Project Challenges/Solutions

The Chino I Desalter treatment plant is a critical source of supply to the Chino Basin Desalter Authority. The construction activities had to be performed within the operational treatment plant such that CDA’s ability to meet its customer’s demands for treated drinking water was not reduced in terms of quantity or quality. Butier’s CM Team ensured that the Contractor’s work did not impair the operational capabilities of essential elements of the treatment process or reduce treatment capacity below levels sufficient to meet demands for water throughout the contract time.
