Our Story

Pete Law (P.Eng.) created Rainwater Management Ltd (RWM) in Spring 2006. He grew up in a world of construction with his father being a contractor who did mainly Civil work. So, a career path in Civil Engineering fit well. Pete spent a few years working in the pre-cast concrete industry as the Stormceptor representative where he learned not only about stormwater treatment but also about the manufacturing and application of pre-cast concrete products (pipe, box culvert, vaults, manholes, catchbasins etc.). An opportunity arose to represent a Stormwater Treatment system and thus began Rainwater Management.
