Canadian Association for Rainwater Management


Our mandate: 

To bring awareness, educate, and conduct research in best practices for rainwater and stormwater management across Canada.

With increasing environmental awareness and concerns, addressing the issues of rainwater management has become paramount to the success and longevity of many residences and business operations. CANARM has been established to deal with the vast array of very positive actions undertaken by entrepreneurs, homeowners, and designers, and to help consolidate and focus jurisdictional governances across Canada.

CANARM is a national organization of individuals, businesses, and consultants with a keen interest in the future of rain and storm water management practices. We are closely linked to ARCSA (American Rainwater Catchment Systems Association) and many other related groups.
