Onsite Wastewater Treatment System (OWTS) Installation Observations
John Neislanik Ranch Rural Development Exemption, Lot 3
Garfield County, Colorado
Permit Number SEPT -08-16-4375
Dave,
Project No. C1240
ALL SERVICE septic, LLC observed the installation of the onsite wastewater treatment system (OWTS)
on February 22, March 15 and 17, September 26, and October 11, 2017 for the subject property. Teagle
Excavating installed the system.
Two sewer lines enter the septic tank. The sewer line from the main house has a double sweep clean
out. The sewer line from the garage/future additional dwelling unit (ADU) has two clean outs and is
properly encased within 10 -feet of the water line crossing. This sewer line wyes into the main house
sewer line prior to entering the septic tank.
The system installation included a 1500 -gallon, two-compartment concrete septic tank an Orenco®
ProPak pumping system and PF3005 pump. The control panel is located within line of sight of the septic
tank, on the east side of the house. Pump start-up was performed by Teagle Excavating. We verified
the pump and alarm were operating properly at the time of our October 11, 2017 inspection.
A 1.5 -inch diameter Schedule 40 pump line was installed from the pump to an Orenco® automatic
distributing valve (ADV), model 6403. The ADV was placed 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 three trenches of 14 Low Profile `Quick 4'
Infiltrator® chambers, for a total of 42 chambers and 504 square feet of infiltrative area. There was at
least 6 -feet of undisturbed soil between each trench. Effluent is pressure dosed to 1.5 -inch diameter
laterals, which is hung with zip ties from the underside of the chambers. Laterals have 5/32 -inch
diameter orifice holes facing up, with the exception of the first and last holes facing down for drainage.
The holes are placed 3 -feet on center. Each lateral ends in a 90 degree ell facing up with a ball valve for
flushing. Valves are placed in a valve box, accessible from grade for access. Inspection ports were
placed at the beginning and end of each trench.
The infiltrative area was placed no more than 1 -foot below native grade to achieve the minimum
required 4 -feet of separation between the infiltrative area and Soil Type 0 (the rocky soil horizon). We
verified the setback from the cistern to soil treatment area (STA) is 103 -feet.
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:
• 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

before discarding in the trash.
Don't:
• Flush non -degradable products or

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.
