A presentation by the Spokane County Conservation District prompted Craig V. to contact O2Compost. His Benchmark system was constructed in 2013 and now composts the manure from 18 to 24 horses. The finished compost is spread onto the pastures and used in the garden and greenhouse. The excess product is sold. Craig has been happy with his decision to add an additional storage bay to the original structure design, and he appreciates the technical support and advice from O2Compost engineers.
