Such an interpreta-tion in its fullest sense would involve a complete statement ofthe physical, chemical and biological properties of a sewage asindicated by the ordinary analytical results. It was shownthat the analytical figures usually obtained did not providesufficient information to permit of any such thorough interpre-tation. The problem was therefore somewhat simplified byfirst defining three groups of characteristics of a sewage andattempting to correlate them with the analytical features.These three general properties of a sewage may be briefly definedas follows:- The physical property of concentration refers simply to whatis ordinarily known as the strength of the sewage.
