost categories, including operational and decommissioning costs. Recommendations for optimizing pump system design and minimizing total costs are included, making it a valuable resource for decision-makers in the wastewater sector.
