Upper Salinas River Basin Conjunctive Use Project 

(US-CUP) Overview 

 The Templeton Community Services District is developing a new, drought resistant water supply to meet seasonal and projected annual demands. The project, called the Upper Salinas River Basin Conjunctive Use Project (US-CUP) will capture existing wastewater flows that are currently being discharged outside of the Atascadero Basin, and return these east side area wastewater flows back to the Meadowbrook Wastewater Treatment Plant (MWWTP) for treatment, discharge and subsequent retrieval of water from District wells downstream.

As shown on the map, the District wastewater service area is bisected by Highway 101 into two distinct wastewater areas. The west side area flows are treated at TCSD Meadowbrook Wastewater Treatment Plant (MWWTP) where it undergoes secondary treatment and is discharged into infiltration ponds, percolates into the underflow of the Salinas River and subsequently retrieved by TCSD wells downstream. However, the east side area flows are sent to the Paso Robles WWTP for treatment and disposal where the water is no longer available for retrieval by the District. The US CUP facilities will redirect all of the wastewater generated in the east side area to the MWWTP, thereby increasing the supply by an additional 242 acre-feet per year (AFY).

The infrastructure improvements needed are the construction of two new lift stations and approximately 16,200 linear feet of sewer pipeline to capture and redirect East Side flows to the west side collection system. From there, additional upgrades needed to convey the flows to the MWWTP include upgrading the West side Lift Station, and finally upgrading the MWWTP headworks at the Meadowbrook Wastewater Treatment Plant (MWWTP). These project components are together named the Upper Salinas River Basin Water Conjunctive Use Project (US CUP).

The East Side Force Main and Lift Stations (ESFM) Project components make up the bulk of the needed infrastructure improvements.  After several years of effort spent obtaining environmental clearances, easements, various permits, and assembling financing, the project is under construction. The construction contract was awarded to Specialty Construction Inc on February 22, 2018 and construction is anticipated to be complete by the end of the year.
