The IWMA is a Joint Powers Authority (JPA) formed in 1994 by San Luis Obispo County and the Cities and Community Service Districts (CSDs) within it to more effectively manage solid waste programs. We're a public agency that was created in response to AB 939 and is governed by a Board of Directors elected to represent each of our member jurisdictions. The IWMA represents 20 jurisdictions and serves a population of over 282,000 through management of our 44 solid waste and recycling programs.
