Abstract
A drain water system includes a plurality of containers (,) within a building,for receiving respective drain waters differing in degree of contamination. A plurality of building,having such containers share a main drain water conduit leads to at least two stations (,) for receiving the respective drain waterd of differing degrees of contamination. Adjusting apparatuses (including, for example, pumps,) sequentially discharge the containers depending upon their degree of drain water contamination. During a certain time period, drain waters of the same degree of contamination will be discharged into the main drain conduit and will then flow to a specific station.
