Do you know about grey water? It is gently used water from your showers, bathroom sinks, washing machines, and tubs.
Greywater does not come in contact with feces from the toilet and/or washing diapers.
However, it may contain traces of grease, hair, food, dirt, and certain household cleaning products.
It has been estimated that over half of household water used can be recycled as greywater. Potentially, this could save hundreds of liters of water on a daily basis.
Component of a Grey Water System
There are two ways to create a grey water system that recycles your water.
The first one is diversion devices that simply carry Greywater from your washing machine or bathroom directly to your toilet or garden, without treating it.
The components are:
A simple flexible hose is used to divert greywater from its source to the garden.
The price of a diverter valve is around $30-40. When you install it and it allows for choosing when the water flows to the sewer and when it flows to your garden.
It is used for the diversion of grey water to your toilet. It does not allow the water to flow to your garden.
Some states in the U.S have not issued legal approval for using the closed-loop system yet, however, these policies are frequently changing so I would recommend looking into your state regulations.
The tank is used for storing the brunt of the outflow. This way, the grey water would not flood the garden.
It is important to remove the sludge from the surge tank after 5-6 months.
In addition, it should have an overflow device so that the excess water is diverted into the sewer.
They are an essential component of the diversion device, which is used to remove hair and other particles from the water. The purpose is to avoid clogging in the irrigation pipes.
Remember, filters need regular maintenance and cleaning. It is recommended that you replace the filter on a regular basis, I would suggest every 6 to 12 months.
A water pump is essentially useful and necessary for getting water to all parts of the garden – particularly if gravity is not on your side.
However, there are several designs for this and some that involve no electricity too.
You may also need a power source – meaning thereby that you need to get an outdoor powerpoint installed.
Grey Water Treatment Systems
The second way to recycle greywater is through the treatment system. This system collects and treats the water to different levels of hygiene and purity.
The different stages involved in the treatment of water are:
1. Solid filtration that involves hair and lint removal.
2. Removal of unwanted chemicals and pathogens such as bacteria, viruses, salts, and nutrients. This is either done through chemical treatment or with micro-organisms.
3. Disinfection by UV light or chlorination.
What is Next?
After treating water with the treatment system, you can use the water in toilets and washing machines. You can also use the water in your garden.
Moreover, if you do not have much garden to water and/or if you are not in need of water your garden in all seasons, still, this sort of treatment system is useful as you can use the treated water elsewhere.
How Much Will it Cost?
A basic treatment system would cost you around $3500.
If you want the “Class A” greywater treatment system, which is safe for treating the water to be used for watering plants that are intended for eating (however, not for drinking) will cost you around $10,000 to $15,000 – this also includes the cost of installation!
