Onsite Wastewater Treatment System (OWTS) Installation Observations
626 CR 165
Garfield County, Colorado
Permit Number SEPT -04-19-5709
Boone,
ALL SERVICE septic, LLC observed the installation of the onsite wastewater treatment system (OWTS)
on April 25, May 3, May 16, and May 22, 2019 for the subject property. Robin Caudill installed the
system.
The existing sewer line and septic tank serving the residence remained in use. An effluent filter was
added to the outlet tee of the existing septic tank. This filter must be cleaned annually, or as needed.
The existing STA was abandoned in place.
A new 4 -inch diameter SDR -35 sewer line with a minimum 1% fall was installed to a new, 500 -gallon,
single -compartment Roth® poly pump chamber. An Orenco® Biotube Pump Vault and an Orenco®
PF3005 pump was installed in the pump chamber. The floats were set to dose approximately 75 gallons
each pump cycle (5.5 -inch separation), allowing approximately 10 gallons of drain back. The electrician and
installer performed start up on the pumping system. We checked the floats manually and found the
pump and alarm activated normally. The effluent filter in the pump chamber must be cleaned
annually, or as needed.
Effluent is pressure dosed through a 1.5 -inch diameter pump line from the pump chamber to an Orenco®
automatic distributing valve (ADV), model 6402. The ADV was placed a high point in the system and was
placed in an insulated riser with access from grade. We tested the ADV and found it cycled normally.
The STA consists of two chamber beds, each with three rows of 9 `Quick 4' Standard Plus Infiltrator®
chambers for a total of 54 chambers and 648 square feet of infiltrative area. Effluent is pressure dosed
from the ADV through 1.5 -inch diameter level pump lines to level manifolds and 1.5 -inch diameter
laterals, which 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. Orifices were placed 3 -feet on center. Each lateral ends in a 90 degree ell facing up
with a ball valve for flushing. The laterals were flushed at the time of our inspection. Valves were placed
in a valve box, accessible from grade. Inspection ports were placed at each corner of the chamber bed.
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.
