This course is applicable across a wide range of trades and professional practice.  As an ancient, yet ever new practice, the harvesting and use of rainwater is fast becoming a major issue, not only in third-world countries, but also in more developed regions, and in particular, large urban centers. Using the foundational  concepts of rainwater management, and implementing key components of rainwater harvesting, professionals and trades practitioners will be able to design, create and manage quality systems in a sustainable and environmentally ethical manner. This course partially satisfies the Gaia College Diploma in Organic Land Care. Earn generous continuing education credits for landscape professionals to maintain industry certifications (CNLA, BCSLA, NALP, MGOI, IPM, NOFA, SOUL).
