Sewage Odor in Ontario
April 26, 2019


The City of Ontario Wastewater Treatment Plant is experiencing an odor due to a biological upset in the system. A biological overload in the system has caused an unpleasant odor from the lagoon system. Staff members are working to achieve equilibrium in the system.

This situation does not pose any danger to the system or to any persons; however, we apologize for the unpleasant odor and hope that you will bear with us as the natural process occurs to reduce the odor.

For questions, please contact the Public Works Office at (541) 889-8572.
