In this study the object has been to learn what changes have takenplace in the consumption of water per capita after two-thirds to three-fourths of the services have been metered, as is the case in the MetropolitanWater District. The table on page 204 shows the changes in the use ofwater per capita in the cities for which records have been obtained in whichthe percentage of metered services in 1920 is substantially greater than 75per mid in which a sufficient number of years has elapsed af
