The table'does not, however,cover all possibilities. <br /> In such cases flow estimates are to be based on actual water_.use. Visitors to a tasting room <br /> and the periodic special events do not fit well into any category of the EH.D table. It is <br /> assumed that each tasting room customer will use the restroom two times and special events <br /> guests will use the restroom 4 times during their visits. Each restroom use will produce 2 <br /> gallons of sewage. r ' <br /> The following table summarizes estimates of maximum daily''septic sewage flow: I' <br /> Personnel Number Flow hate Total Daily Flow <br /> Full Time Employees 4 15 GPD per Person 1! 60 GPD <br /> Pari Time Em to ees* 9 8 GPD per Person 72 GPD <br /> Tasting Room Visitors** IOQ 4 GPD 400 GPD <br /> Marketing Meetings* 150 8 GPD per Person 1.200 GPD <br /> TOTAL MAX DAILY ;f - 1,732 GPD <br /> +� USE <br /> * Assumes part timers work approx.half time. <br /> ** Assumes 2 restroom visits each day at 2 gals.per use for a maximum of 100 customers. <br /> *** Assumes 4 restroom visits each day per person at 2 gals.peruse. t <br /> Using the 1,732 GPD number as the daily flow rate, the standard design criteria established-by the EHD <br /> suggests the septic tank capacity should be at least 2,425 gallons. x <br /> ' <br /> N. :;1 <br /> r. <br /> f.
