Martinez II-Upper Martinez Interconnect Line

This project will ensure that the outfall main between the Upper Martinez WWTP and the Martinez II WWTP can convey all the anticipated flow from the Upper Martinez service area to the Martinez II WWTP. The outfall main currently diverts some of the flow from Upper Martinez to Martinez II for treatment. Through CMOM activities it has been determined that the current outfall does not have the capacity to service the full demand of the Upper Martinez service area. Upon project completion, the line will convey all flow from the Upper Martinez and Martinez II service areas to the Martinez II WWTP. The River Authority will ultimately expand the Martinez II WWTP to treat all of this flow and decommission the Upper Martinez WWTP.
