Project Detail

Wastewater UV disinfection reduces energy costs, increases capacity

Total Cost
$2.3 million
Date Completed


The Oakland Wastewater Treatment Plant (WWTP) required improvements to the ultraviolet (UV) disinfection system. The existing UV disinfection equipment, originally installed in 2000, was nearing the end of its useful life and needed to be replaced with a more modern and efficient system.


Bartlett & West led procurement, engineering, bidding and construction management services to replace the existing UV system with a two-channel system capable of disinfecting higher flow rates while using less energy per lamp and automating control of lamp intensity. Aeration improvements were also made during the construction.  


Updates to the UV disinfection and surface aeration systems allowed plant operations to reduce energy consumption and operator input while increasing capacity for both secondary and tertiary treatment.
