Gardeners can actually use waste water to water your plant. Domestic grey water is the domestic waste water coming from baths, showers, dishwater, washing machines and also kitchen sink.
Of course not all grey water can be used to water your summer flowers and plants. Polluted grey water that contains chemical elements or oil waste would kill the plant and destroy the quality of the soil. Grey water that contains only some detergent waste or soap coming from sinks, bath and showers still can be filtered by the soils and compost. Therefore, watering the garden for couple of weeks during the summer time is enough to keep our garden healthy as ever.
Although prolonge use can cause some minor problems for the health of the plants, long term use is always possible with less consummation of soap and salts in your daily water consommation.
