Illinois Water Inventory Program

About the Program

The Illinois Water Inventory Program (IWIP), founded in 1978, is a state-wide inventory of water use and withdrawals in the State of Illinois. The priority of the program is to develop and maintain a database of high-capacity water wells and intakes from public water supplies, self-supplied industries, irrigation, fish and wildlife, and conservation. A high-capacity well or intake is any well or intake that is rated to pump 70 gallons per minute (gpm) or greater. In addition, any facility which owns or operates multiple wells or intakes which when combined are rated to pump 70 gpm is classified as a high-capacity operation. For each water-using facility inventoried, the database includes locations and amounts of water withdrawn from surface water and groundwater sources, as well as significant amounts of water purchased from other facilities. Data can be summarized geographically by county, township, and drainage basin, as well as by various water use and water source categories for inclusion in publications of the USGS National Water Use Program. Annual submission of the Illinois Water Inventory form is mandatory according to Public Act 096-0222 (viewable online here).

Registration and Annual Reporting

Agricultural Irrigation Facility Reporting

Irrigation Reporting Information is now available online. The webpage provides the following information:

  • A downloadable irrigation handbook which includes forms and guidance for record-keeping, calculating, and reporting irrigation water use.
  • Information on how to register an agricultural irrigation facility in IWIP
  • Help on calculating annual gallons of water withdrawals
  • Instructions on how to report water use information.

Please note, IWIP considers an Agricultural Irrigation facility to be a crop irrigation facility which typically irrigates with a center pivot irrigation system. This does not include golf courses or nursery facilities.


Public Water Supply and Industrial-Commercial Facility Reporting

Public Water Supply and Industrial-Commercial facilities will receive a postcard notification in the mail in early March of 2019, with instructions on how to report the previous year’s water use and withdrawals data.

Lake Michigan Ordinance (LMO-2 Recipients): Facilities that have a Lake Michigan allocation are required to submit a form (the LMO-2) to the Department of Natural Resources’ Office of Water Resources in Chicago. LMO facilities must still report Water Use Information to IWIP, however these facilities may report water use on the previous federal water year, which runs from October 1 through September 30.

Please note golf courses and nurseries are considered to be Industrial-Commercial facilities, and not Agricultural Irrigation facilities as defined by IWIP. As such, these facilities should have been reporting to IWIP annually since 2010.

Online Reporting

IWIP reporting can now be done online via the IWIP Online Reporting Tool.

To use the tool, facility operators must first register an account with IWIP staff, and receive a unique Username and Password. To begin this process please send an email containing facility name, facility number (if known) and your contact information to ISWS-IWIP@isws.illinois.edu

If you already have a Username and Password for your facility, you can access the online tool for your facility type with the links below:
