AS TO SERVICES AND METERS 



The detailed figures show considerable divergence of practice 

 with reference to the amounts of water that meters of all sizes 

 will handle, but the divergence with respect to the line of division 

 between f-inch and f-inch meters is much greater than else- 

 where. An interesting and profitable subject for discussion 

 would be the question as to whether it is better to use a f-inch 

 meter or a f-inch meter for service drawing from 300 to 1000 

 gallons per day. Such a discussion would tend to establish the 

 principles that should govern, and it might aid in reaching a 

 more logical and scientific method of determining the size of 

 meters required for various services. 



It is of course true that services are occasionally found 

 which require water at a certain rate, and where that rate deter- 

 mines the size of meter even though the total aggregate draft is 

 small; but it would seem as though, generally speaking, some 

 relation between the normal rate of draft and the size of meter in 

 the larger domestic services might be found. 



The New Orleans annual reports for the years 1913 and 1914, 

 George G. Earl, general superintendent, show the average daily 

 drafts of water by meter sizes. These with similar data col- 

 lected by the author for the Spring Valley Water Company a.t 

 San Francisco for the year 1916 are as follows:
