Visitations will extend daily to 8 pm. On Saturday and <br />Sunday, the facility will be staffed with up to 8 employees. <br />The total maximum daily septic tank usage for the proposed Vineyard Chapel addition was <br />calculated using the maximum number of employees (25) and maximum number visitors (100) <br />expected per day. Effluent was based on the EHD recommended daily use rate of 13 gallons per <br />day (gpd) per employee and 2 gallons per day per visitor (Refer to Section 1.1). <br />25 employees x 13 gpd + 100 visitors x 2 gpd = 525 gpd <br />The septic system design should be based on the San Joaquin County On-Site Wastewater <br />Disposal Standards or other engineering recommendations. Refer to Terracon’s Engineered <br />Septic System Report (Project No. NA207102) for septic system design parameters for the <br />Vineyard Chapel addition. <br />Facility - Below is a table of the overall septic system usage calculated for the facility.
