Hello my Rochester water drinking friends, just in case you missed this, be safe out there.
UPDATE #3: 5-8-26
The Boil Water Advisory that was in place for the northwest portion of Rochester Hills and southwest Oakland Township has been lifted at this time.
Recent testing confirms the public water supply is clear of bacterial contamination and fully meets all EPA Drinking Water Standards.
The Great Lakes Water Authority (GLWA) is experiencing a leak on its 42-inch water transmission main located within River Woods Park in the City of Auburn Hills. The leak caused a pressure drop in the Rochester Hills water system resulting in the Boil Water Advisory.
While the leak is under control, residents in Rochester Hills may see water pressure fluctuations during the repair process. If there is another extreme drop in pressure, another Boil Water Advisory would likely need to be issued.
GLWA is currently preparing for the repairs, but a timeline has not yet been established.
For further information, or if you have any questions or concerns, visit glwater.org or email [email protected]. We appreciate the understanding of our residents and businesses over these last two days.
UPDATE #2: 5-7-26
Residents currently under a Boil Water Advisory should know by 3pm tomorrow (May 😎 if the advisory can be lifted. The first water sample came back clean this afternoon, and we are waiting on the results from the second water sample.
Furthermore, the Great Lakes Water Authority notified us that it is investigating a break on its 42-inch water transmission main located within River Woods Park in the City of Auburn Hills.
While the leak is currently under control, if the water main breaks, residents could experience lower than normal water pressure or no water pressure. In the case of extremely low water pressure, a precautionary boil water advisory will need to be issued.
UPDATE: We have been flushing fire hydrants in the impacted area throughout the afternoon and will continue tomorrow. A first water sample has also been taken, and a second will be taken tomorrow. We expect to receive the results by Friday afternoon and will share any updates then.

A Boil Water Advisory has been issued for an area in the northwest portion of Rochester Hills and southwest Oakland Township (see map) due to a drop in water pressure levels.
At approximately 11 a.m. on Wednesday, May 6, the Great Lakes Water Authority (GLWA) was investigating a potential leak that caused water pressure levels to drop below 20 PSI. Whenever a water system loses pressure for any significant length of time, bacteria contamination may occur, and these precautionary measures are recommended. Bacteria are generally not harmful and are common throughout our environment.
What should I do?
DO NOT DRINK THE WATER WITHOUT BOILING IT FIRST. Bring all water to a boil, let it boil for one minute, and let it cool before using, or use bottled water. Boiled or bottled water should be used for drinking, making ice, brushing teeth, washing dishes, and food preparation until further notice. Boiling kills bacteria and other organisms in the water.
What is being done?
Bacteriological samples will be collected to determine that the water quality meets the state drinking water standards. We will inform you when tests show no bacteria and you no longer need to boil your water. This boil water notice shall remain in effect until results from the sampling verify the water is safe to drink. Customers will be advised when the boil water advisory has been lifted.
Please share this information with all the other people who drink this water, especially those who may not have received this notice directly.
