Kallenbach, PE. The system is designed to serve a maximum daily flow for the proposed seven bedroom single family residence. The OWTS consists of a 1,530 gallon tank followed by a 500 gallon tank, both Infiltrator poly septic tanks, installed for primary treatment and with an effluent filter on the outlet tee of the second tank. The primary tanks are followed in series by an Eliminite 120 Treatment System and a 500 gallon dose tank, equipped with a recirculation pump and transfer floats set to circulated effluent back to the primary treatment tank. The dosing tank is also equipped with a Liberty LEH150 high head pump with floats set as shown in the design to pressure dose effluent over a 2,100 square ft soil treatment area consisting of seven shallow one foot deep trenches, each 100' in length and equipped with chambers. Be sure to stake and maintain all setback features, including the proposed location of the water line. Distribution lateral details, along with orifice size, spacing and orientation are on the design drawing. The contractor must verify that all electrical components and inspections are covered under the electrical permit associated with the control panel and pump connections. The alarm must be connected to a separate circuit. Additional pump details are on the design drawing. Please note that a soil profile test pit is required prior to installation of the OWTS, that is immediately adjacent to and down gradient from the proposed soil treatment area, to confirm adequate vertical separation from limiting layers such as fractured bedrock observed in nearby soil test pits. 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 or occupancy of the dwelling.

This is my professional opinion, both as the project engineer for more than two decades, and as the manufacturer of Eliminite advanced treatment systems. I have conservatively—and, in a technical sense, unnecessarily--increased the sizes of the primary tanks and drainfield to comport with the default sizing criteria within the regulations. However, the sizing criteria presented in the current regulations diverge so far from actual residential flow data, blind implementation of that criteria would not be considered competent engineering practice in any other arena. However, I recognize the necessity of conforming to the regulation as closely as practical, without compromising reliable treatment performance, which I have done in these designs. Our study of 600+ homes in Eagle County prior to Red Sky Ranch’s state and local approvals, combined with twenty years of experience dealing with treatment systems for Red Sky Ranch has unequivocally established the actual daily wastewater production is significantly lower than the assumptions presented in the regulations. Previous regulations in place when this project was first proposed required design flows of 225 gal/bedroom/day. This value resulted in a requirement for absurdly large system components and was the driving force behind our comprehensive study. The result of the study was that a design daily flow of 325 gallons was appropriate for Red Sky. These findings were reviewed by Eagle County Environmental Health and CDPHE, presented at public hearings, and were approved by both entities. Although you mentioned Eagle County lost all files related to Red Sky Ranch during a recent office move, I’m certain there are still digital records of public hearings where findings were discussed and approvals were granted (perhaps even through a basic google search); additionally, the project itself provides ample evidence of such approvals, in the form of all currently constructed, operational infrastructure installed to date in compliance with prior state and local approvals. Current water data corroborates the results of the original study and in fact, possibly due to more widespread use of water conservation devices, establishes an even lower value than the 325 GPD that was approved by CDPHE and Eagle County at the project’s inception. Red Sky Ranch homes average between about 80 and 130 GPD and, as you are probably aware, is in good agreement with current research showing almost no correlation between number of bedrooms and daily wastewater flow. Further, best engineering practice demands prioritization of actual site specific data over hypothetical default values. From a treatment perspective, particularly where biological processes are optimized as they are in an Eliminite system or any recirculating biofilter-type technology, wastewater stagnating in tanks for extended periods of time is not a desirable situation. Particularly in a cold, high-altitude climate, the heat loss from excessively oversized tanks results in significantly reduced kinetic parameters and may negatively impact treatment efficiency. In my submittals to you, I have done my best to strike an acceptable balance between satisfying hypothetical default values imposed by an ever- evolving regulatory scheme in Colorado, and providing my clients with an appropriately-sized, conservatively designed system that will actually provide long-term reliable treatment and safeguard the surrounding environment as Red Sky’s systems have done so far. In summary, the systems at Red Sky have been designed to function both mechanically and biologically. The robustness of the designs have been proven over 20 years of operation; I have specified precisely the system designs I believe will work best for these homes. If, however, you determine that imposition of the new default table values should override my judgment as a Professional Engineer, I will accept your recommendation and will amend my design to conform to your preferred design. Please do not hesitate to contact me with any questions or concerns you may have. If you do decide to require an amended design, please provide a detailed description of the basis for the change and details regarding your preferred design. Sincerely, Thomas J. Kallenbach, P.E.

Attn: Tom Kallenbach, PE WQCP LLC conducted the tests and verifications that were requested for the design engineer to sign off on the system. Watertight test: Primary tank test - The test started at 15:00 on 6/17/2023. The static water level was 26.75” below tank riser lid. The test was complete on 6/19/2023 at 08:00. The static level remained at 26.75” below the tank lids for the duration of the test indicating the tank is watertight. 500 gallon tank test. The test started at 16:00 on 6/17/2023. The static water level was 27.25” below tank riser lid. The test was complete on 6/19/2023 at 08:00. The static level remained at 27.25” below the tank lids for the duration of the test indicating the tank is watertight. Drain field test: Squirt test was performed on 6/20/2023. Eagle County Environmental was onsite to witness the test. Before the squirt test was conducted the drain field laterals were flushed to remove and debris that may have entered the pipes during construction. Installation: The Eliminate system was constructed per the drawings received from Tom Kallenbach PE. The primary, Eliminite and dose tanks were installed per the drawing. Pump check: Float system was tested and working properly. The HWL float switches and Eliminite fail alarm were tested and functioning properly. Eliminite pump 6.8 Amps. Transfer pump 7.1 amps.
