In this report, we refer to the San Joaquin County Onsite Wastewater Disposal Standa-ds dated January 2017 (County Disposal Standards). II. Average Daily Flow (ADF) The Average Daily Flow was calculated as follows: DEC 0 2 2020 Assumptions: 1. 8 hours per shift ENVIRONMENTAL HEALTH 2. 3 shifts per day (300 first shift, 300 second shift, 100 third shift) PERNUT/SERVICES 3. 1 restroom use every 3 hours per employee, 2.67 uses per shift per employee 4. 2 gallons per use for 60% of the uses as toilets and 1.25 gallons per use for 40% of the uses as urinals Assume 60% of uses are toilet uses and 40% of uses are urinal uses yielding 2.67 uses per shift per employee *0.6 * 2.0 gal per toilet use = 3.204 gal per shift per employee (3.204 gpd) 2.67 uses per shift per employee *0.4* 1.75 gal per urinal use = 1.869 gal per shift per employee (2.33 gpd) 3.204 gal per shift per employee + 1.869 gal per shift per employee = 5 073 gal per shift per employee (5.073 gpd) Where: Toilet Use= Toilet and sink are considered one fixture at 2 gal/use Urinal Use= Low flow urinal and sink are considered one fixture at 1.75 gal/use Daily Use Rate = Gallons of wastewater per day generated per employee Stockton San Jose Sacramento Modesto 3428 Brookside Rd., 111 N.
