such periods are 1.250,000 gallons
per day or more.
By building a dam to impound
water TO a height Of approximate
ly plus 80, or about twelve feet
above the present water surface
in your settled water basin, you
will secure a water storage of APP
proximately 400.000.000 gallons.
With this storage of water, your
watershed should yield 100000
gallons of water per day, which is
more than twice the amount you
can depend upon at the present
time, and should be able TO fur
nish your city with water for a
number of years in the future, un-
less the city should furnish water
to tho Naval Academy. Eastport
and West Annapolis This could
be done at the present time, as
Annapolis is using an average of
100000 gallons of water per day,
the Naval Academy is using 70Q,-
900 gallons. and Eastport would
use approximately 100000 gallons,
making in all 100000 gallons, II
meters should be installed. this
consumption would probably be
cut approximately 100000 gal
Ions, and the now impounding
reservoir would take care of the
growth in consumption for num-
Der OF years.
The estimated cost of the new
impounding reservoir is $123.395.
When the time comes that the
water stored in the new reservoir
would be insufficient to supply
Annapolis, the most available
source for increasing the supply
is from Bacon Ridge Branch,
which is the first large stream ~
ing west of the present water sup
ply. There is an old earth dam on
this branch about one thousand
feet above the Annapolis-C Chester
field road, located on the property
of Mr. Fritz Schoen. About one
hundred and fifty feet of this dam
has been washed out and this
could be rebuilt with a concrete
spillway fifty feet in width.
A pump house with an oil en-
CINE and centrifugal pump OF l.
100000 gallons daily capacity,
could be built adjacent to this
dam and pump the water stored
behind this dam over the ridge a
distance of about 5000 feet TO the
top of the slope of the watershed
draining into the existing supply
From the top of the ridge an eigh-
teen-inch vitrified pipe could he
Laid for a distance of approx
mately 1900 feet to the n a est
water course leading into the
present water supply.
The cost of such a dam. pump
house, machinery and pipe line. is
estimated to be $f01 Zoo, exclusive
of the cost of land. water rights
and rights-of-way for the pipe
line. While this is less than the
cost of the inpounding reservoir,
We do not recommend this at the
present time, as the cost of land,
water rights and rights-of-way
would be considerable, and the
cost of pumping every million gal
Ions into the present supply
would be about fifteen dollars.
This cost capitalized at six per
cent. represents $3.50 in capital
expenditure. and three months
pumping would wipe out the DIFF
ference in cost regardless of the
land. wafer rights and rights-of-
way.
An additional reason for build-
ing the large impounding reSer-
yoir on the stream from which the
present supply is taken. rather
than going 10 Bacon Ridge
Branch. is that if the present dam
is not raised, an auxiliary pamp-
ing plant would have to be install
led to lift the water from the pres
ent dam into the publication
works whenever the water falls
below the crest Of the present
spillway. With The higher i'm
pounding reservoir, ninety per
cent. of the water IN the reser-
voir would be available and low
by gravity through the puriilca-
lion works
Looking Sill further into the
future. when the daily consamp-
ton of Annapolis viii have passed
three million gallons per day, you
can build a large impaunding
