HomeMy WebLinkAboutEngineer's Inspection Report 11.09.2018November 9, 2018 CBO Inc. 33 Four Wheel Drive Road Carbondale, CO 81623 cell) 970-309-5259 carla.ostberg@gmail.com Sandy Smith Sandy.smith@sothebysrealty.com c/o Doug Kenward dougkenward@earthlink.net Onsite Wastewater Treatment System (OWTS) Inspection 3057 CR 103 Garfield County, Colorado Doug and Sandy, As requested, CBO Inc. performed an Onsite Wastewater Treatment System (OWTS) inspection at 3057 CR 103, Carbondale, Colorado on October 12, 2018. The legal description of the 18.14 -acre property is as follows: Subdivision: Section: 12 Township: 7 Range: 88 A TR IN LOT 8 AKA PARCEL B SMITH EXEMPTION There are two residences on the property; the main house and the guest house. MAIN HOUSE The OWTS serving the main house was engineered by SGM, with plans dated September 1, 2009. It does not appear that the system was permitted by Garfield County. We recommend submitting SGM's design and this inspection report, along with a completed Septic Permit Application (https://www.garfield- county.com/community-development/documents/2018/Septic-permit.pdf) to Garfield County Building Department for retro -active approval of this OWTS. According to SGM's design documents, the OWTS consists of a 1250 -gallon, two-compartment concrete septic tank with an Orenco® pumping system in the second compartment. Effluent is pumped to an automatic distributing valve (ADV). Four trenches, each with 15 `Quick 4' Infiltrator® chambers, are pressure dosed. During our visit on October 12, 2018, we inspected the septic tank, located to the south of the residence. Both lids were accessible from grade at the time of our inspection. The inlet tee was present. The outlet side of the septic tank housed the Orenco® ProPak and Biotube Effluent Filter. This filter must be cleaned annually, or as needed. We tested the pump and viewed the automatic distributing valve (ADV) cycling. We observed the air relief valve releasing some water each time the pump kicked on and recommended Valley Precast out of Buena Vista be called to check the pumping system and air relief valve. We walked the soil treatment area (STA) and observed flushing valves and inspection ports on each trench. There was a small amount of snow cover over the STA at the time of our inspection. We found no evidence of surface saturation and evidence of failure at the time of our inspection. Jerry Fleck, Service Manager for Valley Precast, inspected the pumping system after our inspection and made some changes to the wiring. This evaluation is not a guarantee of future system performance. GUEST HOUSE The guest house permit (enclosed) was provided by Garfield County Community Development Department. Information provided in the documentation appears to be "proposed" rather than documentation of the installation. We have been able to ascertain that the subject OWTS consists of a minimum 1000 -gallon, two-compartment concrete septic tank followed by a soil treatment area (STA) comprised of a minimum of 427 square feet of infiltrative area in a chamber trench configuration. Garfield County Individual Sewage Disposal System (ISDS) Permit 2470 documents the system. The system was sized to accommodate 3 bedrooms. A clean out is located on the north side of the residence. The septic tank is located to the north of the guest house. Both septic tank lids were accessible from grade. Liquid levels in the septic tank were normal at the time of our inspection. Both inlet and outlet tees were present. The outlet tee was angled upward, which is an indication that the pipe has settled as it exits the septic tank. We typically recommend an effluent filter be installed on the outlet tee; however, given the angle of the pipe currently, it would not be possible. We walked the approximate STA. No inspection ports were present. There was a small amount of snow cover over the STA. We did not observe evidence of surface saturation or failure at the time of the inspection. This evaluation is not a guarantee of future system performance. Recommendations: • GUEST HOUSE — Straighten pipe exiting septic tank and install effluent filter on outlet tee. If installed, this filter must be cleaned annually, or as needed. • MAIN HOUSE — Clean effluent filter annually, or as needed. Disclaimer: This inspection is intended only as an evaluation of the present condition of the OWTS based upon what was observed and the Licensed Inspector's expertise in onsite wastewater technology. The Inspector has not been retained to warrant or guarantee the proper functioning of the system for any period of time in the future. Because of numerous factors which may affect the operation of an OWTS, as well as the inability of the Inspector to supervise or monitor the use or maintenance of this OWTS, this report shall not be construed as a warranty by the Inspector that the system will function properly for any particular prospective buyer, and the Inspector disclaims any warranty, either expressed or implied, arising from the inspection of the OWTS or this report. The evaluation does not ascertain the impact the system is having on groundwater. Please call with questions.

The design was prepared for Individual Sewage Disposal System (ISDS) permit submittal to Garfield County Environmental Health Department (GCEHD). SITE CONDITIONS The site is on approximately 18 acres of private land. The existing house is currently served by an existing septic system that has failed. The system was put in the early 70's. The subject site is located in an area where OWTS are required. The existing system is a single chambered tank that has no distribution box and daylights to the south of the dwelling. The site will be served water by an onsite well and is located approximately 175 feet from the drain field. PROPOSED CONSTRUCTION The system has been designed to accommodate a three bedroom dwelling. In accordance with Garfield County Health Regulations, the average daily wastewater flow for a three bedroom dwelling is 75 GPD per person per day for a total of 450 GPD and 675 GPD using a 1.5 peaking factor. The field is to be constructed using Quick Four Infiltrators in a trench field. Using an average daily flow of 675 GPD and a percolation rate of 36, a total of 810 square feet of absorption field is required. In this case we have chosen to take a reduction of 30% for chambers for a total area of 567 square feet. This will be a minimum of 60 chambers. The proposed construction is 4 trenches with each containing 15 chambers. The field is to be pressure dosed through an ADV to the field. 6 SCHMUESER GORTON ENGINEERS MEYER SK SURVEYORS SUBSURFACE CONDITIONS Subsurface conditions were investigated by digging a profile hole and percolation holes with a small track hoe at the location. Subsurface conditions at the test pit consist of approximately 18 inches of organic soil underlain by brown silty clay, with the maximum depth explored of 4.5 feet. Digging refusal was encountered, however the rock was fractured allowing for percolation with no groundwater encountered. Percolation testing was performed in test holes ranging in depth from about 32 to 38 inches deep. The percolation test results ranged from 27 minutes per inch (MPI) to 40 MPI, with an average of 36 MPI. It is recommended that a design rate of 36 MPI be used. Results of the percolation tests and soils evaluation are provided as attachments. RECOMMENDATIONS The results of the investigation indicate an OWTS with septic tank, effluent pump and soil based drain field can be constructed on the site. The drain field will be of the mounded sand mound type to achieve the required 48 -inch separation between the bottom of the drain field sewer rock and the fractured bedrock. The proposed location of the OWTS is presented on Figure 2. Substitutions of components or materials will not be allowed without written approval of the design engineer. Building Sewer: Sewer pipes should be 4 -inch Schedule 40 PVC pipe installed with a minimum slope of 2% to the septic tank. Joints shall be solvent welded. Cleanouts are required 1) at the stub out from the building, within 5 -feet of the face of the structure, 2) at spacing not to exceeding 100 feet, and 3) upslope of two or more bends closer than ten feet in the sewer pipe, within 2 -feet above the upslope bend. Bends in the sewer pipe are not to exceed 45 degrees. The pipe should be properly bedded per the typical trench detail presented on the design drawings. The septic tank should; 1) be located down gradient of the building, 2) be buried with no more than three feet of soil cover over the lid, and 3) at a location accessible for pumping and maintenance at the tank. Horizontal distance from the pumper truck point of access to the tank shall not exceed 100 -feet; vertical distance from the tank to the truck shall not exceed 10 -feet. The installer must coordinate with the general contractor regarding elevation of the stub out. Septic Tanks: The tank shall be a 1,250 -gallon, two-compartment tank with an Orenco Systems, Inc. Biotube pump vault in the second compartment. The tanks and lids shall conform to current County ISDS regulations. The tanks shall be installed with watertight access risers with lids that can be secured. The effluent filter handle and float tree handle in the first tank shall extent to between six and twelve inches of the lid. The electrical control panel shall be installed on the exterior of the structure with a line of site to the pump vault riser. Controls and alarms shall be listed per UL 508. The control panel shall be an OSI 31 ETMCT Series unit. Panel shall be weatherproof and located with protection to protect against adverse weather conditions. A manufacturer's diagram of the proposed septic tank configuration is presented. Schedule 40 PVC pipe connections shall be used. No mid -baffle, flow through tanks shall be allowed. 2 SCHMUESER GORDON MEYER ENGINEERS. SURVEYORS Pumping System: The simplex pump shall be an Orenco Model PF10HH, '/2 HP, 120 Volt, and single phase pump with a Biotube Effluent Screen having 1/8 -inch screen openings. The control system shall have 3 floats: 1) High Water Alarm Float, 2) Pump ON Float and 3) Pump OFF Float. Discharge Piping: The discharge piping from the effluent pump to the drain field shall be 2 - inch diameter schedule 40 PVC pipe with solvent welded joints. The pipe shall be installed with an air pressure relief valve at the high point of the discharge piping to facilitate drainage in both directions between pump cycles. A minimum pipe slope of 1% is required from the high point to the tank. The pipe shall be properly bedded per the typical trench presented on the design drawings. Because the tanks were already set before placement of the mound, it is recommended that the transport pipe from the pumps to the ADV be covered with 2 -inch rigid foam to prevent freezing. If there will be vehicular traffic over the pipe then it is recommended that the piping be encased. Automatic Distribution Valve (ADV): The ADV shall be an Orenco Model 6404 assembly that will distribute effluent to different sections of the mounded drain field each time the pump cycles. The ADV shall be installed in a PVC riser, with fiberglass locking lid, that is large enough to allow maintenance personnel to access the valve assembly and disconnect all unions to allow removal for repair or replacement. The riser assembly shall be insulated as indicated. The ADV shall be located in the discharge pipe at a point that will allow the valve to drain both to the drain field and back to the tank. Drain field: The drain field shall be excavated to the lines and grades indicated on the design figures. It is recommended that the field be installed as shallow as possible to allow for evapotranspiration. The drain field laterals shall be 1.25 -inch Schedule 40 PVC pipe with 3/16 -inch holes on 36 -inch centers oriented as described on the design drawings. There are to be 1/8 inch holes drilled at 6 o'clock in 18 inches from both ends to allow for complete emptying after each dosing cycle. The lateral piping shall be suspended from the ceiling of the Infiltrator Quick 4 chambers as designated in the design figure with hanger material that is not nylon, and is not susceptible to deterioration from the chamber environment. Furnish and install PVC reducers at the ADV for connection to each lateral. The drain field shall be constructed with a convex top surface to divert runoff away from the field. The finished grade of the drain field area shall be configured to drain precipitation or snow melt to the constructed drain. The drain field shall be covered with a minimum of 12 -inches of soil as measured after settlement. This may mean that the drain field cover will have to be 16+ -inches when in place to allow for settlement over the freeze -thaw of a winter season. The soil of the drain field is susceptible to damage from vehicular traffic. Driving over the drain field area can compact soils and reduce the percolation rate, leading to early failure. The drain field area should be fenced and protected from the construction traffic. Vehicular movement over the drain field area during construction is not allowed. The surface of the field should be seeded after installation of the system. A seed mix approved by the Garfield County Department of Land Management shall be used. These mixes do not require irrigation and develop a growth 10 to15 inches high. No automatic sprinkler system shall be installed over the field. Vehicular traffic and livestock shall be kept 3 SCHMUESER GORDON i MEYER ENGINEERS E. SURVEYORS off the drain field. No landscaping or plastic sheeting can be used over the field, which can reduce performance of the field. INSTALLATION OBSERVATIONS The installation of the OWTS is to be observed by the design engineer. A minimum of two observations by the design engineer are required for the installation of the system. One observation of the open, excavation to examine the sub grade, and a second observation after the filter sand, drain rock and all laterals and appurtenances have been installed, but before backfilling. Pump basin installation, septic tank improvements, pump, and plumbing, as applicable, can be observed during either visit. A final observation will be required after the final electrical connection has been made prior to placing the OWTS into service. Our office should be called at 970-945-1004 to observe the installation of the OWTS at least 24 hours in advance. These observations, any repeat observations, OWTS design revisions, staking of drain fields or additional site visit requirements are not included in the scope of work of this design and will be invoiced at an additional unit rate fee. OPERATION AND PREVENTATIVE MAINTENANCE SCHEDULE The goal of an operation and maintenance is to observe the operation, and perform minor maintenance to the onsite wastewater system to allow for proper, long term functioning of the system. Septic tanks: The scum and sludge accumulation in the septic tanks should be monitored yearly. Once the cumulative scum or sludge thickness reaches 25% of the tank depth, the entire tank should be pumped. A pumping frequency 1 to 3 years at design flows. An alternative is a regular pumping frequency of every 2 years. Filter and Effluent Pumping System: The effluent filter at the septic tank discharge should be cleaned (hosed off) at the time of pumping or as needed. The effluent pumps should be checked semi-annually to ensure pumps are functioning properly, if the alarm sounds, the pumps and floats should be checked and/or serviced immediately. Drain field: The surface area around the mound is to be observed monthly for signs of failure such as Tush vegetation growth, effluent ponding, and liquid in the observation pipe. in addition, the side slopes of the drain field should be observed for signs of effluent breakout, which will manifest themselves in small rivulets of effluent flowing down the side of the drain field. General: System users must realize an onsite wastewater system is different from public sewer service. There are daily considerations such as not putting plastic or other no biodegradable material into the system_ Water use should be monitored so toilets are not allowed to leak when seals malfunction. Allowing fixtures to flow continuously to prevent water lines from freezing is not acceptable. Although the proposed system can accommodate variable flows, spreadable water use over several hours and eliminating peak 4 CHMUkSER GORDON 1 MEYER ENcINEns E. SURVEYORS flows is recommended. To illustrate the point, a malfunctioning toilet can discharge in excess of 1,000 GPD. Excessive daily loading could flood and irreparably harm the OWTS. SGM cautions against installation of a water softener that discharges to the septic tank and drain field. The chemical and hydraulic loading from the backwash of a water softener may be detrimental to the OWTS and separate drywell should be constructed for the backwash waste, if a softener is installed. The design of the OWTS is based on the treatment of domestic sewage, only. The proposed OWTS design is based on flows noted in the report. Increased flows may hydraulically or organically overload the OWTS, causing premature failure. LIMITATIONS Our investigation, layout, design and recommendations are based on data submitted. If conditions different from those described in this report are encountered, SGM should be called to observe the conditions and made design changes if necessary. If proposed construction is changed, SGM should be notified to evaluate the effect of the changes on the wastewater system. Al! construction is to be in accordance with the current ISDS regulations. Pipe type and size, burial requirements, septic tank construction, and other specifications, which are not depicted in our report, are to conform to the requirements of the ISDS regulations. The installer of the system is to be licensed by the county health department and demonstrated knowledge of the ISDS regulations and requirements. This onsite wastewater design is intended to be used only for the wastewater load specified in the drain field calculations and for the site indicated on the subject line. Any other applications of this design are not authorized by SGM. Use of this design for any other area on the subject lot than designated, on any other lot or for wastewater volumes or strengths not indicated constitutes a misapplication of the design and voids all liabilities on the part of SGM. If there are questions or we may be of further service, please call. Respectfully, SCHMUESER GORDON MEYER, INC Brian Edwards, ROWP 5 Dan Cokley, P.E.

Our recommendations are based on the percolation test we conducted, and our site visit. The percolation testing was performed at a depth of approximately three feet and in an area northerly of the proposed residence. The percolation rate recommended for design was 40 minutes per inch. We recommend that standard absorption trenches be utilized, and that they be placed as shallow as reasonable, to avoid the large rocks found at greater depth. One possible layout would be three parallel trenches separated by ten to twelve feet. The trenches should run along the contour of the land. We understand that this ISDS would serve .a single family residence with three bedrooms. Therefore, the estimated average wastewater flow would be 400 gallons per day. The design flow, per regulation, is 1.5 times the average, or 675 gallons per day. 923 Cooper Avenue • Glenwood Springs, CO 81601 Telephone: 303-945-8676 • FAX: 303-945-2555 Stokes June 14, 1995 Page 2 The required standard absorption area (based on 40 minutes per inch) is 854 square feet. Less 40% for using "Infiltrator" units in trenches would give 427 square feet. At 18.75 square feet per unit, 23 units would be required. We understand that you intend to install 30 units. The minimum size of septic tank required is 1000 gallon, however, we recommend 1250 gallon. We recommend a distribution box be utilized to equalize the flows to the trenches. If you have any questions or need additional information, please contact us. Sincerely, HIGH COUNTRY ENGINEERING, INC. Tir othy P. Beck, P.E.

Don't: • Pour cooking grease or oil down the sink or toilet. • Rinse coffee grounds into the sink. • Pour household chemicals down the sink or flush them. Do: • Eliminate or limit the use of a garbage disposal. • Properly dispose of coffee grounds a food. • Put grease in a container to harden before discarding in the trash. Don't: • Flush non -degradable products or chemicals, such as feminine hygiene products, condoms, dental floss, diapers, cigarette butts, cat litter, paper towels, pharmaceuticals. Do: • Dispose of these items in the trash can! Don't: • Park or drive on your drainfield. The weight can damage the drain lines. • Plant trees or shrubs too close to your drainfield, roots can grow into your system and clog it. Do: • Consult a septic service professional to advise you of the proper distance for planting trees and shrubs, depending on your septic tank location. Don't • Concentrate your water use by using your dishwasher, shower, washing machine, and toilet at the same time. All that extra water can really strain your septic system. Do: • Stagger the use of water -generating appliances. This can be helpful especially if your system has not been pumped in a long time. • Become more water efficient by fixing plumbing leaks and consider installing bathroom and kitchen faucet aerators and water -efficient products.
