WORTHINGTON — A pipeline project decades in the making that will provide water to more than 300,000 customers in South Dakota, Iowa and Minnesota is nearing completion.

Work on the Lewis and Clark pipeline is nearing its end point in Worthington, Minnesota Public Radio reported. The pipe should be connected to the city next fall, officials said.

The city currently draws most of its water from a well field. The well’s water level can drop steeply during dry period, causing the city to implement water restrictions during times of drought.
