The San Diego County Water Authority Friday honored Japanese ceramics and electronics manufacturer Kyocera for reducing the annual water usage by its San Diego plant by nearly 20 percent since 2014. The Water Authority presented Kyocera with the Water Innovation & Efficiency Award at the Industrial Environmental Association’s 34th annual Environmental Conference at the San Diego Convention Center. The award is the agency’s inaugural recognition of San Diego companies that are mindful of their water usage. Kyocera has reduced its water usage by more than 6 million gallons since 2014, resulting in an annual reduction of $62,500 in water costs, according to the Water Authority.
