Valley Water facility near Mountain View border will purify wastewater, use it to replenish groundwater

Original post made on Nov 10, 2023

Days after Palo Alto officials broke ground on a housing complex for homeless residents, they got an application for a very different development at an adjacent site: a wastewater purification plant near the Mountain View border.

A wastewater treatment plant will "enhance the natural state" of the Baylands?

Especially 'case this is very near the site (I think) that the MV Shoreline Community District/ MV City Council wanted to reserve for a North of 101 elementary school site/ MVWSD Trustees 'howling' about that idea. Good 4 them.

More recycled water / for MV ? good for MV.

The production of secondary sewer water in Palo Alto is already spread around to Stanford, Palo Alto and Mountain View for use in landscape irrigation. Some is already injected into the ground to replenish the local aquifer but that aquifer is doing well already. The remainder has to be discharged into the Bay.

This plan takes that water and pumps it miles to existing percolation ponds that replenish a different aquifer where Valley Water already replenishes it using its share of water from the state water project. The district also uses state supplied water to provide to customer water services via direct connections. The water the state currently puts onto ponds does not need to be purified by the percolation process.

The thing is though, that the Sunnyvale water treatment plant is closer and it also has secondary sewage treatment water available. They never explain why the shorter pipeline distance doesn't cause them to select Sunnyvale as the new source for the percolation ponds.
