Infiltrator Chambers: Quick 4 Standard Chamber®34"x 52"x 12'; Filter Bed 34" width + 6" spacings =40 inches. 240" _ 40" =6 Chambers wide. Filter Bid 720" 0' long) 52" long/Chamber= 13.8 Chambers minus 0.8 Chamber for center feed manif�om area= 13 Chambers long N-S x 6 Chambers wide E-W = 78 Chambers total (See Attached Photograph)! As-Builts-vfvntire-system by.installer after installation (EHD Requirement) (See Attached) Monitoring of soil/effluent interface with monitoring ports within the filter bed area''with _ ( observation tubes: 4" PVC pipe at soil/effluent interface with a 4" riser flush with the grass ��dace and a screw-type cap. (EHD Requirement) CONCLUSIONS AND RECOMMENDATIONS As the calculations indicate above,the disposal area soils should manage the anticipated effluent flows from the proposed increase in events at the Windmill Ridge Winery. However, it is unknown how long the installed system will have the capacity to manage these future flow volumes. This is the reasoning behind the above-referenced recommendation of installing two observation ports for direct observation of the soil-effluent interface. Additionally, as a safety factor, it is recommended to have on-site portable toilets for large and/or long-lasting events. Mr. Prioste has stated that there have never been any problems with the subject septic system, other than immediately after installation'there a problem with the pump alarm. Septic system problems are also a major predictive factor in the assessment of the operations of a system. It is imperative that domestic water use at the SFR and the winery reception area be kept as low as possible. All plumbing fixtures should be checked on a periodic basis (preferably monthly) for leaks. Also, ensure that the SFR have low-flow fixtures installed. It is my understanding that catered appetizers and/or dine may be served at these events, with a warming oven for food safety. It is imperative that I food and food products remaining from the scheduled events are handled as solid wastes anispose of in the garbage and not through the sinks and into the septic system. There should not be a garbage disposal in the SFR kitchen sink and all food products must also be handled as solid wastes and disposed of as such. ee-All septic systems have a lifespan, which is unpredictable due to several factors. The 100% replacement area is located directly south of the primary disposal area. It will be a simple procedure to install the replacement system in this location. There is sufficient area, equipment accessability, and no decrease in parking availability when the primary disposal area fails and the time comes to install and activate this replacement area.
