Water Quality
A look into GLWA’s water quality standards, testing, and treatment practices.
96-Inch Main Relocation
The Great Lakes Water Authority (GLWA) operates 816 miles of water transmission main that serves 112 communities in SE Michigan.
A 32 mile, 96-inch water transmission main in the system running north from Oakland County to Lapeer County is the focus of this project. The project involves installing a water transmission main segment along a new route and decommissioning approximately 2.5 miles of the existing water transmission main.
The objectives of this project are to increase reliability of the 96-inch water main that serves multiple communities and over 1 million people, improve access for operation and maintenance, relocate the water main outside of businesses and backyards, coordinate with other area infrastructure projects, and to improve traffic flow and pedestrian safety by making improvements at critical intersections.
