7�=eHleaven sed Heaven Temple Temple Restrooms are proposed to be used extensively only 3x/yr during the Buddhist New Year, which is a consecutive three day event. Use of the Restrooms throughout the remaining days of the year may only amount to 10%of this maximum three-day usage according to the Father Monk. The number of plumbing fixtures within the on-site existing Temple Men's/Women's Restrooms will be used to calculate average daily flows (ADFs) based on an assumed maximum fixture usage of 3x/hr; 8 hrs/d, 3 dpy: Men's: 9 toilets, 7 urinals; Women's: 16 toilets=32 fixtures x 2 gals/use (1.5 galsflush+ 0.5 gals hand washing)= 64 gals/use x 3 uses/hr= 192 gals/hr x 8 hr/day= 1,536 gals/day x 3 days of each year=4,608 gals. Ten percent usage the remaining days of the year: 1,536 x 10%= 154 gpd x 362 dpy= 56,064 gals. This yearly flow volume figure totals: 805,920 (residential); 105,120 (existing Temple) and(4,608 + 56,064 -proposed Heaven Temple)=971,712 gpy. This figure will be used for the yearly wastewater generation of the entire facility for the nitrate loading calculations below. Wastewater Characteristics To accurately quantify nitrogen concentrations to calculate nitrate loading, a septic tank effluent sample was taken from the second compartment of the second tank that serves the existing Temple before the effluent flows to the disposal area. The Table below reveals the TKN to be 89.6 mg/L. The nitrate concentration was reported at<2.5 mg/L, however, according to Denele Labs,this is equivalent to non-detect(ND) and due to reporting purposes,this figure must be used. This concentration of 90 mg/L of TN will be used in the loading calculations below. The scientific literature cites nitrogen concentrations in domestic septic effluent at a value of 62 mg N/L(See Kaplan-Septic Systems Handbook,Pg. 147). Consequently, this is a 45% increase in nitrogen concentration used in the calculations.
