City of Flint August 25, 2021 update: secondary water pipeline


The secondary water pipeline valve has been fixed, calibrated and is now in operation to start the 95-5 water increments to the secondary water pipeline.

FLINT, Michigan— Officials from the City of Flint Department of Public Works have not started the 95-5 water increments to the secondary water pipeline as planned due to minor valve work and calibration needed on the secondary water pipeline to allow for automated operation. After confirming these adjustments have been completed and the instrumentation is properly calibrated, the City will move forward to operate the secondary water pipeline as planned. Updates regarding this project will continue.

All protocols with the State of Michigan Safe Drinking Water Act and the City’s agreement with its primary water supplier, the Great Lakes Water Authority (GLWA) will continue to be followed. Residents will continue to be updated regarding the progress of this infrastructure project.
