ALTERNATE PROCEDURE 71 



mum rate) is applied to the first 60,000 gallons of water per annum 

 drawn from each service. If cubic feet are used, the amount 

 is divided by eighty, and the result to the nearest even cent 

 is added to the domestic rate per 100 cubic feet, and the increased 

 rate is applied to the first 8000 cubic feet per annum used from 

 each service. In connection therewith, a minimum rate must be 

 established. This minimum rate may be about $3 more than the 

 computed service charge. This double procedure of loading the 

 rate for the first quantity of water sold from each service and of 

 establishing a minimum rate will accomplish in a rough way the 

 general purpose of the service charge. It is less satisfactory 

 because it is less fair as between the various small consumers 

 drawing quantities of water that will be affected by it. It is 

 as fair to the works and to the larger consumers because the load- 

 ing of the first quantity of water sold by the method described 

 will produce a sum nearly equal in the aggregate to that which 

 would otherwise be directly charged for the service. 



The Committee further recommends that where the same 

 works supply water in different services under conditions which 

 impose substantially greater relative expense in one or more 

 such services as compared with others, by reason of high service 

 pumping or otherwise, that it is just and equitable that dis- 

 criminations be made and that for water sold in such districts 

 the additional cost may be approximately ascertained and an 

 added price may be charged for water sold in such districts. 



For example, to one of the schedules as drawn above might 

 be added the words: 



For all water sold in the high service district the charges 

 shall be - - cents per 1000 gallons (or per 100 cubic feet) greater 

 than those in the above schedule. 



The Committee recommended that statistics of sales of water 

 by meter be classified in the following form. (The actual 

 statistics of the Belmont, Mass., water works, from the annual 

 report for 1916, probably the first to be published in the recom- 

 mended form, are filled in.) 



This form shows all the underlying data. From them the 

 amount of water that would be sold under each of the three
