v <br /> jr December 1, 2004 <br /> NOA Project Number. E040117A <br /> r nces provide general guidance but do not always reflect amatch t a <br /> usage. Careful examination,profession <br /> in <br /> presented from the refereal judgement, and experience are necessary m <br /> reasonable flow rate estimate. The flow rates selected for the uses associated with this project <br /> are presented in the following table. <br /> Table 1. <br /> Typical Quantity of Effluent for Parcel 1 from Various Sources. <br /> Category Total People per Average Quantity per Average Daily Flow <br /> Day Person Per Parcel <br /> Residential 4 70 gal/day/person 4 residents/day• 70 gpd/person <br /> =280 gpd "7,3 <br /> Mini-Man 4 13 gal/day/person 4 workers/day• 13 gpd/person ­' f` <br /> (workers) =52 gpd <br /> Mini-Man 10 5 gal/day/person 10 customers/day' 5 gpd/person <br /> (Customers) =50 gpd <br /> Note —gpd is gallons per day. <br /> Table 2. <br /> T i-al Want' of Effluent for Parcel 2 from Various Sources. <br /> FrRe! <br /> ry Total People per Average Quantity per Average Daily Flow <br /> Day Person Per Parcel <br /> ial 7 70 gal/day/person 7. 8 residents/day ' 70 gpd/person <br /> =490 glad <br /> Note —gpd is gallons per day. <br /> For Parcel 1, the total daily waste water quantity is 382 gallons per day. The daily waste water <br /> quantity for parcel 2 is estimated to be 490 gallons per day. <br /> The average total nitrogen concentration of domestic waste water is normally considered to be <br /> 20-85 mglt, N (Crites and Tchobanoglous, 1998). For the purposes of the nitrate loading <br /> estimate;the long-term average concentration for total nitrogen in waste water is estimated to be <br /> 45 mg/L-N. <br /> 5 <br />
