The replacement of the oldest water intake at the Evanston Water Utility continues, with work remobilizing on site on April 23 and continuing through December as lake conditions permit. The existing intake, built in 1909, is being replaced by a 60-inch diameter pipeline that extends into the lake from the water plant.
This new phase of work will mobilize heavy equipment onto the lake that will be highly visible. Equipment will be active primarily between the lakefront, an offshore mooring point approximately one mile offshore, and a construction yard in Chicago. Marine work includes underwater excavation and installation of a pipeline and intake structure in the lakebed. Marine vessels will consist of at least six barges and five support boats. Barge-based excavation will begin approximately 1000 feet offshore and proceed in two directions: toward the shore and away from the shore toward the end of the intake pipeline. Marine work will be contained within a 200-foot-wide corridor surrounded by buoys and silt curtains.
Marine work is a 24-hour, seven-day-a-week operation, as lake conditions permit. Work within 1000 feet from the shore between Memorial Day and Labor Day is permitted only Monday through Friday.
Night work is lit for safety and will be visible from the shore. All boats and watercraft must stay at least 200 feet away from all marine operations.
