Onsite Wastewater Treatment System (OWTS) Installation Observations
272 Scutter Ridge Road
Garfield County, Colorado
Permit Number SEPT-12-21-7281
James and Amy,
CBO Inc. observed the installation of the onsite wastewater treatment system (OWTS) on July 12, 2022
for the subject property. You, the property owner, installed the system.
The OWTS design is based on 4-bedrooms. An average daily wastewater flow of 525 GPD was used.
The 4-inch diameter SCH-40 sewer line exiting the residence has a double-sweep clean out and a
minimum 2% grade to the septic tank.
The system installation included a minimum 1500-gallon, two-compartment poly Infiltrator® septic tank
with an 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 six gravelless chamber trenches. The distribution
box was accessible from grade with flow equalizers installed on each outlet pipe in the distribution box to
assure equal flow to each trench.
Each trench consists of 15 ‘Quick 4’ Standard Plus Infiltrator® chambers for a total of 90 chambers and
1080 square feet of infiltrative area. There was at least 4-feet of undisturbed soil between each trench.
Inspection ports were installed at the beginning and end of each trench. Ports may be cut to grade and
placed in sprinkler boxes 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 on the expertise of the installer, soil
type, and weather conditions.
Please call with questions.
Sincerely,
CBO Inc.

Permit Conditions:
This OWTS Permit is approved on the condition of compliance with the report and design as
submitted by CBO, Inc. dated March 30, 2023. Changes to the design and permit must be approved
by Garfield County Public Health and the designer prior to construction.
The new OWTS will serve a new 4-bedroom residence. The system will consist of a new, two-
compartment minimum 1,250-gallon septic tank set level with access to grade and an effluent filter
in the outlet tee of the tank. Effluent will gravity flow to a distribution box set level with access to
grade that will distribute effluent to 1,080 ft2 of STA. The new STA will consist of six gravelless
chamber trenches. All six trenches will consist of 15 Quick4 chambers (90 Quick4 chambers total).
Inspection ports are to be installed at the beginning and terminal ends of each trench. Maintain all
setbacks and elevations as designed.
Contact the designer and Garfield County Public Health at least 48 hours prior to requesting final
inspection of the installed system prior to backfill.
