Kjell Mitchell 215 Dolores Circle Glenwood Springs CO 81601 RE: Lot 8, Westbank Mesa Subdivision Dear Kjell: In response to your letter of May 7, 1997, SGM, in conjunction with yourself, Randy Crenshaw and CTL/Thompson have completed the investigation and evaluation of the existing septic system which is intended to serve your residence on Lot 8, Westbank Mesa. As you had indicated in your May 7, 1997, correspondence to myself, you had been experiencing problems in the form of gray water seeping out of the top of the (each field and septic tank. Subsequent to receiving your letter on May 8, Randy Crenshaw and 1 met with yourself on site to expose certain elements of the system to try to determine the cause of the observed problems. I have attached a sketch which summarizes the dimensional characteristics of the system as installed. Generally, based upon our observations of May 9, 1997, it appeared to me that the system had completely failed in its ability to discharge effluent into the surrounding native soils. Subsequent to making this observation, CTL/Thompson was contacted to perform additional percolation testing in the area of the infiltrators so that verification of the original design percolation rate could be made. On May 16, 1997, I received a phone call from John Mechling, of CTL/Thompson, indicating that they had completed the percolation testing and that the design percolation rate originally utilized (of 12.3 mpi) was still acceptable. In fact, John indicated that the percolation rate determined from the testing performed during the week of May 12 through 16, indicated that a faster rate of 10 mpi is also appropriate. Having obtained the as -built geometric configuration of the various components of the septic system, as well as having obtained the information regarding the percolation rates on the lot, the following problems have been identified which have led to the failure of the system: 1. The infiltrators are sloping from the inlet end to the opposing end as much as 4" to 6 ". Proper operation of the infiltrators would require that a "flat" installation be provided. 2. Infiltrator trenches are to be spaced at 10 -foot minimum spacing. The observed spacing was measured to be too close - at five feet. Closer spacings (as observed in the field) tends to make the system operate as a "bed -type system ", not a trench -type system. This would require the leach field to be sized some 30% larger than what was designed for and what was installed. May 19, 1997 Mr. D. Kjell Mitchell Page 2 3. The inlet end of the distribution box is 3 1/4" lower than the inlet of the infiltrators. The distribution box, in fact, needs to be "higher" than the trenches. The pipe from the box should slope at a 2% (or '/" per foot) slope toward the trenches, not away from the trenches. 4. The distribution box is out of level by 2 -5/8 ". This causes unequal distribution into the infiltrators and, therefore, causes the system to operate improperly and it cannot utilize the full square footage of the infiltrator trenches provided. 5. Either the septic tank or the distribution box are the low point of the system as it currently exists. Further exploration of the septic tank outlet end would be required to ascertain what specifically is the lowest component of the system. However, neither component should be the lowest point of the system. Having these components in this configuration could lead to improper operation of both the septic tank and the distribution box in that floatable waste would bypass tees and baffles in the system and would allow these floatable wastes to enter into the infiltrator trenches, these would obviously accumulate and create problems in masking off the infiltrative surface. 6. Another potential problem observed that could be creating problems with the system is that it is requiring additional hydraulic loading to the system, was that the roof drain as located in relationship to the septic tank access hatch may, in fact, be depositing rain water or runoff water into the system. This would create additional hydraulic loading to the system and, thus, creates further burden on the system. On August 17, 1994, SGM prepared a report for Randy Crenshaw regarding the outline specification design for Lot 8, Westbank Mesa Subdivision, Garfield County, Colorado. I had previously provided you with copies of this report. Based upon the percolation testing, and the fact that the house design had remained unchanged, we would recommend that the repair of the septic system utilize this report. In essence, a re- design of the system is not necessary, rather, a reconstruction of the system to match the requirements of this report would be. The contractor originally installed a 1500 gallon septic tank for this site which is more than adequate as far as septic tank capacity is concerned. However, from the septic tank to the leach field, we would recommend that a thorough investigation of each component of the system be evaluated to assure that the septic tank is the highest component of the system, followed by the distribution box and then followed by the infiltrator trenches. In essence, as Y. " per foot slope from the septic tank to the distribution box is required. Accordingly, from the distribution box to each infiltrator trench, an additional '/ " per foot on the pipe is required. Finally, the infiltrator trenches should be laid flat. Laying the infiltrators flat will assure full utilization of each square foot of the infiltrator trenches under the design flow conditions. As SCHMUESER GORDON MEYER, INC. May 19, 1997 Mr. D. Kjell Mitchell Page 3 far as reconstruction or reconfiguration of the infiltrator trenches is concerned, one could attempt to re- install the infiltrators in basically the same locations as they now exist by removing the existing infiltrators along with contaminated soils such that the infiltrators can then also be laid flat back into their original position. However, the middle leg of the infiltrators (where they were spaced at five feet on center) would need to be removed in its entirety and the closest spacing of 10 feet on center would need to be assured. An alternative to reconstructing the infiltrator trenches in their same location would be to install new trenches to the north and downhill of the existing infiltrator trenches. This alternative would have its advantages in that the construction of the new trenches would not have to consider problems of handling those soils that have been supersaturated from the existing system. It would make excavation and backfill of the system and repair of the system much quicker and cleaner. In summary, it is our position that if you reconstruct and reconfigure the system in accordance to the outlined specifications provided in our August 17, 1994, letter to Randy Crenshaw, the system will provide adequate disposal effluent in accordance with Colorado Department of Health criteria. • Upon review of this letter, if you have any questions, comments, or need further assistance, please don't hesitate to call.

This work follows previous foundation work performed by SGM (Job #94090). With that previous structural /foundation work, it has been determined that the house is a 4- bedroom residence. In addition, we are in receipt of a report prepared by CTL/Thompson identifying the percolation rate for Lot 8, West Bank Mesa. In CTL/Thompson's test results, we have identified the average percolation rate for this lot to be 12.3 mpi. We have attached a copy of the percolation test results as part of this report. Please note that in determining the average percolation rate for this site, we have not included the highest and lowest instantaneous perc rates in our averaging calculations. With percolation test results, we have also attached a copy of boring Togs prepared by CTL/Thompson. A summary of the boring logs identified that the septic system (or leach field system) will be installed in clayey, sandy, stiff to very stiff, slightly moist to moist and brown soil. At lower depths (5' plus), a layer of sand, clayey to silty, medium dense to very dense, slightly moist to moist brown soil is present. Based upon the percolation test results and the soil borings, it appears that a standard leach 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 ISDS 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. August 17, 1994 Mr. Randy Crenshaw Page 2 Please note that the septic tank must be located at (east five feet away from the residence. In addition, the effluent line leaving the house and going 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 at a minimum ASTM 2729 PVC pipe of minimum 4" diameter. The grade of the pipe must be at a minimum of '/ " 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 'Y4" 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. Soils profile Togs. SCHMUESER GORDON MEYER, INC. August 17, 1994 Mr. Randy Crenshaw Page 3 4. Percolation test results. 5. Schematic plan view of septic system installation. 6. Sketch of the standard infiltrator chamber. 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. SCHMUESER GORDON MEYER. INC. August 17, 1994 Mr. Randy Crenshaw Page 4 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 that identified with the boring logs of CTL/Thompson. In essence, if the septic system is located on a site different than where the percolation test was taken, verification of the perc rates must be made by either CTL/Thompson or 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, SCHMUESE• GORDON MEYER, INC. owl, I {! 1/4, 1/ 4 :140901 on, P .E. ' ,j_ ` °�, ', C`�`",.
