The Palmdale Water Treatment Plant is located south of the City of Palmdale within the San Andreas Fault Zone. In addition, there is a 0.5 megawatt hydroelectric plant.

Earth Systems provide a geotechnical engineering investigation and geologic hazards study for this project. Site conditions included shallow bedrock, numerous fault traces, and alluvial fill. Subsurface conditions were evaluated by drilling and extensive trenching of the site. Following completion of the field and laboratory work Earth Systems developed mitigation measures to accommodate the site conditions. The project was constructed in two phases and currently operates with a capacity of 40 million gallons of water per day that is treated for municipal use.

Following initial construction, 1 megawatt wind turbine and adjacent 6 million clearwell tank were constructed. Earth Systems produced geotechnical consulting services for those projects as well.
