APEC economies visit innovative and energy-efficient irrigation systems in the Valparaíso, O’Higgins and Metropolitan regions

Delegates from Australia, China, the United States, the Philippines, Indonesia, Malaysia, Mexico, New Zealand, Peru, Thailand and Viet Nam visited floodgates with telemetry systems, an infiltration pilot project, a floating solar energy project and systems that use energy efficient components.

Santiago, Friday, July 26, 2019 Delegates from the APEC economies who are in Chile for the “Efficient and Sustainable Use of Water for Agriculture under the New Climate Scenarios” seminar spent two days in the countryside learning about water realities, progress and new technology applied to irrigation systems being developed in Chile.

As part of the activities organized by the National Irrigation Commission (Comisión Nacional de Riego, CNR), the representatives and international experts first went to the San Felipe province in the Valparaíso region to see a solar energy project whose panels float in an irrigation reservoir, thereby optimizing the surface area used. They then met with professionals from the Surveillance Board overseeing the first section of the Aconcagua river telemetry projects. They ended the visit with an initiative that makes efficient use of energy to irrigate table grapes.

CNR Executive Secretary Federico Errázuriz emphasized that, as Acting Agriculture Minister Alfonso Vargas has noted, in order to achieve truly competitive agriculture “the role of water-user organizations is crucial. Also continuing to coordinate between the public and private sectors will make it possible for us, as a country, to progress toward better management of the resource.”


On the second day, professionals from the Maipo Canal Society in the Metropolitan region shared what they called “very good results” regarding infiltration. These results are very important in terms of conducting aquifer recharge to different points throughout the country as a way to more efficiently use the available water in the current context of climate change.

Finally, the delegation comprised of CNR professionals and representatives from the economies of Australia, China, the United States, the Philippines, Indonesia, Malaysia, Mexico, New Zealand, Peru, Thailand and Viet Nam had the opportunity to visit Chimbarongo, in the O’Higgins region, where a solar powered irrigation system applies frequency inverters to electric pumps in order to improve energy efficiency.
