Using statistical analysis, assess the variability of the following wastewater monthly inflow data (Flow, TSS, COD, COD Load, TSS Load) and discuss the following: 1. Impact of input data variability on design? 2. Which input values would you use in your design and why? 3. Given your chosen design values, how certain are you that your input variables will not be exceeded? 4. Discuss the impact of your choice of design input data on project cost?
