Onsite Wastewater Treatment System (OWTS) Installation Observations
Lot 13, Rock Creek Subdivision
Garfield County, Colorado
Permit Number SEPT-04-18-5217
Tim,
ALL SERVICE septic, LLC observed the installation of the onsite wastewater treatment system (OWTS)
on June 16, 2019 for the subject property. Dirt Devil Excavation installed the system.
The installation included a new 1250-gallon, two-compartment septic tank with an Orenco® ProPak and
PF3005 pump in the second compartment. The effluent filter in this compartment must be cleaned
annually, or as needed. Floats were set to dose approximately 80 gallons per pump cycle, allowing 9
gallons of drain back after each pump cycle. The control panel for the pumping system is located in the
garage. Dirt Devil Excavation performed start-up of the pumping system.
Effluent is pressure dosed through a 1.5-inch diameter pump line from the septic tank to 1.5-inch
diameter level manifold. The pump line had a minimum 1% grade for proper drain back into the septic
tank.
The STA consists of a chamber bed with three rows of 9 ‘ARC’ ADS Low Profile chambers for a total of
27 chambers and 405 square feet of infiltrative area. Burial depth of the chambers was shallow, with a
maximum depth of 2-feet below native grade.
Effluent is pressure dosed to 1.5-inch diameter laterals, which were hung with zip ties from the underside
of the chambers. Laterals will have 5/32-inch diameter orifices facing up, with the exception of the first
and last holes facing down for drainage. The holes were placed 3-feet on center. Each lateral ends in a
90 degree ell facing up with a ball valve for flushing. Valves may be placed in a valve box, accessible
from grade. Inspection ports must be placed in each corner of the bed. Ports may be cut to grade and
covered with a valve box for access.
Irrigation should be discontinued in the area of the STA, with the exception of establishing native grasses
over the 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 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,
