The new average daily flow calculation is presented below: <br /> Average Daily Flow Calculation <br /> Use Units Rate Subtotal Adjustment Average Daily <br /> Flow <br /> Volunteers 2 13 gal/person/day 26 gpd None 26 gpd <br /> (daily) <br /> Residence 3 BR 140 gal/BR/day 420 gpd None 420 gpd <br /> Congregants, 10 10 gal/person 100 gpd 5/7, 58.7 gpd <br /> weekdays 300/365 <br /> (no kitchen use) <br /> Congregants, 40 10 gal/person 400 gpd 2/7, 93.9 gpd <br /> weekends 300/365 <br /> (no kitchen use) <br /> Congregants, 185 10 gal/person 1,850 gpd 4/365 20.3 gpd <br /> events <br /> (4 per year, some <br /> kitchen use) <br /> Retreat guests 47 50 gal/person 2,350 65/365 418.5 gpd <br /> (overnight gpd <br /> on-site) <br /> Retreat day visitors 2 10 gal/person 20 gpd 65/365 3.6 gpd <br /> Total 1,041 gpd <br /> Adjustment factors convert calculated flow into average daily flow over a year.
