Mountainside Farms produces UltraPure TM milk at their facility located in Roxbury, NY. The Wastewater treatment plant is permitted for 51,000 GPD. An upgrade in 2011 and 2012 led to the installation of two aeration basins as part of a new Membrane Bioreactor (MBR) process. The upgrade also included the construction of a sludge conditioning tank and two enclosed sludge storage tanks with odor control.  This Plant is operated by Cedarwood Environmental Services.
