What types of grey water to avoid:-
Some concerns have been raised with the use of grey water. Try to avoid:
●Water from kitchens as it can contain levels of fat, food residue, and other contaminants
●Bathroom grey water as it can be contaminated with non-biodegradable soaps and other personal care products
● Water with laundry detergents and dishwasher detergents that are high in phosphates and other chemicals as they can have a negative impact on the environment when used as greywater
● Water used for washing dirty diapers and other sanitary products as it can contain human waste which poses health problems for the use of this grey water
However, many greywater systems can be designed to overcome these concerns and make use of the valuable resource that is greywater. There are many benefits to installing a greywater system in your home or building:
● Provides locally-generated water
● Lowers requirements for extracting water from local water systems
● Reduces impact on sewage and septic systems
●Is a means for recharging groundwater systems
● Reduces the energy needed to convey water through conventional systems

What is grey water?
Greywater, also known as greywater or graywater, is recyclable wastewater produced from activities such as dishwashing, laundry, or bathing. Grey water differs from black water which is wastewater used in toilets and designated for sewage systems. Greywater can be used for a variety of purposes such as
irrigation or toilet flushing and is collected from:
● Sinks,
● Showers,
● Bathtubs,
● Washing machines,
● Dishwashers,
In India, wastewater generation from all class-I cities and class-II towns is 38254 MLD and treatment capacity is 11787 MLD, which is about 30 % of total sewage. About 70% of wastewater remain untreated and discharged in water streams like rivers and ocean leaving them polluted.
Average domestic water consumption pattern:-
In urban India, about 48,000 MLD of water is supplied and on average a person uses 165 litres of water per day. The chart and table below show the breakdown of per capita domestic water use pattern.
CONCEPTS FOR GREY WATER REUSE
There are various methods that can be used for Greywater treatment right from simple low-cost devices that route greywater directly to applications such as toilets and garden irrigation, to highly complex and costlycadvanced biological treatment processes incorporating sedimentation tanks, bioreactors, filters, pumps and disinfection systems. There are a number of greywater systems commercially available, and may include one or more components including primary solids separation, oil and grease removal, filtration, aerobic biological treatment, coagulation and flocculation, and disinfection. Some of these systems are able to remove pollutants and bacteria from greywater and the better systems include settling tanks, biological reactors and sand filters, enabling the treated greywater to be stored until needed without adverse conditions occurring (like foul odours, corrosion, etc.) but the method which should be followed must be most effective and economic or in other words optimum in nature.
