Van Gelder described what the plant will ultimately do for the community."We take it and we make clean water out of it, and that clean water is able to go back to the Boise River to improve that habitat and to make our community better."This first phase will allow for the addition of roughly 1,800 more housing units.

Van Gelder acknowledged the community's role in making it possible."A big thank you to our community for entrusting us with the funds to their utility rates."For O'Meara, the project is ultimately about Middleton's future."I just want the people of Middleton to know that we're putting this together for your children."The project is expected to take about three and a half years to complete before the new plant is up and running.For Canyon County happenings, news, and more join our Facebook Group: 2C Neighborhood News - Nampa, Caldwell, MiddletonThis story was initially reported by a journalist and has been, in part, converted to this platform with the assistance of AI.
