Expanded Greywater

WMG's Expanded Greywater Technical Training will teach how to utilize all your greywater sources—laundry machines, bathroom sinks, showers, and kitchen sinks—for water conservation, food production, and landscape irrigation.
Course description

Greywater use helps conserve water, reduce energy and chemical use in treatment plants, and deliver nutrients to your soil. With broader acceptance and more municipal support for greywater use, the demand for trained greywater installation professionals is growing. This course offers you an in-depth, hands-on education in implementation of a variety of proven systems, including gravity-fed kitchen sink, Laundry-to-Landscape (L2L), and collection-and-pump greywater systems.

The course blends classroom lectures, site assessments, design exercises, hands-on workshops, and a tour of existing systems.
