Wastewater Treatment System <br /> , FALL.CREEK <br /> Engineering Report "r,�[ ENGINEERING,INC. <br /> receive a high level of treatment as the water flows through the planted wetland area. Microbes <br /> attached to the surface of the media and on the roots of the plants will digest and treat wastewater <br /> constituents. A schematic of the proposed system is shown in Figure 1.1. More information <br /> about the existing winery and proposed treatment system can be found in the accompanied plans <br /> and the Report of Waste Discharge prepared by Fall Creek Engineering, April 2002. <br /> The combination of the screen, septic tank, and wetland is expected decrease effluent BOD <br /> (organic matter), nitrogen and suspended solids content by 80 to 95 percent. Treated wastewater <br /> %„ will be applied at appropriate agronomic rates and loadings to a 0.6-acre landscape irrigation <br /> %W area. Most wastewater applied to the grassed area will be lost to evapotranspiration with a small <br /> amount potentially infiltrating. <br /> r. <br /> 0.6-ACRE IRRIGATION AREA <br /> _ FLOOR DRAINS C� <br /> PUMP TANK AND <br /> PUMP BASIN PUMP SYSTEM <br /> VAr WITH LOW-HEAD <br /> HIGH VOLUME <br /> `► EFFLUENT PUMP <br /> 1%r <br /> STORMWATER <br /> DETENTION AREA <br /> 0.22 <br /> SEPTIC TANK <br /> J GALLON WETLANDS <br /> SEPTIC <br /> PARABOLIC <br /> SCREEN FILTER <br /> `, Figure 1.1 Schematic of the Proposed Treatment System <br /> `. <br /> %W <br /> '1r <br /> %W <br /> *Ar <br /> %W <br /> r. <br /> NW <br /> ,%W <br /> \. <br /> `. <br /> JESSIE'S GROVE WINERY MAY 2002 <br /> 2 <br />
