About this Project
Our staff designed an enhanced wastewater system for the Mayacamas Ranch resort located in the hills above Calistoga in Napa County. The system was designed to treat wastewater from the resort’s commercial kitchen and guest units. The wastewater system is designed to treat approximately 1,500 gallons of wastewater per day and employs an OSI Advantex media filters, including three OSI AX20 packed bed textile filters. Effluent from the treatment system is reused for landscape irrigation using a subsurface drip disposal system and also includes a backup shallow pressure dosed leach field system.
