OWTS Construction Approval Letter BLRE-03-16-4091
The proposed OWTS field design for Lot 5, Roaring Fork Preserve in Garfield County, Colorado has been
installed per the approved and pennitted plans (Pennit Number BLRE 03-16-4091 ). The installation
contractor was Hughes Excavating, Hughes Excavating Company P.O. Box 606, Carbondale, CO 81623
The chambers were trenched down to the tested soil elevation and installed on native material that was
reviewed prior to the chambers being installed. The soils were consistent through the chamber trenches as
per what was described within the geotechnical report prepared by HP Geotech, Inc. Job No. 100627, dated
11-30-2000. The fields are located in their general area of design and have proper separation from trench to
trench. The fields are equal to the required 41 units shown on the approved plans. The chamber 2" pipes
were run through the upper ports on the end caps and through the chambers with the piping being attached to
the top of the chambers per dosing requirements. The ports that were installed were brought to above grade
as required per photos.
The septic tank meets sizing requirements and pump requirements per the design and has an inlet drop per
design. The internal dosing pump was reviewed by Hughes Excavating Company, the installer of the pump
and tank system, and has been approved as functioning per design (letter is attached). The tank lids have
been raised to the proper elevation above grade and backfilling of the trench and septic tank dig have been
completed.
Attached are photos of the installation.
Please let me know if you have questions pertaining to this acceptance letter submittal.
Thank you,
