There are currently 420 inhabitants in the small village of Pravino. The population is estimated to increase to 940 in thirty years. The current average peak flow is 1.2 L/s and is expected to increase to 2.14 L/s by 2050. The organic load is approximately 45 g BOD5/capita/day. The community is considering a free surface wetland or a lagoon to treat their wastewater. 1. Assuming the community goes with the lagoon design. What would the BOD5 value be after the lagoon? (Make sure to justify your assumptions.)

BOD5 loading generated in the year 2050 = Organic loading * population in 2050 = 45*10-3*940 =42.3…
