HB 1034: Modifications to Standards for Irrigation Equipment - Colorado

Rerevised → Final Act · 4 edits · Apr 16, 2026

MODERATE

This bill modifies environmental standards for irrigation equipment by simplifying requirements for spray sprinkler bodies and clarifying rules for irrigation controllers. It removes the mandate for spray sprinkler bodies to include check valves and shifts the certification requirement from meeting specific performance criteria to being certified under the federal WaterSense program. Additionally, it updates the legal definitions of key terms to align with these new compliance pathways.

Scope change

The bill maintains its scope covering irrigation controllers and spray sprinkler bodies sold as new in Colorado but alters the specific compliance standards applied to them.

REQUIREMENT

Eliminated the requirement that spray sprinkler bodies must include an internal check valve.

Changed the requirement for spray sprinkler bodies from meeting specific water efficiency criteria to simply being certified under the WaterSense program.

Updated the definition of 'Irrigation controller' to explicitly include soil moisture-based and weather-based controllers.

DEFINITION

Added specific definitions for 'Irrigation controller' and 'Spray sprinkler body' to clarify what products are covered.

MODERATE

The bill was amended to repeal the definition of 'check valve' and the specific environmental standard requiring them in spray sprinkler bodies, effectively removing the mandate for these components. The bill also removed the requirement for irrigation controllers to meet WaterSense standards for soil moisture-based systems, leaving only weather-based controllers subject to those efficiency rules. These changes reduce the regulatory burden on manufacturers by eliminating specific hardware and efficiency mandates for certain irrigation technologies.

Scope change

The bill's scope was narrowed by removing the applicability of the 'check valve' requirement to spray sprinkler bodies and by excluding soil moisture-based irrigation controllers from the WaterSense efficiency standards.

REQUIREMENT

Deleted the definition of 'check valve' and the requirement that spray sprinkler bodies must include an integral pressure regulator and a check valve.

Removed the requirement for soil moisture-based irrigation controllers to meet WaterSense program specifications.

Revised Section 3 to repeal only subsection (5)(h) regarding irrigation controllers, removing the deleted subsection (5)(k) regarding spray sprinkler bodies.

DEFINITION

Revised Section 1 to repeal only subsection (38) regarding irrigation controllers, removing the deleted subsection (10) for check valves.
