Subject: OWS Design, Proposed See Residence
Lot 9, Cedar Hills Ranch Subdivision
0774 Cedar Hills Road
Garfield County, Colorado
Job No. 12795
Dear Mr. Davis,
M requested, we have reviewed subsurface conditions prepared by HP Geotech for the subject site and
prepared an onsite wastewater system (OWS) design fbr the proposed residence. The subsurface
investigation was performed per the HP report dated on May 17, 2000.
SITE CONDITIONS
The property is located in a residential. area in Garfield County where OWS are required. The proposed
drain field area is on a south trending ridge with a 5% slope and has a thick cover of native grasses with
surrounding scrub oak. The proposed residence will be served water by an onsite well located 100+ feet
from the proposed drain field.
PROPOSED CONSTRUCTION
A four - bedroom residence is proposed at the location presented on Figure 1. We have sized the OWS based
on 4 bedrooms and 600 Gallons Per Day (GPD) using Garfield Health Department loading of 75 gallons
per day per person. The peak sewage load is 900 GPD. This loading includes garbage grinders and washing
machines. The drain field is to be a minimum of 100 feet to all existing and proposed weds.
SUBSURFACE CONDITIONS
HP Geotech performed a subsurface investigation by digging 3 percolation holes, 45 to 48 inches deep, and
one 8 foot profile pit at the locations described in the HP Geotech report, dated May 17, 2000, and
displayed as Appendix A. Subsurface conditions in the profile pit consisted of 0.5 foot of topsoil, underlain
by calcareous sandy silt tot feet, underlain by blocky sandy clay tithe maximum depth explored of 8 feet.
Percolation tests indicate percolation rates of 120 to 240+ minutes per inch (MW). Percolation data is
presented in Appendix A. For very slow percolation rates, such ati these, we use a percolation rate of 180
MPI which is converted to an application rate of 0.15 gals/SF /day.
The proposed field is to the of the HP percolation tests. The soils and percolation tests indicate a worst case
conditions and we have move the field to the south of the HP tests to locate the field in a more buildable
location. We believe subsurface conditions can be no worse that those at the tested location.
