Irrigation Season:  We anticipate receiving irrigation water to our pump stations & turning them ON after April 15th, and the season will END around October 1st - 15th. Please note that the more people who try to use the water at one time will reduce the pressure in the lines. As a reminder please adhere to our recommended watering schedule – odd/even day based on your address.

During the season, PI stations may be down due to mechanical and/or electrical issues, leaks and other unforeseen problems. This is normal. If this occurs we will try to keep you updated on the City’s Facebook page, the Nextdoor app, & City’s Irrigation website.

Update as of 07-10-20 @ 8:00am: All PI stations are on. 


Thank you,

Caldwell Municipal Irrigation Department
