[greenyes] Residential graywater systems


Melissa Kelly asked:

Can anyone recommend information about residential graywater systems --
systems that would enable a resident to divert graywater (e.g., from
showers and laundry) to water the lawn? Are there examples of developers
who regularly incorporate these systems in their new housing developments?


IOBB is currently hosting an online seminar headed by Paul Totterdal entitled:
Waterharvesting : solution to water collection, filtering and recycling

Paul has an introductory paper and is responding to questions on a daily basis throughout this month. You must become a member to participate, but dues are nominal, based upon a small percentage of your monthly income. It is truly an internationally based operation, with many interesting discussions from participants in diverse locations, and dozens of potential forums to join.

Paul's concept of waterharvesting has to do with installing a dry creekbed with liner to hold water from many sources. Plants and vegetation clean up water in various ways, making it available for many uses, thereby reducing the need for pumping groundwater and diverting water from rivers and streams.

About the Author

I am a horticulturist of 20 years. I work in landscape based water recycling. I have developed a simple approach to stormwater and wastewater collection treatment and reuse called Waterharvesting. Waterharvesting is a landscaped solution to water collection, filtering and recycling.
Abstract The primary feature of this technique is a 'dry creekbed'. This is a bed of rocks, gravels, sands and soils which can be sealed from, seeping into, or open to the landscape profile.

A system of subsurface creekbeds is used to direct stormwater and greywater or any wastefluid to landscape growing areas, while at the same time filtering and treating the water to remove contaminants and then recycling the treated water for non potable uses.
