Zone 7 has taken big steps in both reducing energy costs and helping the environment.

In 2011, the Agency completed a solar power installation at its Del Valle Water Treatment Plant. More recently, in 2013, it worked to increase its alternative power and renewable energy use portfolio through a Power and Water Resources Pooling Authority (PWRPA) project at the Patterson Pass Water Treatment Plant. The next planned PWRPA project is at the Mocho Groundwater Demineralization Plant and two nearby wells.

"This is a win-win for our water ratepayers and for the environment," Zone 7 board President John Greci said during a solar project open house celebration on June 22, 2011.

In a partnership between Zone 7 and Borrego Solar Systems Inc., Borrego -- a leading designer and installer of grid-tied solar electric power systems -- designed and built, and now operates and maintains, the 348-kilowatt photovolatic system at its own expense. Zone 7 will buy all of the electricity the facility produces at a fixed rate. 

The solar panels will produce about a third of the energy Zone 7 uses in water-treatment and other operations at the Del Valle plant. Zone 7's estimated reduction in energy costs is expected to exceed $800,000 over the 20-year term of the agreement. In addition, by reducing reliance on conventional power plants that burn fossil fuels, the project will cut annual greenhouse gas emissions that contribute to global climate change.
