According to the San Joaquin County <br /> Sewage Standards, the office use rate should be 30 gallons per day. The San Joaquin County <br /> F! Sewage Standards are based on the 1963 Manual of Septic Tank Practice- The text from Crites <br /> and Tchobanoglous (1998) (Table 4-2)mentions that the typical use rate is 13 gallons per day for <br /> an office or industrial building worker. The EPA (1980)Design Manual (Table 4-6) indicates <br /> the typical use rate is 14.5 gallons per day for an office worker. <br /> Since the Crites and Tchobanoglous (1998) information is the most current available, our office <br /> ��believes it provides the best estimate of waste water flow for the office worker category. <br />
