Per conversations with the owner, they are proposing to construct a 4 -bedroom house. We are proposing to install a Quanics Aerocell treatment system (in a CAT II configuration) and a bed type drainfield. Because of the tight receiving soils, we are proposing to install a sand filter to minimize the potential of biomat formation at the receiving soils. Two testholes were excavated on the lot and the proposed drainfield is designed around the 30 -foot radius of both testholes. Comments regarding the design are summarized as follows: 1. SOILS: See attached 2019 testhole by Garness Engineering Group, Ltd. which shows, soil classification, percolation test and groundwater monitoring. 2. DRAINFIELD DESIGN: See attached design drawing for drainfield specifications. 3. SURFACE WATERS: There are no surface water concerns. 4. TOPOGRAPHY: There are slopes greater than 25% to the southwest of the proposed drainfield; however, the proposed system is 50'+ to those slopes. In addition, topography information was taken at the proposed bed location and the majority of the proposed drainfield area is less than 10% (see attached plot plan). However, there may be portions that exceed 10% depending on the how the bed is "laid out" during construction. It should be noted that the proposed bed has a maximum depth of 7.5 feet with only 0.5 feet of effective. In short, if there is a "grade change" over the bed, it will not negatively impact the drainfield total depth or vertical separation requirements. 5. APPLICATION RATE: Per MOA onsite code, CAT 11 treatment system with a percolation rate of 120 min/inch requires a 0.3 application rating. We are requesting that your department allow for a 0.5 application rating to be used. Justifications for granting this variance is as follows.- We ollows: We are proposing to utilize a one (1) foot minimum sand filter. This will be an additional level of treatment post-AWWfS. It is reasonable to believe that after the CAT li effluent passes through the treatment unit and then through one foot of sand, the BOD and TSS levels will be significantly less than the minimum MOA standards for CAT III (10 mg/L) and certainly non-biomat forming. It is a well known fact that the biomat depths observed in failed drainfields (even in conventional drainfields) does not extend more than 12 inches into sand filter material. In short, the proposed sand depth is thick enough to ensure protection of the underlying receiving soil. At the time the Quanics CAT 11 system approval was granted the ATS -6 trickling filter (3-4 bedroom models) only had 53 cubic feet of open -cell foam cube media and the BOD/TSS levels average less than 16/mg/L (20 samples). We are currently using the Anua/Quanics NS500 pod for 3-4 bedroom applications, which has 85 cubic feet of open -cell foam cube media. In short, the 3701 East Tudor Road, Suite 101 *Anchorage, Alaska 99507-1259 Phone: (907) 337-6179 * Fax: (907) 338-3246 * Website: www.garnessengineering.com Page 2 of 2 new NS500 model trickling filters have 60% more treatment capacity, when used on 3-4 bedroom applications, than the models used for MOA CAT II testing/approval. It is quite likely that if the new units were re -sampled, the BOD/TSS levels of the CAT II systems would meet the CAT III BOD/TSS effluent requirements. Testing data submitted to the MOA in 2005 indicated that effluent from the Quanics systems (in a CAT II configuration) had lower Fecal Coliform levels than the Advantex systems (which have been treated as CAT III systems). For this particular installation we will have 4+ feet of vertical separation to groundwater. Based upon the above bullet points, biomat formation is not a concern and virus/pathogen contamination of the aquifer is not a concern. 6. BED WIDTH: We are requesting that your department allow for a bed width of 20 feet to fit the site conditions. The non-biomat forming effluent will be discharged to a central header of the bed and then disbursed laterally through filter sand, allowing for enhanced dispersal of effluent to the receiving soil, minimizing hydraulic mounding below the drainrock. Extra care will be taken to ensure the machine does not "walk" along the bottom of the bed until the sand is placed. We will be utilizing a sand filter and an AWWTS system, which is a significant improvement to a standard bed. We are unaware of any adverse impacts this installation would have on adjacent wells or septic systems. If you have any questions, please contact us at 337-6179.
