TT earns Engineering Excellence Award

Trussell Tech and Kennedy Jenks were honored by The American Council of Engineering Companies, California (ACEC California) as a 2017 recipient of its prestigious Engineering Excellence Award. TT and KJ were honored for Padre Dam Municipal Water District's Advanced Water Purification Demonstration Project in Santee, CA, which was developed to create a new, local, sustainable, drought-proof drinking water supply using state-of-the-art technology to purify East San Diego County’s recycled water. Padre Dam MWD retained Trussell Tech and Kennedy/Jenks Consultants to design, construct, and complete yearlong testing of an advanced water purification (AWP) demonstration facility. The demonstration facility was used to validate that the proposed treatment system provides a reliable path forward for both surface water augmentation and groundwater recharge, offering a new drinking water supply for East County.

Trussell Tech Participating in new WRF Project

Trussell Tech is proud to be participating in the Water Research Foundation's new project on conventional drinking water treatment of stormwater, graywater and treated wastewater. Shane Trussell will be serving as Co-Principal Investigator on the project, titled “Conventional Drinking Water Treatment of Alternative Water Sources: Source Water Requirements” (project #4665). The project will study the viability of these less-researched water sources possible potable supplies. For more information, click here.

California Conference of Local Health Officers

Dr. Brian Pecson is invited to speak to the California Conference of Local Heath Officers on the risks and impacts of pathogenic microorganisms on potable water reuse. The presentation will discuss public health risks and regulatory requirements, and demonstrate how potable reuse systems can be designed and operated to effectively control these risks and protect public health. The meeting will be held in Oakland on June 16, 2016, with representatives from state and local agencies, including EPA, CDPH, CDFA, CDPR and others.

White House Water Summit

Shane Trussell recently accompanied Cari Dale, the Water Utilities Director at the City of Oceanside, to co-present their IPR and Pathogen Removal Study at the White House Water Summit on March 22. This award is a great honor for Oceanside and Trussell Tech, reflecting our commitment to promoting sustainable water practices. The Water Summit coincided with World Water Day and featured panel discussions and invited speakers from the public and private sectors to raise awareness of priority water issues in the United States, and to catalyze ideas and actions to help build a sustainable and secure water future. 

A Youtube link to the recorded meeting can be found here.

Water Reuse 101

Trussell Tech is proud to be a part of an NWRI Independent advisory panel that worked with WateReuse Foundation, the American Water Works Association, and the Water Environment Federation to develop the recently-released Framework for Direct Potable Reuse. The guidance document is the first of its kind with the purpose of helping utilities develop guidelines for safely converting wastewater into municipal drinking water through the emerging practice of direct potable reuse (DPR).

Members of the panel included panel chair Dr. George Tchobanoglous of the University of California, Davis; Dr. Joseph Cotruvo of Joseph Cotruvo & Associates; environmental engineering consultant Dr. James Crook; Dr. Ellen McDonald of Alan Plummer Associates; Dr. Adam Olivieri of EOA, Inc.; Andrew Salveson of Carollo Engineers; and Dr. R. Shane Trussell.

Correcting the Standard Methods Langelier Saturation Index calculation

We are pleased to announce the publication of a Trussell Tech article, "Technical Note: Calculation of the Langelier Index at High pH," in the March issue of the Journal of American Water Works Association (AWWA). The article describes an error that Trussell Tech identified in the Standard Methods' (SM) calculation of the Langelier Saturation Index (LSI), and provides equations for correcting the error. Trussell Tech has updated its corrosion model and its blending worksheet to use the corrected calculation. Trussell Tech has also taken this opportunity to simplify the corrosion model and update the mineral analysis model and the blending worksheet. Total dissolved solids (TDS), rather than a complete mineral analysis, is now used to estimate ionic strength in the corrosion model, which simplifies the water quality analyses that are required to use the model. John Kenny is chairing the AWWA SM Joint Task Group on updating the LSI calculation method.
