Modifications to Standards for Irrigation Equipment
Summary
House Bill 26-1034 modifies Colorado’s environmental efficiency standards for certain irrigation equipment sold or leased in the state. The bill repeals the existing state standard for irrigation controllers that had been scheduled to take effect on January 1, 2026, and removes irrigation controllers from the list of products covered by the relevant state product-efficiency law. It also changes the standard for spray sprinkler bodies by eliminating the requirement that they include a check valve and by shifting the compliance requirement from meeting WaterSense water-efficiency and performance criteria to being certified to the WaterSense program.
In practical terms, the bill narrows state regulation of irrigation controllers and relaxes one component requirement for spray sprinkler bodies, while still keeping a WaterSense-based certification framework for those sprinkler bodies. The measure affects manufacturers, distributors, retailers, and lessors of irrigation equipment in Colorado, as well as purchasers of irrigation products, by reducing some state-specific compliance obligations before the 2026 effective date. It also updates statutory definitions and scope provisions in Colorado’s product-efficiency article to reflect the removal of irrigation controllers from coverage.
The overall sentiment around the bill appears broadly favorable and low-conflict. It advanced through both chambers with strong committee support and large floor majorities, and the Senate Agriculture & Natural Resources Committee recommended it for the consent calendar, suggesting limited controversy. The voting history shows only one dissenting vote in the House third reading and otherwise unanimous or near-unanimous support.
The main point of contention, to the extent one exists, is the policy choice to scale back environmental and efficiency requirements for irrigation equipment. Supporters likely viewed the changes as a simplification of standards and a reduction in unnecessary regulatory burden, while any opposition would likely come from those favoring stronger water-conservation requirements, especially in a state where irrigation and water use are significant policy concerns. However, the recorded votes indicate that any disagreement was modest and did not materially slow the bill’s progress.
Impact
The bill amends Colorado Revised Statutes title 6, article 7.5, by repealing the definition and applicability provisions for irrigation controllers and deleting the existing performance standard for those products. It also revises the standard for spray sprinkler bodies so that they no longer must include a check valve and must be certified to the WaterSense program rather than independently meeting WaterSense efficiency and performance criteria. These changes affect product manufacturers, sellers, lessors, and consumers by reducing state-level compliance requirements for certain irrigation equipment beginning on the bill’s effective date.
Sentiment
The bill appears to have received generally positive and bipartisan support. It passed committee and floor votes overwhelmingly in both chambers, including a consent-calendar recommendation in the Senate, which typically indicates limited opposition. The near-unanimous votes suggest the measure was viewed as a technical or targeted regulatory adjustment rather than a highly divisive policy change.
Contention
The primary substantive tension is between reducing regulatory requirements for irrigation equipment and maintaining water-efficiency standards. Critics of the bill would likely object to repealing the irrigation controller standard and removing the check valve requirement for spray sprinkler bodies, arguing that these changes could weaken conservation and performance protections. Supporters, by contrast, likely favored aligning state requirements more closely with WaterSense certification and easing compliance burdens for industry. The sparse recorded opposition suggests these concerns were present but not strongly contested in the legislative process.
