Onsite Wastewater Treatment System (OWTS) Installation Observations
Masonry Barn Renovation
531 CR 153
Garfield County, Colorado
Permit Number SEPT-03-17-4598
Mike,
ALL SERVICE septic, LLC observed the installation of the onsite wastewater treatment system (OW TS)
on May 23, 2017 for the subject property. Patch/Vinger installed the system.
The system installation included a new 1000-gallon, two-compartment Forterra concrete septic tank with
an effluent filter on the outlet tee. This filter must be cleaned annually, or as needed.
A distribution box, accessible from grade, was installed. Flow equalizers were installed to assure equal
distribution to each trench. The new soil treatment area (STA) consists of three rows of 6 ‘ARC’ ADS
chambers for a total of 270 square feet of infiltrative area. Trenches were separated by at least 6-feet of
undisturbed soil. Inspection ports were installed at both the beginning and end of each trench.
Inspection ports may be cut to grade and covered with a sprinkler box for access.
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 Reviewed By:
