Caldwell Municipal Irrigation Dist.

The Caldwell Municipal Irrigation Dist. was established in 2005 and is operated by a staff of water delivery professionals under the guidance of the public works director and the water superintendent. It is the responsibility of the irrigation department to operate and maintain all city pressurized irrigation systems and take every possible precaution to ensure the safety and health of the public and comply with applicable state and federal law (Idaho Statutes Chapter 50 Title 18) relevant to the delivery of irrigation water.


The Caldwell Municipal Irrigation District would like to remind all its patrons that irrigation bills are mailed out once a year in February and are due April 1st each year.

We anticipate receiving  irrigation water to our pump stations around April 15th. Customers may experience low pressure or water being on and off for the first couple of weeks while maintenance crews test lines. CMID will shut the lines off if repairs need to be made, so patience is requested. All CMID customers are asked to abide to our odd-even watering schedule. Customers need to check the programming of their sprinkler control box to assure they are not over watering. Customers who need help programming the sprinkler control box need to contact a lawn professional. Customers are encouraged to install their own shut off valve to control sprinkler lines and not operate the city valve which is for emergency use only. Report irrigation leaks to 208-455-3070 opt.2 or After Hours to 208-250-1638.
