Raw Water Supply

Raw water for the system is obtained from Lake Michigan. Water is drawn from an inlet structure 3,000 feet offshore and is directed to a raw water pump station through a 54-inch diameter steel intake pipe. A treatment to discourage zebra mussel attachment is introduced at the inlet structure and removal of algae and large debris is screened from the water at the pump station.

Raw water pumps lift the water 110 feet and convey the raw water approximately two miles through a 48-inch pipeline to the water treatment facility.
