The text from Crites and Tchobanoglous (1998) (Table 4-2) indicates that the typical office <br /> worker (includes commercial workers) use rate is 13 gpd. The EPA (1980) Design Manual <br /> (Table 4-6) indicates the typical use rate is 14.5 gpd for an office worker. Since the Crites and <br /> Tchobanoglous (1998) information is the most current available, our office believes it provides <br /> the best estimate of waste water flow for both the residential and office worker categories. <br /> Therefore, 13 gpd will be used for each employee. The average waste water flow for a <br /> customer in a wine tasting room is estimated to be close or below what the average wastewater <br /> flow would be for a customer in a cocktail lounge, which is approximately three (3) gallons per <br /> person. For a customer in a banquet hall, it is estimated to be close or below what the average <br /> wastewater flow would be for a customer in a restaurant, which is approximately nine (9) <br /> gallons per person. <br /> The following table presents the septic waste water uses associated with the Site. The rates <br /> I'fl` presented from the references provide general guidance but do not always reflect a match in <br /> usage. Careful examination, professional judgment, and experience are necessary to select a <br /> reasonable flow rate estimate. The flow rates selected for the uses associated with this project <br /> are presented next. <br /> i <br /> 902 Industrial Way■Lodi,CA 95240■209.367.3701 ■Fax 209.369.4228 ©2008 Neil 0.Anderson&Associates,Inc <br />
