Centralized Irrigation Control System

CICS is expected to provide a 30-50% reduction in irrigation water use.

The CICS is comprised of a central computer, local irrigation controllers, and a radio telemetry system for communication. The local controllers control either a single large building's or multiple small buildings' irrigation equipment. Where water meters are installed, the controller "learns" the typical flow rate and will alarm if a low/no flow situation or a high flow/mainline break situation occurs. In addition, a short circuit in the system will send an alarm. All alarms are sent to the central computer daily and are acted upon immediately. The central computer can send out site wide commands, gather data from individual controllers, and stores irrigation controller data (water use, alarms, etc.).

The CICS has decreased troubleshooting times, decreased required time spent on preventative maintenance, and allowed for better tracking of water consumption, system alarms (low/no flow, short circuit, main line breaks), and implementation of proper irrigation schedules. Although the total consumption for irrigation is small compared to the entire Sandia/New Mexico consumption, landscape irrigation is one of the most visible uses of water and potential waste. Also, a better controlled irrigation system will also minimize maintenance needs and chemical costs, all while maintaining a beautiful site. Once all CICS equipment is installed and programmed, an anticipated 30-50% reduction is expected in irrigation water consumption. See the History for the status of CICS.
