Sewer Maintenance District 3 Regional Sewer Project

SMD 3 Regional Pipeline Vicinity Map

Project Description

Placer County is constructing a sewer pipeline and pump station to convey wastewater from Sewer Maintenance District 3 (SMD 3), located in the Horseshoe Bar area of Loomis, to the existing Sewer Maintenance District 2 (SMD 2) sewer collection system, located in Granite Bay, for treatment at the Dry Creek Wastewater Treatment Plant in Roseville and, ultimately, decommissioning the SMD 3 Wastewater Treatment Plant (WWTP). This project will bring the sewer district into compliance with State standards and will be accomplished with no increase to sewer rates.

The Board of Supervisors certified the environmental document for the project on November 27, 2012.

Project Location

The sewer pipeline will be installed along Auburn Folsom Road for approximately 2.5 miles, extending from the SMD 3 WWTP near Dick Cook Road to existing sewer pipelines near Twin Rocks Road.  The new pump station will be constructed on the existing SMD 3 WWTP site.

Project Schedule

November 2013 – August 2014: Pump Station Construction

November 2013 – June 2014: Pipeline Construction

August 2014 – December 2014: Plant Decommissioning

Monthly Project Updates

November 2014

Work will continue at the wastewater treatment plant this month with the installation of electrical equipment for the new pump station, construction of the equalization basin, application of the final lining of the storage tanks and wet well, and completion of the site’s final grading.  In addition, three new manholes will be installed at Twin Rocks Road and Auburn Folsom Road, and the connection will be made from the newly constructed pipeline to the existing SMD 2 wastewater collection system in preparation for the decommissioning of the wastewater treatment plant.

October 2014

Construction of the pump station will continue this month.  Work will include construction of the electrical building, utilities, and controls for pump station control buildings.  Work within the County’s road right-of-ways will include pressure testing the new pipeline, installing new manholes, flow meters and access vaults, and repaving roads.

September 2014

Construction of the pump station will continue this month.  Work will include final grading, testing of the wet well and emergency storage tanks, connection to the sewer force main, and constructing foundations for pump station control buildings.  In addition, piping and manholes will be installed at the intersection of Auburn Folsom and Twin Rocks Roads in order to tie the new pipeline into the existing line.

August 2014

Notice of Night Work

Construction of the pump station will continue this month and will include installation, testing and backfilling of the wet well and emergency storage tanks.

July 2014

With the completion of the pipeline installation in early June, and the installation of valves, repaving and striping along Auburn Folsom Road nearing completion, construction will continue at the pump station this month.  Work will include installation, testing and backfilling of the wet well and emergency storage tanks, connection to the pipeline on Auburn Folsom Road, and installation of piping for connection of wet well to existing treatment plant system.

June 2014

Pipeline installation work on Auburn Folsom Road will be completed by the first week of June.  Intermittent traffic control will occur during installation of valves along the line and delays should be anticipated at these times.  Construction of the pump station continues this month and will include rock excavation and transport, delivery of materials, including oversized concrete tanks, and tank installation.

May 2014

Pipeline installation work continues on Auburn Folsom Road where, as of April 30, approximately 9,300 feet (about 70% of the total route) has been installed from Twin Rocks Road to near Eden Rock Drive. Traffic control will continue to be in place Monday through Saturday; delays should be anticipated. Work that was anticipated for April at the SMD 3 plant site, just north of Dick Cook Road, is expected to begin this month. Work includes excavation and installation of the wet well, and trucking in sections of the concrete well on Auburn Folsom Road to the plant site.

April 2014

Pipeline installation work continues on Auburn Folsom Road where, as of March 28, approximately 6,400 feet (about 48% of the total route) has been installed from Twin Rocks Road to Moss Lane. Traffic control will continue to be in place Monday through Saturday; delays should be anticipated. Work activity at the SMD 3 plant site just north of Dick Cook Road is expected to increase this month with the excavation and installation of the wet well, which will include trucking in sections of the concrete well on Auburn Folsom Road to the plant site.

March 2014

Pipeline installation work continues on Auburn Folsom Road where, as of February 28, approximately 4,600 feet (about 1/3 of the total route) has been installed from Twin Rocks Road to just past Ardea Way.  Traffic control will continue to be in place Monday through Saturday; delays should be anticipated. Work activity at the SMD 3 plant site just north of Dick Cook Road is expected to increase this month.
