OWTS Permit #: SEPT-9285
November 17, 2025
On September 12, 2025, we visited the site of the residence under construction at 9071 County Road 313
near New Castle in Garfield County, Colorado to observe the OWTS installation pursuant to OWTS
Permit # SEPT-9285. The system was designed by CBO, Inc. and installed by Avalanche Excavation. We
received an as-built drawing of the constructed system and a letter certifying that the system was
constructed in compliance with the permitted design from the OWTS designer dated November 3, 2025.
During our inspection, we observed the new sewer line and cleanout adjacent to the residence, the new
concrete 1,500-gallon two-compartment septic tank with a high-head Orenco pump package in the second
compartment of the tank, the new pump line, the new automatic distributing valve, and the Soil Treatment
Area (STA). The septic tank and automatic distributing valve were installed level with access brought to
grade. The STA consisted of 10 feet by 52.5 feet by 1-foot-deep pressure-dosed unlined sand filter
constructed with secondary sand media (525 ft2 total STA). The STA consisted of 3 distribution laterals
constructed of 1.5-inch diameter Schedule 40 PVC with 5/32-inch diameter orifices every 3-feet on
center, facing down, placed in GeoMat distribution media. The distribution laterals ended in a 90-degree
sweeping bend facing up, fitted with a ball valve to allow flushing of the laterals. Additionally, inspection
ports were present at each corner of the bed.
As required by Garfield County OWTS Regulation Section 43.4.F.3, based on our final inspection
observations, this OWTS was installed according to the permit requirements and regulations.
Thank you,
