RE: Individual Sewage Disposal System Application
Public Service Company of Colorado (PSC) Shoshone Hydro Facility
Dear Mr. Hougland:
Attached please find a completed Individual Sewage Disposal System
Application for the PSC Shoshone Hydro Facility located in Glenwood Canyon. PSC
proposes the installation of a drywell (seepage pit) for disposition of effluent from an
existing package chemical domestic sewage treatment system. The facility generates
approximately 200 gallons per day (gpd) of effluent from this system; accordingly,
the drywell has been designed to handle 368 gpd of treated effluent.
PSC appreciates your prompt review and approval of this application, so that
installation of the drywell can be expeditiously initiated. The facility is currently
collecting the treated effluent in a 500 gallon polyethylene tank for disposal by a
sewage disposal company. Upon approval of this permit application, please FAX a
copy of the permit to me at (303) 294 -2829 or contact Randy Roweton at (303) 244-
2660 in Grand Junction.
If you have any questions regarding this application, please contact me at (303)
294 -2814 or Randy Roweton. Thank you for your cooperation in this matter.

PER COI .ATION TESTS
The successful operation of your septic system depends on the rate the soil in which your leach field will be
installed will accept water. This is critical The rate of absorption is called the percolation rate and it
determines the size of the leach field needed for a particular flow of sewage and in some cases even determines
the feasibility of the installation of a septic tank and leach field system. AN EIGHT (8) FOOT PROFIT .F.

A post hole digger, auger, or back hoe can be used to dig the percolation test holes. If a back hoe is used, dig
the back hoe hole 3 feet deep and put a test hole 1 foot deep and 8 to 12 inches in diameter in the bottom.
Installation of absorption areas (i.e. drywells) deeper than three feet requires the permission of the
Environmental Health Department.
Saturation with water will affect the percolation rate, and since the system will be expected to operate when
the soil is saturated with water, THE HOT .FS MI JST BE FIT T.F.D WITH WATER AT T.EAST 8 HOURS

RECOMMENDED MINTMTJM RFQIJIREMENTS FOR
INDIVIDIIAI. SEWAGE DTSPOSAT. SYSTEMS
Before construction is started, the Inspector must be contracted for approval and detailed information
concerning the proposed disposal system. Higher standards than those which follow may he required in
individual cases to assure attainment of the objectives Those objectives are to locate, construct, and maintain
individual sewage disposal systems in such a manner that existing or comtemplated water suplies will not
become cintaminated and so that sewage will not overflow the ground surface and result in a nuisance or
health hazard.

*Percolation rates faster than 5 minutes per inch or slower than 60 minutes per inch require engineered
systems and /or Board of Health approval.
(a) It is desirable to provide sufficient land area for entire new absorption system if needed in future.
(b) In every case, sufficient land area should be provided for the number of bedrooms (minimum of 2) that
can reasonably anticipated, including the unfinished space available for conversion as additional
bedrooms.
(c) Absorption area is figured as trench- bottom area and includes a statistical allowance for vertical side
wall area.

(d) Absorption area for seepage pits is figured as effective side wall area beneath the inlet.
(e) Unsuitable for seepage pits if over thirty.
(0 Unsuitable for absorption systems if over sixty.
Dwelling on less than two acres, areas of high water tables, or areas with a percolation test rate faster than
1" in 5 minutes must have alternative sewage facilities, i.e., central collection, holding tanks, individual
treatment, etc.
EXCEPTION: Absorption areas may be allowed with percolation rates faster than one (1) inch in 5 minutes
provided the soil is a sandy texture and no water table problems are encountered.
1. Maximum length of drainage line: 100 linear feet
2. Minimum width of drainage trench: 18 inches
3. Minimum spacing between trenches or pipes: 6 feet
4. Maximum grade of drainage lines: As level as possible
5. Minimum depth rock under drain PVC: 6" under PVC, 2" over PVC
6. Minimum depth of cover over distribution lines: 12 inches
7. Maximum depth of cover over distribution lines: Variable
8. Minimum grade of house sewer: 1/8 to 1/4" per linear ft.
9. Minimum distance of sewage disposal system
from dwelling: 10 feet
10. Minimum distance of leaching area to a well: 100 feet
11. Minimum distance of septic tank to a well: 50 feet
12. Minimum distance of leaching area to a stream
of water course: 50 feet
13. Minimum distance from septic tank and disposal
field to property lines: 25 feet for drywell;
10 feet for leach field
14. Minimum sewer pipe and distribution pipe: 4 inch diameter
Septic construction should be of concrete, concrete block or of a material that will resist deterioration and
which can be made reasonably watertight.
Acceptable drain field pipe materials include plastic, terra cotta, concrete. If the house sewerline is longer
than 10 feet between house and septic tank, a clean -out Y should be installed as near as practicable to the
house.
Septic tanks should be inspected once a year and cleaned when necessary. Cleaning is recommended when
space between the scum accumulation and sludge residue on the tank bottom is less than 18 inches.
The Department recommends pumping a septic tank once every 4 years when a yearly inspection by the owner
is not practical.
