Recycling greywater is the act of using otherwise wasted water from drains in the home-with the exception of toilet water, AKA blackwater. An average homes wastewater is essentially greywater, wasting away up to 80% of sewage water or septic water into the ground or local water reclamation utilities. By recycling your greywater, you can reuse it to benefit you and your home in many different ways.
In many areas, local codes require that greywater be treated as blackwater and therefore are subject to state regulations concerning septic use. Check with the local building department before beginning any parts of this project.
Since storage of greywater can make it resemble blackwater in 24 hours, its best applications are used as direct contact with topsoil and used for irrigation. Soil bacteria quickly break down the waste and provide nutrients for plants. Biological water purification can work towards your benefit as well.
Plant Growth and Soil Fertility
Greywater supports plant growth in areas that may benefit from irrigation. The soil and decomposition microorganisms devour finer particulates of greywater and release nutrients into the soil as there bodies die and decay. Plants thrive on this growth.
The underground water supply or aquifer can be maintained at an environmentally safer way than direct expose to a septic tank. Without the use of natural organisms to transform the waste into nutrients and plants to accumulate those nutrients, wastewater percolates slowly back into the groundwater supply.
Reduce your Carbon/Water Footprints
During summer months when irrigation is at its highest; recycle your greywater over your trees. Just keep in mind contact with greywater before it has a chance to metabolize is not recommended so keep pets and kids away from greywater recycling systems and always wear gloves when handling any greywater equipment.
So long as you design your greywater recycling system so no human to greywater contact takes place, you’ll be safe. Always wear gloves, never reuse hoses and always wash your hands after use you can prevent any bacterial contamination. Do not apply to fresh veggies or fruit and avoid any contact with soil for 24 hours.
