Shifting to a more sustainable future with better water treatment technology

Southern California has always struggled to secure a steady water supply. While aqueducts have met the county’s needs in the past, policymakers understand the dangers of being dependent on imported water. To chart a new course in the county’s history, the Metropolitan Water District (MWD) of Southern California and County Sanitation Districts of Los Angeles County decided to renew their focus on reuse.

MWD collaborated with Stantec to develop a strategic assessment for large scale water reuse in the Los Angeles Basin. Our team focused on the possibility of purifying effluent from the County Sanitation Districts of Los Angeles County and using it to augment potable water supplies. To turn these ideas into reality, we have designed a 1 MGD demonstration facility at the Joint Water Pollution Control Plant. This facility will showcase the effectiveness of our tools and techniques to the relevant regulators.  

Concurrent with the demonstration project, Stantec is providing conceptual planning for a 150 million gallons per day advanced water recycling treatment plant. The Carson Demonstration Facility will use a modified AWT process, utilizing both a submerged membrane bioreactor and ultrafiltration as a pre-filter to reverse osmosis. The data will be used to determine the appropriate process train for a potential full-scale facility for groundwater recharge and what could be the largest recycling project in the world.

I’m interested in the intersection of theory and practice—I think good engineering combines both.
