Description
The Asset Management concept has matured greatly in the water/wastewater industry but specifically for linear assets that leverage Geographic Information Systems (GIS) to visualize where assets are along with attribute and operational data. Leading utilities Fairfax Water and Hampton Roads Sanitation District have been developing and refining their asset management programs over the years to include vertical and electromechanical assets and to ensure maintenance activities maximize overall system reliability and optimize asset life-cycle operations.

Fairfax Water has been developing and refining its asset management program to ensure maintenance activities maximize system reliability and optimize asset life-cycle costs. Fairfax Water applies maintenance strategies appropriate to the vertical electromechanical asset’s condition, performance and criticality with the goal of avoiding costly reactive maintenance and minimizing risk to production. 

Fairfax Water will discuss the major condition-based and predictive maintenance activities practiced to include vibration, oil condition, thermal, and performance. Testing frequency, equipment used, and manpower training necessary to support an effective CBM and predictive maintenance will also be discussed. Recent lessons-learned on how an asset management system must adapt will be illustrated for specific pump station electromechanical assets. There will also be discussion about how to use CBM data to manage utility’s perspective on what constitutes an equipment failure.

Vertical assets (Pump Stations, Treatment Plants, and Administrative Facilities) have used Computerized Maintenance Management Systems (CMMS) as an asset register as well as a means to manage maintenance activities, track failure history, etc. CMMS has been essential for utilities to digitize maintenance history but the lack of visual representation of a facility limits the operator’s ability to manage assets properly. 

The Hampton Roads Sanitation District (HRSD) operates 17 wastewater treatment plants and over 100 pump stations. GIS has been a powerful tool for field staff to navigate to assets, identify failure history, collect condition data, and even monitor flow and pressure data. HRSD wanted a similar process for treatment plant and pump station operators. 
HRSD will discuss development of a digital twin of their interceptor and treatment systems in addition to a Business Intelligence (BI) platform used to report maintenance, condition, risk, and replacement planning information. The data is archived in its respective system of record (GIS, CMMS, etc.) and the BI platform pulls the data and performs backend calculations in order to determine the remaining useful life and replacement year for each asset. Key Performance Indicators are now monitored at various levels of the organization to improve operations and maintenance. A Condition Assessment protocol was developed for vertical assets to standardize the data collection and reporting.
