Mathematical Schematic of Water Balance Calculation Variables <br /> The monthly water balance is the difference between inflows to the treatment system or disposal <br /> area and losses from the element's surface as given by the following equations: <br /> `. Wetland : SW +P +S, +RW —EW —IW —SW. = OW, <br /> �. GrassField : OW +RG, —EG, —IG = OG, , <br /> ,%. StormwaterDetention : SP_, +OG, +RP —EP —IP —SP... = OP. <br /> %W1 The following is a list of variables (all variables were calculated in gallons): <br /> %1" SW, Volume of Water in Wetland Storage RW, Direct Rainfall on Wetland <br /> .o,, SP, Volume of Water in Stormwater Detention RG, Direct Rainfall on Grass Field <br /> Storage RP, Direct Rainfall on Stormwater Detention <br /> *JW P, Process Wastewater EW, Evapotranspiration from Wetland <br /> S, Stormwater EG, Evapotranspiration from Grass <br /> EP, Evaporation from Stormwater Detention <br /> `' OW, Outflow from Wetland IW, Infiltration from Wetland <br /> `, OG, Excess water not needed by Grass Field IG, Infiltration from Grass Field <br /> OP, Overflow from Stormwater Detention IP, Infiltration from Stormwater Detention <br /> �ft. Parameters used in the water balance calculations included wetland and storm water detention <br /> `, area surface area and depth, wetland porosity, evapo-transpiration rates, grass field area, Winery <br /> area, wastewater flow rate, and soil infiltration rate. The following discussion describes the <br /> %W variables used in the above equations and the parameter assumptions. <br /> %W JESSIE'S GROVE WINERY 14 FEBRUARY 2004 <br />
