Backflow Tests Due July 31, 2024

TCPUD Customers with a Backflow Device on Your Property: You likely received a ‘First Notice to Test’ reminder for the 2024 testing cycle. TCPUD sends notices by March 31 every year, regardless of snow load. Notices are sent by email and postal mail.

All Backflow tests are due July 31, 2024. This date should allow the snow to melt so you can safely test outside devices, including ones found on irrigation systems.
