PLAN FOR WATER SYSTEM
VASHON WATER DISTRICT
(By j. G. Eernissc, Engineer)

DcpIclluCI IL, IJGo
To the Commissioners
VashOn Water District No. 10
King Co.
VaShon, Washington.
Gentlemen:-
| have the honor to report to you
a Comprehensive Scheme or
Plan" for the development of a
water system for Vashon and the
surrounding community.
Area
The area Of this district is one
square mile, lying near the center
of vashon island with a portion Of
the area draining to the east and
the rest to the west.
Population
The population of the district
is about $50. Conditions are very
favorable for a substantial growth
of this district as soon as an a
abundant water supply is assured.
Present Water Supply
The present water supply is from
individual wells and few small
springs. Few in the district have
all they need during the dry
. months when water is most needed
and in most instances the supply is
unsafe and ordinarily the more
dense the population, the more un-
safe the water.
Organization Of District
Vashon Water District No. 10 Of
King Co. has been regularly or
ganized and established at a spec.
ial election held August 31st. 1925
at which time three commissioners
were elected. They are: Mr.. VIM
Garvin, Chairman, Mr.. P. M
Smock, Secretary, and Mr.. 7. Han.
sen. Alex Stewart is attorney for
the district and j. G.. Eernisse it,
engineer.
Funds Available
Five per cent of the assessed val
uation of the property within the
district is the limit of the indebt
edness of the district. The assess
ed value of the district is aproxi
mately $S0,OO0.O0. The general
bond issue for the water system
can therefore, not exceed $4,000.
Additional money for the diff
ferent portions Of the system will
be paid by the local Improvement
districts to be served within the
area of the district.
The proceeds from the general
bond issue are to be used for the
construction of the pnmping plant
and storage tanks and special as
sessment will have to be issued te
cover the cost of laying the mains
in the district.
Water Supply-Amount Needed
If all the services are metered,
100 gallons per capita per day may
be considered a reasonable al
lowance. Estimating each house
hold to contain four persons, 80
services (the number required tt!
serve the present homes) would re
quire: SOx4x100 or $4,000 gallons
per day.
Whereas it is estimated that moi
more than thirty will actually re
quire service at this time, which
means that it will be necessary to
supply only 10000 gallons per day
or 1-3 gallons per minute.
With good soil, an ample water
supply, paved highways, electric
lights and power rates, which will
decrease as the population increas
es, good schools, increasingly bet
ter ferry service, with growing
and expanding cities on each side
of the island, a growing poultry
business and the possibility of ex-
panding the district to wider
boundaries, it is reasonable to as
sumo that the population within
the boundaries will demand not
less than 100000 gallons per day
within the next Is years.
Sources of Supply
In seeking a water supply for
any community the three most es-
sential Requirements are:
/. Quality.
2. Quantity.
3. Cost.
There are three sources of sup
ply available to this district:
/. Wells.
2. Nettle Creek Springs.
3. Beall Creek Springs.
