Subject: Percolation Testing, Lot 20, Teller Springs Subdivision, Garfield
County, Colorado.
Dear Mr. Villiere:
As requested by you, Hepworth - Pawlak Geotechnical performed percolation testing at
the subject site on July 8, 1994. The findings of our work are presented in this report.
Three percolation test holes were excavated and soaked by others prior to our site visit.
The hand dug holes are located in the bottom of backhoe pits. The percolation test
holes are located approximately fifty feet east of the subdivision road and on the north
side of the existing drive.
Gravel alluvium soils were exposed in the bottom of the pits. The holes were cleaned
of loose soil prior to our testing. The percolation test results are summarized in
Table I.
If we can be of further assistance, please do not hesitate to call our office.
Sincerely,
HEPWORTH - PAWLAK, GEOTECHNICAL, INC.

Re: I.S.D.S. Design Review
Dear Tim;
This letter is in response to your request to have Jerome Gamba & Associates, Inc. review the
Individual Septic Disposal System (I.S.D.S.) design which was given to you by the Garfield County
Building and Sanitation Department.
The proposed septic system is located at 0280 Lariat Lane, Teller Springs Subdivision, Lot 20. The
percolation test was performed by Hepworth-Pawlak Geotechnical, Inc.. We will use a percolation
rate of 14 minutes/inch.
It is our understanding that the 'Barn' (partially framed house(under construction)) is being built at
this time and the 'Log House' will be built in the spring of 1995. The 'Barn' and the 'Log House' are
both two bedroom structures using a garbage disposal and an automatic clothes washer. Both
structures will each have individual systems serving them.(see attached map received from Tim
Villiere).
Barn & House Design: According to Garfield County regulations, assume two (2) persons per
bedroom using an average daily flow of 75 gallons/person/day. Therefore:
(2 bedrooms) x (2 people/bedroom) — 4 people
(4 people) x (75 GPD /person) — 300 gallons/day (average daily flow)
Maximum D ' Flow: Maximum Daily Flow is 160% of the Average Daily Flow,
therefore:
Max Daily Flow — 160% x(Average Daily Flow)
(1.5 x 300) — 450 Gallons per day (GPD)
The absorption area for a normal gravel-type leach field is calculated using the formula (a factor of
1.6 is used for a residence with a garbage disposal system and an automatic clothes washer):
Area — 1.6 x O Q = Maximum daily sewage flow m 450 GPD
6 t — average soil percolation rate — 14 min/in
therefore Area — (1.6) x (450) x
6
Area — 538.8 s.f.
Conservatively, 540 s.f. of bottom surface area will be used as the absorption area for the a normal
gravel -type leach field.
According to the State Department of Health, when the "Infiltrator" leaching chamber is installed in
a bed configuration, a reduction of 40% in the size of the absorption area is allowed. When installed
in a trench configuration, a reduction of 50% is allowed. You may need to contact your supplier
and inquire if they are within the specified parameters to meet this area reduction calculation.
Therefore, If in the Trench configuration as discussed:
Area of "Bio Diffuser" units required — (0.60) x 540 — 270 s.f.
Therefore, the number of "Bio Diffuser" units required is:
Area of one "Bio Diffuser" unit — 17.9 s.f.
The number of "Bio Diffuse? units — (270 s.f.) / (17.9) — 15.08 units (use 10 units)
The "Bio Diffuser" units shall be laid in two (2) trenches of equal length (50.67 ft.). The
"Bio Diffuser" units will have a minimum 6f 24" cover over the entire trench. The "Bio Diffuser"
trenches will be laid along existing contour lines. According to Garfield County Building and
Sanitation Department the minimum horizontal distance between the 'Bio Diffuser' units is 6 feet.
According to Garfield County minimum requirements, the minimum septic tank size for a two
bedroom design is — 760 gallons.
All components of the septic system shall be installed in accordance with Garfield County Building
and Sanitation Department codes and meet all minimum horizontal distances and manufactures
specifications.
It is our recommendation that the septic tank be pumped annually to prevent the build-up of floating
solids and sludge. Failure to do so will result in solids entering the leach field, causing the leach field
to fail.
If you have any further questions regarding this design please contact us.
Sincerely yours;
JEROMEGAMBA& ASSOCIATES,Inc.

INDIVIDUAL SEWAGE DISPOSAL SYSTEM
OPERATION AND MAINTENANCE
The following tips and suggestions are intended to increase the useful life of your engineered
sewage disposal system and to prevent disposal system failure due to neglect and abuse.
MINIMIZE THE LIQUIDS
Wastewater that enters the system can be minimized by practicing water conservation
practices within your home. The less wastewater you produce, the less wastewater there will
be to treat and dispose.
1. Repair leaky fixtures. Check the toilet by dropping food coloring dye in the tank
and see if it shows up in the bowl prior to flushing.
2. Wash clothes only when you have a full load.
3. Take short showers instead of baths. Don't turn on the shower all the way and
turn it off while lathering.
4. Install and use water saving fixtures and devices in your bathrooms, laundry
rooms and kitchens.
5. Do not let the water run while washing, shaving, brushing teeth, rinsing
vegetables, dishes, etc. Use a stoppered basin where possible.
6. Provide adequate drainage around the engineered system area to divert surface
runoff from higher ground during storms or winter snowmelt.
MINIMIZE THE SOLIDS
Septic systems are "anaerobic" treatment systems. Digestion of solid materials is very slow
and requires air or "aerobic" conditions to "disappear ". The less material you put into the
system, the less often it will require pumping. A good rule to follow is:
"Don't use your septic system for anything that can be disposed of in some
other way"
1. Avoid using a garbage disposal. Throw out scraps and other garbage with the
trash.
2. Collect grease in a container rather than pouring it down the sink.
g. Minimize the disposal of paper products into the system. Nondegradable items
such as disposable diapers, sanitary napkins, tissues, cigarette butts and paper
towels are especially harmful to the system.
ISDS Maintenance
Page 3 of 3
Dosing Tank or Pump Station:
To inspect Oa losing tank, follow the same instructions for the septic tank. However,
there shout ioot be a scum layer or sediments inside the tank. Check to see if the
water level markings are consistent on the side of the tank. Variability indicates that
the siphon or effluent pump is not operating properly. If the water level is near the top
of the markings, wait for the siphon or pump to operate and watch for problems. The
siphon has an overflow pipe in which the effluent will flow out of the tank by gravity.
Should this be occurring, have the tank pumped and check the siphon openings to see
if they are plugged.
Filter Mound or Trench:
Check the observation tubes regularly. Standing water near the same elevation as the
natural soil surface (or higher) may be an indication of trouble.
Look for seepage or excessive wetness near the base of the filter mound or trench
area.
SUMMARY
A general inspection of the septic tank, dosing tank (or pump station), filter mound or trench
area should be made each year. These inspections are best made during the wet season of
the year. If these items are not routinely inspected, solids can carry over into the disposal
areas from the septic tank and clog the system resulting in system failure and health hazard
risk.
•
ISDS Maintenance
Page 2 of 3
4. Only three things should go into the septic tank:
Human Wastes;
Toilet Paper; and
Water.
6. Ordinary household chemicals (bleaches, detergents & soaps) will not hurt the
bacteria in your system when not used in excessive amounts.
6. DO NOT DISPOSEOILS, PAINTS,THINNERSJR OTHERTOXIC LIQUIDSINTO
YOUR SYSTEM.
A SEPTIC TANK ADDITIVES
Advertised chemical additives, bacteria, enzymes, etc. do not help solids breakdown in the
septic tank and should not be used to reduce the need for pumping the septic tank.
REGULAR INSPECTIONS
Septic Tank:
To inspect the septic tank, remove the manhole cover at the inlet end of the tank. Use
a shovel to push the scum layer away from the side of the tank and estimate it's
thickness. If the scum layer is 12" thick or more, arrange to have the septic tank
pumped immediately. Replace the cover and wash off the shovel and your hands.
For an average 3 or 4 bedroom residence, the pumping interval for the septic tank is
usually between 2 and 4 years. Annual inspection of the septic tank should become
part of your overall home maintenance routine.

Re: I.S.D.S. Design Review
Dear Tim;
This letter is in response to your request to have Jerome Gamba & Associates, Inc. review the
Individual Septic Disposal System (I.S.D.S.) design which was given to you by the Garfield County
Building and Sanitation Department.
The proposed septic system is located at 0280 Lariat Lane, Teller Springs Subdivision, Lot 20. The
percolation test was performed by Hepworth - Pawlak Geotechnical, Inc.. We will use a percolation
rate of 14 minutes /inch.
It is our understanding that the 'Barn' (partially framed house(under construction)) is being built at
this time and the 'Log House' will be built in the spring of 1995. The 'Barn' and the 'Log House' are
both two bedroom structures using a garbage disposal and an automatic clothes washer. Both
structures will each have individual systems serving them.(see attached map received from Tiin
Villiere).
Barn & House Design: According to Garfield County regulations, assume two (2) persons per
bedroom using an average daily flow of 76 gallons /person/day. Therefore:
(2 bedrooms) x (2 people/bedroom) = 4 people
(4 people) x (76 GPD /person) = 300 gallons/day (average daily flow)
Maximum Daily Flow: Maximum Daily Flow is 160% of the Average Daily Flow,
therefore:
Max Daily Flow = 160% x(Average Daily Flow) =
(1.5 x 300) = 450 Gallons per day (GPD)
The absorption area for a normal gravel -type leach field is calculated using the formula (a factor of
1.6 is used for a residence with a garbage disposal system and an automatic clothes washer):
Area = 1.6 x O It Q = Maximum daily sewage flow — 450 GPD
6 t — average soil percolation rate = 14 min/in)
therefore Area = (1.6) x (450) x 114
5
Area = 638.8 s.f.
Conservatively, 640 s.f. of bottom surface area will be used as the absorption area for the a normal
gravel type leach field.
According to the State Department of Health, when the "Infiltrator" leaching chamber is installed in
a bed configuration, a reduction of 40% in the size of the absorption area is allowed. When installed
in a trench configuration, a reduction of 60% is allowed. You may need to contact your supplier
and inquire if they are within the specified parameters to meet this area reduction calculation.
Therefore, If in the Trench configuration as discussed:
Area of "Bio Diffuser" units required = (0.60) x 640 = 270 s.f.
Therefore, the number of "Bio Diffuser" units required is:
Area of one "Bio Diffuser" unit = 17.9 s.f.
The number of "Bio Diffuser" units = (270 s.f.) / (17.9) = 16.08 units (use 16 units)
The "Bio Diffuser" units shall be laid in two (2) trenches of equal length (60.67 ft.). The
"Bio Diffuser" units will have a minimum of 24" cover over the entire trench. The "Bio Diffuser"
trenches will be laid along existing contour lines. According to Garfield County Building and
Sanitation Department the minimum horizontal distance between the 'Bio Diffuser' units is 6 feet.
According to Garfield County minimum requirements, the minimum septic tank size for a two
bedroom design is = 760 gallons.
All components of the septic system shall be installed in accordance with Garfield County Building
and Sanitation Department codes and meet all minimum horizontal distances and manufactures
specifications.
It is our recommendation that the septic tank be pumped annually to prevent the build -up of floating
solids and sludge. Failure to do so will result in solids entering the leach field, causing the leach field
to fail.
If you have any further questions regarding this design please contact us.
