Water System Preventative Maintenance
Public Utilities Commission
Target: 95% of total water system maintenance time
Status: NOT MEETING TARGET
Result: 90.3% of total water system maintenance time
This measure represents the percentage of water system total maintenance time that the San Francisco Public Utilities Commission (SFPUC) devotes to planned maintenance as opposed to corrective maintenance. It quantifies the SFPUC’s efforts regarding proactive versus reactive maintenance. This indicator is one way to measure the performance of SFPUC’s infrastructure, and the agency anticipates that the percentage of time spent on reactive maintenance will fall as older assets are replaced.
WATER SYSTEM MAINTENANCE TIME DEVOTED TO PREVENTATIVE MAINTENANCE DECREASED SLIGHTLY FROM FY 2014-15 TO FY 2015-16
How the Public Utilities Commission is Performing
A comprehensive maintenance program ensures that SFPUC can continue to provide reliable water services to its customers. Maintenance funding is generally derived from operating capital, and new infrastructure projects are funded by capital funds, as adopted through the Water Enterprise Capital Improvement Program.
Maintenance tasks are categorized by priority level. Priority levels eight and nine are the highest level of urgency, and require workers to leave otherwise scheduled work in order to attend to this work. Priority eight and nine work is generally reactive, including urgent maintenance that must be addressed immediately, like main breaks. In fiscal year (FY) 2013-14, SFPUC dedicated staff to work with all three utility Enterprises and supporting Bureaus to establish a program framework, set multiple year targets and standardize SFPUC’s organization-wide asset management. In FY 2014-15, all water divisions started using a standardized system for tracking maintenance hours. The agency is now calculating this metric by measuring the hours spent on priority eight and nine work against the total hours of maintenance worked. The slight decrease from FY 2014-15 to FY 2015-16 is due to SFPUC's Citywide Distribution Division (CDD), as there were numerous main breaks in the cityover the past fiscal year. Hetch-Hetchy and Water Supply & Treatment had higher ratio numbers.
Note that prior to FY 2014-15, divisions within the Water Enterprise used different methodologies for categorizing planned versus reactive work. Therefore, older data may have internal inconsistencies.
How Performance is Measured
This measure represents hours of planned maintenance divided by total hours of maintenance, comprised of planned and corrective maintenance, multiplied by 100.
