SLIDE 17:  Four Ways to Harvest

by Nate Downey

In my talks, public presentations, and interviews, I almost always explain that there are four forms of water harvesting, and my lecture at the Association of Professional Landscape Designers was no different in this respect. Active water harvesting is the form that pumps water out of a water storage tank called a cistern. Passive water harvesting stores water in the soil. Wastewater harvesting recycles greywater (from clothes washing machines, bathroom sinks, showers, etc.) and blackwater (from kitchen sinks, dishwashers, and toilets). Community water harvesting deals with the use of stormwater on a community-wide scale.
