GARF)EL.D COI,IIJIY P. O. Box 1438 Basalt, CO 81621 - Subject: Soils Evaluation, Percolation Tests and Design Recommendations for Individual Sewage System Design for a Parcel of Land in Section 8, Township 7 South, Range 87 West of the 6th P.M., numbered as 8076 County Road 113 (Upper Cattle Creek Rd.) Carbondale, CO Dear Don, As requested, Nelson Environmental and Wastewater Solutions, Ltd., performed a soils study and percolation tests to recommend a design for a septic system for the proposed residence being moved from another part of the property. We conducted this study according to Section VII. of the Colorado Department of Health - Guidelines for Individual Sewage Systems (1988). We have based our recommendations on the subsurface conditions encountered. Proposed Construction: This planned residence is an existing three bedroom, two bathroom, two -story house of approximately 1300 square feet, being moved from another location on the property. Site Conditions: The site is a part of a large parcel in Garfield County that constitutes a horse ranching operation. The property is crossed by Cattle Creek and a portion of it consists of the wetlands adjacent to the stream bed. The construction is occurring on a South - facing hillside between the road and the stream. There is a number of barns and corrals adjacent to the building area. The property served by a well. The ground surface, which appears natural in the proposed area of the absorption field, slopes to the South or Southwest at a 12% grade. There are no irrigation ditches in the area of the proposed absorption system. Subsurface Conditions: A soil profile, within 25 feet of the proposed absorption area, was excavated in P.O. Box 6961 Snowmass Village, CO. 81615 Office (303) 923.3289 Home (303) 923.2766 Jimmy Williams Property Septic System Site Evaluation and Design Recommendations April 26, 1994 Page 2 conjunction with the foundation construction. This excavation revealed that no groundwater or bedrock was present within seven and one half feet of the surface of the ground. The subsoil consisted of a loam and clay loam with small cobbles, three to ten inches in diameter, from a depth of 60 inches to the bottom of the profile excavation at 7 1/2 feet. The soil exhibited a slight tendency to swell when wet and compacted under the pressure of the excavating equipment. The subsurface soil conditions were evaluated with the standard percolation test procedures at the approximate location shown on Figure 1. The test holes were initially excavated by backhoe, and this company completed the percolation test hole preparation by digging a small twelve -inch diameter hole in the bottom of each excavation with hand tools. Percolation Testing: Percolation testing was performed in the proposed absorption trench area uphill to the North and west of the residence foundation. This testing was performed in the three shallow holes excavated to a depth of approximately forty -eight inches. Gravel was placed into the bottom of each small percolation test hole to protect the bottom of the hoie from scouring when water was added. The percolation holes were pre - soaked before our testing by adding water the evening before and again approximately four hours before beginning the percolation test. The results of the percolation testing are presented in Table I. These results indicate the loam soils have an average percolation rate of 21 minutes per inch, a satisfactory percolation rate under County criteria. Minimum County Requirements: The percolation rates in the loam and clay loam subsoils were measured at an average of 21 minutes per inch. The minimum Garfield County requirements for this installation are based on a system flow of 450 gallons per day. This flow would require a septic tank of 1000 gallons minimum volume, and a minimum of 620 square feet of standard absorption trench. Under some jurisdictions, an additional 60% of the absorption area required must be provided if there is a washing machine or garbage disposal in the residence, bringing the total area requirement to 992 square feet. Although this may not be required, we believe it is prudent to size the absorption with a washing machine and disposal in mind. Jimmy Williams Property Septic System Site Evaluation and Design Recommendations April 26, 1994 Page 3 A standard absorption trench is defined as follows: A standard absorption trench is an excavation less than three -feet (3') wide and containing a single 4 -inch (4 ") perforated distribution pipe in the center. A minimum of six - inches (6 ") of 112 inch to 2 1/2 inch diameter gravel is placed under the distribution pipe. A sufficient amount of additional gravel is placed around and over the distribution pipe and to bed and cover the pipe with a minimum of two inches (2 ") of gravel. A minimum of two trenches is required for any such installation. Recommended On -site Wastewater Disposal Design: We recommend that the sewage system consist of a 1250- gallon concrete septic tank, a pumping chamber and effluent pump and several laterals of absorption trench. The site is quite a distance from the main roads. As a result. we believe that the access to this relatively remote area makes the use of gravel somewhat less attractive, and would suggest that you plan a method of construction that uses one of the graveless systems. The use of "Infiltrator"TM leaching chambers, or the like, also permits a 50% reduction in absorption area under State Guidelines. This reduction is based on manufacturer's claims and on an approval of such a reduction by the Colorado Department of Health, Water Quality Control Division. This type of construction would require 167 lineal feet of shallow trench excavation, three feet wide. Therefore, the suggested design incorporates the use of the alternative listed above. We recommend that the septic system consist of the septic tank and pumping chamber, receiving gravity flow of the wastewater from the residence, and two trenches, located uphill close to the County Road, each 84 feet long. These trenches would then receive a dose of effluent approximately four times a day from the discharge of the pump. It is advisable to excavate these trenches as shallow as possible, to a depth of no more than four feet, and to place each of the trenches on contour. The minimum required separation between trenches is six feet, although excavators often find that a ten foot separation is easier to install. Because of the space limitations and the requirement to provide a 50 foot horizontal separation to the creek, it is be necessary to install the 1000 gallon dosing chamber and pump to the "Infiltrator" trenches. The distribution pipe should be a small diameter line suspended in the crown through the sections of leaching chamber, as shown on the Jimmy Williams Property Septic System Site Evaluation and Design Recommendations April 26, 1994 Page 4 manufacturer's specifications. The two -inch manifold from the pump could then be directly connected to the chambers. No distribution box is required. Limitations: This report has been prepared according to generally accepted practices in this area for use for sewage disposal design purposes. The conclusions and recommendations submitted in this report are based upon data obtained from our site visits at the location indicated. There is some possibility that the nature and extent of variations in the subsurface soils across the site may not have been evident at the time of this investigation, and may need additional evaluation if further excavation reveals conditions different from those described. This office should be advised of any unusual situations as soon as possible so we may reevaluate our recommendations. If you have questions or if we may be of further assistance, please call the office. Sincerely, /Id/ Robert F.
