There are two ways to access the tool:

1. Use the tool online at
2. Download the Microsoft Excel version of the tool specific to your state:
   • Kansas
   • Iowa 
   • Nebraska
   • Missouri 
   • Oklahoma

Both versions of the Community Sustainability Tool will produce the same results. The online tool provides helpful prompts and user-friendly features, making it a great option if you are new to the tool, or just trying it out. The Microsoft Excel version of the tool allows users to access the tool offline and save different scenarios.

 

The Community Sustainability Tool is designed to inform municipal utility managers, local officials, municipal finance officers, state regulators, technical assistance providers, and more, by analyzing a community's ability to sustainably finance water utility infrastructure investments into the future. The tool is currently available for communities in Kansas, Iowa, Nebraska and Missouri.

Users can quickly access the Community Sustainability Tool with an internet browser and high-speed internet connection OR users may download the Microsoft Excel version of the tool, which allows users to operate the tool offline and save different scenarios.

Although the tool is programmed with data from the U.S. Census Bureau's American Community Survey, communities will need to collect the following key inputs:

• 颅Average household monthly drinking water bill in dollars
• Annual growth rate percentage of drinking water bills* 
• Average household monthly wastewater bill in dollars
• Annual growth rate percentage of wastewater bills* 
• Planned expenditure on drinking water infrastructure. Specifically, the amount that will be financed.
• Number of years drinking water infrastructure will be financed
• Planned expenditure on wastewater infrastructure
• Number of years wastewater infrastructure will be financed
• Annual interest rate of the loan (If unknown, a default interest rate will be provided by the tool.)

* The current annual growth rate in water/wastewater bills should incorporate all projected cost increases EXCEPT for those associated with the debt payments on infrastructure.

For more info about how to use the tool, check out the Community Sustainability Tool User Guide, or watch the or videos.

WSU Environmental Finance Center's Community Sustainability Tool uses a combination of user data and program-generated forecasts to broadly predict the future average water bill needed to sustain utility investments. The tool also shows the ability to sustain infrastructure investments in relation to the community鈥檚 forecasted median household income. The tool can be used as a decision-making guide for further investigation into a community鈥檚 proposed water utility infrastructure investments.

The tool uses variables from the U.S. Census Bureau to estimate a community鈥檚 median household income. These tool-generated variables include current median household income, population, education attainment and percent of jobs in the manufacturing sector. Then, users provide key inputs specific to the community and proposed infrastructure investment. These key inputs include the average consumer drinking water and wastewater bills, cost of the planned water/wastewater infrastructure to be financed, and terms of the infrastructure loan (years financed and interest rate).

The tool then works by generating an estimated average drinking water/wastewater bill needed to sustain the investment. The tool also assesses the likelihood that the community's rate payers will not be able to sustain financing the loan. 

The tool visualizes the results with an easy-to-read, color-coded stoplight risk analysis, graph and detailed numerical description. The tool's stoplight risk analysis will indicate a probability marker as 鈥淗igh,鈥� 鈥淢oderate,鈥� or 鈥淟ow鈥� sustainability risk.

High (displayed in red) 
High risk indicates that there is a greater than 66% probability that the community will not be able to sustainably finance the investment over time.

Moderate (displayed in yellow)
Moderate risk indicates that there is somewhere between a 33% and 66% probability that the community will not be able to sustainably finance the investment over time.

Low (displayed in green)
Low risk indicates a less than 33% probability that the community will not be able to sustainably finance the investment over time. 

 

 

WSU Environmental Finance Center's Community Sustainability Tool is a financial planning resource for community decision makers.

The tool's uses include the ability to:

• Plan future infrastructure investment
• Evaluate how sustainable current rates are with investment
• Assess sustainability of both water and wastewater investments
• Examine potential scenarios based on different investments
• Forecasts various community metrics

The Community Sustainability Tool should not be used to:

• Justify existing water/wastewater rates
• Determine reserve account sufficiency
• Determine how much investment is needed
• Separate out sustainability by user type

The Community Sustainability Tool has several assumptions and limitations:

• This tool uses data from the U.S. Census Bureau鈥檚 American Community Survey. If your community is not identified by the American Community Survey, this tool will not be able to produce outputs for your community.
• This tool provides estimates at the community level only. The estimates may or may not reflect the entire customer base for a water and/or wastewater utility. The tool is designed to assess the typical household or residential customer account. It does not differentiate between customer types or water user rate types (e.g., residential, commercial, etc.).
• Additional limitations are discussed in the .
