SUBJECT:Cohoe Subdivision Water Supply
(Glenn A. Huff)
Transmitted herewith for your review and comments are two sets of plans and associated
documents for the subject project. This is a proposed semi-public water system for Hr.
Richard Strutz. The existing cesspool, as shown on the engineers p~nt, is in the pro-
tess of being relocated. The new location will be outside of the 120' radius and either
on the north or south end of Lot 1 of the Subdivision. The explanations for protective
radii, around this well, are found on Page 5 of the engineering report and will be in-
cluded on the as-built plm~s prior to recording of this plat and after preliminary
review. Your approval is recam~nded.

PS:
The sewer system serving the house (It) on Lot 10 is actually m~ approved septic
tanL and seepage pit. Its location is shown as an existing cesspool.

ENGINEERING REPORT
Cohoe Subdivision
Water System for Lots I through l0
A. General
1. The system as designed will serve the ten lots in this subdivision
as shown on the attached drawings,
2. The system as designed will not be expanded.
3. There will be no industrial activity which will affect the requirements
of this water system,
4. The estimated daily water consumption assuming 75 gpd min. and 3.25
persons per residence and ten residences is 75x3.25xlO = 2440 gal/day.
This is the present and future requirement.
The capacity of this sytem is based on the peak demand computed as follows:
Assuming for each lot:
1. bathroom group with flush tank
2, kitchen sink
3. laundry tray
Total supply fixture units per lot = ll
For ten lots the load on the system in supply fixture units is llO.
With this load the supply demand is equal to 46 gpm for approximately
20 min., or 920 gal.
With the installation of one 82 gal. hydro-pneumatic storage tank with
2/3 effective volume for storage located on each lot the total storage
for this sytem will be 82x2/3xlO = 550 gal.
Required pump capacity 370 : 18..5 gpm
20
5. The source of water for this sytem will be the existing deep water well
located as shown on the plans. The well is drilled and cased with a 6"
casing to prevent ground water contamination. The top of the casing will
extend at least 12" above finished grade with no pit around the casing,
Finished grade shall slope away, from the casing in all directions. The
well will be equipped with a N.S.F. approved Williams Adaptor for
submersible motor pumps Model No, 603U and seal or approved equal.
2
6. All development in this area depends on wells for their water and the
acquifer which this well penetrates has proven to produce water of a
quality suitable for household uses. Prior to public use the water
from this well will be tested for quality.
A, Permafrost is not present in this area.
B. This is not a surface water source,
C. Purification is not anticipated or proposed.
D. Pressure will be maintained in the lines at all times by the use
of a submersible pump with a minimum rating of 24 gpm wi'th a discharge
pressure of 60 p.s.1, and a depth to water level of 200 ft, ~Jacuzzie
Submersible Pump No, 354D-T2 or equal), To minimize fluctuation in
pressures a hydro-pneumatic system consisting of one 82 gal. pressure
tank will be located in each res!dence, Pressure loss in the 2" main
at peak flow is negligible.
E. The distribution lines will be constructed with approximately 430~ of
2" Sch 40 PVC N.S.F. approved water pipe and fittings. Sergice connections
with a corporation stop at the main and a curb stop with service box
installed at the property line for each lot will be constructed as part of
this system using 3/4" Sch 40 PVC N.S.F. approved water pipe.
2. There are no special features in the distribution system.
3. The distribution system will be installed with a minimum of lO~ of
cover over the distribution lines,.
4, The system will be located in glacial till at the depth specified,
F. Water will be stored as outlined in 7D.
2. Fire protection has not been provi'ded,
G. Cost Estimates
Construction
Well with 6" casing - existing
430' of 2" Sch 40 PVC main at $4,50/ft,
*10 curb stops installed at $150 each
Submersible pump each
$1,935
1,500
600
~$~,'03'5'
2. Maintenance cost estimated to be $200 per year.
*~urb stops include service connection. Eighty two gal, pre~sure tank
to be installed by each builder as lots develop,
3
The following minimum distances from points of possible contamination
to ground water supplies will be exceeded:
1. Any contamination - exceeds 40 ft,
2. Sewers, septic tank, disposal fields exceeds 80 ft,
3. Seepage pits - exceeds 120 ft.

Dear Mr. Strickland:
Re: GAAB - Cohoe Subdivision Water Supply
The as-built plan for this project were forwarded via Mr. Cherry
of our Anchorage office by your memorandum of 5 October 1970.
Our previous letter concerning this was dated 10 August 1970.
We regret that we cannot approve these plans since we have no as-
surance as to what type PVC was used (we require NSF approval of
the type); we do not know to what depth the grout seal, if any,
extends; and we do not know the material used between the house
and curb stop.

Dear Mr. Strickland, ·
As requested b~. your memorandum of Oetober 27, I am submitting the additional
~ata requested by the State ~ealth ~ept. through your office.
As requested, a note has been added to the plans, that indicates 3/4" ~ype E
copper has been used between the curb stop and the house. All connections
·ade have been 3/4" Type K copper and all future connections will be made with
Type X copper.
All P.V.C. pipe used in this system was schedule 40 N.S.F. approved. A note has
been added to the as-built so' stating.
Th® well in this system was an existing well. There was no requirement for a
grout seal ia t~e plans or Specifications for this system andthe approval letter
did not require this item to be added.
I have checked wit~ local well etrillers, concrete suppliers, and Concret products
of Alaska, in regards to the above mentioned grout seal. None of the people
contacted are familiar with tais processors and did not know of any one who
had the required e~uipaent in the Anchorage area.
The ~aterial in this area is a dense,~ '~ve~., which Will preven~ perco-
lation of surface wa~er around the casing. T~ts casing,has been in place for
several years.
We are requesting approval of the system with out the grout seal.

and our Anchorage office) which forwarded the material used for the
water line and a satisfactory bacteriological test of last July of this
supply.
The PVC pipe used is of a type and make approved by the National Sanitation
Foundation and is satisfactory.
We note on the bacteriological water analysis form (Lab. No. 18637) that
a "distance to cesspool" is given as 90'. By copy of this letter we re-
quest Mr. Huff to verify this or to furnish us with the correct distance
since this cesspool may now have been moved.
Further, and as stated in our 28 December 1970 letter, we still require
a chemical analysis of this water.

SUBJECT: Lot 109, Cohoe Subdivision
Dear Hr. Adam~:
We have reviewed your situation in light of the interpretation of
the 40,000 Sq. Ft. -20,000 Sq. Ft. requirement contained in Section
18 AAC 72.030 of the Department of Environmental Consetwation Waste
Water Regulations. It is our finding that since you had ownership
of the lot on or before February 5, 1973 mid that you intend to
const~ct a private residence for your personal use, that this particu-
lar Section of the Waste Water Regulations is not applicable in your
case.
We would however advise you that of course all existing Borough
Regulations are ~n effect and are applicable in all cases except
where State requirements are more stringent.

Dear Mr. Strutz:
Re: Cohoe Subdivision Water Supply
2~%is refers ~o the plan~ specification sheet, and engineering report
by Mr. Glenn k. Huff~ P.E., which were forwarded to this office by
~r. Roil S~rickland's %o~ Greater z~mchorage Area Borough Health~ Department)
~namorandum of 31 July 1970. Also received were applications for
Review of Plans. }4r. Sgrickland's memorandum included info~aation
concerning protective distances, well ~o contamination areas.
We believe the expected water consumption will be nearer 100 gallons
per capita day than 75 but the system and piping are adequate in any
E~e~'ienca wi~h PVN wa[er pipe is somewhat limited in this state. We
reconnnend the use of Schedule 80 vice 40 for the type to be used. The
PVC must be approved by NSF hence under specifications, Water Lines
A.I.~ the "or equal" which follows "N.S.F." is not applicable and
must be deleted.
'l~ae service line between the curb stop and house must be 3/4 inch
copper to allow for thawing should freezing result. With this assurance,
and that NSF approved PVC will be used, and also that the chemical
and bacterial analysis Of ~he water conten~ is satisfactory, this
systera is approved for those features with which this Department is -
concerned.
Sincerely yours,
RAB:tbf
