PROJECT PURPOSE and DESCRIPTION
·The Ogden Canyon siphon is the pipeline that is suspended between the canyon walls at the mouth of Ogden Canyon. The pipe is owned by the U.S. Bureau of Reclamation and operated by Pineview Water Systems. It has been in use since the summer of 1937, providing irrigation water for almost 80 years. It currently serves 10,000 customers in the Ogden area. ·The siphon is at the end of its operational life and needs to be replaced. A new pipe and support system with seismic upgrades will be installed. The new siphon will look very similar to the existing pipe.
Construction schedules are dependent on weather conditions, emergency situations or equipment/supply issues and are subject to change.
·Preparations are being made to remove the existing pipe. A protective highway cover has been built over SR-39 beneath the siphon and crews have begun construction of a set of towers that will facilitate the safe removal of the existing pipeline. ·The siphon will be drained and irrigation water will be shut off beginning October 1, 2015. Removal of parts of the existing pipe could begin as soon as October 2, 2015. ·The existing pipeline is scheduled to be removed by the end of November 2015 and construction of the new siphon will begin immediately thereafter. ·The new siphon is scheduled to be operational by early April 2016.
·Crews generally plan to work Monday through Friday, however, weekend work is likely as much of the work is weather-dependent. ·Traffic impacts could begin as early as Oct. 2, 2015 and are expected to continue through early April 2016. ·Lane closures and flagging operations should be expected on SR-39 at the mouth of the canyon throughout the project. Traffic will be stopped intermittently in both directions for up to 15-minute intervals to accommodate construction equipment access. Emergency access will be maintained. ·Full road closures will be periodically scheduled with advance notice to motorists. ·Drivers are encouraged to follow all signs and flaggers through the work zone to promote public safety.
Pineview Water has employed a project-dedicated public involvement team to keep the public informed and help address concerns throughout project construction. Residents with questions or concerns may contact Marcus Murdock:
