Reading Response: Due at 7:00 am on Wednesday, March 19: You’re surprised as the waiter sets a pitcher of some green brew on your table at the Wolverine Brew Pub. “Is this left over from St. Patrick’s Day?” you ask your friend. You take a whiff. It smells more like algae than St. Patrick’s Day. “It’s made with real pond water,” says your friend. “Sounds delicious,” you say. “You know, I’m reading about stormwater management in Nathanson,” says your friend. “On page 263, he writes, ‘Storm sewers are usually much larger in diameter than the separate sanitary sewers serving the same area and can be placed in shallow trenches. Although they do not carry a flow during dry weather and partial flows during most rainfalls, storm sewers still must be sized to carry the peak flow from a major storm of specified intensity and duration.’ Whatever I read in Nathanson, I always try to think about how it would apply to Utah County.” “What’s special about Utah County,” you ask, “I mean, in relation to storm sewers?” “I’m guessing that our storm sewers were designed to accommodate the peak runoff from a storm that might occur every five years,” says your friend. “They probably assumed that the storm sewers would be dry during the summer. But with everybody watering their lawns all night all summer, the storm sewers must run all summer.” “Why is that a problem?” you ask. “There’s no way that excessive sprinkler water can be anything like a five-year storm.” “I don’t know,” says your friend. “I still think that there’s got to be some problem with using storm sewers to carry away all the excessive sprinkler water. What do you think?” How would you respond to your friend?
