City of Sunnyvale Water Pollution Control Plant

Since 1986, EOA has provided assistance to the City of Sunnyvale Water Pollution Control Plant (WPCP) on NPDES permit renewals, including Reasonable Potential Analyses, infeasibility studies, and negotiating permit requirements. EOA has also conducted special studies required by the plant's NPDES permit, including those associated with disinfection byproducts, chronic toxicity, ammonia, cyanide, and copper & nickel. EOA provides ongoing support to the City on plant operations and permit compliance, laboratory and pretreatment staff training, annual report preparation (e.g., NPDES, Biosolids, Pretreatment, Pollution Prevention, Recycled Water), and for the design and support of the WPCP's data management systems. EOA developed the framework for the City's Recycled Water Program and coordinated the design effort for most of its physical infrastructure, and prepared the Program's Title 22 Engineering Report. EOA has also provided support for the WPCP's master planning and capital projects, pilot projects, and participation in regional wastewater groups and programs.
