Brian Petty, P.E.

Brian Petty is a Senior Principal based in California with more than 17 years of experience focused on chemical and civil engineering, industrial water management, water and wastewater treatment plant design, and remediation system design. He consults with public and private clients to enhance their existing operations and address their environmental challenges.


As part of his process engineering and water/wastewater treatment experience, Brian has designed, implemented, and operated numerous water production, conveyance, and treatment systems. These systems range from an innovative, one-of-a-kind fixed-film bioreactor treating selenium and nutrients in urban runoff to complex Superfund groundwater extraction and treatment systems. Brian has managed numerous projects involving impaired water sources, including the design of pump-and-treat Superfund remedies with potable end uses as well as treatment plants for naturally-occurring inorganic constituents, 1,4-dioxane, heavy metals, emerging chemicals, disinfection byproducts, and trace organics. His team is currently advancing the state of the practice by working to develop an innovative biological treatment process for 1,4-dioxane.

Because he understands that water is key to business resiliency, and that water scarcity can put tremendous cost and compliance pressures on clients' operations, Brian advises his clients on ways to implement water footprinting studies and then decrease water use and develop sustainable supplies. In addition, he has designed materials recovery systems to reclaim resources such as trace precious metals from wastewater. Brian's designs for innovative water metering, treatment, and re-use programs allow many clients to make better use of scarce resources, improve business resiliency, and achieve sustainability goals.
