County, Colorado
Dear Corey:
A representative of Kumar & Associates observed the installation of the Onsite Wastewater
Treatment System (OV/TS) for the residence at the subject site as required by the Garfield
County Environmental Health Departrnent. Our observations and recommendations are
presented in this report. The services are supplemental to Kumar & Associates agreemenl for
professíonal services to you dated April 16,2019.
'We previously designed the OWTS for the residence as submitted in ourreport dated Jtrne 20,
z}lg,ProjectNo. 19-7-238.02. The system was designed for four bedrooms. The OWTS was
inst¿lled by you.
V/e performed our as-built evaluations on December 23,2021and September 8,2023. The
OWTS components observed included: sewer line, cleanouto septic tank, effluent line, effluent
pump and soil treatment area (STA), and the locations of these components. The installation and
locations of the system components were verified as shown on Figure 1. Pictures of the OWTS
components made during the site visit are included with this report. The distance locations to the
septíc tank shown on Figure 1 were made by taping.
The proposed Valley Precast 1,500-gallon septic tank was changed to a'Westem Gravel 1,500-
gallon septic tank. The proposed Orenco effluent pump was changed to a Munro effluent pump.
The changes are acceptable to us.
On September 8, 2023, after power had been supplied to the pump, a pump performance test was
performed with adequate pump pressure observed.
It is our opinion that the OWTS was installed in general conformance with the above referenced
design.
The observations and recommendations presented above are based on our site observations and
our experience in the area. We make no warranty either express or implied. Alterations to the
system or ímproper backfill and site grading could affectthe operation and effectiveness of the
OV/TS.
