Effect of Domestic Grey Water on Soil Quality System

Characteristics of greywater are highly variable; greywater amount varies from 50% to 80% of the wastewater volume produced by households. All types of greywater show good biodegradability in terms of COD: BOD ratios. The ratio of BOD/COD in greywater ranged from 0.31 to 0.71. Most countries apply the same standards to reclaimed municipal wastewater as they do to greywater. Reusing greywater (GW) for on-site irrigation is becoming a common practice worldwide. Alongside its benefits GW reuse might pose health and environmental risks. The current study assesses the risks associated with on-site GW reuse and the main factors affecting them. . Land application of greywater is likely to have environmental impacts which may be positive or negative. Greywater can contain plant macronutrients that may benefit plant growth. Conversely high levels of surfactants oils grease sodium and potentially pathogenic organisms may impact environmental and human health.
