Pleasanton Weekly –
Two major studies that directly effect the quality and cost of the Tri-Valley’s drinking water got underway this month.
In Sacramento, the Newsom Administration formally announced it will pursue a single large tunnel to move Sacramento River water south from Sacramento to the Banks pumping station near Tracy. The single-tunnel approach differs from the twin tunnels that former Gov. Jerry Brown pushed for the eight years of his term and could not get moving forward. Prior Gov. Arnold Schwarzenegger had re-initiated Delta studies during his terms.
Meanwhile the Livermore Valley’s wholesale water and flood control agency, Zone 7, launched a $1 million study on improving the valley’s water supply in partnership with the cities of Pleasanton and Livermore and the Dublin San Ramon Services District. The agencies will split the cost. The analysis will include the Delta Conveyance as well as treating and re-using sewage effluent, the expansion of Los Vaqueros Reservoir south of Brentwood, and a potential desalination plant in the west Delta.
It will also consider participation in the proposed Sites Reservoir, which would be off-stream near Maxwell with water pumped in during high winter flows and then released in place of cold water from Lake Shasta during the warmer months. That’s how the giant San Luis Reservoir operates south of the Delta near Los Banos.
