John Fish ,,·-C!O Joseph Edward P. 0. Box 3554 Aspen, CO 81612 RE: Individual Sewage Disposal System Design for Fish Residence, 0204 Flying Fish Road, Garfield County, Colorado SE Job No. 98099.01 Dear Mr. Edward; J January 6,J1 999 / I Attached herewith is the revised report and design for the subject site improvements per your request. We have made some adjustments to our design based on the new information regarding the proposed improvements you provided us in addition to the previous report. Existing Sjte Conditions: The subject site is located adjacent to the Roaring Fork River at 0204 Flying Fish Road in Garfield County, Colorado. The existing main house has three bedrooms. Water is supplied by a well on the property next to the existing house near the southeast comer of the property. The existing ground surface near the area for the proposed septic system slopes to the southwest at a 0.30 % grade. The finished floor elevation for the current residence is 6324.2 feet (msl) and the nominal elevation of existing ground at the location of the proposed leach field is 6325.0 +/-(msl). Proposed Site Conditions: The current owner intends to construct additions to the existing house, yet maintain the living quarters at three bedrooms. Other improvements to the property include building a separate garage with living quarters equivalent to two bedrooms and a separate accessory structure. The total number of bedrooms for the design of the proposed system will be five ( 5) unless noted otherwise. Subsurface Conditions: Attached herewith are the results of the subsurface investigation and percolation tests conducted by Hepworth-Pawlak Geotechnical, Inc. dated September 16, 1998. The subsoil encountered at the site consists of about two (2 ') feet of compacted backfill above very clayey sands underlain with dense sandy gravel and cobble alluvium of about two (2') feet depth. The groundwater table was encountered at about two feet below the ground surface in the profile pit. Due to the slow absorption rates and high groundwater table, the system will need to be elevated, then bedded with acceptable soils imported to the site. 502 Main Street· Suite A3 ·Carbondale, CO 81623 • (970) 704-0311 • Fax (970) 704-0313 SOPRIS ENGINEERING • llC civil consultants Final Svstem Design: Page2 Fish Prope;:t)' SE Job No. 98099.01 A site plan is provided to detail the various co mponents of the proposed sewage disposal system. Please note that the location of the proposed leach fie ld system is required to be outside the floodplain. The new field must be constructed as a mound system since the water table is so close to the surface of the ground. The following pages detail the technical criteria utilized in design of the proposed system. Design Criteria: Pmposed res idence is a 3 bedroom house with a detached garage having 2 bedrooms above the garage. The design flows are calc ulated as follows: Residence unit -3 bedrooms @ 2 person /bedroom = 6 person Garage unit -2 bedroom @ 2 person I bedroom = 4 person Total #of occupants = 10 person From the Garfield County I. S . D. S. Regulation ; Max. design flow (Q) =#of people x 1.5 x (avg. flow)gal/person/day x 75 gal/person/day Q = 10*75*1.5 = 1125 gal/day Septic Tank Design: Main House and Garage Unit Q = 10*75*1.5 =1125 Vo lume (V) of tank= Design Flow* 1.25 (30 hour retention time) . v = 1125 cral/day * 1.25 = 1406 gallons 00 I ta t e a a e a ai hou e. Percolation Test Results: Attached herewith are the results of the subsurface investigation and percolation tests conducted by Hepworth-Pawlak Geotechnical, Inc. dated September 16, 1998. As mentioned above, the groundwater tab le was encountered at a bout two feet below the ground surface in the profile pit. Three test holes were used with varying absorption rates with the first test hole measuring IlQ. rate of absorption, yet the other two test holes were measured at 90 minutes per inch. The results of the percolation test indicated the subsurface soils are unacceptable for a conventional absorption field system without modifications to the soil. Garfield County Regulations will not accept absorption rates longer than 60 minutes per inch for design of conventional leach fie ld systems without modified soils. Also, Regulations require the bottom of the leach field system to be a minimum four feet abo~e water tabl~. Therefore, an elevated or Mounded Soil Abso rption Disposal System is recommended for this site. Absorption Field Disposal System Design: A (SF) = S))S * -Vt : where A= Area; Q = flow (gal/day) .Yt = square root of time· of absorption rate (min./ inch) This design will give a recommended minimum absorption field area: A= (1125/5) * °'190 = 2135 sq. ft. Page 3 Fish Property SE Job No. 98099.01 Thus, using imported sandy loam soil yields the minimum area: A=Q/LTAR = 1125 /0.72 = 1,563 sq. ft . Use: Minimum 36' x 60' absorption field or dimensions to obtain 2135 sq. ft. minimum. Site Improvements Layout: In retrospect of t_he current conditions, all septic tank and sewage lines must be watertight for reasons that much of the proposed septic system will be placed at or below the water table. A dosing tank of 600 gallons capacity is recommended due to the size of the absorption area and have automatic liquid level controls. A grinder pump will be needed to pump sewage to the elevated distrib ution field and sufficiently sized to maintain a discharge velocity of 5 feet per second. The dosing tank will be fed from the septic tank. The tank must be watertight therefore, it is recommended to install a one piece septic tank unit to prevent groundwater infiltration into the septic system. General Notes: l) All materials and installation practices shall conform to the Garfield County Individual Sewage Disposal Regulation. 2) All sewer lines in the system shall be Schedule 40 or SDR-35 PVC unless specified otherwise on the plans. • 3) The contractor shall ensure that the concrete septic tank and sewer lines are completely watertight. 4) The bed area must be protected to prevent damage from vehicular or livestock traffic and must be crowned to divert drainage runoff away from the bed. 5) The contractor shall not eXC(;l.Vate to a depth greater than two feet (2 ') at any one location within the site of the proposed bed. --- 6) The mound shall be planted (sod or mulch seeding) with suitable vegetative cover. 7) The sand material utilized in the bed shall have an effective size between 0.25 mm and 1.00 mm. The uniformity coefficient shall be 4.0 or less. 8) Add two-way cleanouts on each service line from the house and garage. 9) Livestock should not be confined in the field area. l 0) All septic and dosing tanks will require anchoring where groundwater is present. . ~ ---;:--._ ---- Page4 Fish Property SE Job No. 98099.01 Our design and recommendations are based upon data supplied to us by others.

Sopris Engineering inspected the new-mounded sand and gravel absorption bed during construction prior to final backfill and after construction was completed. The uew-mounded absorption bed was constructed in general compliance with the perm itted design. The system constructed on site was designed and built to serve the needs of the 3-bedroom house and the two -bedroom garage unit. Sopris Engineering perfonned visits to inspe ct the system components, the material specifications and the distribution components associated with the OWS. The mounded sand and gravel absorption System, a 1500-gallon dual compartment concrete septic tank, a 600- ga ll on dosing tank ., pump, controls and associated piping was installed in accordance .with County and State Regulations, the design specifications presented in the Sopris Enginee ring design draw i·ng and the report dated January 6, 1999 . Th e mounded absorption field was constmctcd in a lo cation near the north lot line outs ide of the delineated 100-year flood plain. The mounded sand and gravel absorption field was constructed with a perforated distribution pipe array installed level in a gravel layer ovel'l y ing a layer of filter sand for secondary treatment . Suitable on site and pit nm type material fill was placed as needed below the sand filter layer to raise the level of the mounded bed to an appropriate height abo ve the seasonal high ground water and the l 00-year flood plai n level. Monitoring wells were installed on both ends of the field. The exposed soils after grubbing were suitable and consistent across the fie ld. The distribution gravel was covered with filter fabric and a minimum of 12 inches of backfill was placed to the finish grades that have been shaped to provide draina ge off thc bed . Appropriate grading around the mound is complete with approximate side slopes at 3: t . The effluent is pumped from the dosing tank through a pressurized 2" transport pipe that connects to a 4-inch manifold header pipe that splits the flow through the 6 perforated distribution lines installed in the mounded field. The minimum setback distances have been maintained. A concrete dosing basin manhole stru cture was installed with a simplex sewage pump dosing system. with automatic controls . OWS Operation and Maintenance All components of the engineered OWS shall. be inspected on a regular basis and be properly maintained. The re establishment of vegetative cover over the field and responsibility for operation, inspection and maintenance of the system will remain with the Lot Owner or the owners repres entative. The owner shall periodically inspect the OWS and perfo1m all maintenance and repairs as necessary to ensure that the system is in good operating condition and perfonning as designed. / 502 Main Street• Suite A3 •Carbondale , CO 81623 • (970) 704 ·0311 ·Fax (970) 704-0313 SOPRIS ENGINEERING • llC civil consultants 05/25/2007 13:20 970-704-0313 SOPRIS ENGINEERING PAGE 07 Andy Schwaller SE Job No. 98099.0J June 22, 2007 Page2 The OWS should require minimal maintenance. Several factors influencing the need for maintenance include: actual wastewater flows versus design flows, the volume of kitchen/domestic waste (excluding human waste and toilet paper), excessive hoiisehold chemicals and other toxic liquids. The tank, sanitary tees and effluent filter should be visually inspected bi-ruu1ually for clogging debris, damage, leaks, or other potential problems. ln general, for a properly utilized system, septic tanks should be pumped and inspected every 2 • 4 years. The effluent filter should be cleaned every six months and at the time of pumping. Absorption fields should be maintained with suitable vegetative cover and kept free ofroot invasive plants. Positive surface drainage away from the absorption field should be maintained. Tfyou have any question .or need any additional infonnation, please call.
