Onsite Wastewater Treatment System (OWTS) Installation Observations
187 CR 259
Garfield County, Colorado
Permit Number SEPT -08-19-5924
Emily,
ALL SERVICE septic, LLC observed the installation of the onsite wastewater treatment system (OWTS)
on September 8, 2019 for the subject property. Avalanche Excavation installed the system.
The existing septic tank was pumped and crushed, and the void filled with onsite soils. The existing STA
was abandoned in place.
The new OWTS design was based on 4 -bedrooms. An average daily wastewater flow of 525 GPD was
used.
There are two sewer lines exiting the residence. They were replaced with 4 -inch diameter Schedule 40
and include a clean out and minimum 2% grade to the septic tank.
The installation included a 1500 -gallon, two-compartment poly Roth® septic tank followed by a 500 -
gallon poly Roth® pump chamber with an Orenco® ProPak pumping system and PF3005 pump. The
floats were set to dose approximately 50 gallons each pump cycle. There is an effluent filter in the
pump chamber that must be cleaned annually, or as needed.
Risers were installed on the septic tank to bring access to grade. 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 6606. The ADV was placed at a high point in the system in an insulated riser
with access from grade.
Effluent is pressure dosed through 1.5 -inch diameter pipes to six trenches, each with 14 `Quick 4'
Infiltrator® chambers, for a total of 84 chambers and 1008 square feet of infiltrative area. There was at
least 4 -feet of undisturbed soil between each trench. Laterals, which were 1.5 -inch diameter, were hung
with zip ties from the underside of the chambers. Laterals had 5/32 -inch diameter orifices facing up, with
the exception of the first and last holes facing down for drainage. The orifices were placed 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 at the beginning and end
of each trench. Ports may be 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. ALL SERVICE septic, LLC 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:

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.
