Explanation of Terms on Your Water Inventory Form
Each section of the Illinois Water Inventory Program’s water inventory form helps us accurately track water use across Illinois. Use the descriptions below to check your information before submission.
| Term | Description |

For public water systems, this number matches your Illinois EPA ID, with a “9” added in the fourth position. |
