Document Description
Zone 7 owns and operates ten (10) different groundwater producing well sites around the Tri-Valley area that range in age from ten (10) to fifty (50) years old. As facilities age, equipment must be replaced to ensure reliable operation. Some equipment also fails as it ages and must be replaced in order for the facility to operate again.
The subject project includes seven (7) different well and treatment sites where electrical equipment has either failed or has reached the end of its useful life. Existing electrical switchgear at the Mocho 2, Hopyard 6, Hopyard 9 and Stoneridge well sites is scheduled to be replaced with new electrical gear to allow for continued reliable operation. Variable frequency drives (VFD) at the Chain of Lakes (COL) well 1 and well 2 sites and the Mocho Groundwater Demineralization Plant (MGDP) are scheduled to be replaced due to failures of some of the VFDs and reaching the end of their useful lives on other VFDs. In total, there will be seven (7) VFDs replaced at the three (3) sites.
The seven (7) different facility sites contained in this project are all located within the City of Pleasanton. The Mocho 2 well site is on Santa Rita Rd. approximately 1,100 feet south of the intersection of Santa Rita Rd. and Stoneridge Dr. in the City of Pleasanton. The Hopyard 6 well is located at 5997 Parkside Dr. in the City of Pleasanton. The Hopyard 9 well is located approximately 1,200 feet east of Hopyard Rd. along the north bank of the Pleasanton Canal in the City of Pleasanton. The Stoneridge well site is located at 3750 Stoneridge Dr. in the City of Pleasanton. The COL 1 & 2 well sites are located at 2655 El Charro Rd. in the City of Pleasanton. The MGDP facility is located at 5215 Stoneridge Dr. in the City of Pleasanton. All of the work is contained within these existing Zone 7 facilities.
The Project work is anticipated to take place between February 2023 and April 2024.
Due to the project being replacement of existing equipment at all of the included sites, there is not expected to be any new elements as a part of the project, nor will there be any new public nuisances that result from the project.
