Question 8 The table below presents the average monthly flows received by a municipal wastewater treatment plant servicing a small residential community for the period from 2007 - 2010. (a) Determine the average annual flow, average dry-weather flow (ADWF), and average wet-weather flow for each year. Assume the dry season occurs from June to October (inclusive), and the wet season occurs from November to May (inclusive). (b) Determine the per capita flow contribution from commercial and light industry for each year assuming the residential contribution to the dry weather flow is approximately 270L /capita.d. (c) Determine the per capita contribution from infiltration and storm water inflow for each year assuming the difference between the wet and dry weather flows is due to infiltration and stormwater inflow
