Check 1, Check 2, Check 3…

Los Angeles, California - The new and expanded 12 MGD Terminal Island potable reuse facility. Team members Ronnie Bemus (Xylem) and Austa Parker (Carollo) are shaking down the Industry First 12 MGD UV/Hypochlorite advanced oxidation system in Los Angeles CA. Every lamp, every sensor, and every control point must check out before this system can go into operation. Cross those “t”s and dot those “i”s Austa!

Think BIG

Design team members Adam and Hannah (Carollo) and Jim (Stantec) at the groundbreaking of the Metropolitan Water District's leading edge 0.5 mgd MBR/RO/UV AOP potable reuse demonstration system. Once operational, the project team will focus on MBR pathogen removal performance and downstream RO performance, allowing for the potential development of a massive 100+ mgd MBR/RO/UV AOP system.

Winner Winner Chicken Dinner!

Altamonte Springs (Florida) was awarded the 2017 WateReuse Association Innovative Project of the Year. Carollo was on-hand at the conference to accept the award on behalf of Ed Torres and Jo Ann Jackson from Altamonte Springs. A HUGE thank you to the City engineering and operations staff for their vision and dogged determination, to project co-funders at the St.

Pure Water Proof

The Arizona Pure Water Brew Challenge made its latest stop at the 2017 WateReuse conference in Phoenix. Our own Corin Marron was giving tours, and even did a spot on the Channel 3 News in Phoenix! ( Many thanks to the extensive dedicated team of Arizona engineers, scientists, and operators that made this a success.

Game On at WateReuse 2017 in Phoenix!

Whether it is water reuse or a "friendly" game of ping-pong, when it comes to excellence and determination, Eva (at right) and Pranjali (at left) have got game, and teamed up they are downright SCARY!. Thanks Pranjali for pushing ahead with up our exciting potable reuse work in Altamonte Springs and TOHO. Thanks to Eva for providing help and guidance just about everywhere.

Just the Facts, Austa

WateReuse Colorado is in high gear, working through important regulatory and public outreach issues for direct potable reuse. As part of Workshop #3, held in Denver, Sara Katz and Austa Parker walked through public outreach concepts, materials, and fact sheets.

Window to the Future?

The Soquel Creek Water District is searching for ways to supplement their community's water supply, including potable water reuse. As part of community outreach efforts, the District has developed an innovative trailer mounted "road show" to bring the concepts of water purification and water sustainability to their customers.

Vand Videnskab!

Danish pastries aside, exciting things are happening in Denmark and Carollo’s own Andrea Corral is in the middle of it. Andrea is one of 1,000 young global rising stars selected to participate in a 9 day innovation lab in Denmark called UNLEASH. UNLEASH provides a unique opportunity to go through a facilitated process of innovation, exploring real-life challenges within the 7 Sustainable Development Goals to define specific problems and come up with solutions. Andrea was nominated by Engineers Without Borders USA for whom she volunteers as the President of the Mountain Region.

Looking Back and Leaning Forward

Five years and >$12M in research has shown us that broad-scale Direct Potable Reuse can be safely implemented. Trail-blazing utilities and cities have seen this first hand and continue to push forward. As an industry, we should reflect on this monumental progress, congratulate ourselves, and then push-on. As we look to 2018, we see the rise of Ozone/Biofiltration, innovative bioassays for system monitoring, and real-time monitoring of industrial discharges, each a component of safe, sustainable, and reliable new water supplies.

Take the Challenge!

Back in Altamonte Springs Florida, where we are doing a series of virus challenges on the ozone, ultrafiltration, and UV disinfection systems. To date, the system has run for over eight months successfully producing new potable water from reclaimed water. This latest series of tests is looking to stress test the system and show clear performance for pathogen removal. Shown in photo: Pranjali from Carollo and Nate from Altamonte Springs.
