The city of Ontario recently gave an update on the project to build its own waste water treatment plant. According to RichlandSource.com, the plant would be built at the west Nussbaum Parkway inside of the Ontario Industrial Park on 11 acres of city own land. The plant will only take up about 3 acres and will see annual saving of around $1 million. The facility could be up and running sometime in 2026, but an exact date has not yet been announced.
