Aqua Illinois-Hawthorn Woods is a public water system in Illinois. Backflow preventer assemblies on its distribution system must be tested by a certified tester and the test report filed with the purveyor — here is how filing works.
Aqua Illinois-Hawthorn Woods takes backflow test submissions through its own online portal. Testers enter each test in the portal themselves — no bulk upload exists for any portal vendor — so BackflowGo preps your re-key sheet (every value in the portal's entry order) and routes you to the utility's own online portal to file.
Illinois does not mandate a single statewide test form. Most purveyors accept the standard USC/AWWA-style report, which BackflowGo generates — requirements live at the purveyor level.
Listing data is sourced from the EPA SDWIS federal registry and BackflowGo's own purveyor research. All Illinois water systems →
