About this Project

Nestled on the western slope of the Santa Lucia Mountains in Big Sur, California, the Post Ranch Inn is a luxury resort committed to eco-tourism and sustainable development and to preserve and protect the site and environs of the unique coastline.  Our staff designed and supervised the construction of an enhanced biological treatment system designed to treat the wastewater at the Inn to advanced secondary levels. The system reduces the biochemical oxygen demand (BOD) and total suspended solids concentrations by greater than ninety (90) percent.  The system uses a subsurface two-stage trickling filter to achieve a highly treated effluent.  The system is designed to treat 15,000 gallons per day. The main control panel includes a SCADA system to allow for remote operation and monitoring.
