b. Water Use

The Characteristics of water use that are important in the design of a water system include the
average-day demand, the maximum-day demand, the peak-hour demand, and the fire flows. The
average-day demand is used primarily for water resource planning. The maximum-day demand
is used to size the treatment plant, transmission lines, main pump stations, storage reservoirs, and
the main distribution lines that deliver water from one reservoir to another. The peak-hour
demands are used to size the distribution lines and booster pump stations that do not pump to a
storage tank. Fire flows are also used in sizing the distribution lines as well as storage tanks.
The average daily consumption is of importance for the management of the water system in that
it is used to estimate the total annual usage and detennine the adequacy of the raw water supply.

The highest annual volume of water used by the City occurred in 1994 with 903,000,000 gallons
being delivered. The average number of taps served by the City during the year was 2,967,
making the average-day demand 834 gallons per day per tap. With a population of 8,440, the
average per capita consumption for 1994 was 293 gallons per day, which is high. The monthly
water use for the past three years is shown in Figure 2.
