Greywater Harvesting

Greywater Harvesting

The greywater system allows homeowners to capture and reuse water in multiple projects around the home. These projects spawn a lot of curiosity in arid areas with limited water supply or engineering works that need a lot of water.   Greywater harvesting is applicable in commercial, residential, and industrial projects because it is reliable for seasons with a low water supply, and we only expect things to get better as the technology evolves and becomes more feasible for more extensive applications.

Most Important Things To Know About Harvesting Grey Water

Most people are worried about greywater because we are essentially using wastewater with many chemicals and toxins. It is normal to think about these things because we are using the water on things like plants, so basically, some of these chemicals will cycle their way back into our bodies. We will look at everything that goes into the process and how to customize your multi-stage greywater filtration system.

Properties Of Greywater

Only 70% of the water from household waste passes as greywater, and most of the water comes from the laundry, kitchen, and shower. The system does not use containing human waste, so basically, a regular harvesting system will only contain chemicals from the dishwasher, bathing lotions, and other solutions in the same space.

The main problem with reusing water is that the system does not know the difference between fresh and used water, hence the need for a greywater system to divert its content to a different channel, so it is rendered useless and goes to the municipal water treatment system. Reusing the water through greywater filtration solutions makes it easy to rid it of pathogens and chemicals that could cause harm to the garden, so do not try to bypass the process with a DIY setting.

Sources Of Grey Water

The regulations and rules about harvesting greywater are different for different areas, but the following are the common areas to source the water.

Wasted Warming Water

Most shower and tap systems will take a couple of seconds to warm up the water before it becomes hot. We turn on the water and let it run as we wait for it to get hotter, so the warm or cold one that runs off gets into the greywater harvesting system.

Bathroom And Bathtub

Greywater from these spaces is collected through a specially designed system to drain the water into storage to clean it off the harsh elements and then redirect it into secondary uses.


Laundry to landscape systems is another effective way of collecting greywater, especially when you do not use harsh chemicals like chlorine. We have a complicated system that will ensure all the water flows out to the right places and does not flow back in, get human contact or mix with other systems.

Reusing greywater is the best way to reduce waste and stress on your water supply after biological or physicochemical greywater treatment methods for businesses and establishments. A freshwater is a good option, but reusing it in multiple projects is the best way of making the most of your household water system.
