Water Infrastructure and Capacity Assessment Tool

What types of water infrastructure are included within Water ICAT?

Water ICAT currently focuses on: (1) Community Water Systems (CWS) for drinking water data, and (2) National Pollutant Discharge Elimination System (NPDES) permitted Publicly Owned Treatment Works (POTWs) for wastewater data.  

The limiting factor in not including other infrastructure types (such as, municipal separate storm sewer systems (MS4s), private domestic wells, septic systems, and non-discharging wastewater facilities) is a lack of national data availability. As data availability improves, more water infrastructure types may be added to this tool. 

For more information, visit Infrastructure Types within Water ICAT.

What types of data are included in Water ICAT?

Water ICAT includes four primary types of data: (1) General Utility Characteristics, (2) Community Characteristics, (3) Enforcement/Compliance Characteristics, and (4) Water Infrastructure Funding History.

1. General Utility Characteristics: Includes baseline utility characteristics, such as, location, population size served or utility size, infrastructure type (for wastewater).
2. Community Characteristics: Includes environmental justice, disadvantaged community, and other socioeconomic/demographic characteristic data. These data are included for utilities when adequate spatial data are available to know the actual or approximated service area for a utility. These data provide insight into the population that comprises a utility’s (actual or approximated) service area.
3. Enforcement/Compliance Characteristics: Includes compliance data for the most recent official reporting period AND historical compliance data. A facility’s enforcement and compliance history can be used to analyze trends and provide users with additional information on key activities.
4. Water Infrastructure Funding History: Includes State Revolving Fund (SRF) data for the last 10 years. Past receipt of SRF funding can provide insight into a utility’s capacity to successfully identify, apply for, and receive funding, although it is important to note that there are other sources of infrastructure funding that are not included within Water ICAT.

What spatial data are used to map utilities and characterize their service area?

Water ICAT uses the best available spatial data to map water utilities and characterize population characteristics within a utility service area or utility proximity.

• Drinking Water: Water ICAT incorporates spatial data in two ways for drinking water systems: (1) Water ICAT uses EPA’s Community Water System Service Area Boundary data, when available. (2) When not available, reported data on the county, tribe, or territory served are used, and a point is placed at the centroid of that reported area. Only systems with service area boundary data have population characteristics available within Water ICAT.
• Wastewater: Unlike drinking water systems, wastewater facilities in Water ICAT do not have nationally available service area boundary data layers. In the absence of these data, wastewater facilities are displayed as points referring to the locations of the wastewater treatment plants, as reported within ICIS-NPDES (Integrated Compliance Information System-National Pollutant Discharge Elimination System). In the absence of spatial boundary data, Water ICAT calculates population characteristics within a one-, three-, and five-mile buffer around the facility.

What are some of the use cases for Water ICAT?

The purpose of Water ICAT is to identify utilities that may need technical assistance. When using Water ICAT, users identify utilities with potential assistance needs by selecting map filters meeting their screening requirements.

Based on the results, users can then ground-truth actual utility needs by consulting more local information at the state, community, or utility-level.

After verifying actual need, the process of working with utilities to access beneficial resources, such as, support through EPA’s WaterTA, can begin.

More information on uses of Water ICAT can be found within the app under Appropriate Uses, and user guidance can be found under Quick Start Tips.

How often is data within Water ICAT updated?

Water ICAT always aims to have the most up-to-date data populated within the tool, remaining in-sync with source data updates. Some data, such as, compliance data, are updated quarterly, other data, such as, state revolving fund data, are updated annually. Users can verify the latest compliance data on EPA’s Enforcement and Compliance History Online platform.

Details on data extraction frequencies, data extraction date, and expected next update can be found within the Water ICAT App under Source Data and Field Names.

What are some caveats and limitations?

Water ICAT provides technical assistance providers and related entities a data-driven resource to screen for water utilities that may have water infrastructure or capacity development needs and may benefit from related assistance.

Some caveats and limitations of Water ICAT include:

1. Need is a broad term used within Water ICAT, intended to encompass different types of support a utility may benefit from. Not all utilities identified using this screening tool may require assistance.
2. Water ICAT is just one of several resources that can be used to identify potential need and is intended to complement existing resources.
3. Water ICAT incorporates enforcement and compliance data, however, Water ICAT is not intended to be used as an enforcement targeting tool.
4. Water ICAT incorporates screening level data that users should supplement with additional, more localized, information to discern actual need.
5. Not all utilities have adequate spatial or locational data to discern community characteristics.
