Current Trends and Regulations for Water Reuse in Irrigation

摘要

Water scarcity and water quality issues across the country are increasing the demand and acceptance by consumers for the use of recycled water. Recycled water is used for landscape irrigation, mostly for golf courses, but also for schoolyards, parks, athletic fields, cemeteries, nurseries, roadside vegetation, and some residential areas. There are no federal regulations regarding reuse but beginning in 1980 the EPA has published guidelines on reuse, which they upgrade every 12 years. The latest EPA guidelines were published in 2012. States in arid regions like California and Arizona, and states in areas with water supply issues like Florida have regulations on reuse. This paper will highlight the new 2019 Water Action Plan initiated by the EPA.
