200 FIXING METER RATES 



and with a consumption at the present time of 7 million gallons 

 per day, equal to 155 gallons per capita. 



A few of the larger manufacturing services only are now 

 metered. 



From a consideration of the above data and comparison of 

 the city in question with some of the others that seem to be 

 more or less similar to it, the following rough estimate is made: 



On the manufacturing services there are already 27 meters, 

 the records of which are available, leaving only 5 for which 

 estimates must be made. There is little to guide in estimating 

 the probable intermediate and domestic sales per meter and the 

 average for the data given above is used. Made up in this way, 

 we have: 



Gallons 

 per Day. 



Manufacturing uses records, 27 meters, actual 



records 774,ooo 



Five others estimated to range from 8200 to 16,000, 



averaging 12,000 60,000 



288 intermediate meters estimated to average 



1750 gallons 504,000 



7680 domestic meters estimated to average 159 



gallons 1,220,000 



Total estimated daily sales 2,558,000 



After meters have been in service for some years 

 and all leakage that can be stopped has been 

 stopped until the system is brought to the 

 average tightness of completely metered systems, 

 the unaccounted for water would probably 

 amount to 130 gallons per service daily, a total of 1,040,000 



Total probable daily consumption, when com- 

 pletely metered, but on basis of last year's 

 population and business 3,598,000
