The system is designed to serve the daily flows from a 1-bedroom residence. A minimum one bedrooms (instead of two) was approved by Eagle County staff in accordance with OWTS regulations for repair sizing due to site and size restrictions. The OWTS consists of an existing Norwesco 1,000 gallon two-compartment plastic septic tank followed by a new Infiltrator IM-540 one compartment dosing tank with an Orenco High Head effluent pump (PF500511) capable of delivering 13.8gpm against 10.9 feet of total dynamic head with floats set to dose approximately 90 gallons of effluent 41 feet to the soil treatment area (STA). The STA consists of one bed with three rows of 7 Infiltrator Quick4 Plus standard chambers for a total of 21 chambers. The bed media will be over-excavated to 4 feet, mix, large cobbles and boulders removed, and replaced before setting chambers. Be sure to stake and maintain setback distances to the water cistern, dry gulch, and utility easement. Contact Eagle County Environmental Health and the design engineer well in advance of requesting inspections prior to backfilling any component of the OWTS. The design engineer is responsible for conducting all inspections necessary to certify the installation and assure the functionality of the system. System certification, along with photos and a record drawing is required to be submitted to and approved by Eagle County Environmental Health prior to the use of the system.

The purpose of our site visit was to inspect the installation of the septic system. The system was installed in overall compliance with the septic system design, Drawing No. 22- 3627OWTS.dwg, dated July 24, 2022. At the time of the inspection, we observed the following: They installed an IM-540 Infiltrator Poly Tank - with an Orenco PF500511 high-head pump assembly, in line with the existing Norwesco, 1000-gallons, two compartments, plastic septic tank. In the second access port of the existing septic tank, new effluent filter was installed with the handle extended close to the top of the riser. The pump tank access port had 42-inch, corrugated, plastic riser with secured, green, plastic covers. The existing septic tank had 30-inch, black plastic covers, also secured with nuts, bolts and screws. The control panel was installed on the west side of the cabin, at the SW corner. The effluent line from the pump chamber to end manifold of the soil treatment area, was about 42-feet long, 1.5-inch diameter, sch40 pvc pipe. The end manifold was about 6-feet long, 1.5-inch sch40 pvc. The soil treatment area consisted of infiltrator chambers arranged in a bed configuration with three rows of 7 Quick Four Plus Standard Infiltrator Chambers in each. Four feet of the onsite material was excavated, mixed and backfilled into the excavated bed. Pressure dosing system consisting of 28-ft, 1.25-inch sch40 laterals perforated at the top with 1/8-inch holes at 4-ft intervals, suspended from the side of each row of infiltrator chambers. The ends of the laterals were equipped with flushing assemblies. A squirt test was performed during the inspection, and it was satisfactory. Claire from the ECEH Department was present during the inspection and the squirt test. All inspection ports were installed (in the end caps of the first and last chamber of each row of infiltrators) in the openings opposite the pressure distribution lines. The system installation and the startup of the pump system were done by the installer, Travor Dunsdon, Alpha Excavation, LLC. There is no other warranty either expressed or implied.

The proposed system a replacement system for a one-bedroom cabin. The failed septic tank has already been replaced with a Norwesco, 1000-gallons, two compartments, plastic septic tank. The Soil Treatment Area (STA) will consist of a bed with three rows with 7 Quick 4 Plus, Standard Infiltrator Chambers in each, for a total of 21 infiltrator chambers, over 4 feet of overexcavated soi. The soil below the infiltrator chambers will be improved by excavating four feet of the existing soil, mixing and placing it back in the excavation, per the requirements of the OWTS #43 regulations. The effluent will be applied with pressure dosing with an Orenco Pump. ! Preliminary Investigation G Address: 1924 Sweetwater Road, Eagle County, Colorado G Legal Description: Lot 2, Sweetwater Ranches, Eagle County, Colorado. G Existing Structures: There are is an existing on- bedroom, concrete block cabin. G Location of existing and proposed wells on property: There is a cistern on the west side of the cabin, as shown on the design drawing. The cistern is filled from a well on the south side of Sweetwater Road. G ECEHD (Eagle County Environmental Health Department) records: There are no records of existing septic system on the property. G Topography: The topography of the leachfield site has slope of about 10 percent. G Soil Data: The profile holes had been excavated prior to our site visit. The soil exposed in the profile holes was as follows: Page 2 of 3 P.O.
