Wastewater Pipe Risk-based Prioritization and Maintenance
Track: Water, Wastewater, and Stormwater
Authors: Ariana Wilfley
As part of its asset management strategy, Santa Ana Public Works must efficiently schedule sewer assets for regular, preventative maintenance while also avoiding asset failure. Using limited resources, the Department must prioritize wastewater pipes for cleaning based on many factors, including pipe age and material, previous cleaning observations, and structural or maintenance issues. A GIS model used these parameters to establish a cleaning schedule and determine when a pipe will be cleaned.
