[ARCHIVED] Downtown Pipeline Maintenance to Create Additional Traffic Restrictions


Contractors with the City of Twin Falls will be cleaning and rehabilitating wastewater pipelines in Downtown Twin Falls beginning Friday, May 10 through Friday, June 28.

Work will take place in alleyways adjacent to Main Avenue between Fairfield Street and Liberty Street, and along intersecting roads with those alleyways. Additionally, work will take place along Shoshone Street between Fifth Avenue South and Sixth Avenue South.

The construction process – known as Cured-in-Place Piping – will install a new sewer pipe inside the older deteriorated sewer pipe, greatly improving wastewater service in the downtown area. The new sewer pipe will be installed through existing sewer manholes, so the process does not often require digging the roadway/alleyway unless a broken pipe is located.

Additional traffic controls will be in place so workers can safely access sewer manholes and space for the new sewer pipe to be installed, traffic control will be used, and an alleyway block will be closed for up to a day or two during the various phases of the work.  Additionally, some cross streets or traffic lanes will also be closed such as Idaho Street during sewer work on nearby adjacent blocks.

The City of Twin Falls has contracted with Insituform to complete the work, and J-U-B Engineers will be providing project oversight. Insituform and its subcontractor Pro Pipe, will coordinate with downtown property owners who may be affected.
