Dear Andy,
Enclosed is the Onsite Wastewater Treatment System (OWTS) permit application for
the residence at 0283 Sunny Acres Rd., Glenwood Springs, CO 81601. Attached is a
plan view of the residence which shows the current septic system and also the
proposed leach field repair locations.
Repairs are required on the 25 year old septic/ leach system due to sewer backup
issues. In order to pinpoint the problem, the 4" PVC sewer pipe between the foundation
wall and the septic tank, as well as the pipe between the septic tank and the leach field
(infiltrators) was pressure jetted and inspected by camera.
The rubber fernco coupling, which connects the sewer pipe at the foundation wall, had
slipped off of the pipe. Sewer water could not flow freely to the septic tank. Necessary
repairs have already been made to correct the problem and restore drainage to the
septic tank.
During the inspection process, root growth on the inside of some infiltrators was
detected. To prevent future leaching issues it is necessary to make repairs and
replacements to the system. The plan is to remove and replace some existing root filled
infiltrators in accessible locations and place additional infiltrators at a new location.
The original design required 249 Sq.Ft. of leaching area. It proved to be totally adequate
over 25 years of service. The repairs that are proposed will also provide 249 Sq.Ft. of
leach area.
The Infiltrations Systems, "Quick 4 Plus Standard Chamber", will be utilized. Should it
be determined, during the field work, that it is necessary to place infiltrators under the
main portion of the driveway, Infiltrations Systems "High Capacity Infiltration Chamber
H-20" infiltrators will be used.
Miles Rippy Excavating, Inc. is being contracted to perform the work. We hope to have
the work permit in hand so that he may proceed as soon as his work schedule allows. I
am a Colorado Licensed Professional Engineer,(see attached) as well as the owner of
the property. I will be on site during the course of the project. If there are any questions,
please contact me, Tom Metheny, or Dave Gray who currently occupies the residence.
Sincerely,
-772,
