<br /> Illow All of the water balance and surface loading rate calculations described in Section 4.3 were
<br /> performed again to analyze the system under the projected 10-year flows (as described in
<br /> Sections 3.1.2 and 3.1.3). Nothing changed in the calculations except the flow rates of both the
<br /> process water and the storm water. FCE performed this second set of water balance and surface
<br /> loading rate calculations to assess the performance of the wetland treatment system under future
<br /> flow conditions.
<br /> 5.1 Water Balance Calculations
<br /> Monthly water balance calculations were performed for the wetland, grass disposal area, and
<br /> storm water detention area at Jessie's Grove Winery under the projected 10-Year plan flows.
<br /> .. The monthly water balance is the difference between inflows to the disposal area and losses from
<br /> the element's surface. Parameters used in the water balance calculations included wetland and
<br /> storm water detention area surface area and depth, wetland porosity, evapo-transpiration rates,
<br /> grass field area, Winery area, wastewater flow rate, and soil infiltration rate.
<br /> ..
<br /> Average and wet annual rainfall years were modeled to assess the capacity of the proposed
<br /> wetland/land disposal system to manage wastewater and storm water discharged from the
<br /> winery.
<br /> L Water Balance Calculation for Average Annual Rainfall
<br /> The estimated flow rates for the 10-year plan is approximately 0.5 million gallons of process
<br /> water is generated per year. Table 5.1 presents the results of the water balance calculations
<br /> �- based on this process water estimate and the storm water flow in an average rainfall year(0.5
<br /> %W million gallons). The water balance calculations show that during average rainfall years, the
<br /> fields perform hydraulically without any overflow.
