The Department of Public Works (DPW) will begin flushing all hydrants the week of Monday, April 7, 2025. The flushing will begin on hydrants at the northern city limits and continue south until all are complete. For specific questions of the process, please contact the DPW at 810-329-5277 or email info@cityofstclair.com.
At least twice a year, the St. Clair DPW performs city-wide hydrant flushing. Hydrant flushing is vital to maintaining City operations. This is because hydrant flushing ensures that the City’s water distribution system is properly functioning; it makes sure that firefighters, businesses, and residents have access to a sufficient water flow. Hydrant flushing also improves water quality when iron and other mineral deposits are flushed from the water mains.
- During hydrant flushing, residents may experience discoloration in their water and may notice reduced water pressure and flow. This is perfectly safe and normal. Residents should expect their water to completely return to its normal state by the end of the hydrant flushing week. If your water has not returned to its normal color, then, please call the DPW at (810) 329-5277 or Water Treatment Plant at (810) 329-5276. Thank you.
- Although water is safe to use and consume during hydrant flushing, you may want to collect water (in pitchers before flushing) for your everyday use, including drinking and cooking. If you use water during hydrant flushing for tasks like dishwashing, laundry, or showering, you may experience discoloration/staining of your clothes or household items. Take the initiative and get your laundry and dishes done before hydrant flushing starts.
- Water is discolored because mineral deposits are being stirred up and flushed through the system. However, there are no health hazards associated with discolored water. The water is safe to use and consume during hydrant flushing, but it may stain laundry and other household items.
- If your water is discolored, slowly run cold water out of your faucet until the water becomes clear. You may have to do this several times before your water returns to its normal state.
