The American Rainwater Catchment Systems Association is to promote sustainable rainwater harvesting practices to help solve potable, non-potable, stormwater and energy challenges throughout the world.
Our memberships consist of professionals working in city, state, and federal government, academia, manufacturers and suppliers of rainwater harvesting equipment, consultants, and other interested individuals. Membership is not limited to the United States, and we encourage all rainwater harvest practitioners and enthusiasts to join our organization.
An ARCSA membership offers many benefits to anyone interested in rainwater harvesting. Whether you're a professional or a backyard amateur, you're sure to find a host of useful information in the Members only section of our website.
With the launch of the ARCSA website, our leadership recognizes that members ARE our most important assets. By tapping into our member’s wealth of knowledge, we have created a professional website that is timely, easy-to-navigate, vibrant, comprehensive, thought-provoking and valuable.

When you seek a professional, you look for a nationally recognized standard accepted by industry leaders. An ARCSA Accredited Professional (AP) has achieved the only nationally recognized rainwater-harvesting credential, which tells consumers and regulators that they have been screened, taught and tested by the best in the business. Not resting on our accomplishments, we are now offering members specialized 300-Level workshops and “Post Graduate” recognition as Certified Professionals.
This elevated "graduate level" category of rainwater harvesting professional tells consumers and regulators that this rainwater-harvesting professional is an Accredited Professional that has gone beyond that designation and fulfilled at least 42 hours of additional study, attended an ARCSA Design and Construction workshop and has passed a comprehensive examination. Keep an eye on the website as this program develops.
