From Colorado Water Wise (Ruth Quade):
Colorado is the first state to proclaim July Smart Irrigation Month thanks to an effort lead by CPS Distributers, Inc., an irrigation distributer with 11 branches in Colorado and Wyoming.
The Irrigation Association first launched Smart Irrigation Month in 2005 and it is gaining traction as stakeholders recognize the impact of efficient irrigation in July and year round. July is typically a peak month for water consumption and warrants attention. Water treatment plants must be designed to handle peak production. By shaving peaks, expensive treatment plant upgrades can be delayed or avoided.
