Onsite Wastewater Treatment System (OWTS) Installation Observations
Lot 1, Ranch at Coulter Creek
Garfield County, Colorado
Permit Number SEPT-6149
Robbie,
CBO Inc. observed the installation of the onsite wastewater treatment system (OWTS) on April 13, 2020
for the subject property. Jimmy Condon installed the system.
The OWTS design is based on 4-bedrooms. An average daily wastewater flow of 525 GPD was
used.
The system installation included a 1250-gallon, two-compartment concrete 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.
Each trench consisted of 15 ‘Quick 4’ Low Profile Infiltrator® chambers for a total of 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 of the expertise of the installer, soil
type, and weather conditions.
Please call with questions.
Sincerely,
CBO Inc.
