Greywater - Using greywater in your garden
Watering your garden with greywater can be a safe and practical way to keep plants alive during the current climate.
There are at least two approaches to take. Either you can manage greywater to avoid the chemical and human health hazards or treat the greywater to remove these hazards.
Greywater treament systems can be quite expensive and may not be necessary if you take a commonsense approach to your household practices and the products you use in the house.
This section explains how to minimise the main hazards that can arise from inappropriate greywater use:
- Pooling of greywater, from too much use, can cause odours.
- Chemical damage to plants, soil structure and soil organisms.
- Over watering which leads to waterlogging as well as increased potential for runoff and subsurface leaching of pollutants.
- The spread of pathogens that cause disease.
