The property is located outside of Rifle, in an area where OWTSs and wells are necessary. The existing OWTS serving the residence has failed and will be replaced. Records from Garfield County were obtained and Garfield County Building and Sanitation Department Permit 2520 documents this system. There is an existing 1250 -gallon Copeland concrete septic tank and 47 Standard Infiltrator® chambers. The permit was finalized on January 15, 1996. The system was sized to accommodate 4 -bedrooms. SITE CONDITIONS A 4 -bedroom, single-family residence presently exists and is utilizing an existing OWTS, which is experiencing saturated conditions. There is also a shop with no plumbing on the property. There is a private well located on the property located greater than 100 -feet from the proposed soil treatment area (STA). A ditch on the property is greater than 50 -feet from the proposed STA. This ditch will be re- aligned or placed in a culvert in areas adjacent to or up -gradient of the proposed STA to alleviate the high groundwater in the area of the proposed STA. CALCULATED WASTEWATER FLOW The proposed OWTS will be sized to accommodate a 5 -bedroom residence to allow for an addition to the existing residence. Plumbing, such as a toilet and sink, may be added to the shop in the future for use by residents of the property. Calculated flow is 600 gallons/day. SUBSURFACE The subsurface was investigated on August 28, 2014 by digging two 8 -foot soil profile test pit excavations (Test Pit #1 and #2). The area had experienced a significant amount of rain in the days prior to and including the day of the subsurface investigation. A visual and tactile evaluation of the soils was performed. Materials in the Test Pits consisted of very moist, brown, granular, sandy silt. Groundwater was encountered at 4.5 - feet in Test Pit #1 and at 4.0 -feet in Test Pit #2. A waterline to a ranch hydrant near Test Pit #2 was severed during excavation, potentially contributing to higher water levels in Test Pit #2. The original OWTS permitted by Garfield County documents a percolation rate of 34 MPI. A long term acceptance rate (LIAR) of 0.5 gallons per square foot will be used to design the OWTS, in accordance with Table 10-1 Soil Type 2A presented in the Garfield County On -Site Wastewater Treatment System Regulations, effective June 30, 2014. Test Pits observed August 28, 2014 PROPOSED OWTS DESIGN The OWTS design is based on 5 -bedrooms. A wastewater flow of 600 GPD will be used. The STA will be sized on a silt loam material with a granular structure (Soil Type 2A), dosed to gravelless chamber beds. Minimum septic tank sizing criteria requires 1500 -gallons, adding a minimum 250 -gallons for pump capacity. Minimum STA sizing requires 924 square feet of infiltrative area and 77 'Quick 4' Infiltrator® chambers. The existing OWTS will be properly abandoned. A new 1250 -gallon, two-compartment Roth® septic tank, followed by a new 1250 -gallon, two-compartment concrete septic tank with an Orenco® Biotube pump vault and PF3005 pump in the second compartment. Effluent will be pumped through a 1.5 -inch diameter pump line to a new distribution box, accessible from grade. From the distribution box, effluent will gravity flow to four new gravelless chamber beds, each with 2 rows of 11 'Quick 4' Infiltrator® chambers for a total of 88 'Quick 4' chambers and 1056 square feet of infiltrative area. Inspection ports must be placed at the beginning and end of each bed. These ports may be cut to grade and covered with a valve box for access. Chambers will be installed at native grade in order to obtain a 4 -foot separation to high groundwater. Backfill over the chambers must be a minimum depth of 1 -foot over the chambers, graded to deflect precipitation. Backfill over the STA must be uniform and granular with no material greater than minus 3 -inch. Native vegetation over the STA must be established to prevent erosion. The STA must be protected from any traffic from the gravel drive. A minimum 2% fall must be obtained on the sewer line from the house to the septic tank. Anchoring of the septic tanks may be necessary. A minimum 1% drain back must be obtained from the distribution box to the pump chamber to prevent freezing in the pump line. The ranch hydrant and water line must be removed or relocated. The hydrant should be placed at least 100 -feet from the STA and the water line must not come within 25 -feet of the proposed STA. The component manufacturers are typical of applications used by contractors and engineers in this area. Alternatives may be considered or recommended by contacting our office. Construction must be according to Garfield County On -Site Wastewater Treatment System Regulations, the Septic Permit provided by Garfield County Building Department, and this design. REVEGETATION REQUIREMENTS An adequate layer of good quality topsoil capable of supporting revegetation shall be placed over the entire disturbed are of the OWTS installation. A mixture of native grass seed that has good soil stabilizing characteristics (but without taproots), provides a maximum transpiration rate, and competes well with successional species. No trees or shrubs, or any vegetation requiring regular irritation shall be plated over the area. Until vegetation is reestablished, erosion and sediment control measures shall be implemented and maintained on site. The owner of the OWTS shall be responsible for maintaining proper vegetation cover. OPERATION INFORMATION AND MAINTENANCE The property owner shall be responsible for the operation and maintenance of each OWTS servicing the property. The property owner is responsible for maintaining service contracts for manufactured units, alternating absorption systems, and any other components needing maintenance. Geo -fabrics or plastics should not be used over the absorption area. No heavy equipment, machinery, or materials should be placed on backfilled absorption area. Livestock should not graze on the absorption area. Plumbing fixtures should be checked to ensure that no additional water is being discharged to OWTS. For example, a running toilet or leaky faucet can discharge hundreds of gallons of water a day and harm a STA. The homeowner should pump the septic tank every two years, or as needed gauged by measurement of solids in the tank. Garbage disposal use should be minimized, and non -biodegradable materials should not be placed into the OWTS. Grease should not be placed in household drains. Loading from a water softener should not be discharged into the OWTS. No hazardous wastes should be directed into the OWTS. Mechanical room drains should not discharge into the OWTS. The OWTS is engineered for domestic waste only. ADDITIONAL CONSTRUCTION NOTES If design includes a pump, air release valves and weep holes must be installed to allow pump lines to drain to minimize risk of freezing. Excavation equipment must not drive in excavation of the STA due to the potential to compact soil. Extensions should be placed on all septic tank components to allow access to them from existing grade. Backfill over the STA must be uniform and granular with no material greater than minus 3 -inch. INSTALLATION OBSERVATIONS CBO, Inc. must view the OWTS during construction. The OWTS observation should be performed before backfill, after placement of OWTS components. Septic tanks, distribution devices, pumps, dosing siphons, and other plumbing, as applicable, must also be observed. CBO, Inc. should be notified 48 hours in advance to observe the installation. LIMITS: The design is based on information submitted. If soil conditions encountered are different from conditions described in report, CBO, Inc. should be notified. All OWTS construction must be according to the county regulations. Requirements not specified in this report must follow applicable county regulations. The contractor should have documented and demonstrated knowledge of the requirements and regulations of the county in which they are working. Licensing of Systems Contractors may be required by county regulation. Please call with questions.
