water from a waste water treatment plant is released into a receiving pond that has a volume of 5 ac-ft. one of the reasons for doing this is to assure that the chlorine residual is below 0.1mg/L before the water is released to a stream as required by the regulations. the flow rate of the WWTP is 3 MGD and the regulation is always complied with. The plant wants to replace the pond with a canal and asks you to design this. What are the dimensions?
