City of Twin Falls Identifies and Mitigates Odor Issue on Kimberly Road


By Paul Johnson

Twin Falls, Idaho ( KMVT-TV / KTWT-TV ) - The City of Twin Falls Wastewater and Engineering departments, responding to odor complaints on Kimberly Road and Hankins Road, have identified and is mitigating the cause of a strong odor. The cause of the odor has was determined to be caused by a closed valve on an anaerobic digester that is commonly referred to as UASB.
The valve has since been opened and the odor is expected to be almost fully reduced within two weeks.
The City of Twin Falls began receiving complaints in early December of a strong odor and immediately started work to identify the cause of the odor. City workers monitored the odor twice a day on nearby wastewater collection lines to try and identify the source. The odor was not continuous and appeared to be isolated to an area near the intersection of Kimberly Road and Hankins Road.
To help mitigate any future odor issues in southeast Twin Falls, the City is designing odor control facilities for two downstream locations. The City is also placing carbon filters at various locations along the collection line to reduce downstream odors.
