Risk-Based Decision Support System for U.S. Air Force Water and Wastewater Infrastructure Asset Management

Despite the large quantities of utility infrastructure data and various DOD processes, there was no management of that data in a central repository where it could be analyzed effectively for asset management. U.S. Pacific Air Forces (HQ PACAF/A7OP) engaged AECOM to develop and implement risk-based decision support for their wastewater infrastructure asset management. A consistent, repeatable approach for infrastructure requirements prioritization and investment across PACAF’s portfolio of installations was developed and implemented for over nine installations worldwide. The risk-based decision support system utilizes a GIS platform with ArcGIS software, along with CartoPac (a data collection/management tool). Relational databases were developed for PACAF for each type of infrastructure, to include attributes, that will store the probability of failure and criticality data for each asset. These tables relate and join to the DOD’s spatial data standards for facilities, infrastructure, and environment (SDSFIE) GIS structure. SDSFIE attributes are recorded to that geodatabase, while additional conditions and operational data are recorded in relational databases. Sub-meter GPS-enabled devices were used to map the water assets. Visual condition assessment surveys were conducted and supplemented with engineering analysis such as hydraulic modeling. Visual condition assessment surveys were conducted and supplemented with tools such as polecams, CCTV cameras, and flow monitors. A reporting service called business intelligence and reporting tools (BIRT) was developed to be used in a server enterprise environment. Report templates are informed by the underlying GIS and risk scoring data and are updated in real-time. The system provides the DOD with information required to rationally address high-risk requirements, gradually upgrade systems to required levels of service, and improve O and M management.
