The City of San Diego Point Loma Wastewater Treatment Plant, which is located on the Pacific coastline, is “the largest wastewater treatment plant in the Metro System” and “treats about 190 million gallons per day.” “The plant is currently undergoing upgrading and expansion of its treatment processes and support facilities.” Rust Bullet® was applied to the already rusted frame and surface of their new one million gallon digester, before being put into service early in 2002.
