Certification Course Curriculum
The curriculum provides detailed instruction on water-harvesting systems, planning, design, and installation for retrofitting urban areas. The course includes:
- Integrated site assessment, planning, and design of rainwater harvesting earthworks, rain tanks, and greywater systems
- Hands-on training workshops to install water-harvesting systems
- Instructor-led session activities to practice and apply knowledge gained
- Final real-world water harvesting design practicum to earn certification
The Water Harvesting Design Certification course is designed and administered by WMG staff with assistance from industry professionals who teach and implement water-harvesting practices.
Meaning of Certification
Certification signifies that you have received thorough training and demonstrated a mastery of essential core concepts outlined in the curriculum.
To earn certification, participants must earn 90% on a final real-world water harvesting design practicum based on application of systems design taught in the course. Once you earn certification, you will be listed on WMG’s website as a WMG Certified Water Harvesting Practitioner, including your profession and/or business name.
Certification will teach you to:
- Integrate water harvesting systems with other design considerations (energy conservation, aesthetic design, food production, wildlife habitat, etc.)
- Calculate rainwater and greywater potential monthly supplies
- Estimate indoor and outdoor monthly water demands to develop and balance a site-based water budget
- Size, design, and build water harvesting earthwork features (eg. infiltration basins, berms, swales)
- Design safe and effective greywater systems for laundry, sinks, and showers
- Construct greywater systems from a laundry machine wastewater or other fixture to irrigate landscape
- Design, size, and install rain tanks
- Design water-harvesting systems to support small-scale food production (including earthworks design, rain tank design and application, and soil improvements)
- Design all of the above systems while incorporating safety and health considerations
- There are no formal educational or professional requirements for this course, but applicants should have the desire and capacity to master a large amount of information in a short time.
- Highly recommend participants become comfortable with unit conversions for lengths, areas, and volumes and practice and apply water harvesting calculations found in course preparatory handouts.
- Ability to work outdoors. Course participants will conduct site assessments and assist in hands-on system installation workshops, including plumbing, digging, planting, and rock work.
- Participation in the entire training program. If a session is missed, the student must make up that session at a later date to earn certification.
- A passing grade of 90% on the final design practicum.
Registration: $1,100 (Student discounts available). Cost includes lunch and snacks provided each day of the training.
