Kennedy Jenks provided comprehensive program management services that included planning, design, and engineering services during construction for a $150M water, wastewater, and recycled water infrastructure to support a new 20,000-person community north of Fresno California, known as Tesoro Viejo. The project utilizes an alternative project delivery approach. The new infrastructure plan includes: a 0.6-mgd microfiltration water treatment plant (expandable to 6.0-mgd), and a 2.4-mgd MBR water reclamation facility. The water reclamation facility was designed to produce recycled water, meeting Title 22 requirements for unrestricted irrigation reuse, and 0.5-mgd of advanced treated water for groundwater recharge and other recycled water applications. The water reuse strategy developed by Kennedy Jenks also enables zero liquid discharge.
Kennedy Jenks designed this project in multiple construction packages, which were released in phases. During the planning stage of the project, KJ worked with Tesoro Viejo to develop a phasing and cash-flow plan to deliver the infrastructure consistent with the pace of development and available funding streams.
This approach also supports the development of short-term and long-term water reuse strategies to enable wastewater treatment and reuse with zero liquid discharge (all water is reused). The innovations Kennedy Jenks brought to the project include:
- Progressive design/build partnership for new potable water treatment plant, wastewater treatment plant, and raw water pipeline.
- Defined costs from a single responsible entity early in the project development allowed for early start/completion dates and permitting of critical-path elements to meet client’s development schedule.
- Locating the water treatment and wastewater treatment facilities on the same site optimized land usage for development and helped to streamline construction.
