Asset Management – Balancing Program Constraints

The San Francisco Public Utilities Commission is implementing its Sewer System Improvement Program (SSIP) to improve its collection and treatment facilities. Extensive improvements to its Southeast Water Pollution Control Plant are included in the Program, including replacement of many of its solids and liquid treatment facilities. Many of the plant facilities currently require improvements to maintain reliable operation, yet will be replaced in 5-10 years. A condition assessment and prioritization project was initiated to plan improvements. This presentation describes the approach and tools used by the SSIP Condition Assessment Program to address these issues. The work on this project ranged from a condition assessment of over 70 facilities on the plant site to a risk-based prioritization approach. The use of external database tools to provide flexibility and overcome functional gaps in existing asset management systems was a key to the success of this project.
