Ecosan is a shortened term for ecological sanitation. It refers to a system of human toilet systems which separate solids and liquids at source, safely and in a hygienic manner without causing pollution; and uses the nutrient value contained in the waste for growing plants. Typical sanitation solutions have included the septic tank or simply a pit latrine. Both tend to pollute ground water and are environmentally unsatisfactory.
