Perkins Engineering Consultants, Inc. served as a subconsultant to Brown and Gay Engineers, playing a lead role in assessing and prioritizing odor sources at the city of Granbury’s wastewater treatment plant. The City commissioned this evaluation as a proactive step in addressing extensive lakefront residential development in areas immediately adjacent to the facility. This evaluation, completed in 2007, identifies the plant’s grit/grease structure and influent lift stations as the most cost effective process units to target for initial odor control efforts. Perkins Engineering Consultants, Inc. designed odor abatement improvements to these two areas, including an upgrade to the BioCube® units at the plant’s existing lift station and a new 1000 CFM AerBios® unit at the new grit basin. The project was completed and successfully passed performance tests in 2010.
