PRECIPITATION AND Eto DATA FOR STOCKTON, CA <br /> June 0.25 7.80 0.26 -- <br /> July 0.23 8.06 0.26 -- <br /> August 0.40 7.13 0.23 -- <br /> September 0.76 5.40 0.18 -- <br /> October 1.39 3.72 0.12 -- <br /> November 3.31 1.80 0.06 1.51 <br /> December 3.67 0.93 0.03 2.74 <br /> TOTALS (in.) 1 18.92 53.4 ------ 8.67 <br /> i <br /> This chart illustrates that evapotranspiration far exceeds precipitation,even when using higher rainfall <br /> data that exceeds normal rainfall data by 56%. Only in the months of January, February,November and <br /> December would deep percolation potentially occur. This data illustrates a relatively high potential for <br /> there to be significant evapotranspiration(or bare soil surface evaporation)from the wastewater disposal <br /> leachline trench design that may take advantage of evapotranspiration during the favorable summer <br /> months of any given year. <br /> III. NITRATE LOADING STUDY FINDINGS <br /> A. WASTEWATER FLOW VOLUME PROJECTIONS AND CHARACTERISTICS <br /> Wastewater Flow Volume Projections <br /> Determination of wastewater flow volume projections for this project is difficult due to the existing <br /> and proposed sources. Typically, loading projections for these types of facilities are based on the <br /> maximum anticipated wastewater flows generated by people that occur daily,yearly, or for singular <br /> events. This project has all three of these parameters. Existing sources within the boundaries of the <br /> subject Parcel include; 1) Residential structures,2.) The existing Temple structure, and 3.) The <br /> proposed Heaven Temple structure. The existing and future sources are itemized below: <br /> Residential <br /> There are 16 bedrooms in the four residential structures: <br /> 2 people/bedroom x 16 bedrooms x 69 gpd/person x 365 dpy= 805,920 gpy <br /> Existing Temple <br /> The number of plumbing fixtures within the on-site existing Temple Men's/Women's Restrooms <br /> will be used to calculate average dally flows(ADFs)based on a projected maximum fixture usage <br /> of 1 x/hr; 8 hrs/d: Men's: 5 toilets, 4 urinals; Women's: 9 toilets= 18 fixtures x 2 gals/use a.5 gals flush+ <br /> 0.5 gals hand washing>=36 gals/use x 1 use/hr=36 gals/hr x 8 hr/day=288 gals/day x 365 dpy= 105,120 <br /> gpy <br /> Page -6JJ <br /> - <br /> Chesney Consulting <br />
