High Capacity Greywater Reuse System

Abstract

Introduction: Due to the increasing need of reducing utility costs there is a growing interest in reusing "greywater" in landscape irrigation. Greywater is the return water flow of washers, bathtubs, showers and lavatory sinks. Wastewater from the toilets and kitchen sinks are excluded from greywater. Thus greywater does not have a very high organic loading and requires little or no treatment before it can be used for garden and landscape irrigation. The reuse of greywater greatly reduces the water needs of a family. It also reduces the energy required to pump and pressurize the lines that deliver the water. Perhaps even more significantly greywater reuse reduces the capacity needed in both the sewer lines and sewer treatment plants. The use of greywater instead of a diminishing groundwater resource reduces the guilt factor of those who enjoy having some shade, lawn and vegetables even though they are living in a arid environment.
