Your wastewater treatment plant serves 1100 people, and the average flow is 80,000 gpd. What is the approximate daily flow contribution per person?

To find the approximate daily flow contribution per person, you need to divide the total flow by the number of people served. In this case, the wastewater treatment plant processes an average flow of 80,000 gallons per day (gpd) for a population of 1,100 people.

Calculating the flow per person involves taking the total daily flow (80,000 gpd) and dividing it by the population (1,100 people):

[ \text{Daily flow per person} = \frac{80,000 , \text{gpd}}{1,100 , \text{people}} \approx 72.73 , \text{gpd/person} ]

This result rounds to approximately 73 gpd per person, which indicates that on average, each individual contributes that amount of wastewater to the treatment system daily.

This value is significant because it reflects the typical range of wastewater generation per person, which is crucial for sizing and designing efficient treatment facilities. The calculations confirm that the choice identifying the daily flow contribution per person as 73 gpd/cap is the closest to the calculated figure.
