Wastewater is becoming more widely recognized as an asset to exploit rather than a liability to be treated and disposed of to the environment. It is virtually 100 percent recyclable and is a source of nitrogen, phosphorus and other agricultural nutrients; soil amendments and conditioners; biofuel oils; methane gas for heat and electric power production; and treated water for cooling, irrigation and potable human consumption. Wastewater is an ideal source for recycling because it is collected and delivered to water treatment facilities as sewage, thus taking advantage of the existing infrastructure and obviating the high cost of collection and transport that limits other types of product recycling.
