Aurora Ridge Dairy is a 2,000-cow dairy operation located near the Village of Aurora in Cayuga County, New York. The farm is owned and managed by William Cook. Digester construction began in late summer 2008 and commissioned in August 2009. Digester construction was funded in part by a USDA Rural Development grant and by NYSERDA. Digester effluent is separated using FAN screw-press separators and post-digested separated solids are used for freestall bedding.
