PRIOR BOARD ACTIONS:
June 5, 2023, Regular Meeting, Agenda Item # 23-311 - Approved Hazen and Sawyer Task Order 2020-07 for engineering design and bid phase services for the Crooked Creek WRF UV Disinfection project.

The current equipment at the Crooked Creek WRF is at the end of its useful life, and the manufacturer has released a bulletin stating that it will no longer support this model of UV equipment due to the model being outdated with their current manufacture of more efficient UV equipment. Therefore, an evaluation was completed in January 2023 to determine the best option for replacement of the existing equipment since the facility will remain in operation for the foreseeable future.
The Board previously approved Hazen and Sawyer Task Order 2020-07 on June 5, 2023, for engineering design and bid phase services for this UV replacement project in the amount of $348,560.00.
