Water, its use and misuse, is one of most controversial issues landscapers must deal with today, especially for those working in the southwestern U.S. where water resources are limited. With new laws and regulations dealing with water changing all the time, it is imperative for landscape professionals to stay current on these issues or face the possibilities of fines, lawsuits or other legal problems.
For this reason, Leslie McGuire, the Educational Programs Director for the 2010 Landscape Expo, has dedicated 14 out of 47 seminars being offered to deal specifically with water use within the landscape arena. The Landscape Expo will take place October 6-7, 2010 at the Long Beach Convention Center from 9:00 a.m. to 2:30 p.m. daily. Seminars begin at 9:30 a.m.
Two seminars being offered deal with Graywater Systems and Rainwater Harvesting, two very hot issues facing professional landscapers. These courses will be taught by Daniel Wilson, MESM, president of Weldesign, Inc., a landscape design firm based in Santa Barbara, CA.
Wilson has a degree in Aquatic Biology and a Professional Masters degree in Policy and Management of Environmental Sciences with a technical emphasis in Biogeochemistry. He is a licensed landscape contractor, and the president of Wilson Environmental Landscape & Design. Wilson conducts workshops and teaches college classes in Landscape Construction, Irrigation Technology and Sustainable Landscape Design throughout California.
