The State of Minnesota requires backflow preventer assemblies on all in-ground
irrigation systems. The testing of all irrigation system backflow preventer devices must be
completed each year, preferably at the time of the system start-up.
Shakopee Utilities requires all backflow device be tested annually, which is quite smart as the older ones have more failures.
State law only requires testing of units installed after January 23, 2016.
This isn't national plumbing code nor recommened by the manufactures of backflow devices. Annual testing should be for all testible backflow devices, this could open city and water suppliers to legal issues and possible insurance coverage issues, because once the water leaves there water plant. They have no idea if it may become contaminated down stream and by testing it could have been prevented by having working backflow prevention devices.
As of Jan 2026 you can get your fine back (always check with spu there policies can change)
Shakopee Utilities backflow program states a penalty can be refunded to the customer account.
If an assembly is not tested and submitted within 30 days past the due date, it is
considered delinquent. A past due notice will be sent approximately 45 days after the due
date to the contact on file within The Compliance Engine.
For delinquent accounts, a one-time, annual testing penalty of $150 will be imposed on the
following month’s billing statement if test results are not submitted (or submitted test
results indicate a failed test) by the cut-off before the billing date (approximately ten days
before the scheduled billing date).
If the backflow preventer test fails, the owner must repair and/or replace the device within
30 days of the failed test results and a successful test submitted. No additional testing
penalties will be imposed.
At the same time, the owner’s irrigation system will be in a lock-out status. Lock-outs will
be conducted by SPU, with the majority being completed in the off-season. This will
prevent irrigation water usage in the following season without proper testing.
Upon request by the customer, the testing penalty may be refunded with a successful test
submission to The Compliance Engine within 60 days of receiving the penalty.
An alternative to annual testing is to have the sprinkler system locked out. You can request Shakopee Public Utilities to lock out your backflow system for free and your sprinkler system will not work and your lawn may die. Unless you drag some hoses around and water your lawn the old fun retro way.
