Over the next two years, Santa Clarita, Calif. will roll out a massive irrigation system over 700 acres that's expected to save more than 180 million gallons of water a year. The project is touted as the world's largest smart water management implementation.
The city's previous irrigation system required manual adjustments whenever the local weather conditions changed. This week, the city announced its partnership with HydroPoint, the manufacturer of the WeatherTRAK Internet-enabled, centralized irrigation controllers that will replace outdated irrigation timers in Santa Clarita's 40 landscape maintenance districts, including parks, medians and streetscapes.
The new controllers, according to the manufacturer, can adjust watering schedules automatically while eliminating the costs of weather station maintenance, telephone lines, wireless transmitters and additional equipment. Paid for by landscape maintenance district funds, the implementation will cost about $1.5 million for the controllers, installation, setup, training and regular reports, the project managers said. None of the city's general fund goes toward the project, officials said. With the new system, the city hopes to reduce annual water consumption and, as a result, costs by 20 to 40 percent.
"This is what we considered our lowest-hanging fruit with the most significant and quickest return," said Jason La Riva, landscape maintenance specialist for Santa Clarita. "Ultimately the driving force behind this program was to reduce our water consumption. If we can knock out 20 to 40 percent right off the bat, this is a real significant contribution to our community and water conservation efforts statewide."
