TREATMENT AND REUSE OF GREY WATER, AN INTEGRATED APPROACH TO HOUSEHOLD WATER IN PCMC AND NATURAL STREAM PROTECTION

CIVIL ENGINEERING

Fresh water unavailability is big problem which is going to be faced by whole world now a day. Fresh water unavailability can be classified in two categories first it can be because of unavailability of fresh water and second it can be because of mismanagement of fresh water. India is a country which fall in later category. Previous year population density was very less which was supporting the management of waste water but increasing population leads to unavailability of site where grey water can be poured. It was either at household level or community level. Adverse situation leads to policy method to manage waste water in some other way. They decide to collect waste water from household and treat it centrally. Waste water from household carry mainly 2% of solid in it rest is water, reflect on the fact that it is too much dilute. There is a principal in treatment industry that “dilution never results into economic treatment” so there should be effective measure on treatment of waste water at their origin. Per capita demand of water can be reduced by reusing by a proposed design of waste water in secondary activities like flushing, gardening etc. This project explain how PCD water can be reduced by reusing of waste water in secondary activities like flushing and gardening by proposed plumbing design. waste water can be managed more efficiently, we need to treat grey water at household level. It can be done by root zone technology which is most convenient, economic and best way to treat for its reutilization.
