About this course

With water resources low in half of the United States and climate change continuing to warm the planet, water conservation is more important than ever. Finding ways to use - and reuse - water responsibly in both residential and commercial contexts will help us continue to have access to clean drinking water for years to come.

One way to responsibly reuse water which is growing in popularity is through greywater systems. Greywater is water that has already been used in your home or in a building. It comes from showers, sinks and washing machines. In most places, this water is immediately dumped down the drain and wasted, but it doesn't have to be that way. Greywater can be a perfectly good source of irrigation water, or it could be used to flush toilets.

When you reuse greywater, you're getting a double use of your water. You use it once inside your home, and then you can use it again outside to irrigate your landscape. In dry climates or places experiencing drought, greywater is a very valuable resource. It can help keep landscapes lovely and productive, even during times of water shortages.

Join Laura Allen, the co-founder of Greywater Action, to learn about the basics of greywater systems. Greywater Action is an educational organization that teaches people how to reuse resources like greywater, as well as collect rainwater or have waterless toilets. Laura has also written several books about water reuse to take people through the steps to design these water savings.

In this free class, Laura will share with you how to get started reusing greywater, a very valuable resource, as well as teach the five steps for a successful greywater design.

This course clearly establishes costs and clarifies the essentials of greywater applications.

Im in to preserving whats left of the land and trying to revitalize it. Down to waste management areas and this is on track with the type of self sufficiency implementations that would help towards that direction.

I am already familiar with the concept and practice of greywater as a resource and it was still informative. It might be helpful to present actual quantities of water available from the various sources such as a typical load of laundry or shower etc. Also, in gravity fed applications, dosing siphons can provide a much better and even distribution of water throughout the system.
