The Ontario Water Treatment Plant supplies the City and the Snake River Correctional Institute with high quality potable water. The treatment plant is a conventional surface water treatment plant with mixed media filters, adsorption clarifiers and flocculation/clarification basins. The main treatment plant can treat up to six million gallons of water per day, with an additional four million gallons per day treated through the new plant built in 2005-2006. Snake River water is blended with a series of shallow surface water influenced groundwater sources (wells). Treatment is required for iron and manganese reduction, sediment/color removal, taste/odor control, and chlorine disinfection/filtration for microscopic organism destruction and removal. Located at: 1900 SE 5th Avenue |

Backflow Testing
The City of Ontario has a Cross-Connection Program which is administered by the Operations Division. Oregon Health Services has established rules that require the City to protect its water system, which is accomplished by requiring that all underground sprinklers attached to the City's water main have a backflow device installed. This device prevents any non-potable water source within a citizen's property from entering into and contaminating the community drinking water supply. The Operations Division monitors the identification and testing of backflow devices in the City.
