Santa Paula Water Recycling Facility

Santa Paula, CA

In our view, one of the most compelling aspects of the PERC Water approach is their Conceptual Design Report (CDR™). Because of their track record of DBO and DBOF project delivery, they are able to offer a guaranteed project cost to potential municipal partners upon completion of 30% design and delivery of the CDR™ (at a fraction of the cost required for 100% design).

PERC Water and its financial team member, Alinda Capital Partners, formed Santa Paula Water, LLC, which was contracted to Design/Build/Operate/Finance (DBOF) a 3.4 MGD (expandable to 4.2 MGD) PERC Water ASP® MBR for the City of Santa Paula, California. The project is the first of its type under California Government Code Section 5956-5956.10, allowing for a DBOF delivery method. Santa Paula Water, LLC, was awarded the DBOF contract in May 2008, broke ground in July 2008, and construction was completed in December 2009. The new Facility has been treating 100% of the City’s wastewater beginning May 13, 2010, seven months earlier than the compliance date issued by the Regional Board. PERC Water utilized more than 85% local labor for the construction (more than 141,000 total man hours) and invested more than $4.5 million in the local economy (not including the local sales tax revenue).

PERC Water operated the new facility under a 30-year asset management service agreement. The facility utilizes advanced treatment process technologies incorporating MBR (membrane bio-reactors), aerobic sludge digestion, and UV (ultraviolet) disinfection that produces CA Title 22 compliant effluent. The facility is completely enclosed for maximum odor control as well as esthetic appeal.

PERC Water’s unique design utilizes common wall construction to help achieve a small footprint allowing the City to save valuable land for alternate use. The design has approximately 11,600 square feet of above tank buildings that include 3,100 square feet of finished office space.

PERC Water and Alinda were presented the Global Water Awards 2009 “Water Deal of the Year” Award of Distinction for their utilization of public-private partnerships in their contract to design, build, operate and finance the Santa Paula Water Recycling Facility. Global Water Intelligence stated the decision made by the City of Santa Paula to use private-sector funding demonstrates a “bold new direction in the financing of US water infrastructure” and described the deal as a “ground-breaking transaction, which can be emulated across the United States.” PERC Water’s scope of service for operations and maintenance included all labor to operate and maintain the facility, regulatory compliance, chemical and power consumption, capital improvements and air quality compliance.
