The final steps of the SMD 3 Regional Sewer Project will occur this month. A Pipeline Inspection Gauge launching station, or PIG Launch, will be installed near Los Lagos on Auburn Folsom Road, and the existing WWTP will be demolished.
A public notice (PDF)for a hearing by the Central Valley Water Board to consider the rescission of the Waste Discharge Requirements (R5-2013-0076) has been posted. Public comments are due by 5 p.m. on March 15, 2015.
The public is invited to attend a ribbon-cutting event at the new pump station (abandoned WWTP site) on April 24th to celebrate the project’s completion.
Work will continue at the former wastewater treatment plant property this month with test-running the pump station and cleaning the digester. Sludge from the digester will be dewatered to the pump station and solids will be removed off-site for disposal. Once the digester is cleaned, the plant will be taken off-line and demolition of existing facilities will begin.
The newly constructed force main is complete and wastewater is now flowing to the City of Roseville Dry Creek Wastewater Treatment Plant. As a result, discharge into Miners Ravine has ceased, bringing the sewer district into compliance with State standards. However, there is still some work that needs to be completed to finalize decommissioning of the treatment plant.
Work at the wastewater treatment plant property will include:
Converting the sand filter to an equalization basin
Final grading and paving
Performing conformance tests of the pump station
Abandonment of those structures that will not be repurposed.
Work at Twin Rocks Road will include installing power and monitoring equipment. Short-term localized work along the shoulder of Auburn Folsom Road at Twin Rocks Road, and near Los Lagos, is not expected to impact traffic.
