Document Description
City of Ontario Wellhead Treatment Project which proposes to install infrastructure to treat groundwater that has been impacted by perchlorate and deliver the treated water to the City of Ontario's municipal water supply. The project will be funded by State Proposition 50. Specifically, the project proposes to pump water from existing City Well No. 41, convey the water through a new pipeline, where it will be treated in a new treatment plant, and discharge the treated water into the City's existing water distribution system. Well No. 41 is located on Hellman Avenue, approximately 300 feet south of the intersection of 5th Street, in the northeastern portion of the City. Water extracted from Well No. 41 will travel approximately 1,300 feet in new conveyance pipeline, to be constructed within North Hellman Avenue, to the new treatment plant, which will be constructed on East 4th Street near the intersection of 4th Street and Hellman Avenue. The new pipeline will be constructed of 16-inch cement-mortar lined and coated steel. The new treatment plant will be constructed within a City-owned vacant parcel that is approximately 50 feet wide and 100 feet deep. Once treated, the water will be pumped into approximately 200 feet of new conveyance pipeline to be constructed in 4th Street, between the treatment plant and the City's existing 36-inch water distribution pipeline.
