Onsite Wastewater Treatment System (OWTS) Installation Observations
360 Cerise Ranch Road
Garfield County, Colorado
OWTS Permit SEPT-8022
Glynna,
CBO Inc. observed the installation of the onsite wastewater treatment system (OWTS) on November 13,
2023 for the subject property. King Construction installed the system.
The OWTS design is based on 5-bedrooms. An average daily wastewater flow of 600 GPD was used.
The 4-inch diameter SDR-35 sewer line exiting the residence had a double-sweep clean out and a
minimum 2% grade to the septic tank.
The system installation included a 1500-gallon, two-compartment Infiltrator® poly 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 five 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.
The first trench consists of 13 ‘Quick 4’ Standard Plus Infiltrator® chambers, the middle trench consists of
15 chambers, and the remaining trenches consist of 14 for a total of 70 chambers and 840 square feet of
infiltrative area. There must be 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.
