Subject: Percolation Tests and Design Recommendations
Onsite Sewage Disposal System, Proposed Francis Residence
Lot 1, Phase 2, Pilgrim Downs Subdivision
Eagle County, Colorado
Job No. 3158
Gentlemen,
E
O
C
As requested, we investigated subsurface conditions with respect to
installation of an onsite sewage disposal system (OSDS) at the subject
site. The purpose of our investigation was to determine subsurface
design parameters with respect to an OSDS system. The site is located
in Eagle County Health Department (ECHD).
SITE CONDITIONS - The investigated site is a 16 acre lot located in
a rural subdivision of Eagle County, south of Edwards, Colorado. The
location of the proposed residence, existing well, OSDS and percola-
tion tests are presented on Figs. 1 and 2. The slope at the proposed
disposal field area is 25% to the southeast. -The--driveway-is-below
rthe propose ie an wi require that the field be- a-minimumfofm 32,
feet-laterally above the crest of the roadcut. The ground surface has
a good cover of native grass and weeds. The disposal field site was
vacant at the time of this investigation with the exception of the
test pits. The well had been drilled to the southeast of the house.
PROPOSED CONSTRUCTION - A 5 bedroom residence is proposed a ndicated /
on Fig. 1. The-,s_ewage load from a 5 bedroom dwelling is 750 gallons
per day (GPD),`,-101� GPD with a 1:5 safety factor. This loading in-
cludes a garbage grinder and washing machines. --We-. recommend --water
saving devices be included in the construction of the homes. The resi-
dence will be served water from an existing onsite well located south-
east of the residence.
SUBSURFACE CONDITIONS - Subsurface conditions were investigated by
excavating 2 profile pits and three percolation holes at the locations
indicated on Fig. 1. Subsurface conditions encountered in the profile
nits consist of 1.5 feet of sandy clay topsoil, underlain to 5,feet by
sandv clay, underlain to 9,,feet by claystone bedrock. No free water
was encountered in the profile pits. The profile boring was checked
1 day after excavating and no water was observed.
Percolation tests indicate percolation rates of 40 to 60 minutes per
inch (MPI). The average percolation rate is 47 KPI. The results of
the percolation tests are presented on TABLE I.
2 -
RECOMMENDATIONS - Subsurface conditions indicate a "standard" OSDS can
be installed to serve the proposed residence. The installation should
include a minimum of 1500 gallons of septic tank capacity. There are
Xtwo 1000 gallon 2 compartment septic tanks mite, which we un-
derstand are to be installed. Because of the elevation of the resi-
dence, the 5 foot depth to claystone bedrock, and the driveway cut in
the vicinity below the proposed trenches, a pump-will-.be-required:,to
.access the disposal trenches We recommend a 1%3 -HAP:=pump-=-instal=led
-as indicated- on --Fig*•- 4. The 2nd septic tank will access--.the--lower
disposal trench: We recommend that the 2nd septic tank be connected
to the lower trench via a gravity outlet in the case of a power or
pump failure.
Using Table 5 of the ECHD regulation, 350 square feet (SF) of disposal
trench is required per bedroom or a total of,1750 SF -of disposal
trench. LWe recommend six 100 foot long trenches as indicated bn--Figs,.
2.and--.3.. The trenches should be installed at a depth of 6 inch`es into
the native soil on the low side of earh trench to maintain 4 feet of— _
suitable soil beneath the trenches. A minir-
�ed above the top of th. rave in lieu of serial--distributionl-j.�welb
recommend a "surge tank" as indicated on Fig. 5 to; allow: -flow Ito- eachv
of the trenches without saturating the top trench,.
With the -pump required to access the trenches, we request =a-25%-reduc-
tion in disposal field area based on dosing: The resultingwareais
'1350 SF,, or 450 lineal feet of trenqn.—Ve—recommend 5„trenches ',,90•'
feet in Jength.
,In lieu � of -gravel trenches, gravel -less systems - are ,possibl,ei: We
recommend the -"Infiltrator" system with pressure-distribution,for-a
gravel -less system. The Infiltrator is allowed a 40% reduction, -which
should may not combined with a dosing reduction, -we recommend a -total
reduction of 40% for pumping and the Infiltrator. The resulting area -
required°would be,1050 SF or 350 lineal feet of Infiltrator -We.
recommend a minimum of four 90 foot infiltrator trenches=.
If the owner is anticipating future finishing of additional bedrooms
in unfinished areas, we recommend the OSDS be constructed to handle
the additional loading. The installation of a properly sized OSDS to
serve future build -out can be cost effective. For greater than 5.
bedrooms, the septic tank will have to be increased by 250 gallons per
additional bedroom. Each additional bedroom above 5 bedrooms would "
require 350 SF of disposal field, or equivalent infiltrator area.
We recommend that the surface of the disposal field be seeded after
installation of the system. We recommend using a seed mix such as -a
"Foothills, Pasture, or Prairie" mixes available at local feed and
seed o
seres. These mixes do not require irrigation and develop a
growth 10 to 15 inches high. No lawn irrigation or sprinkler system -
should be installed above the disposal field.
The owner must realize an OSDS is considerably different from public
sewer services. The owner must be aware of and assume the responsi-
bility for continued maintenance of the system. The system is rela-
tively maintenance free, but the owner must have the septic tanks
pumped. We recommend the tanks be pumped on a regular schedule of
3
every two years. There are daily considerations, such as not putting
plastic or other nonbiodegradable material down the sewage disposal
system. Also, water use must be carefully monitored so toilets are
not allowed to run when seals malfunction. To illustrate the point,
it should be noted a running toilet will consume in excess of 1000
gallons per day if allowed to run. As the system is designed for 750
GPD, an excess 1000 GPD will irreparably harm the system and stress
the well.
We caution you against installation of a water softener. The high
levels of salt from a water softener and extra hydraulic loading is
detrimental to all OSDS. A separate drywell should be installed for
the backwash waste, if a water softener is installed.
LIHITATIONS - Our investigation, layout, and recommendations are based
on data submitted. If subsurface conditions considerably different
from those described in this report are encountered, we should be
notified to evaluate the affect of the changes on the proposed sewage
disposal system. If modifications to are recommendations are made by
governing Health Departments, we should be contacted to evaluate the
effect on our OSDS recommendations.
If there are any questions or i'f we can be of further service,
please call. tFG�Si

Lot 1, Phase 2, Pilgrim Downs Subdivision
Eagle County, Colorado
Job No. 3158
Gentlemen,
We observed the installation of the OSDS at the subject site on
October 5 and 14, 1991. We designed the system under our Job No.
3158, dated August 26, 1991.
On October 5, we observed the installation. The alternative which was
selected was the INFILTRATOR system with four 90 foot long trenches.
Although most of the installation was in conformance with the plans,
there were 2 items which needed to be changed which were: 1. the
lowest trench was to close to the top of the roadcut, and 2. the pipe
for the "pressure dosing" was missing from the infiltrator panels.
On October 14, we returned and found the pressure dosing pipe was
installed properly and the lower trench had been relocated to the east
as indicated on Fig. 1. Electrical connections were not completed on
October 14, but Mr. Brownlee called on October 16 and indicated the
electrical connection had been completed and the pump and alarm system
functioned properly. Upon completion of the backfilling of the
trenches, the field area should be seeded.
r'!e U'i`,.Acerctaiau t. a discharge of the backwash srom the water softener is
to be to the north of the residence and not into the OSDS.
If there are any questions, please call.
