Gray water is composed of recycled household water.
In urban areas, watering with gray water is a way to conserve water and still water your plants and garden vegetables. Gray water is water recycled from dishes or laundry. One of the major drawbacks of watering plants with gray water is that the water contains salt and other contaminates from detergents. Over time, these contaminates can build up in the soil and can cause a decline in the health of the plants placed in the soil. One way to remove the contaminates from gray water is to pour it through a filter. Does this Spark an idea?
