The nitrate concentration of the recharge waters was estimated to be 1 mg/L-N (Hantzsche and Finnemore). Quantity and Quality of Domestic Wastewater as A two-bedroom house is located on the Site. A small, one-bedroom room "guest house" is adjacent adjacent to the house, though it is unoccupied. For the purpose of the nitrate loading calculation, three bedrooms will be considered. Crites and Tchobanoglous (1998) list a typical flow rate of 50 to 70 gallons per person per day for an individual residence. The San Joaquin County Enviromental Health Department has indicated that maximum flow and double occupancy within each bedroom should be considered for the nitrate loading assessment; as a result, a value of 140 gallons per bedroom per day has been selected (personal communication, January 6, 2017). A typical residential concentration of 35 mg/L of nitrate as N is selected (Crites and Tchobanoglous, 1998). According to Mr. Tacsion, a maximum, f 200 people will attend the facility for services once per week. The staff of the facili will be Mr. Tacsion and his wife; because they live on-site already, their contribution is xcluded from the wastewater flow calculation. In addition to the weekly services, Mr. Tacsion indicated that a youth group of up to 20 people will meet once per week, and an anniversary event will take place once per year with an attendance of up to 100 people. The On-Site Wastewater Treatment Systems Standards indicate 5 gallons per seat is the typical flow for a church with no kitchen; we understand that the facility will not include a kitchen. Crites and Tchobanoglous indicate 3 gallons per seat is the typical use for an assembly hall. Five gallons per day per seat is a commonly used factor for a religious facility and was selected for this project. The nitrate as nitrogen (N) concentration of the church facility wastewater is estimated to be 85-mg/L (Crites and Tchobanoglous, 1998). The estimated flow values discussed here should not be used for the design and sizing of the septic system. The design and sizing of the septic system should utilize the San Joaquin County Environmental Health Department's On-Site Wastewater Treatment Systems Standards which incorporate peak and surge flow factors. The estimates used in the On-Site Wastewater Treatment Systems Standards may be greater than those discussed here. The maximum average daily flow for the Site was estimated to be 578.6 gallons per day (gpd). Through the use of a weighted average, the average concentration of all the different effluent flows and concentrations was determined to be 48.7 mg/L-N at 578.6 gallons per day. Please see the following tables that present the information in a tabular form. LOGE 1917 Page 11
