What are the environmental risks associated with reusing Grey Water?
Soil or plants can process many of the contaminants in Grey Water if the system is not overloaded, including organic material, nutrients, salt and sediment. Nutrients can even be beneficial in moderate concentrations, for example, on lawns but not on native plants. Some Grey Water contaminants are not capable of being treated or degraded in the soil. Principal among these is salt, which can comprise up to 30 % of some laundry detergents and can cause soil degredation.
