2 What is asset management and why should I care about it?

3 Asset Management Defined Asset management offers an approach to managing infrastructure assets to minimize the total cost of ownership, while delivering reliable service to customers, at acceptable levels of risk.

4 Why should I care? Regulatory Requirements Reduce headache / frustration Minimize politics Effectively allocate time and resources on a day to day basis

5 What is my required sustained level of service? Based on previous, what is my best long-term funding strategy? Which of my assets are critical for sustained performance? What are my best minimum lifecycle cost CIP and O&M strategies? What is the current state of my assets?

6 Level of Service Funding Critical Assets Lifecycle Cost Current State

7 Level of Service Funding Critical Assets Lifecycle Cost Current State

8 What is my required sustained level of service? Mission: Provide reliable wastewater collection and treatment services at a minimum cost, consistent with applicable environmental and health regulations.
