Colorado changes rules for irrigation equipment

Colorado removes nonagricultural irrigation controllers from this law’s product standards, affecting businesses selling or leasing new controllers. It repeals the WaterSense requirements for weather-based and soil moisture-based controllers that began January 1, 2026. Spray sprinkler bodies no longer need a check valve. They must have WaterSense certification instead of simply meeting WaterSense performance criteria. These changes apply to conduct starting on the effective date: 12:01 a.m., 90 days after the legislature’s final adjournment. That date is August 12, 2026, if adjournment occurs May 13, 2026. A timely referendum petition delays the challenged changes unless voters approve them at the November 2026 general election. In that case, they take effect when the governor officially declares the vote. The law creates no direct household payment.
