Our Experience

From 1991 to Today: TrojanUV’s Water Reuse History

Our involvement in water reuse began over 25 years ago when we invested and participated in research initiatives to understand the science of disinfection for wastewater reuse. Today, we continue to focus on water reuse and the advancement of regulations, design guidance, validation and permitting requirements.

This timeline takes you through some important milestones in our water reuse history, from today all the way back to 1991.

    Title 22 Approval for the TrojanUVSigna

    The TrojanUVSigna is the first and only 1000 Watt low-pressure high-output-based UV system to obtain acceptance from the California Water Board and meet the strict coliform and virus disinfection criteria found in Title 22 of their recycled water regulations.

    Potable Reuse in Florida

    Florida has been treating and using non-potable recycled water for decades. They are now expanding their water policy and project portfolio to include potable reuse applications.

    We were selected to provide the UV pilot for Florida’s first potable reuse demonstration study using non-RO advanced treatment technology in Altamonte Springs (near Orlando).

    WateReuse Award Winner

    The WateReuse Association recognizes significant contributions to advancing water reuse and desalination. We were recognized as Manufacturer of the Year for providing equipment to new reuse facilities in Cambria, CA, Wichita Falls, TX as well as expanding advanced treatment facilities in Long Beach and Orange County, California.

    A First for Direct Potable Reuse

    After a decade of research, testing and construction, the Colorado River Municipal Water District (CRMWD) opened the doors to the Raw Water Production Facility and started treating water so it could be added directly into to drinking water supplies.

    Our TrojanUVPhox UV-oxidation system plays a critical role – removing contaminants and providing final disinfection.

  • World-renowned Indirect Potable Reuse

    The Groundwater Replenishment System opened its doors and became the largest IPR system of its kind, producing 70 MGD of recycled water. Our TrojanUVPhox UV-oxidation system was installed to disinfect microorganisms and destroy contaminants.

    Closed-vessel Water Reuse

    We introduced the TrojanUVFit, our Title-22 approved, compact and energy-efficient in-pipe solution. It was first installed for water reuse at the Randolph Park Water Reclamation Facility in Tucson, AZ.

    Addressing Drought in Australia

    Construction began on the Bundamba Advanced Water Treatment Plant (AWTP), the first Plant built for the Western Corridor Recycled Water Scheme in Brisbane.  It was the first indirect potable reuse facility in Australia, and part of the solution to the emergency drought conditions the region was experiencing at the time. We provided 32 TrojanUVPhox reactors, in record speed, to all three AWTP’s in the Scheme.

    Indirect Potable Reuse Emerges

    One of the first indirect potable reuse projects in the U.S. was at the Leo J. Vander Lans AWTF in Long Beach, California. Providing advanced oxidation, our TrojanUVPhox helps the City of Long Beach to stop buying costly imported water and produce their own recycled water for aquifer injection and prevention of seawater intrusion.

    UV Becomes Mainstream

    With a proven, safe and environmentally-friendly method of disinfecting recycled water now available, Plants of all sizes began installing UV for water reuse water disinfection.

    Full-scale UV

    We delivered our first full-scale water reuse system to the Lahaina Wastewater Reclamation Facility (WWRF) in Hawaii, a TrojanUV3000 system to disinfect 3 MGD of recycled water.

    In 2013, after 21 years, the Lahaina WWRF upgraded their equipment and expanded their treatment capacity by installing a TrojanUV3000Plus, which today can produce 9 MGD of treated, class R-1 recycled water.

    First NWRI UV Guidelines

    The NWRI (National Water Research Institute), in collaboration with the California Department of Health Services, published guidelines to assist in evaluating and implementing UV technology for reuse. Based on our research and experience, we provided input on technical and design matters.

    Pilot Testing UV

    The Rapid Infiltration & Extraction (RIX) treatment facility was built to convert secondary wastewater to reuse standards for the cities of Colton and San Bernardino, California. They piloted UV for final disinfection using our TrojanUV2000 system.

    With the results of the study, California’s Department of Health Services approved the use of UV and started updating the Title 22 Regulations to include UV as an option for disinfection of recycled wastewater.

    Research Leads the Way

    The University of California, Davis (UCD) initiated a research program to assess the feasibility of using UV light in meeting the stringent California Wastewater Reclamation Criteria. We provided two TrojanUV2000 disinfection systems and financial support to this important and successful research.

    The UCD team made the results of their study public in a 1993 edition of the Water Environment Research Journal.
