GIRDWOOD WATER SYSTEM REPORT
PREPARED BY: Anchorage Water & Sewer Utilities
September ~ 1979
GIRDWOOD WATER SYSTEM
HISTORY
The earthquake of March 27, 1964, caused the original site of
the community of Girdwood, adjacent to the Alaska Railroad and
Seward Highway, to subside below the level of high tides in the
nearby Turnagain Arm. This rendered the area unsuitable for
continued occupancy and resulted in the establishment of the New
Girdwood Townsite which was platted by the State of Alaska
Division of Lands in October, 1964.
To provide the new townsite with water, the Corps of Engineers
constructed a well in January, 1965. The well is eight inches
in diameter, approximately 80 feet deep, and has 16.4 feet of
screen assembly. The Corps of Engineers estimated the pumping
rate at 350 gallons per minute. Presently there is a 5 h.p.
submersible pump with a rating of 74 gpm in the well.
The well and well house, a ten-by-ten foot frame structure with
electric heat, are located in the center of a 200-foot radius
well site reserve in the northwest corner of the intersection of
Alyeska Avenue West and Ski View Road. Approximately 1,000 feet
of two- and three-inch galvanized water main runs south down Ski
View Road from the well to the Girdwood Fire Station. The depth
and exact location are unknown.
Prior to unification in 1975 there were only five customers
hooked to the water system. Billing was handled informally on a
verbal basis by the City of Girdwood treasurer, and revenues
were approximately $183.50 per month. Except for occasional
freeze ups that required thawing, the only expense was for
electricity to operate the pump and heating unit. Subsequent to
unification when the system became the property of the Munici-
pality, all billing ceased until mid-1978o
The delay in initiating billing primarily resulted from legal
questions involving liability of the Municipality for the system
and potential regulatory problems. These issues have not yet
been completely resolved; but due to large expenses for pump
repair and thawing in 1978, the Municipality initiated a monthly
fee schedule for customers connected to the system (Assembly
Resolution 78-32, approved April 11, 1978)o
There are presently eight customers on the system being billed a
total of $350 per month. This is based on a rate of $10 per
month for commercial and residential units. These revenues go
into the Girdwood General Fund. The existing system also
benefits another six properties that could connect and provide
an additional $60 to $100 per month in revenues. Routine
expenses, which are largely for an electric bill and some
cursory maintenance by the Municipality, are approximately $150
per month. Extraordinary maintenance cost approximately $6,600
for the last 12 months.

HISTORY (Con't)
Historically, there have been problems with both the well and
the main. The pump and wiring recently had to be replaced, the
pressure tank quickly becomes waterlogged, and the main freezes
almost every winter. These problems generally result from a
combination of infrequent maintenance and an inadequate design.
GENERAL
There are two water utilities other than the Municipal system in
Girdwood/Alyeska; Alyeska utilities which is certified by APUC
and the Inlet Company water system which is an unregulated
system operated at no charge to the users by the Developer,
Inlet Company, of the subdivision. The remainder of the area is
served by small domestic wells° Refer to the attached map for
the location of these'two water systems, the New Girdwood
Townsite water system, and the Anchorage Water & Sewer Utilities
sewerage system.
Water production is presently quite limited in the Girdwood area
and not adequate for fire protection due to the low yield wells,
small mains~ and lack of storage° The presence of two streams,
a high water table and frequent precipitation appear to indicate
that domestic water supply will not be a major problem as the
valley develops. However, a coordinated water resource develop-
ment and storage program will be necessary to insure an adequate
supply for fire protection. These pressures will grow as the
permanent population, base and property values increase. The
Girdwood sewerage facilities plan predicts an average yearly
population of 4,500 by the year 1996o
PROBLEMS
It has become increasingly evident that a decision is necessary
on the future of the Girdwood water system.
Administratively it is undefined which Municipal department is
responsible for operation and maintenance of the system. By
default the Anchorage Water & Sewer utilities has taken the lead
in insuring that the system will function at a minimal level.
Unfortunately, due to an inadequate budget which resulted in
part from a total lack of revenues, there often were insuffi-
cient funds to cover expenses for emergency repairs and thawing°
Customers were not billed for water service during a three-year
period because the Municipal Attorney's Office stated there
would be regulatory problems with the APUC; as it would be
necessary to file for a certificate and prepare a tariff°
Girdwood Water Sys~m
Page 3
PROBLEMS (Con't)
Billings were finally initiated because of the deficit budget
and a revised opinion that the APUC would not interfere as long
as there was less than ten customers. This still remains a
potential problem; as there have been requests from other
property owners to connect to the system.
The Girdwood water system does not have chlorination which is
required by the State. This and the poor reliability of the
system could put the Municipality into an undesirable legal
position.
ALTERNATIVES
Three alternatives for resolving the problems with
the Girdwood water system follow:
1. Give the system t6 a user cooperative.
Upgrade the existing system to meet the requirements of the
Alaska Public Utilities Commission and the Alaska Department
of Environmental Conservation for domestic level service.
Expand ~he existing system to provide domestic/fire service
to a large portion of the remaining unserved area in Girdwood
with eventual acquisition of the other two water systems.
The first alternative is the result of Assembly Resolution 78-32,
approved April 11, 1978, which resolved "that the Municipality of
Anchorage will assist Girdwood in setting up a users' water
cooperative." Under this scenario the system could be given to
the user cooperative "as is" for operation and maintenance. The
Municipality would be relieved of responsibility for the system
and there would be no capital expenditure and O&M costs for the
Municipality°
The system could probably be operated more economically by those
directly benefited with a vested interest in the system
operation. As in the case of the former City of Girdwood prior
to unification, volunteer help would be readily available on a
24-hour per day basis if the need arose.
The second alternative would provide a reliable level of domestic
service to the customers. The necessary capital cost for
replacement of the existing 2- and 3-inch galvanized main,
rehabilitation of the well, and the addition of chlorination
equipment would be approximately $65,000.00. By constructing a
six-or eight-inch ductile iron system, which is more economical
than a three-inch copper system, the possibility of providing
adequate fire flows would exist if the source of supply was
expanded at some later date.
Girdwood Water System
Page 4
ALTERNATIVES (Con't)
State grants could fund approximately 40 percent or $26,000.
Regular operation and maintenance of the system would cost
approximately $1,000 per month. Extraordinary maintenance should
not be necessary for a number of years.
Excluding debtservice costs and special assessments, it would be
necessary to charge approximately $30 per month for domestic
water service° This figure could drop slightly as more customers
connected, but any substantial increase would necessitate
additional capital expenditures for one or a combination of the
following:
1o Increasing the capacity of the well.
Adding storage.
3° Constructing an additional well.
If it is no~ feasible to levy assessments, then an additional $10
per month would be necessary to cover debt service costs. These
projected user rates also do not provide for filing with the
Alaska Public Utilities Commission to become certificated and to
obtain an approved tariff° This process could cost in excess of
$50~000.
The third alternative would provide a unified reliable water
system for much of the valley but may be resisted by the
populace after the recent experience with the sewerage system and
because adequate ground water is generally available.
This project could easily be divided into phases with inter-
connection of the two other systems into the Girdwood system
being accomplished first. The second phase could be acquisition
of the private systems, the addition of storage capacity, and
construction of an additional well for increased reliability and
fire protection. The last phase for the immediate future could
be extension of the system south to the Girdwood wastewater
treatment facility water well.
The capital costs for new facilities are definable, but the cost
for acquisition of the other systems is questionable and could be
prohibitive if the owners either oppose Muhicipal involvement or
desire to take advantage of the situation.

$910,000
$605,000
Only the local share of the south extension could be assessable;
as the remainder is for loop ties and storage capacity, leaving
approximately $660,000 in capital costs to be recovered through
user rates which equates to a revenue requirement for debt
service of 9pproximately $5,000 per month at 7% for 20 years°
More reliability and additional fire protection will be gained,
but this alternative does not provide for the upgrade of the
other utility systems which from all indications are poorly
constructed and undersized°
Alyeska utilities presently charges a residential customer
approximately $14 per month° The additional debt service and
operation and maintenance costs of Alternative 3 could more than
double this rate to approximately $30-$35 per month assuming 400
customers° Even if fire insurance rates went down somewhat,
there may be a reluctance by customers to change the status quo.
RECOMMENDATION
The Anchorage Water & Sewer utilities recommend Alternate No° 1
for a number of reasons:
The Administration previously recommended and the Assembly
approved that a users' water cooperative be established as a
permanent solution for water service.
A large amount of money will have to be spent for upgrading
if the Municipality retains the water system, eventually
resulting in higher user rates ($30-$40 per month).
Girdwood Water Sys!~m ~-~
Page 6
RECOMMENDATION
Con't)
The operations and maintenance costs will be higher if the
Municipality retains the system. Even if maintenance is kept
to 'the absolute minimum, labor and the various administrative
overheads for the system will be costly. Few economies of
scale are available even with the Girdwood wastewater
treatment facility nearby.
Successful expansion cannot be predicted as the other systems
and populace may react negatively, especially as water is
generally available in quantities sufficient for a single
family dwelling°
In summation, the system and customer base are just too small to
absorb the costs of regulation by the State and administration by
the Municipality. The end result of retaining the system would
in all probability be a large deficit and or prohibitive rates
for water service.
