House Bill 23-1161 established
environmental standards

an environmental standard
for irrigation controllers
and spray sprinkler bodies
that are sold or leased in the state on and after January 1, 2026
, and are not specifically excluded from the federal WaterSense program (program)
. The bill repeals the environmental standard for irrigation controllers.
The bill also modifies the environmental standard for spray sprinkler bodies to:
No longer require that spray sprinkler bodies include a check valve; and
Require that spray sprinkler bodies are certified to the program, rather than requiring that spray sprinkler bodies meet the water efficiency and performance criteria of the program.
