The number of people using the sewers was obtained by count- 

 ing the houses on the blocks reached by sewers and multiplying 

 by six. This gives 8400 as the number of people using the sew- 

 ers. Comparison was made with the amount of water used for do- 

 mestic purposes, which was estimated at 107 gallons per capita 

 per day, and which the writer believes is rather high, because some 

 of the data used to get these figures seemed somewhat indefinite. 



If 85 gallons be taken as the number of gallons of sewage per 

 capita per day, and 107 gallons per capita per day taken as the 

 amount of water used, the sewage flow is found to be about eighty 

 per cent, of the water consumption.
