The company keeps a record of the amount of water supplied to the city each month by means of Venturi meter measurements. The consumption naturally varies according to the season, being considerably greater during the winter than during the summer. The average consumption for the entire year at the present time is at the rate of about nine million gallons per day. In designing sewage works, however, the flows during the dryer portions of the year are what control the necessary size of the works. If the higher flows during the winter months are excluded the average consumption during the last two years may be taken as about 9.0 and 8.5 million gallons per day respectively. During the last five years meters have been gradually introduced and this has materially lessened the consumption. When the meter system has been extended to cover all services the consumption will be still further reduced. On the other hand, the increase in wealth and changes in the character of the houses will tend to increase the legitimate use of water. The present consumption of water for the purpose of sewage disposal may be taken as 8.4 million gallons per day, or 75 gallons per capita daily for the entire population of the city. It may be fairly assumed, moreover, that the amount of water consumption will increase in the same ratio as the population. Of course not all of this public water supply appears at the mouths of the sewers. Only about 89 per cent. of the population is provided with sewer connections, and more or less water is lost by use in boilers, by evaporation from lawns, etc. For purposes of calculation, however, i...
