Re: Wastewater Engineering Analysis
Field Report for July 12 & 13, 1994
Dear Mr. Calvin:
Attached herewith is the report on our site inspection of the
proposed location for acceptable out-house sites. The three home
sites on ~the south side of Bird Creek are proposed to have septic
systems. The five home sites on the north side of Bird Creek are
proposed to have earth privy systems.
Sharon Whitlock:
No acceptable perc locations were observed in the field.
Recommendation:
1. The use of a holding tank located just south of the road in the
front of the house.
2. Move the well to the north of the house along Bird Creek to
meet the 100 foot setback requirement from well to holding
tank.
Dea Calvin:
A distance of 87 feet from well to septic was verified.
Recommendation:
1. Apply for a waiver on the 100 foot set back from septic to well
measurement.
2. Perform an adequacy test on the septic system.
Butch Wheeler:
A distance of 90 feet from holding tank to surface water and 10 feet
from holding tank to well were verified.
Recommendation:
1. Move the holding tank to the south next to the base of the hill
approximately 15 feet or apply for a waiver on the 100 foot
setback from holding tank to surface water measurement.
2. Move the well to the west of the house along Bird Creek to meet
the 100 foot set back requirement from well to holding tank.
Fritz Hayes:
Three test holes were excavated (see attachment). TH1 established
bedrock at 3.5 feet. TH2 established bedrock at 1.5 feet. TH3
established bedrock at an acceptable depth of 4.5 feet, a minimal
percolation rate of 80.0 minutes/inch was tested at this location.
Recommendation:
1. Move the privy to an area of 4.5 feet or greater to bedrock and
find a location which will have a minimal percolation rate of
60.0 minutes/inch.

Kathe¥ Hess:
One test hole was excavated (see attachment). TH4 established gravel
at an acceptable depth of 5.5 feet, a minimal percolation rate of
80.0 minutes/inch was tested at this location.
Recommendation:
1. Move the privy to an area of 4.5 feet or greater to bedrock and
find a location which will have a minimal percolation rate of
60.0 minutes/inch.
Rita Ea~le:
Two test holes was excavated (see attachment). TH5 established
bedrock at a depth of 1.5 feet. TH6 established gravel at an
acceptable depth of 5.2 feet, a minimal percolation rate of 35.0
minutes/inch was tested at this location.
Recommendation:
1. Move the privy to TH6.
Richard Tremble:
One test hole was excavated (see attachment). TH7 established
bedrock at an acceptable depth of 5.7 feet, a minimal percolation
rate of 23.3 minutes/inch was tested at this location. TH7 was
measured at 103 feet from surface water.
Recommendation:
1. Move the privy to TH7.
Dario Martinez:
Four test holes were excavated (see attachment). TH8 established
ground water at 4.5 feet. TH9 established ground water at 2.5 feet.
THi0 established ground water at 3.5 feet. THll established ground
water at an acceptable depth of 4.7 feet, a minimal percolation rate
of 4.5 minutes/inch was tested at this location. TH8 through THll
all fail to meet the 100 foot minimum setback from surface water to
privy. TH12 established a minimal percolation rate of 2.1
minutes/inch at a location on the hill behind the existing privy at a
distance of 113 feet from surface water.
Recommendation:
1. Move the privy to an area of 4.5 feet or greater depth to
bedrock on the hillside and maintain the 100 feet minimum
distance to surface water. The location will need to have a
minimal percolation rate of 60.0 minutes/inch.
