From Design to Completion: Con J. Franke Electric's Contribution to Building San Francisco's New Water Resource Recovery Facility

September 25, 2023

We’re proud to share our involvement in the design-build of the new Treasure Island Wastewater Treatment Plant, located in San Francisco, California. The water resource recovery facility is part of the San Francisco regional redevelopment plan. Co-project managers, Barry Frain and Nicco Chavez are collaborating with on-site foreman Mike Wolff.

Con J. Franke Electric is involved with designing and building a new Water Reuse and Recovery Facility capable of processing an average daily influent flow of 1.3 million gallons a day, with a peak wet-weather flow of 3.9 million gallons a day.

The man-made island, located between San Francisco and Oakland, is anticipating an increase of 20,000 residents by 2032 (eight times the current population). This water resource recovery facility is key to ensuring a sustainable water recycling process and will replace the current small treatment facility with dated infrastructure that serves the 2,500 people currently living there.

The Con J. Franke Electric involvement with this $157,000,000 budgeted project started in January 2023. Site excavation started in August 2023, and we are still in the Design Phase with PCL Construction and Stantec Engineering. Our on-site involvement will ramp up quickly over the coming months. The project is due to be completed in September 2025.

Our team is responsible for all the electrical work for the buildout of the incoming Utility Service connection at 12470 volts to 480-volt distribution, installing a 480-volt switchgear with transfer switch controls to connect 1000 kilovolt amperes (kVA) of standby generation, as well as installing distributed control system (DCS) controls; and security, CCTV, fire alarm, and communication systems.

As part of a water treatment facility, the project includes many buildings to support the plant influent flow including, Influent Pumping structure, Headworks, Biological Nutrient Removal (BNR) basins, Membrane Bioreactor (MBR) basins, Solids Handling, a Raw Water Pumping structure, a Storm Water Pumping structure, and Odor Control facilities. To support the process flow, there is also an Administration building and Maintenance building.

As with all our commercial electrical projects, we are ensuring success by assembling a team of experienced personnel. The initial Design Support Team consists of three in-house Con J. Franke Electric employees and the Construction Team will peak at 20 IBEW electricians.

The biggest challenge with this project is accommodating multiple owners and design team changes due to the design-assist nature of Con J. Franke Electric’s role. Coordinating among multiple individuals can be time consuming, but we have the expertise and ability to facilitate decision making to continually meet the project milestones.

The project design milestones followed by the Construction Team are very aggressive. There are still supply chain issues in the construction world requiring strategic alignment between design and supplier availability of materials. Con J. Franke Electric will continue to monitor and manage supply concerns and deadlines so the project can keep moving forward in each phase.


Despite the challenges, everyone involved is looking forward to the new Treasure Island Wastewater Treatment Plant. When it’s complete, it will meet or exceed the National Pollutant Discharge Elimination System Requirements for Water Quality. The facility will also meet the San Francisco Public Utility Commission Wastewater Enterprise Treatment Division Standards!

We are excited about the positive community impact this project will have and how it will support the rapidly increasing residential population.
