What is grey water?
Greywater or sullage is domestic wastewater generated in households or office buildings from streams free of faeces, i.e., all streams except toilet wastewater. Sinks, showers, baths, washing machines, and dishwashers are all sources of greywater. Greywater is usually safer to handle and easier to treat and reuse onsite for toilet flushing, landscape or crop irrigation, and other non-potable uses because it contains fewer pathogens than domestic wastewater. Greywater may still contain pathogens from soiled clothing or cleaning the anal area in the shower or bath.
Can grey water be reused?
Global water resource availability is deteriorating. According to one report, water scarcity will affect 2.7 billion people by 2025, affecting one out of every three people on the planet. Reusing greywater has proven to be an effective solution to this problem, and wastewater reuse is also known as recycled or reclaimed water.
Advantages of reusing grey water:
· Using treated greywater for toilet flushing saves approximately 35% of drinking water.
· Using treated grey water saves the world from the scarcity of water.
· The use of greywater reduces demand on conventional water supplies as well as pressure on sewage treatment systems.
· Reusing greywater also reduces the amount of sewage effluent entering waterways, which can be beneficial to the environment.
Benefits of reusing grey water in ecological sustainable development:
· Freshwater extraction from rivers and aquifers has been reduced.
· Infrastructure such as septic tanks and treatment plants have a lower environmental impact.
· Reduced energy consumption and chemical pollution as a result of treatment
· Groundwater recharge
· Nutrient reclamation
· Natural purification in the top layers of soil preserves the quality of surface and ground water better than generated water treatment processes.
Can we use of grey water for toilets?
In certain dwellings, greywater recycling without treatment is used for applications where potable water is not required (e.g., garden and land irrigation, toilet flushing).
Greywater recycled from showers and bathtubs can be used to flush toilets. A system like this could save the average household up to 30% on water consumption.
Using grey water in toilets:
· Eliminates the risk of biological contamination.
· A cleaning tank is used to remove floating and sinking items.
An intelligent control mechanism that flushes the collected water if it has been stored for a long enough period of time to be hazardous; this completely avoids the problems associated with filtration and chemical treatment.
When you use a greywater system, you can save water, time, and money every time you do laundry or take a shower. It's a dependable, local, and drought-resistant water source that will keep your landscape safe from hotter summers and drier winters.
A greywater system can be as simple as a bucket that collects shower water or as complex as a whole-house system that includes pumps, filters, and treatment. The simpler the system, the lower the cost and the easier it is to maintain. All greywater must be applied subsurface and remain within the boundaries of your property (no runoff). A bucket to collect warm-up water from your shower is the most basic greywater system. Greywater buckets can be used to flush toilets or to water your garden. Another simple way to use greywater is to syphon it while adhering to local codes.
Benefits of grey water system:
· Greywater can help to reduce water and wastewater utility bills while also extending the life of septic system leach fields.
· It links us to our water supply, allowing us to better understand where our water comes from and where it goes. Being aware of our water supply encourages healthier product choices and participation in our landscapes.
· Using greywater in conjunction with water conservation, climate-appropriate landscaping, and rainwater harvesting reduces reliance on imported water and protects the urban watershed.
