WATER FLUSHING PROGRAM
To maintain the water quality throughout the water distribution system, MVD performs flushing of the water mains as needed, typically in the spring and autumn. The program involves opening fire hydrants to create increased water flow, which dislodges and cleans out naturally occurring sediment in the water mains.
Flushing typically occurs between the hours of 8:00 AM and 3:00 PM. MVD provides notification of the streets scheduled for flushing on the Water Flushing Schedule located on the Home page's Main Menu under Calendar/Schedules. Flushing information is also posted to our Facebook page.
Please note: During the water flushing, there can be fluctuations in pressure and/or brief interruptions of water service. Additionally, flushing may cause minor flooding of streets and discolored water.
Discolored water is typically caused by sediment, such as iron. Although discolored water is not aesthetically pleasing, it is not unsafe* and can be easily resolved by flushing the water service line to the property. Flushing allows a larger-than-normal quantity of water to flow through the service line, which helps clear out the sediment. You may notice the discoloration return after the water has sat in the lines for a period of time, such as overnight or during the day if it’s not being used – this is to be expected. When the water is not used for a longer period of time, the sediment settles; when water is turned on, it is agitated and the discoloration returns. If this happens, you may repeat the flushing process.
If your water is discolored, we recommend avoiding the use of hot water until the cold water is clear. If you have used hot water before/during flushing and are noticing discoloration in the hot water, the water heater may need to be flushed – refer to the manufacturer’s manual for instructions or contact a licensed plumber.
*Some people may be more vulnerable to contaminants in drinking water than the general population. These individuals should consult with and seek advice from their health care providers.
