Water+ Plants Improvements Project Design

The City of Sacramento Department of Utilities seeks a design team for the Water+ Plants Improvements Project, which will make the City's two surface water treatment plants, the Sacramento River Water Treatment Plant (SRWTP) and the E. A. Fairbairn Water Treatment Plant (FWTP), safer, more reliable and more resilient. The project replaces assets that have reached the end of their useful lives, upgrades treatment to handle changing river water quality and drinking water regulations, and expands SRWTP capacity from 160 to 310 million gallons per day in phases. Basis of design reports for both plants are the starting point for design. The contract has four phases: design of all elements through 90 percent; 100 percent design and construction support for FWTP resiliency improvements, equipping of two FWTP groundwater wells and a short list of SRWTP items; the same for the remaining SRWTP resiliency work and the North B Street 36-inch transmission main replacement; and the SRWTP expansion. Design must sequence temporary and permanent work around limited winter plant outages so water production continues throughout construction. The firm also prepares environmental documentation (including NEPA support and an addendum to the existing EIR for the wells), a solar cost-benefit study, finish reservoir flow modeling, structural load ratings, a drainage study, pilot testing support, control strategies, standard operating procedures, value engineering and coordination with utilities and regulators.
