National Standards and Professional Certification: Why ARCSA Membership Matters

As rainwater and stormwater harvesting systems become more widely adopted, the need for clear, reliable standards has never been more important. Standards ensure systems are designed and installed safely, operate effectively, and meet regulatory requirements. They provide confidence to property owners, clarity for code officials, and consistency for industry professionals.

ARCSA International plays a leading role in advancing these protections through the ARCSA/ASPE/ANSI Standards 63 & 78, which establish best practices for rainwater catchment system design, installation, inspection, and maintenance. These standards help elevate the credibility of the entire industry while supporting safe, code-compliant implementation across jurisdictions.

ARCSA is currently seeking consensus-body members to participate in the ongoing standards development process — an opportunity for professionals who want to help shape the future of water reuse. 

Certification is another cornerstone of ARCSA’s impact. The association’s professional training for designers, installers, and inspectors demonstrates technical competence and a commitment to industry’s best practices through ASSE Rainwater and Stormwater Harvesting Personnel Certifications. For professionals, certification strengthens credibility and differentiates services in a competitive marketplace. For clients and regulators, it signals trust and accountability.

Across the country, standards-compliant systems installed by ARCSA/ASSE-certified professionals are proving the value of formal training and oversight — from commercial facilities integrating stormwater reuse into site design to properties relying on rainwater as a primary supply. These successful projects reflect not just innovation, but professionalism grounded in recognized standards.

As one ARCSA/ASSE-certified member shared:

“Becoming ARCSA certified strengthened our credibility with clients and inspectors. It gave us a competitive edge and positioned our company as a trusted authority in rainwater system design and installation.”

Standards build trust. Certification builds careers. ARCSA membership makes both possible.
