CLWA Groundwater Containment, Treatment, and Restoration Project

The Santa Clarita Valley Water Agency is implementing the Groundwater Containment, Treatment, and Restoration Project in Santa Clarita, California. Addendum 2 of the 2005 Mitigated Negative Declaration focuses on the Saugus 3 and 4 Equipping and V206/V207 Groundwater Treatment Improvements. Key infrastructure modifications include the installation of a new well wastewater discharge pump-to-waste pipeline that parallels an existing 18-inch PVC line and terminates at a new engineered outfall on the Santa Clara River bank, involving limited work within state jurisdictional areas. The project also involves abandoning a small pipeline segment in the Magic Mountain parking lot. Additional technical upgrades include minor site improvements at Wells 206 and 207, featuring new pumps, motors, and variable frequency drive controllers, as well as improvements to ion exchange vessels with provisions for future expansion at Wells S3 and S4. The scope further encompasses permanent equipment for Saugus Wells 3 and 4, the construction of a chloramination facility, and the installation of dual 24-inch pipelines connecting the facility to the existing well site, along with connections to existing 20-inch and 30-inch transmission and distribution pipelines. Design services and purchase orders for these works have been authorized through Resolution SCV-519.
