Las Virgenes' commitment to the environment is demonstrated at this unique facility. A small percentage of biosolids from Tapia is applied to fertilize feed crops on Rancho's 91 acres of farmland. The majority of the biosolids go through an automated composting process, which produces about 20,000 cubic yards of rich, agricultural soil amendment annually. Over a 10-year period, Rancho will divert from local landfills enough solids to fill a football stadium to a height of 7-stories.

One of only five of this kind in the world! In keeping with the district's commitment to environmental stewardship, the district and it's joint venture partner, Triunfo Sanitation District, successfully launched this state-of-the-art fuel cell co-generator. The $2.6 million project was financed by a $958,240 California Energy Commission grant, plus $400,000 from the U.S. Department of Defense, with the balance covered by the Joint Venture partners. The expectation is to recoup this investment within less than 10 years; because of the money saved, the district will not be purchasing power from an outside source.

The two fuel cells - each the size of a large truck trailer - take the methane gas, a by-product of the composting plants process, and turn that gas into the power which runs the facility. The cells have a combined ability to generate enough power to serve the average needs of 300 households.
