The pressurized irrigation will be winterized on September 30, 2022. After that date, the system will be turned off until April 15. The City asks that you leave the pressurized irrigation shut-off valve in the “open” position for a time to allow for proper drainage of the system.
Prior to the system being energized in the spring, you should make sure that you remembered to shut the individual shut-off valve. This will prevent your sprinkler components from being damaged during energization.
