With the recent release of Ontario’s Guidelines for Residential Rainwater Harvesting Systems (RWH) (read them here), the Toronto and Region Conservation Authority (TRCA) and Connect the Drops have partnered to develop and offer a series of one-day training seminars for contractors, builders, designers, architects, regulators, or anyone interested in learning about the design, installation and management of RWH systems.

The guidelines cover a variety of topics, including: sizing rainwater storage tanks, installation of rainwater (non-potable water) plumbing, rainwater treatment, as well as how to design RWH systems to operate during dry periods and handle overflows from the tank.  The document focuses upon residential applications, but is also a valuable tool to assist with the design, installation and management of RWH systems in ICI (industrial, commercial and institutional) buildings.

TRCA’s seminars will focus upon the regulatory and technical aspects of RWH systems for both residential and ICI buildings. Participants will be provided with a copy of the Ontario Guidelines, and receive step-by-step guidance on the material in the guidelines, and how to use it to implement rainwater harvesting projects.  The seminars will include a variety of teaching formats, including instructor-led instruction, group exercises, and includes a 45-minute design charrette.
