North Marin Water District, Oceana Marin, California

This project involved an evaluation of alternatives for expansion of the wastewater treatment and disposal facilities for the Oceana Marin coastal community. The selected alternative was a sequencing batch reactor for treatment, followed by a mounded, slow sand filter system for effluent disposal in a sand dune area. The treatment facilities in fact were not expanded because of another more cost-effective project we undertook to optimize the disposal system
