If the reservoir and flow control valve represent a water treatment facility and the operators want to run this facility at a constant rate 24-hours per day, what problems may occur? What change could be made to the distribution system to solve this problem? (Note- you do not need to model your solution.)

Storm Sewers and Detention

The storm drains system transports rainwater or stormwater and other runoff from roads, parking lots, and roof downpipes directly to nearby creeks, rivers, or the sea without any treatment.
