The new system will be sized to accommodate the maximum daily flows for a 5 bedroom residence. This OWTS consists of one sewer line from the residence. A Valley Precast 1,500 gallon, three-compartment septic tank with a 2,000 gallon total volume will be used with an Orenco PF3005 submersible effluent pump enclosed in an Orenco Biotube Pump Vault in the final compartment. The pump floats will be set to 86 gallons per dose which will be about 84 gallons due to drainback in the transport line. The soil treatment area should be sloped at 3 horizontal to 1 vertical or flatter and will consist of two 78' lateral distribution lines installed on a gravel distribution bed measuring 84' by 9' over a three foot deep sand filter basal area. The basal area of the sand filter will measure 84' by 14.5', not including the slopes of the mound. The base of the aggregate bed must be above the existing grade. Inspection ports should be present at each corner of the bed and in the center of the long sides. Gradation analysis must confirm that sand is secondary sand media. 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.

Box 5127 Edwards, Colorado 81632 jtownsend@resortconcepts.com Project No. 20-7-498.02 Permit No. OWTS-020990-2021 Subject: Certification of Onsite Wastewater Treatment System, Proposed Polner Residence, Lot 3, Block 1, Filing 36, Cordillera, 92 Pine Marten Way, Eagle County, Colorado Dear Jeff: A representative of Kumar & Associates observed the installation of the Onsite Wastewater Treatment System (OWTS) for the residence at the subject site as required by the Eagle County Environmental Health Department. Our observations and recommendations are presented in this report. The services are supplemental to Kumar & Associates agreement for professional services to WT Construction dated October 27, 2020. We previously designed the OWTS for the residence as submitted in our report dated March 23, 2021, Project No. 20-7-498.02. The system was designed for five bedrooms. The OWTS was installed by Ewing Trucking and Construction under Permit No. OWTS-020990-2021. We performed our as-built evaluations on September 19 and 23, November 30, and December 6, 2022. The OWTS components observed included: sewer line, cleanout, septic tank, effluent line, pump, control panel and soil treatment area (STA) and the locations of these components. The installation and locations of the system components were verified as shown on Figure 1. Pictures of the OWTS components made during the site visits are included with this report. The distance locations to the septic tank shown on Figure 1 were made by taping. On September 19, 2022, a sample of the secondary sand media was obtained and the results of gradation analysis test are attached. On December 6, 2022, after power had been supplied to the pump, a pump performance test was performed with adequate pump pressure observed. It is our opinion that the OWTS was installed in general conformance with the above referenced design. The observations and recommendations presented above are based on our site observations and our experience in the area. We make no warranty either express or implied. Alterations to the system or improper backfill and site grading could affect the operation and effectiveness of the OWTS.
