AMOUNT OF SEWAGE PER CAPITA 117 



water as follows, the amounts being partly estimated and partly

Of this amount 4 gallons per capita was allowed for public uses. 



The amount of water wasted, that is, ignorantly allowed 

 to escape from the mains and negligently allowed to escape 

 from faucets and leaks, is very large. 



A very striking proof that the pumping records do not 

 show the amount of water used is furnished by one of the 

 towns in the Metropolitan District. All the water used in 

 the town was measured by a meter on the supply-main, and 

 every service-pipe has a meter. The works were but four 

 years old, had 18 miles of cast-iron mains, 376 services supply- 

 ing about 2300 persons, and, with the exception of the water 

 used for flushing mains, street-construction, street-sprinkling, 

 and for fires, all of the water used was measured by the meters 

 on the service-pipes. In 1893 the daily average amount 

 registered by the meter on the supply-main was 128,560 gallon?, 

 while the total recorded by the service-meters was 65,380 

 gallons. Allowing 2000 gallons per day for blowing-off pipes 

 and for fires, there remains 61,380 gallons, or nearly 50 per cent 

 of the whole consumption, unaccounted for. In Newton 46 

 per cent of the water pumped was not accounted for by the 

 service-meters, after making proper allowances for water not 

 so registered. In Fall River, during the same year, with the 

 most careful system of inspection to prevent waste, 37 per 

 cent of the water pumped jould not be accounted for. 



In West Orange, N. J., the water company buys all its water 

 by meter from another water company and then sells it by
