The Inland Empire Regional Composting Authority (IERCA) was created as a public entity on February 27, 2002 by a Joint Powers Agreement (JPA) between the Inland Empire Utilities Agency (IEUA) and Los Angeles County Sanitation Districts (LACSD). This agreement empowered both IEUA and LACSD to acquire, construct, operate and maintain a composting facility. IEUA and LACSD have jointly evaluated composting as an economically and environmentally-sound method of beneficially reusing biosolids that are generated from the wastewater treatment facilities operated by each.

OUR MISSION

The Inland Empire Regional Composting Authority protects the environment by converting waste products into high quality compost through sustainable biosolids management, benefiting our partnering agencies and communities.
