Capital Improvement Project


Oakmont Treatment Plant Sewer Trunk Relocation

Estimated Construction Schedule: Slated to begin June, 2018 and is anticipated to be completed October, 2018.
Construction Contract Amount: Pending
Project ID #: 1805
Description: This project will install a new sewer trunk line in order to by-pass the Oakmont Treatment Plant. The existing plant by-pass line has several elevation changes and causes solids to build-up, reducing flow, requiring local operation crews to conduct routine cleaning and flushing of the sewer trunk. A new bypass trunk line would greatly reduce maintenance costs and the possibility of sanitary sewer overflows.

Clarification to Advanced Notice Letter - March 22, 2017: The pedestrian foot bridge to the east of the Oakmont Treatment Plant will remain in place and is not included in this project. The steel ribbed bridge referred to in the advanced notice letter is located on the northwest corner of the Oakmont Treatment Plant and the sole use of this structure is to support the existing sewer trunk as it crosses Oakmont Creek. As part of this project the steel ribbed bridge will be removed and the sewer trunk will be relocated under the creek to better protect the pipe. See Exhibit 1.
