GENERAL
As requested, Colorado Geoscience and Design, Inc. has investigated the subsurface
conditions at the subject site. The purpose of our investigation was to evaluate subsurface
conditions presented in Colorado Geoscience and Design, Inc.'s report and design an Onsite
Waste Treatment System (OWTS).
The Percolation Test and/or Soil Profile Pit Observation and the Onsite Waste Treatment
System design shall be submitted to the appropriate county for permits.
SITE CONDITIONS
The site is located at 587 WELD COUNTY ROAD 7, WELD COUNTY, COLORADO.
The location of the site, percolation tests and proposed OWTS are presented in Figure 1.
The general topography of the site slopes approximately i% to the east. The vegetation at
the site consists of native trees grass and weeds. The weather was warm and clear at the
time of the investigation. Free groundwater was not encountered.
• The soil treatment area shall be at least 100 feet from all onsite and off -site domestic
water wells.
• There are no anticipated construction -related issues, nor were there difficulties encountered
during the site evaluation.
• There are no current public records available from the health department.
• The proposed soil treatment area is not located in a flood plain.
PROPOSED CONSTRUCTION
A warehouse for a business is proposed at the site as indicated on Figure 1. It is our
understanding 4 people will be employed for 8 hours per day 7 days a week. The base sewage
loading for 4 people is 15 gallons per person day for a total sewage load of 6o gallons per day
(GPD). We do not anticipate any proposed land use changes in the near future that may
impact the new system.
• _
SUBSURFACE CONDITIONS
Subsurface conditions were investigated by drilling one profile test hole and three
percolation holes and a soil profile test pit as indicated on Figure 1. Subsurface conditions
encountered consist of stiff, slightly sandy clay to 6.5 ft., overlaying claystone to g ft. Soil in
the soil profile test pit consisted of silty clay to 8 ft. Percolation rates ranged from 6g to 120
mpi (minutes per inch). The average percolation rate was 103 mpi.
RECOMMENDATIONS
An engineered, infiltrator chamber trench system shall be installed in the silty clay. The
OWTS shall be base on a Long Term Acceptance Rate (LTAR) of 0.15 gallons/sq. ft. /day, a
design flow of 6o GPD plus appropriate design factors. Based on these design parameters,
the soil treatment area utilizing Quick 4 infiltrator chambers shall consist of the following:
• Twenty five (25) chambers are required in a single trench (See Figures 1 through 4 and
Calculations Work Sheet).
• Three inch (3") diameter perforated PVC pipe shall be suspended from the top of the
chambers and shall run the full length of each row. The pipe shall have two rows of 1/2"
diameter holes drilled at 2 ft. on center with a 600 offset.
• The maximum depth of the chambers shall be 30 inches. A mound may be required over
the chambers to divert flow from the soil treatment area.
• Effluent to the distribution laterals shall be uniformly allocated.
The system requires a minimum of 1-1,000 gallon two -compartment pre -cast concrete septic
tank. The top of the septic tanks to final grade shall be a maximum of 4 feet. If
the distance is greater than 4 feet an engineered tank is required.
NOTE: All tanks shall be approved by the Colorado Department of Public Health and
Environment (CDPHE). Please refer to the following web site for CDPHE approved (OWTS)
septic tank manufacturers: https;//ww •v.colorado.gov/pacific/cdphe/septicapproval
Observation pipes shall be installed at the end each row of the field and a drainage berm to
divert surface water away from the surface of the OWTS. We recommend the individual
sewage disposal system be installed as indicated on Figures 2 through 5.
Effluent lines placed beneath roadways shall be encased in larger pipe to prevent damaging
them. The pipe sleeve shall be Schedule 40, PVC that is 2 inches larger in diameter than the
effluent line. The encasement shall extend 10 feet beyond the edge of the road in both
directions.
LIMITATIONS
This study and OWTS design was based on accepted industry standards and state and
county guidelines. Subsurface conditions were based on observation at the time of the field
investigation.
In any soil investigation it is necessary to assume that the subsurface soil conditions beneath
the drain field do not vary greatly from the conditions encountered in our field and
laboratory testing. Our experience has been that at times soil conditions do change and
variations do occur and may become apparent during the installation of the OWTS.
Groundwater levels can be expected to fluctuate with varying seasonal weather conditions
irrigation usage for lawns and other circumstances.
Our investigation, layout, and recommendations are based on data submitted. Site soil
conditions encountered may appear different from the test borings as presented in this
report. Colorado Geoscience and Design, Inc. should be notified if the subsurface
conditions observed during the time of construction differ from the descriptions in this
report to evaluate the effect of the changes on the proposed OWTS or if there are any
changes in the location of the OWTS. Due to the variables such as individual usage,
maintenance practices, soil conditions, groundwater fluctuations and climate no warranty
express or implied is given to the life and performance of the OWTS.
The owner/builder is responsible for all regulations and requirements
regarding OWTS installations. This office must approve the OWTS installer
before work begins on this system. Failure to utilize an installer approved by
this office may nullify this design.

Operation and Maintenance of an Onsite Waste Treatment System
How an OWTS Works
Sewage contains bacteria and viruses that may cause diseases. Properly treated sewage prevents
these harmful organisms from entering the air we breathe, coming in contact with humans and
pets animals and insects, and polluting groundwater. Because the treatment of sewage is
important, the installation of your On -site Waste Treatment System (OWTS) is regulated by
state laws.
Your OWTS treats the sewage right on the property. Most OWTS have two parts, a septic tank
and an absorption field. The septic tank is the most important part of the system. Sewage and
waste water are piped from the home directly to the septic tank. Once in the septic tank, this
sewage undergoes a natural biological process called digestion. During digestion, naturally
occurring bacteria and enzymes act on the solids in the sewage, changing many of the solid
particles into liquid and gas.
Heavier particles that are not changed into liquid or gas settle to the bottom of the tank and
form sludge. Lighter particles form scum that float to the top of the liquid. The septic tank is
designed with tees and baffle so the sludge and scum stay in the septic tank, while the liquids
and gases drain off.
The absorption field (also called drain field, leach field or leach bed) is a bed that is configured
in various ways utilizing different types of applications (pipe placed directly in contact with the
ground, imbedded in rock or encased in chambers) to treat effluent from the tank.
The size of the absorption field is based on two things:
The percolation rate or the ability of the soil to absorb liquids. An engineer's soil test
determines the percolation rate which is based on how many minutes it takes one inch of
water to percolate into the surrounding soil.
a And the daily flow of sewage from the house. The daily flow is estimated from the number
of bedrooms in the house.
Operation and Maintenance of the System:
1. Control the amount of water discharged into the system. Your system is designed to handle a
predetermined amount of water. Larger volumes of water discharged into the system will stir
the contents of the septic tank and cause sludge and cum to flow out and clog the absorption
field. To control the amount of water discharged into the system you should:
a Repair any leaking faucets or running toilets immediately
Divert run-off water from roofs eaves and downspouts and foundation drains away from the
absorption field.
To illustrate the point, it should be noted a running toilet would consume in excess of 1O00
gallons per day, if allowed to run. As the system is designed for a specified amount of water, an
excess l000 GPD loading could irreparably harm the system.
2. Use normal amounts of these household products:
a Soaps, detergents, bleaches and drain cleaners
a Waste water from a home water softeners, spas, or pools may cause a slight shortening of
the life of the absorption field because the extra volume of the water that is used. Salts form
the softeners will not harm the septic system.
O There are many chemical products for sale that claim to improve the digestion process in the
septic tank. With the proper care and maintenance, the system should function well with
the added chemicals.
3. DO NOT dispose of these items into your system:
O Household items such as Kleenex, tampons, sanitary napkins cigarette butts, coffee
grounds, egg shells, oily waste or grease from cooking, paper towels, newspapers, wrapping
paper, rags, disposable diapers, and bones. These materials do not decompose in the septic
tank.
• Materials such as string acids, and photographic chemicals. These materials may upset the
biological process the needs to take place in the septic tank.
O Latex paint, waste water from pottery or sheet rock mud. These materials remain in
suspension in the septic tank, and then flow into the absorption field clogging the pores of
the soil.
4. Regularly remove the sludge and scum form the septic tank.
O A list of licensed septic tank cleaning companies can be obtained from the county health
department or from on-line sources.
5. Keep the absorption field in good condition.
. o Mow the grass and weeds growing on the absorption field regularly.
▪ Because of the very shall depths of the installation of the field, all heavy traffic vehicles must
be kept off the absorption field, with the exception of mowing machines.
• Buildings, corrals for livestock, fences and trenches should not be constructed on top of the
absorption field.
▪ Trees, shrubbery should not be planted within or immediately adjacent to the field's
boundaries.
• Some systems have two absorption fields. These fields are connected by valves so the flow of
the sewage water can be alternated between fields. Talk to a septic maintenance contractor
or the county health department for recommendations on how often to alternate the flow
between the absorption fields.
O We recommend the surface of the field be seeded after installation of the On -site Waste
treatment System. A good native grass cover will prevent erosion. We recommend a seed
mix such as a "Foothills, Pasture, or Prairie" mixes available at local seed stores. These
mixes do not require irrigation and develop a growth 10 to 15 inches high. Automatic
sprinkler systems shall not be installed over the field.
We recommend a minimum maintenance schedule as follows:
1. Sludge and scum accumulation inspected every 1 year.
The rate at which the sludge and scum accumulate in the septic tank varies from household to
household. The only way to know how much solid waste has accumulated is to have it inspected
{If you wish to do this yourself, contact your county health department for information).
2. Sludge and scum accumulation pumped at least every 4 years and preferably every two years.
Sludge and scum must be pumped out of the septic tank before they reach the outlet tee or
baffle. Once sludge and scum reach the outlet tee, instead of staying in the septic tank, they flow
into the absorption field and clog the pores of the soil so it can no longer absorb the liquid.
The owner must realize an OWTS is different from public sewer service. The owner must be
aware of and assume responsibility for maintenance of the system. By following the guidelines
outlined above, your septic system can serve you and your family for many years.
