110 AS TO SERVICES AND METERS 



for it of the estimates; the service is metered and thereafter 

 water to the extent of the estimate is furnished without charge, 

 but water in excess of the estimate is charged at the usual 

 rates, or perhaps at the manufacturing or wholesale rate. The 

 amount estimated is usually so many gallons per capita daily 

 for each person. Thus 75 gallons per person may be estimated 

 for a hospital or 15 gallons per person for a school, for school 

 days only. The following rules illustrating this method are 

 from the regulations of the water department of Columbus, Ohio. 



Free Water. Water will be furnished free of charge under conditions 

 made compulsory by the laws of the State of Ohio. 



Free Water to be Metered. All services to which water is supplied free 

 of charge must have meters. 



Maximum Allowed. The following average daily per capita allowance 

 of free water, based on the average number of inmates and attendants, 

 shall be granted as a.maximum free of charge to such institutions, to wit: 



Hospitals, 75 gallons per capita; asylums and other charitable insti- 

 tutions devoted to the relief of the poor, the aged, the infirm or destitute 

 persons, or orphan children, 40 gallons per capita per day. Police stations 

 and jails, work houses, fire engine houses, public bath houses and other 

 public buildings, parks and other public grounds, as may be estimated by the 

 Superintendent of the Water Department. 



Pay for Consumption above Maximum. All such institutions as enumer- 

 ated in the foregoing shall pay for all water used or that passes through 

 meters that supplies such institutions, etc., at the city meter rate, for all 

 consumption above such maximum. 



The Superintendent of the Water Department shall determine as 

 closely as possible the average daily population of such institutions for 

 the collection period, to the end that free water may be distributed as is 

 provided by law for such institutions, but that waste, and the use of water 

 for power purposes, may be prevented, save as payment therefor may 

 be made. 



For some public uses it is not practicable to meter the water. 

 Such uses are temporary ones, as, for instance, flushing sewers 

 through hose from hydrants, but in all cases it is possible to 

 make a more or less close estimate of the quantity of water 

 that is used. For instance, in drawing water from hydrants the 

 amount of opening and the pressures and the recorded time of 

 flow give a basis for at least a fairly approximate calculation.
