For over 60 years, CASA has served as the leading voice for clean water agencies on regulatory, legislative and legal issues. We are the leading California association dedicated to advancing wastewater interests, including the recycling of wastewater into usable water, generation of renewable energy, biosolids and other valuable resources. Through our efforts, we help create a clean and sustainable environment for California.
We represent over 100 public agencies that engage in the collection, treatment or disposal of wastewater, resource recovery or water recycling. Our membership has grown to also include over 80 associate members involved in the water quality field. Associate members include engineering consultants, service and technology providers, accountants, attorneys and financial institutions.
CASA provides leadership, advocacy and information to members, legislators and the public and promotes partnerships on clean water and beneficial reuse issues that protect public health and the environment.
CASA is the most trusted and valued influence on clean water and renewal resource law, regulation and policy on issues important to CASA members and the public they serve.
