Based on an agreement between the City and Thermo, Thermo will have an
average day demand of approximately 1,280 gpm, or about 1.84 mgd.
Because of problems the City is having in reading water meters and correlating
metered data, it is unlikely the City wilJ have the capabilities of implementing
metered rates before the 1995 irrigation season. Problems include faulty meter
installation and computer hardware and software difficulties. The City's policy is that
the irrigation season is not the time to bill water customers for the first time based
on metered usage. City policy is that metered rates will not be implemented until
very late 1995 or early 1996 (at the earliest). Therefore, 1995 projections have
assumed the historical average per capita demand of 310 gpcd. Projections for 1996
and later assume the 225 gpcd demand, as a result of metered rates being
implemented in early 1996.
Future water demands based on an average per capita demand of 310 gpcd
in 1995 and 225 gpcd for the years 1996 and later, the population projections
summarized in Table 2-2, and the watet demands of Thermo are tabulated in
Table 2-6.
(2) Annual Average Demand. The annual average demands listed in Table 2-6
were calculated by multiplying the average day demands by 365 days per year. For
leap years, the annual average demand is based on a 366 day year.
(3) Maximum Month Demand. The maximum month demand will occur
during June, July, or August, depending on the temperature and monthly
precipitation. It is during these months that lawn irrigation is at its highest levels.
In addition, these months will be one of Thermo's peak periods because of power
demands created by air conditioners.
To calculate the maximum month, the Water Service Plan recommends the City's
average daily demand be assumed to be 2.1 times the average daily demand for
31 days. For Thermo, it was assumed the power-generating and thermal-use facilities
will require an average 2.0 mgd for 31 days.
(4) Maximum Day Demand. To calculate the maximum day demand for the
City, the Water Service Plan reco=ends a ratio for maximum day to average day
demands of 3.0. This ratio was used to calculate the values shown in Table 2-6.
For Thermo's maximum day demand, a consumption rate of 2.66 mgd was used
for the power-generating and thermal-use facilities based on the stipulations of the
agreement between Thermo and the City.
