Burlington, Mass., April 24, 2024 — This month, a Haley & Aldrich team accepted a prestigious honor from the California Geotechnical Engineering Association (CalGeo): the 2023-2024 Public, Small-Budget Outstanding Project Award.  

The winning project — Phase 2 of the Brentwood, California, Wastewater Treatment Plant expansion — was led by Senior Principal Engineer Dan Peluso, P.E., G.E., Env SP, with Senior Technical Expert and Geotechnical Engineer Mark Myers, P.E., G.E., contributing to ground improvements required for the remediation of the liquefaction hazard. Ronaldo Longoria, P.E., and Grace Silverboard contributed to the project submission. 

Each year, a committee of experts uses the Outstanding Project Awards to shine a spotlight on the best geotechnical projects in California, with the awards formally presented at CalGeo’s annual conference. The committee selects the year’s finest work in several categories, providing all in the field “the opportunity to learn from exciting, innovative approaches to challenging situations.” 

The multi-year, $70 million Brentwood project will increase the treatment plant’s capacity from 5 million gallons per day (MGD) to 6.4 MGD to serve the anticipated growth of Brentwood’s population as per the City General Plan. During its initial investigations, the Haley & Aldrich team identified liquefiable soils underlying the site and provided recommendations to mitigate this hazard. 

“It’s an honor to receive recognition for our work,” said Dan Peluso, “especially given that the project removes the facility as a bottleneck to the continued growth of the thriving Brentwood community.”  

The team members who earned the award joined Haley & Aldrich as part of its 2023 merger with Cal Engineering & Geology (CE&G). CE&G projects also earned three Outstanding Project Awards and two honorable mentions between 2016 and 2021.
