Gray Water

When we shower or do the dishes we produce gray water which is water that contains soaps and/or detergents. Usually, there is only one tank to accumulate gray and black (sewage) waters but it is possible to have a separate tank for the gray waters. It is however, not recommended to dispose of any soapy water in the Bay. Phosphate, which is often present in detergent, disturbs the nutrient balance in the water. This increases the algae growth and contributes to the eutrophication of our Bay (as well as any sewage discharge). To prevent this from happening use phosphate free soap or natural alternatives.
