APPENDIX F - IRRIGATION SYSTEM BACKGROUND AND PROJECTED

MAINTENANCE WORKLOAD DATA

BACKGROUND: Many of the irrigation systems on Hill Air Force Base require frequent maintenance. The majority of systems are comprised of PVC and poly piping however there are some galvanized systems on the installation. Systems are equipped with standard irrigation heads such as rotating gear driven, pop-up impact and spray heads. The majority of irrigated shrub and xeriscape areas are equipped with drip irrigation systems. Most systems are controlled automatically through electrical and/or battery operated controllers. Battery operated timers require inspection and battery replacement throughout the growing seasons. There are areas that require manual watering due to inability to control through automatic means.
