COWA is Advocating for onsite water management solutions that are: scientifically sound, economically feasible and environmentally resilient.

Our goals are to:
  • Increase public awareness and information encouraging localized water solutions.
  • Promote best management practices for system installations, operations and maintenance.
  • Streamline and modernize regulatory standards for onsite water technologies.
  • Advance legislation and policy that embrace localized water as part of a comprehensive, sustainable management plan.


COWA’s Mission is to promote environmentally and economically sound onsite water technology and management practices.

COWA serves both the public and private sectors of its membership by providing technical updates, training, networking opportunities, and advocacy for best management/industry practices.

From the beginning, our philosophy has been that onsite water is a technical industry and that best decisions are made when based on sound science, facts, and education. Training is a key element that is in short supply within this industry. COWA sets out to fill the void.
