The scoping period for the Pasadena Groundwater Storage Program – a project led by Pasadena Water and Power (PWP) - began on November 28, 2006 with the release of the Notice of Preparation (NOP). A public scoping meeting was held on December 13, 2006 at the Pasadena Senior Center. An Environmental Impact Report was prepared and is now available for viewing

The proposed project is a conjunctive use program between Metropolitan Water District of Southern California (MWD), PWP and Foothill Municipal Water District (FMWD) to improve the reliability of water supply to the City of Pasadena and surrounding water agencies and reduce the region’s dependence on imported MWD water during an emergency or drought conditions. Capital improvements to be constructed under the proposed project consist of five major components: (1) construction of three ASR wells, (2) construction of a groundwater nitrate treatment facility, (3) construction of a new or upgraded interconnection between the PWP and FMWD water distribution systems, (4) construction of a groundwater perchlorate treatment facility, and (5) construction of a collector pipeline between seven existing wells in the PWP service area.
