The nitrate concentration of rainfall was estimated to be 1 mg/L-N (Hantzsche and <br /> Finnemore, 1992). <br /> Quantity and Quality of Domestic Wastewater <br /> According to Anant Mishra,-the oposed prayer hall will be open every day for drop-in <br /> visitors; he anticipates three to visitors per day. Services will be held each Tuesday <br /> and will be attended by up eopl . Four times a year, events will be held on the <br /> Site which will be attended b peop the food for these events will be catered. <br /> --------------- <br /> The estimated sewage flow rates for various uses are available from a number of <br /> references. The uses presented below were guided by the San Joaquin County On-Site <br /> Wastewater Disposal Standards (2003), Crites and Tchobanoglous (1998), and EPA <br /> (1980). The Wastewater Disposal Standards indicate 5 gallons per seat is the typical <br /> flow for a church with no kitchen; we understand that the prayer hall will not include a <br /> kitchen. Crites anoglous indicate 3 gallons per seat is the typical use for an <br /> assembly hall(Five gallon per day per seat is a commonly used factor for a religious <br /> facility and was elects for this- _ ' ct. The nitrate as nitrogen (N) concentration of <br /> these uses is estimated to a 85-m / rites and Tchobanoglous, 1998). <br /> Mr. Mishra indicated that two houses are located on the Site, a two-bedroom house <br /> close to Eight Mile Road (Residence 1) and a three-bedroom house to the north <br /> (Residence 2). Residence 2 is to be used only when a visiting priest is present. <br /> Although Residence 2 is only being used occasionally, it is considered here as if fully <br /> occupied because its uses could change in the future. We estimate a maximum use of <br /> 2 to per day per bedroom for residential use. A typical residential concentration <br /> mg of nitrate as N is selected (Crites and Tchobanoglous, 1998). <br /> The estimated flow values discussed here should not be used for the design and sizing <br /> of the septic system. The design and sizing of the septic system should utilize the San <br /> Joaquin County Environmental Health Department's On-Site Wastewater Disposal <br /> Standards which incorporate peak and surge flow factors. The estimates used in the <br /> On-Site Wastewater Disposal Standards may be greater than those discussed here. <br /> LOGE 1325 Paae 11 <br />
