Question 1: What is flushing?
Answer 1: 
Question 2: How does this 
							flushing happen?
Answer 2: The high water 
							velocity is created by opening fire hydrants in the 
							street. In this way the whole water main pipe gets 
							cleaned systematically.
Question 3: What other benefits 
							does this flushing have?
Answer 3: The other benefit is 
							the testing of the fire hydrants to make sure they 
							operate properly.
Question 4: What does the 
							Hyannis Water System customer have to do?
Answer 4: If the water is 
							discolored, let the cold water run for a few minutes 
							to clear the water line. Many homes have an outside 
							spigot which generally is your first cold water tap. 
							Starting with this tap first will produce quicker 
							results to the rest of your cold water taps. 
Question 5: Is flushing a 
							health hazard?
Answer 5: 
Question 6: Should I do laundry 
							when the flushing crew is working in my area?
Answer 6: 
Customers are encouraged to 
							call the Hyannis Water System office with any
