Asset Inventory Guidance
To receive additional points in the project questionnaire for having an asset inventory, the following information is required:
- List of water system assets
- Age of assets
- Expected life of the assets
- Criticality
- Level of service
- Replacement costs
The worksheet developed by Rural Community Assistance Corporation (RCAC) can be used to submit this information. The template can be found at RCAC’s website. You are not required to use the RCAC spreadsheet to receive bonus points; other formats are acceptable.
Instructions
Column A: Asset and Description
List your water system assets here. Assets to list include pumps, wells, storage tanks, pipes, treatment facilities, and vehicles.
Column C: Installed Date
Enter the date you believe the asset was first put into service.
Column D: Estimated Effective Life
Enter the expected life of the asset in years in this column. For this spreadsheet, the condition rating (Column E) is applied to determine the calculated remaining life of the asset.
The table below may help you estimate the expected life of an asset. You can also get information on the life of an asset from equipment operating manuals, water systems operators, or vendors.
| ASSET TYPE | AVERAGE EFFECTIVE LIFE (Years) |
|---|---|
| Intake Structures | 40 |
| Wells/Springs | 40 |
| Chlorination Equipment | 7–10 |
| Small Motors | 10–15 |
| Storage Tanks | 60 |
| Pumps | 10–15 |
| Pipe | 60–90 |
| Valves | 20–30 |
| Backflow Devices | 15–20 |
| Meters | 10–15 |
| Hydrants | 30–45 |
| Lab Monitoring Equipment | 5–10 |
| Tools & Shop Equipment | 10 |
| Office Furniture | 10 |
| Computers | 5 |
| Vehicles | 10 |
| Civil Structures | 75 |
| Electrical Motors (large) | 30 |
| Electrical Panels | 20–25 |
| Controls | 15–25 |
| Building Assets | 60 |
Column F: Criticality
Each asset must include a criticality number to receive bonus points for having an asset inventory. Criticality depends on the impact to the water system if the asset is not available. The RCAC spreadsheet uses the following critical numbers.
| CRITICAL NUMBER | DESCRIPTION |
|---|---|
| 1 | The water system will essentially shut down if this component fails. This asset has no backup and is so important that an emergency plan must be in place as well as funding to replace it. Example: Single well pump failure; single reservoir failure; anything that could cause a violation of the Safe Drinking Water Act. |
| 2 | This asset would have a serious impact on the water system if it failed; however, procedures could fix the problem within a reasonable time. Example: Two wells and primary well pump fails; electrical components in panels fail; backflow assembly did not pass testing; key pipe failure that could be repaired; single chlorinator failure; pressure reducing valve failure. |
| 3 | The condition of this asset causes continued unnecessary operational costs to your utility. Examples: Deteriorating buildings, equipment and rolling stock; leaks in piping; old and worn-out electrical equipment. |
| 4 | This asset's condition or failure may cause inconvenience to customers via reduced service, outages, or minor taste or odor complaints. Examples: Excessive leaks, valves frozen partway closed, hydrants not working so flushing cannot be done; poor billing program. |
| 5 | These assets have been in service for a long time, and their condition may not be well known. Evaluation recommended to determine what may be needed. |
Column Q: Replacement Cost
Each asset must have a replacement cost provided.
