Oxnard Water Division Advanced Purification Facility

Mainstreet is the architectural design subconsultant to CH2M Hill on this facility that is considered the ‘corner-stone’ of the GREAT (Groundwater Recovery Enhancement and Treatment) program for the City of Oxnard Water Division.  The focus of the GREAT program is to use existing water resources more efficiently. The AWPF will provide the City with reclaimed water that can be used for landscape and agricultural irrigation, industrial process water, and groundwater recharge – the full build out phase will produce 25 million gallons per day of product water for reuse.

The overarching facility design represents cutting-edge process technology, while utilizing energy efficient, sustainable site and design strategies. The project includes a demonstration wetland accessible to the general public which incorporates an adjacent Visitors Center that will provide educational outreach for the GREAT program.  The entire facility will incorporate numerous “green” features such as recycled building materials, natural ventilation systems to reduce overall energy requirements, permeable paving, water conserving native plant material, and renewable energy photo voltaic solar power.

The AWPF campus is targeted to receive LEED Gold certification.
