Testing
E&O Committee Item 6a Slide 11 December 10, 2018
Provide data for regulatory acceptance
Confirm viability of membrane bioreactor (MBR) process
Optimize full-scale treatment process design
Establish cost clarity for treatment
Confirm operational dependencies/ interfaces with LACSD
Provide vehicle for public outreach and acceptance
INITIAL TESTING PERIOD
FUTURE TESTING PERIOD
ONGOING
E&O Committee Item 6a Slide 12 December 10, 2018
Primary focus
Demonstrate pathogen removal
Achieve regulatory acceptance of MBR
Water quality from all unit processes will be monitored to ensure treatment goals are met
LACSD will characterize JWPCP source water & brine/waste streams from the AWT process
MBR Regulatory Acceptance
E&O Committee Item 6a Slide 13 December 10, 2018
Draft plan submitted in early October
Plan incorporated input from Independent Scientific Advisory Panel
Regulatory approval of final plan anticipated in early 2019
January 2019 meeting scheduled to review final plan
Testing to begin in March 2019 for 15-month duration

Feasibility Report (completed Nov. 2016)
Determined that 150 MGD program “could” be implemented
Did not answer questions: “how or should” program be implemented
Conceptual Report (scheduled Feb. 2019)
Examines and refines approaches as to “how” program could be implemented
Update to Board in March 2019
E&O Committee Item 6a Slide 17 December 10, 2018
Refines approach to overall program configuration
Examines potential options for phasing program
Presents cost estimate in 2018 dollars, and cost comparison between alternatives
Provides early assessment of potential future opportunities for DPR
