Boil Water Advisory Alert Issued for Walled Lake and Parts of Novi
Due to a loss of pressure in the cities of Walled Lake and parts of Novi, it is possible that bacterial contamination may have occurred in the water system. Bacteria are generally not harmful and are common throughout our environment. Corrective measures are currently being undertaken to correct the situation.
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 preparing food. Boiling kills bacteria and other organisms in the water. Continue using boiled or bottled water until further notice.
What happened? What is being done?
The precautionary measure is being taken due to the loss of pressure in the water distribution system. Whenever a water system loses pressure for any significant length of time, the precautionary measure of a boil water advisory is recommended.
GLWA is working closely with the communities and the team will be taking other remedial actions such as flushing and collecting bacteriological samples from around the system once the water has been restored. The samples will be collected to determine that the water quality meets all drinking water standards. We will inform you when tests show no bacteria and you no longer need to boil your water.
This boil water advisory 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.

Linear System Integrity Program
GLWA’s Linear System Integrity Program (LSIP), launched in 2021, is an ongoing program of pipeline assessment and renewal. The program is designed to proactively assess water transmission mains and wastewater interceptors and renew deteriorated pipelines to reduce the impacts of failures, improve service levels and increase reliability of GLWA’s linear assets.
The goals of the LSIP are to plan and execute condition assessments for critical pipelines; reduce impacts on Member Partners; maximize value of existing infrastructure to realize large scale return on investment and support positive social, economic and environmental impacts.
The first phase of this program occurs over the initial six years of the program, with GLWA working to assess and rehabilitate more than 100 miles of its drinking water transmission main network throughout southeast Michigan.

What’s Happening Now?
GLWA conducted condition assessment on seven miles of 36-inch transmission main on 24 Mile Road between Gaskill Ct W in Shelby Township to Romeo Plank Road in Macomb Township. Condition assessment consisted of removing the pipeline from service, draining it, and performing entry into the pipe for electromagnetic inspection, as well as visual and sounding inspection. Nine pipe segments were found to be in a state of incipient failure, requiring emergency renewal prior to returning the transmission main back in service. Renewal of the pipe segments was performed using carbon fiber reinforced polymer (CFRP). Work began early March 2024 and the emergency renewals were completed at the end of May 2024. The transmission main returned to service prior to Memorial Day.
GLWA completed the condition assessment using electromagnetics and visual and sounding inspection methods on the balance of the 4.5 miles of the 36-inch transmission main on 24 Mile Road between Romeo Plank Road and Fairchild Road mid-July. The results of the condition assessment will be reviewed and emergency repairs will be made prior to returning this portion of the pipe back to service.
