Ojai Valley Sanitary District
Wastewater Treatment Plant Upgrade

Project Description. The $20 million project upgraded the plant effluent into the environmentally sensitive Ventura River. The 2.5 year project essentially removed and replaced all existing process elements and changed the process from trickling filters and RBCs to Oxidation Ditches. The project required major temporary facilities for on-going operations. The project was reduced from three (3) construction phases to two (2) phases based on the contractor’s proposal to temporarily convert existing equalization basins to chlorine contact basins during the work. The project was completed with less than 2% change orders.
