Jacobs’ £1bn California wastewater plant: design-build and process risks for engineers
Reviewed by Joe Ashwell
First reported on New Civil Engineer
30 Second Briefing
Jacobs has been appointed by the San Francisco Public Utilities Commission as progressive design-build contractor for the £1.09bn ($1.47bn) Southeast Treatment Plant Nutrient Reduction Project, a major upgrade to the city’s largest wastewater facility. The contract will focus on advanced nutrient removal to meet tightening San Francisco Bay discharge limits, likely requiring high-rate biological treatment, upgraded clarifiers and significant process intensification within an existing urban footprint. Civil and process engineers can expect complex brownfield staging, hydraulic reconfiguration and stringent continuity-of-service constraints during construction.
Technical Brief
- Contract value is stated at £1.09bn, equivalent to approximately $1.47bn capex.
Our Take
Jacobs’ role on the Southeast Treatment Plant Nutrient Reduction Project in California sits alongside its recent programme-delivery mandates on Dublin’s £8.4bn MetroLink and Germany’s Konrad radioactive waste repository, signalling that major public clients are repeatedly turning to the firm for complex, long-horizon infrastructure in both transport and environmental sectors.
Within our 916-item Infrastructure corpus, Jacobs appears frequently in large ‘Projects’ and ‘Contract Award’ pieces, suggesting the San Francisco Public Utilities Commission is aligning with a contractor that already has a strong track record navigating politically exposed, multi-billion-pound schemes in Europe and the UK.
The progressive design–build selection for this US wastewater scheme echoes calls from Jacobs’ tunnelling leadership in the UK for earlier constructability and geotechnical input, implying SFPUC is likely seeking to de-risk redesign and interface issues by locking in the contractor during the formative design stages.
