Hinsdale, IL (PRWEB) October 20, 2011
John R. Bauer, President of Water Harvesting Solutions (http://www.wahaso.com), will be speaking at the American Society of Landscape Architects’ (http://www.asla.org) annual conference on October 30, 2011, in San Diego, California. He will be joined by executives from ET Water and Landtech Irrigation Consultants to explain the processes behind sustainable irrigation.
Landscape irrigation is already restricted in many areas of the U.S. where drought and rapid population growth have created an urgent need to reduce municipal water consumption. But even regions with abundant rainfall and other water resources are anticipating future shortages of potable water. Using drinking water for irrigation can be seen as an extravagance that is unaffordable. "Water shortages put a lot of pressure on the landscape industry to not irrigate,” explained Bauer. “But even with water efficient landscaping and careful application, most plants still need some irrigation to thrive. The question is, how can we irrigate in a manner that is sustainable? Harvesting on-site water sources for irrigation is the sustainable solution."
Sustainable irrigation addresses the need to use water resources efficiently and decrease dependence on municipal water supplies. The process begins with the capture and treatment, or “harvesting,” of on-site water sources, which can include rooftop rainwater, surface stormwater, greywater, cooling condensate and more. Once collected, the water is filtered, stored and then treated to eliminate any potentially harmful pathogens. The next stage involves accurately determining the amount of water needed for irrigation day-by-day and zone-by-zone. The evapo-transpiration, (or ET), method of irrigation monitors real time weather data to calculate the precise water requirements for each irrigation zone net of rainfall, evaporation and transpiration of the plants. The final step in the sustainable irrigation process is the application of the harvested water. Highly efficient irrigation design may use zone layouts or varying delivery systems such as spray, drip or subsurface application.
Wahaso, ET Water and Landtech represent the experts in their respective fields on the topic of sustainable irrigation. Bauer has led Wahaso to be a leader in developing and implementing harvesting solutions for irrigation, toilet flushing and more. Mark Coopersmith, managing director of ET Water (http://www.etwater.com), is helping to bring innovative technologies to the irrigation industry that monitor and control water supply and demand. Landscape architect and managing director of Landtech Irrigation Consultants (http://www.landtechdesign.com), Jim Davis, is a Certified Irrigation Designer and “WaterSense Partner” with the Environmental Protection Agency.
Bauer, Davis and Coopersmith’s presentation was one of 90 sessions selected out of the 370 proposed to ASLA for this year’s conference (http://www.asla.org/2011meeting/). Harvesting On-Site Water Sources for Sustainable Irrigation, is session number A7, scheduled for 8:30 AM Sunday at the conference. Bauer et al will provide an overview of the topic and then revert to a panel format to address audience questions. The topic of sustainable irrigation fits in well with the association’s mission of careful stewardship and wise planning of natural environments and should prove to be a popular draw. The ASLA represents over 17,000 members and this year’s annual convention is estimated to draw over 6,000 registrants.
Wahaso is an integrated solutions provider of systems for harvesting and recycling rainwater and greywater in commercial and institutional buildings. Their engineers build custom systems that harvest rainwater, stormwater and greywater for irrigation, toilet flushing, cooling tower make-up and other uses. Multi-source systems range in size from thousands to hundreds of thousands of gallons and can save millions of gallons of municipal water annually. Integrated systems include pre-filtration, storage, sanitation, polishing and pressurization to meet output requirements. Custom controls monitor all system functions and connect with building automation and smart ET irrigation controllers. Engineering fees, installation assistance, warranty and operator training typically are included in system pricing.
Wahaso was founded in 2008 by John Bauer and the company’s Director of Engineering, Stuart Bailin. Mr. Bailin has over 30 years of experience in fluid systems engineering and construction. And while water harvesting for commercial buildings is a relatively new industry, the company has completed - or is in the process of completing - well over a hundred projects for commercial and institutional buildings across the nation.
