same time he was careful to point
out that negotiations with the
Washington Suburban Sanitary
Commission to supply the city's
water will continue no matter
how the referendum vote goes.
Getty officials are primarily in
terested in getting an adequate
water supply. at the cheapest
cost" said Mr.. MARYLAND.
In reference to the city's sup
plying its own water from the
Potomac, the city manager said
that the water revenue figures
are based on the minimum con-
sentative estimates of population
growth and per-capita daily con
sumption whereas the supply de-
signed for the new system is bas-
ed on maximum or peak" fig
ureS.
Beginning in 1858 when con
struction would be completed,
water revenue is based on 68 gal
Ions per capita daily use, increas-
ing at the rate of one gallon per
capita until 1867 when the high
of II gallons per capita will be
reached. This is below the 40
gallons per capita daily use which
is the national average.
Population growth estimates
are stopped at 1878 at a peak of
10000 as compared to today's IT,
600. Obviously population and
consumption will continue to
grow after these points but city
officials hope to be on the safe
side with these low estimates.
On the other hand, the national
average of 40 gallons per capita
daily use and high of 10000
population was used to figure the
supply necessary.
BY this means, the new water
system, according to Mr.. Mark
land, will definitely show a profit
which if allowed to accumulate
over the years would reach ST..
100000 by 1897.
This surplus could be used to
reduce the water charge, pay off
the bond issue, improve the sys-
tenn or on general improvements
to the town, according to the cit
liens wishes, the city manager
said.
These figures were gathered to-
gether during a years study by
the city staff, Gilbert Associates,
engineers, and Thacra Grant &
Company, financial advisors who
specialize in municipal affairs.
All maintenance and operating
costs, reserve funds, and payment
of interest are included in the
estimated figures.
The proposed system will in
clude: the Potomac River intake,
filter plant, clear water basin,
high pressure pumping station,
24-inch transmission line, addi-
tional storage capacity and i'm
provements to the distribution
system.
1t will be designed to meet the
needs for the next Is years but
so constructed that additions may
be easily made in the future as
the demand increases due to ad-
ditional consumers.
The filter plant, to reduce in
itial investment will be designed
for four million gallons daily,
while the pumping main from the
Potomac to the city will be sized
for eight million gallons daily,
the maximum possible future re-
quipement, since a pipe line is not
expandible.
Reservoir capacity of two mil
lion gallons will be added, and
additional storage may be con-
structed as the demand and rev.
enue increases.
The pumping main will follow
state and county highways, to re-
duce right-of-way costs, and to
pick up consumers outside the
city, thus increasing revenues.
At present Rockville is using
100000 gallons per day with an
average of 100000 gallons being
bought from the WSSC and the
rest supplied from the city's 38
wells. WSSC has never guaran-
