Onsite Wastewater Treatment System (OWTS) lnspection
1655 CR 109
Garfield County, Colorado
Brent,
As requested, CBO lnc. performed an Onsite Wastewater Treatment System (OWTS) inspection at 1655
CR 109, Glenwood Springs, Colorado on July 21,2021. The legaldescription of the 4.45-acre property
is as follows:
Subdivision: Section: 12 Township: 7 Range: 89 Subdivision: LOUGH SUBDIVISION Lot: A-1 RESUB
oF PARCEL A OF COLOHAN EX. (4.453 ACt)
Parcel lÐ: 2395-123-02-002
The permit (enclosed) was provided by Garfield County Community Development Department. The
subject OWTS consists of one 2000-gallon, two-compartment concrete septic tank followed by a soil
treaiment area (STA) comprised of tl'rree gravelless chamber trenches, each with 9 'Standard' lnfiltrator@
chambers for a total of 27 chambers and 506.25 square feet of infiltrative area. lndividual Sewage
Disposal System (ISDS) Permit 2937 documents the system. The permit received final approval on June
5, 1ggg. T-ne sysiem was sized to accommodate 4 bedrooms. You have also stated that the original
1500-gallon seþtic tank was replaced with a 200O-gallon, two-compartment concrete septic tank in the
location noted on the site plan (enclosed).
The existing 3-bedroom residence on the property is served by a shared water system and there is no
on-site wel[ The proposed 1-bedroom accessory dwelling unit (ADU) will be located down-gradient from
the existing septic tank. An ejector pump is proposed to lift wastewater to the existing OWTS.
The septic tank is located in between a circular drive, to the south of the existing office and east of the
existing barn. The septic tank lids were approximately to grade. The lids were showing signs of
deterioration and were replaced. An inlet tee was present, but there was no outlet tee or effluent filter.
We recommend adding an effluent filter on the outlet pipe. A handle extension will be necessary for ease
of inspection and maintenance. lf installed, we recommend cleaning the effluent filter annually, or as
needed. We also recommend the outlet line from the septic tank be jetted because there is no sanitary
tee present.
The soil treatment area (STA) is located to the east of the existing 3-bedroom residence and south of the
driveway. The distribution box is not accessible from grade and therefore could not be inspected. We
recommend locating and bringing access to grade for future inspection and monitoring. No inspection
ports were observed. We walked the approximate STA and found no evidence of surface saturation or
failure at the time of the inspection.
This evaluation is not a guarantee of future system performance'
Recommendations:o lnstall ettluent filter on outlet pipe. (Specifications enclosed). Pump soptic tank.. Jet outlet sewer line from septic tank.. Locate distribution box and bring access to grade for future monitoring and inspection
