Rancho Las Virgenes (RLV) Composting Facility provides for the beneficial reuse of biosolids removed during the wastewater treatment at the Tapia Water Reclamation Facility.  This facility is operated by the Las Virgenes Municipal Water Distrct.  Due to the facility’s location, near a residential and commercial area, odor control has always been of prime importance to the successful operation of this plant.When the facility first opened in 1994, it did not use a BacTee biofilter – instead it used a “pipe-in-gravel” aeration floor system.  In 2001, the odor control facility was expanded to accommodate increased air emissions from the facility and BacTee was selected over the existing flooring system.
