Effects of Reclaimed Water on Highway Plantings, Soils, and Irrigation Equipment

摘要

The use of reclaimed wastewater for highway landscape plantations was studied. The objectives were to determine reclaimed wastewaters effects on soils, landscape vegetation, and irrigation equipment. Literature and field studies were performed. Five test sites using tertiary treated reclaimed wastewater and two potable water control sites were used. Soil and vegetation and aesthetic analyses were performed. Tertiary treated reclaimed wastewater has no adverse impacts on soils, plants, aesthetics, irrigation equipment, water quality or public health if properly used. A set of guidelines was developed to assist highway workers in determining whether or not reclaimed wastewater should be used in highway projects.
