It alerts users to potential problems and helps address areas of optimization. Rose said that customers typically see between a 15 and 30 percent reduction in water use, which is more valuable given in big cities. He said the system pays for itself in 18 to 24 months. Apana has customers such as Costco and MGM Resorts International in more than 600 cities globally, but Rose said the opportunity remains large. He noted that less than 1 percent of commercial, industrial, and institutional buildings in the U.S. have any kind of water management system. “This type of solution has not readily been available, because without some sort of IoT solution connected to analytics and reporting, it’s nearly impossible to do,” he noted. Total funding to date for Apana is $15.5 million. The company, which its seed round more than two years ago, employs 16 employees.
