Onsite Wastewater Treatment System Design Installation Observations
414 Pinion Drive
Garfield County, Colorado
OWTS Permit SEPT-9267
Roddy,
CBO Inc. observed the installation of the onsite wastewater treatment system (OWTS) on June 2, 2025
for the subject property. Alpine Excavation and Land Clearing installed the system.
The OWTS design is based on 5-bedrooms. An average daily wastewater flow of 600 GPD was used.
A new 4-inch SDR-35 sewer line tied into the existing sewer line with a wye fitting.
The system installation includee a 1500-gallon, two-compartment Infiltrator® poly septic tank with an
Orenco® Biotube effluent filter on the outlet tee. This filter must be cleaned annually, or as needed.
Risers bring the manhole lids to grade for access.
Effluent gravity flows to a distribution box, and then to two gravelless chamber beds. The distribution box
is accessible from grade and with flow equalizers for equal distribution to each bed.
Level manifolds were installed to connect each row of the chamber beds. The chamber beds consist of 3
rows of 12 ‘Quick 4’ Infiltrator® chambers for a total of 72 chambers and 864 square feet of infiltrative
area. Inspection ports were installed at each corner of the beds.
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 on the expertise of the installer, soil
type, and weather conditions.
Please call with questions.
Sincerely,
CBO Inc.
