Public Works Water Management System

619 answers for local water conservation

With four years of drought conditions and water management mandates the City of Rancho Cucamonga has been successfully managing these challenges with the development and implementation of technology. Over the last 30 years, Public Works has worked diligently to design and implement a Calsense Irrigation Water Management System, which efficiently delivers irrigation throughout the city.

The City's eight Landscape Maintenance Districts benefit from the use of this technology to minimize their water utility expenses. This is achieved by using 619 technologically advanced Calsense irrigation "smart" controllers in all parks, parkways, and paseos. This system saves water by sharing weather information to all controllers collected from two different Evapotranspiration gages located in the City and automatically adjusting water times as the weather changes. The use of the master valves and flow meters connected to these controllers allows the irrigation systems to shut down in the event of a mainline break preventing water loss, property damage, and traffic hazards.

Two central computers with Calsense software installed at the City yard allows Water Management staff to manually send "no water days" commands to all controllers prior to rainfall, saving additional days of unnecessary irrigation. Water use reports, alert history, and other valuable information can be easily obtained from these central controllers. Finally, the Calsense Irrigation Water Management System has a "Direct Access" feature which allows City staff to view a controller screen in live time.

This functionality allows staff to verify mainline breaks and secure the master valve with a few keystrokes from the Central controller. In an era where efficient and effective water use management is necessary to successfully manage the City's eight landscape maintenance districts, the City of Rancho Cucamonga's Public Works Services department has met that challenge with the Calsense Irrigation Water Management System.
