TWIN FALLS — The city is moving forward with a study to determine what’s causing the foul odors along a sewer pipeline in northwest Twin Falls — and how the city can control it.
On Monday, the City Council awarded a contract with Murray, Smith & Associates in Boise to study the 5-mile sewer pipeline corridor along Grandview Drive and in Rock Creek Canyon.
“We’re trying to determine what the odors are caused from and where they are located,” Assistant City Engineer Troy Vitek said.
Hydrogen sulfide produced from sewage is also a concern with corrosion.
Twin Falls resident Dennis Crawford said that in his discussions with city staff, “They’ve been concerned that they would have manholes actually fall from truck traffic driving over them.”
He believes a project that’s underway to upgrade a collector line in Rock Creek Canyon will help tremendously. Crawford owns a business that assists dairies in the area with odor control. He asked to be involved in the city’s odor control project.
“Those who live on the northwest side of town used to call the corner of Grandview and Pole Line ‘poop corner,’” he said.
While it’s gotten better in recent years, on days with more loads of potato and cheese processing waste, it gets worse.
Also, “The hotter it is, the more odors there are,“ Vitek said.
The city will pay the engineering firm $39,908 to determine what odor-reducing measures can be taken. The study is funded through a bond previously passed by voters.
Also at the meeting, the Council:
Met two new narcotics-detecting dogs that will be working with Twin Falls Police and Twin Falls County Sheriff’s Office. The golden retriever and chocolate Labrador were donated by Blue Lakes Rotary Club and Ken Pavlick.
Adopted an ordinance zoning 2016 Addison Ave. E. for professional offices.
