How GIS Helps Utilities Streamline Asset Management

Now, more than ever, communities and utilities are benefitting from asset management programs (AMPs). No matter how simplistic or complex the systems, having instant and remote access to one’s water, wastewater and stormwater asset data has never been more valuable. We are in a time when crew staffing is limited, however, asset maintenance and operations activities must be carried out. Fortunately thanks to Geographical Information Systems (GIS) based asset management, virtual connectivity with assets and communication with operations staff is easier than ever.
Whether working remotely, at the office, or in the field, utilizing GIS-based asset management allows directors, superintendents, managers, operators and other staff to access vertical and horizontal asset inventory records, inspection logs, as-built plans, tie-cards, work orders, maintenance history, and more at their fingertips. This is thanks to GIS-based asset management applications that are accessible on smart phones and tablets.
Asset management helps communities identify and capture what assets they have, where they are located, the condition of the assets, replacement costs, and more. The following table highlights some beneficial uses of GIS-based asset management for drinking water, wastewater, and stormwater systems.
|Daily Operations Benefits||Records & Planning Benefits|
|Wastewater||• Pump station inspection forms|
• Assign and complete work orders
• Manhole inspections
|• Remote access to digital record plans, tie cards, photos of repairs
• Prioritizing capital improvements at WWTF
• Capture seasoned workers’ institutional knowledge
|Drinking Water||• Backflow Preventer Inspection |
• Well site & pump station rounds
• Meter Orders
|• Records plans and service connections
• Hydrant flushing & valve exercising programs
• Capture institutional system knowledge
|Stormwater||• MS4 Compliance |
• Catch basin cleaning
• Outfall inspections
|• Identify areas with frequent flooding
• Prioritize catch basin cleaning based on debris buildup
Using Asset Management Plans for Defendable Risk-Based Capital Planning & Rate Impacts
Risk-based prioritization is an important component of the AMP, where assets are ranked based on consequence of failure (CoF) and likelihood of failure (LoF). Stakeholders perform a risk or criticality analysis to consider the consequences should an asset fail; how many customers will be without service? Will critical infrastructure like bridges or major interactions be compromised? Would travel to/from critical facilities like hospitals or fire stations be impacted? Assets that have a higher risk or criticality score receive increased maintenance/observation and are prioritized for repair or replacement.
Utilities can then consider how this asset maintenance, rehabilitation or replacement activities will impact rates and working capital. User rate increases are justified and defended by the criticality analysis.
Funding Asset Management Plans
Many New England states have funding programs to support the development or advancement of asset management or fiscal sustainability plans. The following table describes some of these programs.
|State||Utility||Funding Type & Match Requirements||Maximum Total Project Cost||Program Website|
|Grant – 60% |
In-Kind Services – 20%
Cash Match – 20%
|NH||Water||Grant with 100% Cash or In-Kind Services Match||$40k||https://www.des.nh.gov/organization/divisions/water/dwgb/asset-managment/index.htm|
|NH||Wastewater Stormwater||Principal Forgiveness|
|ME||Wastewater Stormwater||Principal Forgiveness with 100% Cash Match||$100k||https://www.maine.gov/dep/water/grants/srfparag.html|
|CT||Wastewater||Planning Grant – 55%||Varies||https://portal.ct.gov/DEEP/Municipal-Wastewater/Financial-Assistance-for-Municipal-Wastewater-Projects|
As our industry faces the new challenges of social distancing and staffing limitations, Asset Management Plans, and the implementation of GIS technology is key. By assessing risk, utility operators can prioritize maintenance to minimize emergency repairs in a time of limited resources. Using an AMP and the accessibility to records and operations documents creates a streamlined approach to daily operations that takes strain off employees and sets the facility up to serve their communities without service interruptions or water quality issues.
