Careful examination, professional judgement, and experience are necessary to <br /> select a reasonable flow rate estimate. The flow rates selected for the potential uses associated <br /> with this Site are presented in the following table. <br /> Table 3. <br /> Typical Quantity of Effluent from Various Sources. <br /> Scenario 1: Many Full-Time Employees <br /> Category Total People Average Quantity Average Daily Flow <br /> per Day per Person <br /> Residents 7 70 gal/day/person 7 residents/day*70 gpd/person <br /> = 490 gpd <br /> Full-time Employees 500 13 gal/day/person 500 employees/day-113 <br /> gal/day/person-15/7 = 4,643 gpd <br /> Visiting Truck Drivers 350 5 gal/visit/person 350 drivers-15 gal/visit/person*5/7 = <br /> 1,250 gpd <br /> Average daily flow: 6,383 gpd <br /> Scenario 2: Many Visiting Truck Drivers <br /> Category Total People Average Quantity Average Daily Flow <br /> per Day per Person <br /> Residents 7 70 gal/day/person 7 residents/day*70 gpd/person <br /> = 490 gpd <br /> Full-time Employees 50 13 gal/day/person 50 employees/day-'13 <br /> gal/day/person*5/7 = 464 gpd <br /> Visiting Truck Drivers 1,500 5 gal/visit/person 1,500 drivers'15 gal/visit/person*5/7 = <br /> 5,357 gpd <br /> Average daily flow: 6,311 <br /> Notes —gpd is gallons per day;5/7 is a conversion for the five-day work week,assigned in this example for <br /> estimation purposes only. <br /> As shown in the table, the maximum average daily waste water quantity of 6,600 gpd allows a <br /> great flexibility of uses on the Site. Waste water quality is discussed within the nitrate loading <br /> section of the report. <br /> 6 <br />
