Fire Service. The population supplied and protected is 

 89,000. 



Following the rule in the American Civil Engineers' Pocket 

 Book (page 948), the plant capacity to be dedicated to fire 

 service is ^89, or 9.45 million gallons per day. 



The average output is 5.05 million gallons per day. The 

 amount of plant capacity dedicated to peak loads of ordinary 

 consumption, exclusive of fire service, is 70 gallons per capita, 

 equal to 6.22 million gallons per day. The total plant capacity 

 required for ordinary use, exclusive of fire service, is the sum 

 of these two items, or 11.27 million gallons per day. 



These estimates are made without regard to the actual 

 plant capacity, which may be somewhat less than the sum of 

 these items, because a part of the reserve for ordinary peak 

 loads is available also for fire service; or, on the other hand, 

 it may be greater because some growth has been anticipated 

 in construction. These figures mean that if a plant were provided 

 for fire service only, it would need to have a capacity of 9.45 

 million gallons per day, and a plant provided to supply water 

 for use, and with no provision for fire service, would need to
