The city's private water quality facility maintenance program includes inspections of all residential, commercial and industrial stormwater water quality facilities maintained by private property owners. These facilities are constructed to protect precious water resources by removing pollution from stormwater runoff before it enters drinking water sources, as well as Johnson Creek, Kellogg Creek Willamette River and other local streams. The program intends to educate property owners about how these facilities function and to ensure that facilities are maintained and operated properly.
