Abstract

Grey water is the waste water generated from bathrooms, sinks, washing machines, and other kitchen appliances. Grey water is generated by human beings during their household activities can be recycled by treatment for activities like gardening, flushing etc. This grey water if not managed properly creates problems like health hazards, river water pollution and land pollution. Thus it becomes extremely necessary to have a proper waste/grey water management system. Grey water generated from residential area, commercial area, institutional area, and recreational area falls under waste water. There is an increase in grey water constantly due to increase in population and change in life style.
