Researchers from Texas A&M Study Gray Water As a Potential Water Source for Landscaping
Texas A&M University System personnel will be investigating the feasibility of gray water use for home landscape irrigation as a statewide initiative for conserving water resources. gray water is essentially “soapy” water left after tap water has been run through a washing machine or used in a bathtub, bathroom sink or shower and does not contain serious contaminants. Gray water for irrigation is already allowed in some southwestern states, including parts of Texas, with some restrictions. “Research results indicate that with minimum precautions water from our showers, bathroom sinks and clothes washers could be used to meet up to 10-15 percent of our overall landscape water needs.” said Dr. Calvin Finch, director of the Water Conservation and Technology Center in San Antonio.
