2) Consider the following table. Assume that the build out population for the community is 16,000 and the residential wastewater flowrate will be 300L/capita.d. The commercial flowrate in 1999 (100m3/d) is 80% of what it will be at build-out. Due to high infiltration and inflow (II) rates, a sewer repair program will be implemented. The I/I contribution will be 200L/capita.d depending on the degree of repair achieved. Estimate the ADWF, AWWF, and the average annual flow that will be received at the community treatment plant at build-out. Justify the use of AWWF as the nominal design capacity for the treatment plant.
