Project Description

The project consists of replacing a 50-foot section of elevated wooden flume section on the Boardman Canal with a new steel substructure and half round metal flume that conveys raw water.

Project Location

The project is located near the City of Colfax, along Ben Taylor Road.

Project Schedule

• Begin Construction - Spring 2024
• End Construction - Fall 2024

Project Description

The project will consist of replacing the existing 4” steel distribution water main within Cable Road, Alta Power House Road, and Timber (red line). The main has experienced several breaks throughout the years and is at the end of its useful life. The pipe that goes from Brown Road south east through several properties to Alta Bonnynook Road may be replaced by installing a main in Alta Power House Road (yellow line). All existing services will be replaced and/or reconnected.

A new water main (green) will also be installed along Cable Road beginning at the intersection of Cable Road and Timber Lane going east connecting to the existing 10” distribution main at the east end of Cable Road. A pressure reducing station (PRS) will be included to connect two distinct pressure zones. The purpose of the new line is to increase the reliability of service by providing redundancy to a portion of the system.

About Project

The Lake Alta Dam project is a multi-year project to address regulation changes since the two Lake Alta dams were installed. Originally constructed for mining activities in the 1850's, the dams have been in continuous service ever since. This facility is an important component of PCWA's water delivery system, and this project will ensure lake levels, vegetation, and drainage comply with current regulatory requirements. See below for document links for this project.

Project Location

The Lake Alta Dam Project is located in the Town of Alta, near Bonny Nook Drive.

Construction Timeline

Consultants are currently gathering information on-site to be used to design improvements to the dams. Completion of design of improvements to the dams is anticipated in 2024. Any future construction work will proceed upon completion of design and regulatory approvals.

Latest Update

PCWA removed dead and dying trees in 2017 the vicinity of the dams to comply with direction from the California Division of Safety of Dams (DSOD). In winter of 2018/2019 PCWA collected bore samples from each of the dams. Additional samples collected from test pits and analyzed in 2021. Results from both sampling events will be used to support design of the necessary dam improvements..

Project Description

This project is replacing the existing 1.2 million gallons per day (MGD) Colfax water treatment plant (WTP) with a 2 MGD WTP (expandable to 3 MGD). The existing WTP is at the end of its operational life and requires full replacement. The new WTP will be constructed at the intersection of Rollins Lake Rd and Hwy 174 and will include additional capacity to accommodate future expansion of the water system and voluntary consolidations of smaller water purveyors in the region.
