Greywater systems are an amazing way to conserve water in an energy-efficient manner. Here are some of the best greywater systems for homes.
7 Best Greywater Systems for Homes
Water conservation is very vital. Since 70% of the entire universe is covered with water, you may ask, why should we conserve water? Besides, it’s a natural resource, and it is readily available. Water is renewable, but not all of it is drinkable. Well, fresh water is a limited resource. Only 2.5 percent of all water is freshwater.
A significant fraction of water in the water bodies is saline water. It thus must go through desalination to be fit for use. Desalination is a process that takes a lot of efforts and resources. Water can be scarce especially during the dry seasons. Thus, with the prevalent drought, water shortage is inevitable and water conservation has become necessary. Installing a greywater system for homes is one of the best ways to conserve water.
There are numerous ways to conserve water. But here, we are going to focus on how installing the grey water system in homes can help reduce water usage and look at the seven best greywater systems for homes.
In addition, bottled water consumption has grown rapidly developing the following cons of drinking bottled water. In the United States, an average person is estimated to use around 40 gallons of water per day to bathe and to do laundry. This water doesn’t have to go down the drains. Greywater systems for homes are thus becoming pretty handy.
So, what is a greywater system?
Greywater recycling system is a technology used to collect the water already used for other activities, clean and plumb it back for reuse.
Greywater sometimes called greywater includes water used for bathing, and washing clothes excluding sewage. Grey water is relatively clean and has not come into contact with human toilet wastes. Since sewage and kitchen water has relatively high organic loading, water from these sources is considered to be blackwater.
Grey water system treats the domestic wastewater and plumbs it back to reuse for other purposes like flushing the toilet, laundry, lawn and in landscape irrigation and more.
The water should be treated to very high standards to make it safe for reuse. You should ensure that it does not get contaminated with anything including cleaning and personal care products.
Grey water system is a system with numerous benefits. Besides reducing the wastewater entering the sewers, greywater can also help you reduce your water usage by around 50% and consequently cut your water bills by almost half.
Isn’t that cool? You may be wondering how greywater systems work, where you can get them from and which ones are the best for homes. In this article, we will help you answer some of those questions.
So, how do greywater systems work?
A greywater recycling system runs the grey water through a filtration process. The process helps reduce the existing scum and solid particles and sends it back for reuse.
The system treats or disinfects the water to different levels of purity. The process involves:
- Filtration or removal of solids such as lint and hair.
- Removal of unwanted chemicals including salts and nutrients and pathogens by use of either chemical treatment or micro-organisms.
- May also include disinfection by UV light or chlorination.
That way, it does not pose a threat to the environment. Different greywater systems vary in size and price. The grey water system cost ranges from affordable and straightforward to complicated and expensive mainly used for commercial purposes. Let’s look at some of the best greywater systems residential purposed.
List of Greywater System Technologies
Here are the seven best greywater systems for homes:
Bucket for your greywater
One of the best greywater systems that you can freely use is a bucket system. It is a system that uses a siphon method to collect and distribute greywater before it goes down the drain into a sewer or septic system. It involves collecting water from the rinse cycle of a washing machine or water from the shower.
On the use of bucketed greywater, there are no restrictions or approvals necessary. It is suitable for use in a washing machine, toilet flushing, and irrigation of lawns, gardens and outdoor pot plants. Manual bucketing involves small volumes of greywater and is thus considered low risk.
It results in minimal soil contamination and runoff to the neighboring properties. Lifting heavy buckets regularly can result in health complications.
Greywater Diversion Device or GDD
The Greywater Diversion Device is a process that involves directing greywater from a waste pipe directly into the garden to be used in sub-surface irrigation. The water is used for irrigation only.
A GDD consists neither of storage nor treatment apart from filtering out of larger particles that would lead to system clogging over a period. It is a device that incorporates an overflow system or a valve that helps divert the greywater back into the sewer if this is closed.
Gravity system is yet another greywater water system for homes. It involves diverting the greywater directly from the feed pipe to a drip line or a sub-surface irrigation system in the garden.
It only works in instances where the inlet is a few meters above the outlet, and may still lack sufficient pressure to push the water through longer lengths of dripline effectively. It may, therefore, result in somewhat patchy watering.
Pumped systems involve the use of a small pump to push the greywater through the irrigation system. It is a system that typically combines four components including:
- Some filtration process which removes larger particles in the water as it flows into the system.
- A small surge tank which helps cope with any sudden inflows of greywater for example, when draining the washing machine, and builds up sufficient volume for the pump to work.
- A pump which is used for distribution of the greywater directly into a sub-surface irrigation system.
The pumped systems are usually designed in two sizes including for single fixture or a whole-of-house system. The single fixture is used in laundry and is generally mounted on the ground with a 50mm inlet or on a wall. A Whole-of-House system, on the other hand, is installed underground with a 100mm pipe that feeds water from all showers, bath, and laundry. Since greywater can smell is left to stay for more than 24 hours, a greywater septic tank used is not a storage tank.
Some of the largest systems only have around 600mm diameter. Greywater system cannot be used to build up a volume of water. Some diversion devices are used to pump out all the water when the surge tank is filled.
Some larger tanks hold the water until the tank is filled and then pump it out all at once. It is an approach that allows the pump to work more effectively and pumps a larger service area. Thus, the plants grow better when they receive larger drink less often since it boosts root growth.
Packaged systems are easy to install and use
A packaged system is one of best greywater systems for homes. They are easy to install and use though they require electricity to work. They are self-contained and can be installed either indoors or outdoors.
Greywater Treatment System (GTS)
Another greywater system is a GTS which is more complicated than Diversion System. Besides filtering out the lumpy bits, it improves the quality of greywater from showers, baths, and laundry to a level where it can be used for surface irrigation, in laundry or toilet.
You need a permit before installing the GTS system plus a regular servicing regime. The water from a GTS that has been disinfected is pumped into a second larger tank used for storage. It can be used for surface irrigation or a sub-surface system.
Greywater irrigation systems
You can also use greywater spray irrigation systems. Though not recommended because of increased risk of exposure to people, the risk can be minimized if the greywater is treated to a higher level.
The greywater should be distributed under pressure so that surface spray devices can maximize droplet sizes, plume and throw height. It helps minimize water loss that can occur via evaporation and thus maximize plant use of the greywater.
