The analysis and design were reviewed and completed by I. Kelly Close, P.E. (CO 44870). Kelly holds a certificate in the NAWT Designer course. The phone number for Sunshine Engineers, LLC is 720-248-7434 and email contacts for William and Kelly are willianri@sunshine-engineers.com and kelly sunshine -en gineerscoin Prior to doing the field investigation, we conducted research including review of the mapping, review of aerial photos of the property, information available on the Weld County Assessors website and Health Department website, review of the flood mapping and review of the USDA soil mapping, a copy of which is attached to this report. LOCATION The property on which the onsite wastewater treatment system is to be constructed is known as 7050 Elm Street, Lot 9 of the Enchanted Hills subdivision in Weld County, Colorado. EXISTING CONDITIONS/PROPOSED CONSTRUCTION The site is currently occupied by a residence and several agricultural outbuildings. The residence is served by an existing septic system that is permitted and is west of the residence. Due to the difficulty of modifying landscaped areas and required modification and addition to the existing septic system, and the certainty of requiring an electrical pump and a new warning device, the plan is to construct a new onsite wastewater treatment system east of the residence to accommodate a proposed shop with a 2 -bedroom Additional Dwelling Unit (ADU), The shop/ADU is proposed to be located southeast of the existing residence. The area for the proposed new soil treatment area for the shop and ADU is east of the existing residence and has been sited north of the proposed shop. This is illustrated on the site plan, attached to this report. The area is gently sloping with a slope of about 2%, which is generally to the north. if the plans are different, we should be notified so that our recommendations can be reviewed and revised if necessary. www.su nsh ine-e ngi neers. co m 1 9205 Galway Rd, Boulder, CO 80303 I (720) 248-7434 Page 2 Project 22126 SOILS CONDITIONS Two test pits were completed adjacent to the area proposed for the new soil treatment area. The test pits revealed a topsoil layer about 1 foot deep which was underlain by sandy loam which continued to the full depth of the test pits of just over 8 feet. GROUNDWATER Neither groundwater nor signs of a seasonal groundwater table were noted in the test pits right after they were dug in December of 2021 nor when they were checked again on February 14, 2022, to the full depth of the test pits of over 8 feet. Therefore, groundwater should not be a design consideration. PERCOLATION TESTS Percolation testing was not performed for this design. VISUAL AND TACTILE ANALYSIS We performedvisual and tactile analysis of the proposed soil absorption zone, which is the layer below the topsoil and that continues to the full depth of the test pits of over 8 feet. The visual and tactile analyses revealed that the material was a sandy loam with a USDA soil structure type of granular and a USDA soil structure grade of moderate. Therefore, this indicates that the use of a soil type 2 is appropriate for this design, LONG TERM ACCEPATANCE RATE (ITAR) DETERMINATION The long term acceptance rate (LTAR) was selected by use of Table 30-10-1 in the Weld County On -site Wastewater Treatment System regulations. This was determined to be 0.60 gallons per day per square foot. WATER SUPPLY The water for the residence and shop will be supplied by a water district. There are no other known wells within 100 feet of the area proposed for the new soil treatment area. Therefore, the offset between wells and the soil treatment area should not be a design consideration. The offset from any new water line from the septic system components must be maintained. The offsets are are listed in table 30-7-1 of the Weld County Regulations and also in the Offset Distance Table attached to this report, www.sunshine-engineerss.com I 9205 Galway Rd, Boulder, Co 80303 I {720) 248-7434 Page 3 Project 22126 DESIGN OF THE PROPOSED SYSTEM Details of the proposed system, including a site plan and a typical section of the proposed sewage disposal facility, are shown elsewhere in this report. The design of the onsite wastewater treatment system is based on criteria established by the Weld County Health Department onsite Wastewater Treatment System Regulations. The proposed design provides for an absorption bed as part of the septic system. The system design is based on the following assumptions. Base Size Calculation (Table_.30- -1) 1. Two bedrooms 2 persons per bedroom for the first 3 bedrooms 2. Daily flow Daily flow 3. Design LIAR 4 persons 75 gal/person/clay 75x4 300 gallons per day 0.60 gal/clay/5f The required base surface area 300/M60 of the absorption bed Soo square feet Table 30-10-2 Size Ad°ustment We are designing this system utilizing gravity flow and an absorption bed. The Table 30-10-2 size adjustment multiplier for this combination is 1.2. The required surface area of the absorption bed utilizing gravity delivery Table 30-10-3 Size Adjustment ISBN 500* 1.2 600 square feet We are designing this system assuming that infiltratorchambers will be used for the distribution media. The Table 30-10-3 size adjustment multiplier for this is 0.70. www.sunshine-engineers.corn I 9205 Galway Rd, Boulder, CO 80303 N (720) 248-7434 Page 4 Project 22126 The required surface area of The absorption bed utilizing chambers 600 *0.7 420 square feet Therefore, the total required field area has been determined to be 420 square feet. We are assuming the use of Quick 4 chambers, which have an effective size of 3 feet wide by 4 feet long, for a total effective area of 12 square feet per chamber. This means that a minimum of 35 chambers will be required. For this site, we recommend a soil treatment area that is 12 feet wide (4 chambers wide) by 36 feet long (9 chambers long). This provides a total area of 432 square feet and with a total of 36 chambers. These dimensions exceed the minimum size requirement and do not include the end caps. OTHER DESIGN CONSIDERATIONS A 1000 -gallon (minimum), two compartment septic tank is required for a two -bedroom residence. Since this system will be separate from the existing septic system, a new tank will need to be installed. We understand that an Infiltrator IM -1060 tank is preferred and this tank is acceptable. A cut sheet for this tank is attached to the back of this report. The area proposed for the new soil treatment area appears to be downslope from the proposed shop and ADU and gravity delivery to the soil treatment area is anticipated. We recommend that the installer expose all of the components and determine elevations prior to the construction. If it is found that gravity flow to the new soil treatment area is not possible then a lift station will be required. Attached to this report is a drawing that illustrates our recommendations for the lift station, if necessary. It is debatable whether this is a new or a replacement system, since there is an existing system on this site, but not for the proposed structure, which could limit the width of the new soil treatment area. However, we have designed and illustrated the system as a maximum of 12 feet wide, which is allowed. The location of the existing septic field is far to the northwest of this proposed system, and so it will not be encountered. However, if an historically undocumented field is encountered and the new soil treatment area overlaps the old field, the existing field materials and any contaminated soil must be removed and disposed of appropriately It is possible that the space between the proposed shop and ADU and the new system could be used as a driveway access. If this is used as a vehicle access that crosses a sewer line, then per code, the crossing will either need to be encased or constructed using schedule 40 pipe or pipe of equivalent or greater strength. www.sunshine-engineers.com 1 9205 Galway Rd, Boulder, CO 80303 l (720) 248-7434 Page 5 Project 22126 Please note that the location of the septic tanks and the shape and orientation of the soil treatment area are considered to be schematic. The tank location may be altered and the shape and location of the soil treatment area may be altered as long as the soil treatment area is constructed in the area of the test pits and in compliance with all County Health Department regulations. Since this is a fully infiltrating field it may be backfilled with the better portions of the site soils. We recommend that the field area be covered with a minimum of 4 inches of silty topsoil and seeded with a native pasture seed mix. Please note that the Weld County Health Department regulations require a minimum total cover of 8-10 inches atop the fabric barrier (which separates the distribution layer from the soil cover.)

Where these Drawings and Specifications are more restrictive than local codes and regulations, the Drawings and Specifications shall be followed. Notes on the drawings and/or requirements of the design section of the report shall take precedence over the standard Drawings and Specifications. CHANGES IN OR DEVIATIONS FROM DRAWINGS AND SPECIFICATIONS Changes in the Drawings and specifications may be permitted according to the following provisions: 1. The change does not violate any code or regulations. 2. The request for a change is submitted to the Owner or authorized representative of the Owner prior to construction. The change is approved by the Owner or their authorized representative. 4. The change is approved in writing by the Engineer and an authorized representative of the Health Department. MATERIALS Materials used in the construction of the septic tank and absorption field shall be durable, new, sound, and not subject to corrosion. Gravity pipe and absorption field pipe shall be 4 -inch, minimum, unless otherwise indicated. PIPING The building sewer leading to the septic tank shall be laid with a minimum fall of 1/8 -inch per foot and preferably 1/4 -inch per foot. Bends should be limited to 45 -degree "Us" or long sweep quarter bends. Sewer pipe shall be gasketed PVC gravity sewer pipe ASTM D3034 (SDR-35) or solvent weld PVC ASTM 2729. www.sunshine-engineers.com I 9205 Galway Rd, Boulder, CO 80303 I (720) 248-7434 Page 7 Project 22126 The absorption field piping, where applicable, shall be perforated PVC ASTM 2927, or white rubber sewer and drain pipe, Spec. CS -228-61 or Fed. Spec. WWP 00380 having 1000 pound crushing strength. Between each trench or bed in the case of a serial -type system, or at distribution pipe bends, standard pipe fittings which will form rigid watertight joints shall be used. Pipe in beds and trenches shall be installed level. The terminal ends of all lines shall be capped unless looped or air vented. At least one capped inspection pipe shall be provided in each trench or section of the bed. If small diameter pump line plastic pipe is required, it shall be polyethylene plastic pipe (Commercial Standard CS 255-63). When plastic pump lines are used, no splices or fittings should be installed in the line except at its connection to the pump. All pipe, pipe fittings, and pipe joints shall be in accordance with the Uniform Plumbing code, and the manufacturer's recommendations. PUMP For this system we recommend a Liberty, 0.50 horsepower pump, model FL -5o, or equivalent, if a pump is required. ABSORPTION FIELD The absorption field shall be constructed in accordance with the lines, grades, and details given on the drawings. There shall be undisturbed earth or compacted fills retaining all septic tank effluent. All fills or dikes are subject to inspection and approval by the design engineer. Open trenches shall be protected from surface runoff to prevent the entrance of silt and debris. All smeared or compacted surfaces of the trench or bed shall be raked to expose the natural texture of the soil. All loose material shall be removed from the trench before the gravel is placed. Over -compaction of the absorption field by vehicular traffic or other means shall be prevented. BACKFILLING AND SITE GRADING All major grading shall be accomplished before construction of the sewage disposal system is begun. Backfill around the septic tank shall be with moist soil hand tamped sufficiently to prevent future settlement. Positive drainage from and around the bed must be provided by sloping, mounding, ditching and berrning as shown on the drawings. www.su n sh in a -engineers ,corn I 9205 Galway Rd, Boulder, CO 80303 I (720) 248-7434 Page 8 Project 22126 MAINTENANCE AND OPERATION CLEANING Septic tanks should be cleaned before too much sludge or scum is allowed to accumulate. If either the sludge or scum approaches too closely to the bottom of the outlet baffle, or other device, particles will be scoured into the disposal field and will clog the system. Eventually, when this happens, liquid may break through to the ground surface and/or the sewage may back up in the plumbing fixtures. When a disposal field is clogged in this manner it is not only necessary to clean the tank but it also may be necessary to construct a new disposal field. Tanks should be inspected at least once a year and cleaned when necessary. Cleaning may be necessary every two to five years. Although it is difficult for most persons, actual inspection of sludge and scum accumulations is the only way to determine definitely when a given tank needs to be pumped. When a tank is inspected, the depth of sludge and scum should be measured in both compartments. The tank should be cleaned if either (a) the bottom of the scum mat is within approximately 4 inches of the bottom of the outlet baffle, or (b) sludge comes within 8 inches of the bottom of the outlet baffle. Scum may be measured with a pole to which a flat board has been attached, or with any device that can be used to feel out the bottom of the scum mat. The pole is forced through the mat, then turned and raised until resistance from the bottom of the scum is felt. With the same tool, the distance to the bottom of the outlet baffle can be found. There are firms which conduct a business of cleaning septic tanks. An Internet search may be consulted to obtain this service. Cleaning is accomplished by pumping the contents of the tank into a tank truck. Tanks should not be washed or disinfected after pumping. A small residual of sludge should be left in the tank for seeding purposes. When a large septic tank is being cleaned, care should be taken not to enter the tank until it has been thoroughly ventilated and gases have been removed to prevent explosion hazards or asphyxiation of the workers. CHEMICALS In general, the addition of chemicals to a septic tank is not recommended. The functional operation of septic tanks is not improved by the addition of disinfectants or other chemicals. Some 1,200 products, many containing enzymes, have been placed on the market for use in septic tanks, and extravagant claims have been made for some of them. As far as is known, however, few have proven helpful in properly controlled tests. Frequently, however, the harmful effects of ordinary household chemicals are over -emphasized. Soaps, detergents, bleaches, drain cleaners or other material, as normally used, will not have appreciably adverse effects on the system. However, as both the soil and essential organisms www.sunshine-enginee rs, corn 9205 Galway Rd, Boulder, CO 80303 (720) 248-7434 Page 9 Project 22126 might be susceptible to large doses of chemicals and disinfectants, moderation should be the rule. Waste brines from household water -softener units have no adverse effect on the action of the septic tank, but may cause a slight shortening of the life of a disposal field installed in a structured clay -type soil. MISCELLANEOUS Roof drains, foundation drains, and drainage from other sources producing large intermittent or constant volumes of clear water should not be piped into the septic tank or disposal field. Such large volumes of water will stir up the contents of the tank and carry some of the solids into the outlet line; the disposal system following the tank will likewise become flooded or clogged and may fail. Drainage from garage floors or other sources of oily waste should also be excluded from the tank. Disposal fields of either the absorption or evapotranspiration type must not be used for driveways or parking, or any use which might over compact the area. Drawings and designs showing the location and other information regarding the septic tank and disposal system should be retained by the property owner.
