How to submit a backflow test report to Sylvan Lake 1ST Subdivision
Sylvan Lake 1ST Subdivision 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.
How to file your backflow test report
Sylvan Lake 1ST Subdivision accepts backflow test reports by email. BackflowGo has the report inbox on file — enter your test readings once and BackflowGo submits for you in one tap: the platform fills the correct official form, attaches the PDF, and emails it straight to the purveyor's cross-connection program, with a copy for your records.
Filing on your own? Ask the utility for its backflow report submission address, then send the completed test form within your jurisdiction's deadline.
The Illinois form requirement
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.
