[ARCHIVED] Water Hydrant Flushing Beginning March 20, 2019

Water Hydrant Flushing

Beginning March 20, 2019

The Twp. Hydrant Flushing will begin weekdays starting MARCH 20th between the hours of 9AM-3PM. The purpose is to remove accumulated sediment in water mains and comply with NJ DEP regulations that require all Township hydrants be inspected and flushed.

Discolored or cloudy water is potable, but not desirable for use. We strongly recommend that customers refrain from doing laundry & using water for drinking and cooking from 9am to 5pm.

We have divided the Township into 4 areas which were determined by which water tank feeds the area. Please refer to the Hydrant Flushing Area Map or the Street List to determine which area you are in. The areas will be flushed in the following order: red, yellow, blue then green. Please monitor the Street List to follow our progress. The rate of progress is directly affected by the flushing conditions found as our team moves through the Township. 

Please keep in mind that discolored water could occur at any time during the flushing period but more likely when we flush the water mains in your neighborhood. The Street List will be updated to show streets that have been flushed.


This process could result in discolored/cloudy water or low pressure during & immediately following the daily flushing. If you experience discolored water, wait until the crew is away from your immediate area or until the flushing period is over for the day, open the cold-water faucets on the lowest floor of the house & allow the water to run until it clears (usually within 30 min).

For water emergencies between the hours of 8:30 am to 4:30pm, contact the Water & Sewer Dept. at 973-331-3330. After hours please contact the Montville Police Dept.

Please check the Hydrant Flushing page at for links to the maps, streets and updates when applicable daily.
