CLASSIFICATION OF WATER SALES 



The greater part of the operating expenses and taxes could 

 be classified definitely into the three classes relating to source 

 of supply, distribution and services, but for some of the taxes 

 and general operating expenses there was no basis of classifica- 

 tion, and these items were distributed pro rata in proportion 

 to the items that could be directly distributed. 



The annual cost of maintaining the system and supplying 

 water may be classified as follows:
