Dean Residence Septic Field Expansion As -Built Conformance
Permit No. SEPT -8-09-1208
Dear Jim:
SGM
www.sgm-inc.com
Vail Engineering prepared a design for construction of an Individual Sewage Disposal System
(ISDS) to serve the Gambrel -Loft Barn addition located at 1136 County Road #129, Garfield
County, Glenwood Springs, CO 81601, for Whitney and Megan Dean. The ISDS was completed
by Starkworks Inc. in the month of August of 2009 under Permit No. SEPT -8-09-1208. The ISDS
was designed and constructed to accommodate the existing home, with the addition of the
Gambrel -Loft Barn.
SGM reviewed the as -built documentation, photos, and field notes, on February 21, 2017. The
proposed Loft Barn was connected to the existing ISDS system by installing a new 1,000 gallon
septic tank with effluent filter and connected to the existing drain field by installing a 4" PVC
service line at a 2% slope approximately 100 feet long with cleanouts before and after the septic
tank. Additionally, the drain field was expanded by 336 square feet adsorption bed for the
additional loading.
The original design for the existing septic field that was permitted on 5/23/89, called for the same
1,000 gallon Septic Tank, and 260 sq ft. of absorption area per bedroom. This percolation rate was
based upon site data of 1 inch of percolation in 13 minutes. The percolation test is attached. The
more recent ADU addition that was permitted on 9/8/09 is one bedroom and placed an additional
absorption area of 336 square feet. on line, in directly adjacent soils of similar properties.
