Course Description: Natural wetlands such as marshes, swamps and bogs have long been known to protect water quality. Constructed or artificial wetland systems mimic the treatment that occurs in natural wetlands by relying on plants and a combination of naturally occurring biological, chemical and physical processes to remove pollutants from water. As of 1999, there were more than 500 constructed wetlands in Europe and 600 in North America. Constructed wetlands are a less energy intensive and more environmentally sound way of treating wastewater and conserving potable water. A small (20?EUR??,,????'?????<???EUR? x 20?EUR??,,????'?????<???EUR? x 4?EUR??,,????'?????<???EUR?) constructed wetland can clean all black, gray and other runoff water for the average home or small business. Water harvested from homes and small businesses including black and gray water, rainwater /stormwater and other runoff water (such as irrigation) can be cleaned using constructed wetlands. This water can be used for flushing toilets, sub irrigation and other uses. The demonstrated effectiveness of constructed wetlands for wastewater treatment provides useful lessons to create buffer zones for various types of contaminated water. Constructed wetlands not only reclaim water but provide needed habitat for wildlife. Even a small one (20?EUR??,,????'?????<???EUR? x 20?EUR??,,????'?????<???EUR?) will serve as a lush oasis, attracting birds, butterflies, toads and other animals. This presentation will concentrate on the first single-family home constructed wetland in southern Nevada, which was completed 12 years ago. This wetland has been regularly monitored since then and has shown excellent filtering capabilities. Two larger constructed wetlands, part of the school grounds and science projects in the Albuquerque, New Mexico School District, have had similar success and will also be discussed. Biography: M. L.
