Hydrant Flushing


Princeton Public Utilities flushes hydrants twice per year, typically in April and October. Flushing creates a scouring velocity in the water mains in order to remove any settled material like manganese. It also serves as a fire hydrant function check and inspection. If discolored water is experienced, it is usually temporary and will clear up in a couple of hours. Running the cold water taps should help speed up this process. Contact Princeton Public Utilities if the water does not clear up so additional flushing can be scheduled.

Dedicated to the World's Most Important Resource

Drinking water is a precious resource, yet we often take it for granted.

Water is also vital to our economy. We need water for manufacturing, agriculture, energy production, and more. One-fifth of the U.S. economy would come to a stop without a reliable and clean source of water.

Systems are in place to provide you with safe drinking water. The state of Minnesota and Princeton Public Utilities work to protect drinking water sources. For example, we might work to seal an unused well to prevent contamination of the groundwater. We treat water to remove harmful contaminants. And we do extensive testing to ensure the safety of drinking water.

If we detect a problem, we take corrective action and notify the public. Water from a public water system like yours is tested more thoroughly and regulated more closely than water from any other source, including bottled water.

every drop counts

Conservation is essential, even in the land of 10,000 lakes. For example, in parts of the metropolitan area, groundwater is being used faster than it can be replaced. Some agricultural regions in Minnesota are vulnerable to drought, which can affect crop yields and municipal water supplies.

We must use our water wisely. Below are some tips to help you and your family conserve – and save money in the process.

  • Fix running toilets—they can waste hundreds of gallons of water.
  • Turn off the tap while shaving or brushing your teeth.
  • Shower instead of bathe. Bathing uses more water than showering, on average.
  • Only run full loads of laundry, and set the washing machine to the correct water level.
  • Only run the dishwasher when it’s full.
  • Use water-efficient appliances (look for the WaterSense label).
  • Use water-friendly landscaping, such as native plants.
  • When you do water your yard, water slowly, deeply, and less frequently. Water early in the morning and close to the ground.

Drinking Water Sources

Minnesota’s primary drinking water sources are groundwater and surface water. Groundwater is the water found in aquifers beneath the surface of the land. Groundwater supplies 75 percent of Minnesota’s drinking water. Surface water is the water in lakes, rivers, and streams above the surface of the land. Surface water supplies 25 percent of Minnesota’s drinking water.

Princeton has three wells that pump water from a glacial aquifer and the water is treated at one of the two water treatment facilities.

There are 3 water towers in Princeton that combine for a storage capacity of 800,000 gallons.
