Metro District Utilizes Smart Water Applications Technology to Manage Water Use
The Castle Pines North Metropolitan District's new Calsense Irrigation Flow Management System utilizes a centralized computer controlled irrigation system.
The system's flow meter sensors are able to detect abnormally high rates of water flow and are designed to shut down a main irrigation line within a few short minutes. The system is programmed to automatically send an "alert" message to the computer used by the parks and open space staff. The message provides the details of the issue and the exact location of the failure so that repairs can be made quickly.
Shortly after the system was brought online in 2008, a failure was detected in a main line break over a weekend and shut down the affected area, saving an estimated 168,600 gallons of water. That equates to the amount of water one family could use indoors for two years (based on 7,000 gallons a month). An added value to the system's design is that it will shutdown one zone when an emergency occurs, but continue the watering of other scheduled zones. Additional benefits of the system include water management reporting and water budgeting.
The Calsense system was purchased in 2007 with a $56,000 grant from the Colorado Water Conservation Board. Calsense is the leader in Smart Water Applications Technology (SWAT), a national partnership initiative created by the Irrigation Association to promote landscape water use efficiency through the application of state-of-the-art irrigation technologies. The Calsense system receives data from the Campbell Scientific Weather Station weather to determine weather conditions and is ET and soil moisture based.
