Site work for a water / sewer project in Fountain Valley, California. Completed plans call for site work for a water / sewer project.

OC San seeks to implement a Biosolids Deep Well Injection System (BDWIS) to provide a sustainable, long-term biosolids management solution for Plant No. 1 and Plant No. 2. Currently, OC San produces over 500 wet tons per day of dewatered biosolids, which are transported up to 280 miles to land application and composting sites in California and Arizona. Deep well injection offers an alternative by permanently sequestering biosolids into deep, porous geologic formations more than 5,000 feet below ground, beneath multiple impermeable layers. This approach isolates persistent contaminants, reduces transportation-related greenhouse gas emissions, and supports opportunities for carbon credit generation. The project will be delivered through a Progressive Design-Build (PDB) contract, engaging a Design-Builder early to collaboratively develop the design, manage permitting, refine cost estimates, mitigate risks, and plan construction prior to establishing a Guaranteed Maximum Price (GMP). An Owner’s Advisor (OA) will also be contracted for the project duration to provide technical expertise in deep well injection and progressive design-build project delivery, as well as professional services for CEQA permitting. All parties interested in participating in the upcoming solicitation must be registered on OC San’s Vendor Portal in OpenGov. Firms must select NAICS Codes 23, 237, 54, 5413 and any applicable codes to their industry, and provide correct contact information for notification of solicitation notices.
