Tennessee Wastewater Operator Practice Exam

What does life-cycle cost analysis take into account?

1. Energy efficiency only

2. Operational costs exclusively

3. Total cost of ownership of equipment

4. Initial purchase price only

The correct answer is: Total cost of ownership of equipment

Life-cycle cost analysis is a comprehensive method for assessing the total financial implications associated with a piece of equipment or system over its entire lifespan. This approach encompasses not just the initial purchase price, but also factors in operational costs, maintenance expenses, energy consumption, and potential disposal costs at the end of its useful life. By focusing on the total cost of ownership, this analysis provides a more informed perspective on the long-term financial commitment involved in acquiring and maintaining equipment. This is crucial for wastewater operators who must ensure that the systems they implement are both cost-effective in the short term and sustainable over many years. The life-cycle cost analysis ultimately enables better decision-making, leading to more efficient use of resources and budgeting for wastewater facilities. In contrast to focusing narrowly on energy efficiency, operational costs, or the initial purchase price alone, which do not provide a complete picture, assessing the total cost of ownership ensures a thorough understanding of the financial implications of equipment decisions in wastewater management.
