Onsite Wastewater Treatment System (OWTS) Installation Observations
532 Westbank Road
Garfield County, Colorado
Septic Permit # SEPT-12-19-6080
Bob,
Project No. C1461
CBO Inc. observed the installation of the onsite wastewater treatment system (OWTS) on January 16 and
March 26, 2020 for the subject property. Miles Rippy Construction installed the system.
The existing septic tank was pumped and crushed, and the remaining void filled with onsite material. The
existing soil treatment area was abandoned in place.
The new OWTS design is based on 4-bedrooms. An average daily wastewater flow of 525 GPD was
used.
The cast iron sewer line existing the residence was replaced with 4-inch diameter SDR-35 sewer line and
a double -sweep clean out was added to the sewer line between the residence and the new septic tank.
A new 1500-gallon, two -compartment Infiltrator® poly septic tank was installed with Orenco® Biotube
effluent filter on the outlet tee followed by a 500 gallon, single -compartment Infiltrator® poly septic tank
with an Orenco® ProPak pumping system and PF3005 pump. The effluent filters need to be cleaned
annually, or as needed. The floats were set to dose approximately 60 gallons each pump cycle, allowing
1 gallon for drain back. The control panel is located within line of sight of the septic tank. Valley
Precast out of Buena Vista performed start up on the pumping system.
A 1.5-inch diameter Schedule 40 pump line was installed from the pump to an Orenco® automatic
distributing valve (ADV), model 6404. This pump line has a minimum 1 % grade for proper drain back into
the tank after each pump cycle. The ADV was placed at a high point in the system (near the pump tank)
and was placed in an insulated riser with access from grade.
Effluent is pressure dosed through FOUR 1.5-inch diameter pipes to two beds, each with 4 rows of 11
`Quick 4' Low Profile Infiltrator® chambers, for a total of 88 chambers and 1056 square feet of infiltrative
area. It should be noted that each bed is divided into two sections, so two rows will be connected with a
single manifold. There is at least 6-feet of undisturbed soil between each bed. The infiltrative area was
not placed more than 2-feet below grade in order to maintain the required 4-feet of suitable soil below
the infiltrative surface as Soil Type R-0 with a high percentage of gravels are present at 6-feet below grade.
Laterals were hung with zip ties from the underside of the chambers. Laterals have 5/32-inch diameter
orifices facing up, with the exception of the first and last holes facing down for drainage. The orifices were
drilled 3-feet on center. Each lateral ends in a 90-degree ell facing up with a ball valve for flushing. Valves
were placed in a valve box, accessible from grade, for access. Inspection ports were placed in each corner
of each bed. Ports were cut to grade and covered with a valve box for access.
The OWTS was generally installed according to specifications. This observation is not a guarantee of
workmanship and/or parts and materials. CBO Inc. should be notified if changes are made to the OWTS
in the future. Any additional OWTS construction must be according to the county regulations.
LIMITS:
Observations are limited to components that are visible at the time of the inspection. The installer must
have documented and demonstrated knowledge of the requirements and regulations of the county in which
they are working. The quality of the installation is dependent of the expertise of the installer, soil type, and
weather conditions.
Please call with questions.
Sincerely,
ALL SERVICE septic, LLC

Do Your Part, Be SepticSmart:
The Do's and Don'ts of Your Septic System
Learn these simple steps to protect your home, health, environment and property value:
septicsmart
U.S. Environmental Protection Agency
Do:
• Have your system inspected (in general) every three years by a licensed contractor
and have the tank pumped, when necessary, generally every three to five years.
Don't:
• Pour cooking grease or oil down the
sink or toilet.
• Rinse coffee grounds into the sink.
• Pour household chemicals down the
sink or flush them.
Do:
• Eliminate or limit the use of a garbage
disposal.
• Properly dispose of coffee grounds a
food.
• Put grease in a container to harden
before discarding in the trash.
Don't:
• Flush non -degradable products or
chemicals, such as feminine hygiene
products, condoms, dental floss,
diapers, cigarette butts, cat litter, paper
towels, pharmaceuticals.
Do:
• Dispose of these items in the trash can!
Don't:
• Park or drive on your drainfield. The
weight can damage the drain lines.
• Plant trees or shrubs too close to your
drainfield, roots can grow into your
system and clog it.
Do:
• Consult a septic service professional to
advise you of the proper distance for
planting trees and shrubs, depending on
your septic tank location.
Don't
• Concentrate your water use by using
your dishwasher, shower, washing
machine, and toilet at the same time.
All that extra water can really strain
your septic system.
Do:
• Stagger the use of water -generating
appliances. This can be helpful
especially if your system has not been
pumped in a long time.
• Become more water efficient by fixing
plumbing leaks and consider installing
bathroom and kitchen faucet aerators
and water -efficient products.
