The project is currently at 73% completion, set to finish in spring 2026, with most of its underground piping done and the bulk of the concrete structures built, says Jimmy Draper, Shimmick southwest division vice president. The focus now is on the scope of services for mechanical and electrical systems.

Also on the project are a Parsons-Black & Veatch team as construction manager; Carollo Engineers as designer of record; and Stantec as program management consultant.

The plant forms part of the $1.5-billion first phase of the Pure Water progam. Phase two will add capacity for purifying an additional 53 mgd, with costs still being prepared. Almost half of the city’s local water supply will come from the progam by 2035. It's the “largest integrated infrastructure program … San Diego has ever undertaken,” according to the city.
