Onsite Wastewater Treatment System (OWTS) Installation Observations
Lot 12, Callicotte Ranch
Garfield County, Colorado
Garfield County Permit No. SEPT-9-13-2970
Brad,
ALL SERVICE septic, LLC observed the installation of the onsite wastewater treatment system
(OWTS) on July 7 and November 12, 2014 for the subject property.
The installation included a new 1250-gallon, two-compartment Roth® poly septic tank with an
effluent filter on the outlet tee. This filter must be cleaned annually, or as needed.
Effluent gravity flows to a distribution box, accessible from grade, and then to four gravelless
chamber trenches. Each trench consists of 18 ‘Quick 4’ Infiltrator® chambers for a total of 72
chambers and 711 square feet of infiltrative area.
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 OW TS 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:
