The construction of a project to improve the quality of the water of $ 341 million for the Municipal Services District of the Bay of California reached half the mark this summer, as the crews began to form concrete in the portions of a large installation of stepping water treatment at 65 feet below the level of the ground.
The project, which is expected to be completed by 2027, will update the existing Orinda treatment plant, and replace the components of aging chemical treatment with ultraviolet disinfection and chlorine.
The Utility District identified the need for the project in 2017 when it changed its primary water source from the Mokelumne River on the Sacramento River and realized the need to improve the quality of water in the light of the fluctuations of climate change.
Flatiron Dragados is the main contractor of the project, which will introduce ultraviolet disinfection and a chlorine contact basin to improve treatment processes and reduce disinfection by -products formation. The members of the design team include Carollo Engineers, Statec and Arcadis.

The project requires a two -level excavation, which is a tunnel operation above and the construction of concrete slabs below, which has required the reduction of selection and innovative sequencing to maintain stability and progress.
Currently, the crews are focused on the excavation of two levels, both for the ultraviolet disinfection structures and for the chlorine contact basin, with the slab that forms the ceiling of the UV chamber, which serves as the basis of two floors maintenance and an electric building.
Manager Jared Herrington says that the team has carefully work on the project to maintain construction on the court.
