The San José-Santa Clara Regional Wastewater Facility (RWF) was constructed in 1956 as a primary water treatment plant. Secondary treatment facilities were constructed in 1964 in response to a growing population and economy along with state regulations. The RWF expanded to tertiary treatment in 1979 to meet Clean Water Act regulations. A wet weather headworks facility was commissioned in 2008, and in 2011 the gaseous chlorine/sulfur dioxide system for disinfection was converted to a sodium hypochlorite/sodium bisulfate system in 2011 (RWF 2015). The RWF launched a Capital Improvement Program (CIP) in 2014, identifying 33 capital projects. The Facility Wide Water Systems package (package PF-06) in the CIP served as the inspiration of the Regional Wastewater Facility Systems Design project.

Package PF-06 states that the RWF has four water systems in need of rehabilitation and upgrade: 1W (potable water), 2W (groundwater), 3W (process water) and 4W (fire protection water). Due to age, condition, and change in water demands over time, the RWF requested an updated hydraulic model and assessment of current and future water demands for a proper redesign of each system. The Hydraulic Engineering and Design (HEAD) team has decided to redesign the RWF’s 1W and 2W systems for this capstone project.
