Rd. 335 New Castle, Colorado 81647 RE: Individual Sewage Disposal (ISDS) Report Greene Residence, New Castle, Garfield County, CO Dear Thad: Per your request, Schmueser Gordon Meyer has evaluated the design of the proposed septic system to service the residential flows from the proposed Greene Residence located northwest of New Castle in Garfield County, Colorado. Based upon conversations with yourself, we understand that the design of the individual sewage disposal system will be designed for a four bedroom home. We have conducted an on -site soils investigation (ie., perc test), and have attached the results herein. We have identified an average percolation rate for this property to be 14 minutes per inch. The soils investigation did not identify the presence of ground water or bedrock within the upper eight feet of soil at the site of the disposal field. Based upon the percolation test results and the soil observations, it appears that a standard (each field system can be installed on this site. This, of course, assumes that setback requirements can be met in accordance to Colorado State Health Department regulations. Accordingly, we have attached a table from the Colorado Department of Health 1SDS regulations which identify the required setbacks for each component of the septic system installed. The proposal for this site as far as method of disposal considers the use of a standard "infiltrator" system. This system, as proposed, will be installed in a trench -type fashion. Accordingly, we have attached manufacturer's product information regarding the infiltrator and the infiltrator system installation. To briefly describe the septic system as a whole, it is proposed to collect the effluent from the main waste line from the house to a 1250 gallon septic tank. Please note that this 1250 gallon concrete septic tank does have alternative installations available. These alternative installations can be considered, considering the fact that no evidence of high groundwater is present. The alternative installations that can be considered with this type of septic tank is that of a fiberglass septic tank also equal to 1250 gallons. We have not provided information as to a specified manufacturer or product line for fiberglass septic tank. Please note that the septic tank must be located pt least five feet away from the residence. In addition, the effluent line leaving the house and goin to the septic tank must be straight in alignment and straight in grade. If it is deemed necessary that any change in alignment and /or grade in this main line from the house to the septic tank is required, a cleanout will be necessary to accompany the installation. This main line coming from the house to the septic tank must be a minimum specification ASTM 2729 PVC pipe of minimum 4" diameter. The grade of the pipe must he at a minimum of Y4" per foot. If it becomes necessary that the main line must cross a traveled area (i.e. vehicular access), we would then recommend that the pipe specifications increase in strength to no longer utilize an ASTM 2729 designation but rather use a Schedule 40 PVC. To compensate for differential settling between the septic tank and the incoming and outgoing piping, we would recommend that the piping coming into and leaving the septic tank be sleeved in a 6" diameter cast iron pipe or Schedule 40 PVC. Once the effluent line leaves the septic tank, it will need to proceed towards the infiltrator trench system at a 3/4" per foot grade. Again, the minimum diameter of this pipe would need to be that of 4 ". We would recommend that, from this point to the infiltrator system, location of the infiltrator system and piping be coordinated such that no vehicular access is allowed over the piping or the infiltrator system. Additionally, with this recommendation, we would then maintain that the ASTM 2729 PVC piping be utilized. For the disposal system itself, we would recommend that three infiltrator trenches be installed. We have attached our calculations which define the length of infiltrator trench necessary as well as the number of infiltrator units necessary per trench. The closest spacing that the infiltrator units can be installed is 10 feet on center. The infiltrator units must be placed in a flat trench. We have attached a sketch which identifies the typical piping requirements to equally distribute flow to each of the infiltrator trenches. As previously discussed, we have attached the manufacturer's literature regarding the infiltrator system. With that manufacturer's literature is a detailed list of instructions regarding the septic system installation. You will note that the backfill required over an infiltrator trench is that of native backfill. This native backfill is acceptable for fill over the trenches as long as 6" and larger rock is not allowed in the backfill. The minimum requirement of 12" of cover over the infiltrator system is also identified. Please note that the infiltrator must be installed in an excavated trench and not in fill. As mentioned throughout this report, a number of attachments are included with this report. Please find the following list which identifies specifically the attachments in order: 1. Calculation of leach field and septic system sizing. 2. Table of minimum horizontal setbacks. 3. Percolation test results. 5. Schematic plan view of septic system installation. 6. Sketch of the standard infiltrator chamber. SCHMUESER O6RDON MEYER, INC. 7. Infiltrator manufacturer's literature. 8. Septic system installation instructions (from Infiltrator manufacturer literature). Some general notes that must be mentioned regarding any septic system installation are as follows: 1. All materials, installation practices and setback requirements shall comply with Garfield County Individual Sewage Disposal System Regulations. 2. The infiltrator trench shall be constructed so that the bottom level of the trench is + 0.1 inches. Place trench in natural ground, no portion of the trench shall be placed in fill. Once backfilled, provide positive drainage way from the trenches. 3. The area disturbed by construction shall be reseeded by native grasses to prevent erosion. 4. Use risers as needed to bring septic tank access hatches within 6" of finish grade. 5. Locate septic tank such that the access to the tanks can be accommodated for future pumping. 6. The contractor and owner shall take whatever measures are necessary to assure that (a) the septic tank and sewerlines are completely water -tight to prevent infiltration of groundwater into the system, and (b) the system is installed to prevent freezing of the gravity sewerlines. 7. The engineer and Garfield County Department shall be notified when construction commences and kept abreast of the construction progress so that sufficient inspections can be performed to assure conformance with this report. 8. It is the contractor's responsibility to verify all locations of utilities and setbacks that may be affected by the installation of the septic system. Verification of all utility locations shall be made with the appropriate utility company. 9, Substitution of materials (i.e., pipe, tanks, etc.) is acceptable provided verification and acceptance by the engineer and the Garfield County Building Department is made. As you can gather from reading this report, we are leaving the specifics, (i.e., exact location, grades and elevation) of the installation of the system to the contractor and /or yourself. It is important to note, however, that the location of the septic system must be provided in the same general location of where the percolation tests have been performed. In essence, if the septic SCHMUESER OORDON MEYER, INC. system is located on a site different site than where the percolation test was taken, verification of the pert rates must be made by SGM prior to final installation of the leach field. If it is determined that the information as provided is not of sufficient detail for your contractor and /or yourself to construct the system, please notify us immediately and we can provide a detailed construction plan for the system. To accommodate such a detailed construction plan, SGM would have to coordinate with yourself collection of detailed topography in the area of the proposed septic system. Aside from the comments just made, I hope this information is of sufficient detail to accommodate your needs in installing this septic system. If you have any questions or comments, please don't hesitate to call. Sincerely, \ vpounoauanui SCH UESER G I RDON MEYER, INC. ``" p� . ..
