Welcome to Carollo's Thought Leadership Blog

As a water only firm, Carollo has some of the most innovative and forward-looking people in the industry. On this page you will find thoughts, ruminations, and experiences from a variety of Carollo's discipline practice leaders. We invite you to add to the discussion and become part of Carollo's thought leadership in water engineering.


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.

Hard Hat Harold

Rio Rancho NM. Harold Wright, Melanie Sikes, and the Carollo team are at WWTP #2 in Rio Rancho New Mexico. Our work with the City will find a newer/better/more efficient UV system at WWTP #2. Excited to be working with Jim Chiasson and his team!

Big Wheels Keep on Turning…

Potable Water Reuse is on a roll, with one project after another successfully producing new water. Funded by the Arizona Water Innovation Challenge Prize, a broad crew of utilities, consulting engineers, university professors, and equipment suppliers have developed a mobile potable water reuse system that is now travelling across Arizona turning wastewater safely into water…and then into beer. Thanks to some of Carollo’s own on this effort (George Maseeh,  Corin Marron , and Viking Edeback!).

Double, double toil and trouble, fire burn and cauldron bubble...

Not Shakespeare, but just as artistic. Pranjali Kumar and Tyler Smith working with JEA (Jacksonville FL) on finding the right chemical concoction that disinfects to meet permit, minimizes DBP formation, and has no significant toxicity. Three weeks of extensive field testing will dictate if chlorination can be used to replace UV at the Buckman WWTP.

Israel Technology Exchange - San Jose, CA

Back in California, NWRI's Suzanne Sharkey kicking off a technology exchange discussion at a WateReuse Association International Advisory Group workshop at the Santa Clara Valley Water District's purification center. Guests included our host the Santa Clara Valley Water District (thanks Hossein!), Ranaan and Avner Adin (private consultants from Israel) and Andy David (Israel's Consulate General), engineering consultants from across California, and Bahman Sheikh and Eric Rosenblum (thanks guys for setting this up!).

El Paso Action

El Paso Water's next phase of potable water reuse is now in motion. First steps include a grant funding action plan, looking to leverage existing Title XVI authorization to help move this project forward.

Chug! Chug! Chug!

Altamonte Springs Florida. Pranjali Kumar (Carollo) having a cool drink of freshly purified water in Altamonte Springs. Extensive water quality results are rolling in (thanks SNWA and UC Davis!), demonstrating the safety of direct potable reuse using Ozone/BAF, UF, GAC, and UV AOP...look closely...NO RO! We are grateful to the whole team, the vision, construction, and operational support of Altamonte Springs, the robust treatment systems from the Suppliers (Xylem, BiWater/Toray, Calgon Carbon, Trojan, Hach), and the collaborative effort from FDEP and SJRWMD.

El Paso and the Chihuahuas!

The chihuahua’s history remains a bit of a mystery, but evidence suggests they descended from the Techichi, a companion dog of the Toltec civilization in Mexico over 1000 years ago. The chihuahua is named after the Chihuahuan Desert, which stretches from Mexico into West Texas, Southern Arizona, and New Mexico.
