. . 1996 Water Conservation and Water Use Efficiency- Block Grant Program This proposal is being made for water conservation upgrades at Smokey Hill Group Picnic Area, at Cherry Creek State Park. These measures would encompass an investment of the "Grant Monies", to increase water efficiency, in control of resources for scheduling purposes, tracking the water usage, system maint~nance, reduction of run off and reduce water loss below the root zone, Following is how the water conservation measures will be specifically addressed. \, Universal Eicon Remote, for water usage review and planning purposes 2, Flow Sensor, to monitor flow and calculate loss 3, Rain Master Hawk Controller, to incorporate specific cycle, scheduling and remain consistent with other equipment at equivalent sites, 4, Master Control Valve (Buckner Brass), this unit is utilized to provide immediate system shutdown should leaks occur at main line or lateral areas, 5, Hunter Industries 1-25 Rotor Heads, to provide water savings and economical. Efficient water conservation depends upon a systems ability to function at an efficiency of at least 70%, As a system ages, that can drop the efficiency dramatically below 50%, Most systems have a design life to 15 years average, At Cherry Creek State Park, these systems are at the 50% range or below currently, The Rain Bird 47 series, rotor pop up heads, now average from $167,00 to $239.00 each, Also the efficiency ratings are based upon heavy watering application rates in soils that have a high infiltration rates. At the sites, at Cherry Creek State Park, the soils vary widely from sandy to clay, therefore lower applications rates with additional cycles would benefit runoff control. The choice of newer technology irrigation heads with improved precipatationinches per hour rates would be ideal, One such head would be the 1-25 industrial-strength head by Hunter
