SANTA CLARA VALLEY WATER DISTRICT

Filanc completed the construction of an advanced water purification facility that treats secondary effluent from the San Jose/Santa Clara Water Pollution Control Plant (SJ/SC WPCP) to produce high-purity recycled water utilizing microfiltration (MF), reverse osmosis (RO), post-RO water stabilization, and ultraviolet (UV) disinfection. The high-purity water from the Silicon Valley Advanced Water Purification Center (SVAWPC) is blended with filtered tertiary effluent from SJ/SC WPCP and feeds into the SVAWPC system via the SVAWPC Transmission Pump Station (TPS). However, the product water from this plant can, in the future, be utilized for potable uses should that become a local need.

Filanc constructed facilities that included the influent (MF vertical feed) pump station, 32,000 square foot MF/RO/UV process building, 2.25 million gallon stainless steel product water and 220,000 gallon inter-process storage tanks, various chemical storage and chemical feed facilities, 10 million gallon per day (MGD) RO transfer pump station and filter facility, decarbonation towers and transfer pump station, and a waste equalization pump station. The facility also employed a series of pipelines to transport secondary effluent from the SJ/SC WPCP to the facility and returned advanced treated effluent back to the SJ/SC WPCP.

Design and Construction Management Techniques

Filanc is a firm proponent of formal partnering and has made it a requirement on all of its major projects for nearly two decades. Formal partnering was conducted for the Silicon Valley Advanced Water Purification Center project to ensure that the project goals were met and that Owner expectations were exceeded. Stakeholders included the Owner, the Owner’s engineer, and the City of San Jose. A partnering charter was established to define levels of excellent performance and outcomes that all stakeholders were committed to achieve.

During construction Filanc was able to address all challenges that arose which included collaboration and redesign of the pipe supports within the pipe trenches of the process building, as the pipe supports shown in the drawings would not have worked properly. Filanc embedded strut in the walls that also allowed the Owner space for future use and supports for small pipes and conduits. The team also had to address the oversight in coordination between new and existing work and redesigned the existing infrastructure to incorporate the new construction.

Despite the numerous challenges that typically accompany a project of this size and complexity, the project was delivered with high quality with a high degree of cooperation and collaboration.

SCHEDULE

Construction of the Silicon Valley Advanced Water Purification Center presented a variety of challenges that required the District to approve a number of change orders and schedule extensions. It is our understanding that the facility design available at the time of bidding, was the end product of an extended design process that saw multiple changes in the size and scope of the plant including the location of operations. Consequently a number of inconsistencies became apparent during construction. One notable example were changes in the design and installation requirements of the pre-selected microfiltration OEM supplier. In addition, during construction the District changed power providers to the plant which caused a number of issues for both the design and construction teams.

Filanc also experienced a number of complications with the plants’ two stainless steel process and product water tanks. Shortly after bid submittal, our listed tank manufacturer reneged on its bid causing both financial and schedule issues. Later in the project, microbial degradation of the specified stainless steel was observed that required significant investigation and preventative treatment.

In the design and construction of complex water treatment facilities, it is not uncommon for there to be issues such as these using the traditional design-bid-build form of project delivery. For over 60 years, Filanc has built its reputation on being able to collaboratively resolve issues during construction fairly and honestly. This project is an excellent example. Despite the multiple challenges the District, the designers and Filanc faced, we were able to calmly and fairly communicate our concerns and develop mutually agreeable solutions. Our experience has shown that on design-build projects, our ability to collaborate with owners and designers during design greatly reduces the number and magnitude of issues during construction.

Our Chairman of the Board, Jack Filanc, had over 50 years of water and wastewater construction experience, and was one of the original founders of the company. He was actively involved in estimating and value engineering for the company. Always a friend of the industry, Jack established an endowment in 2005 that provides annual general funding for the J.R. Filanc Construction and Engineering Management program at San Diego State University. This program was designed to fulfill the future professional construction engineering and management workforce needs of the local building industry.
