IEUA developed a partnership with the Los Angeles County Sanitation Districts to create the Inland Empire Regional Composting Authority (IERCA). The IERCA determined that recycling biosolids into a high quality compost product, in a fully enclosed, local facility was the best approach to overcoming the challenges of biosolids management. The Inland Empire Regional Composting Facility (IERCF) located in Rancho Cucamonga, is the nation’s largest fully enclosed composting facility. In operation since 2007, the IERCF is an excellent example of IEUA’s ability to provide a regional sustainable solution to biosolids management.
