In the developing countries like India, waste water management remains the most important cause for many pollution and disease spread due to poor sanitation. Grey water is the domestic waste water excluding toilet waste water gains attention in the present scenario for recycling and reuse. Application of this grey water after proper treatment can be put to many uses in urban areas thereby reducing the demand for fresh clean water. Treated grey water is well advocated in agriculture for crop cultivation. Of the total grey water generated in the country, 10% is contributed through kitchen waste water that accrues from households. Since this waste water is low in contamination, treatment through any methods is possible and feasible for reuse. Regarding the chemical composition, grey water is very less in nitrogen levels than sewage water. Unlike rainwater harvesting, grey water is not dependent on unpredictable cycles of monsoon and variability of rainfall and is therefore a reliable water resource. Further, the high nitrogen and phosphorus content that is harmful to aquatic life, when used in irrigation can make a good nutrient or fertilizer source.
