PWSD performs seasonal, and incident based, system maintenance which includes water main flushing to reduce the frequency of discolored water in our water mains.  


A significant portion of our drinking water is made up of well water that is located hundreds, and in some cases thousands of feet below the surface of the ground.  This water has naturally occurring minerals that can settle in the water mains.  Rapid changes in water use can stir up these minerals, causing discolored water.  This typically occurs in the spring and fall when there are changes in seasonal water demands.  While discolored water may look alarming, it is safe. 


Although discolored water is completely safe, we understand that it is an inconvenience and looks alarming.  PWSD is addressing removing the naturally occurring minerals from well water that causes of discolored water, including putting filters in well houses to reduce the minerals in the water before it gets into the distribution system.  We are also hard at work implementing operational procedures that reduce the amount of discolored water that stays in water mains that can eventually end up in your home or business.  This includes seasonal flushing when water demand fluctuates.  We are also implementing proactive notifications so that you know when crews are flushing hydrants in your area. 

  • Visit our website at to view maps and timing of when and where crews will be flushing in your area, or click on
  • Listen for automated calls from us letting you know when crews will be working in your area.
  • Watch for social media posts on our website at or on Facebook, Instagram, Twitter, and especially on NextDoor to stay informed as to when crews will be flushing in your neighborhood.
  • Look for signs in your neighborhood notifying you of flushing operations.
  • During this time, reduce the amount of discolored water you pull into your plumbing system.  Don’t use large volumes of water in your home, and try not to use hot water.  If you have discolored water when you turn on your faucet or flush a toilet, there are steps you can take to minimize the impact of discolored water.  


While we are working hard to proactively address the issue, there are times when customers may experience discolored water.  If you do, here are some steps to take to minimize the impact. 

Step 1 – Reduce the amount of discolored water you pull into your plumbing system.

If you know crews are working in your neighborhood, try not to use large amounts of water that will draw discolored water into your plumbing system.  If you already are experiencing discolored water at your faucet or in your toilets, the following actions can reduce the impact.

Step 2 – Avoid doing laundry and don’t use hot water.

Using hot water pulls discolored water into your water heater.  The minerals can settle out in your hot water tank, and then cause problems even after the discolored incident has passed. 

If you did happen to wash laundry and notice discoloration, don’t put laundry through the dryer.  Instead call us, and we can deliver an iron stain removal powder that you can use in your washer to remove the discoloration. 

Step 3 – Reach out to us as soon as you or your neighbors notice discolored water.

We are working hard to respond to discolored water incidents as quickly and efficiently as possible.  The sooner we know of a potential incident, the faster we can respond in order to reduce the impact in your neighborhood.  If you or your neighbors are experiencing discolored water in your homes, let us know as soon as possible.  And encourage your neighbors to do the same. 

Step 4 - Once discolored water is drawn into your home, and you notice it in your faucets or toilets, the best thing to do is use cold water to pull it out of your plumbing system. 

Opening an outside hose bib helps pull the water out of your pipes, and can benefit your lawn at the same time.  Avoid using your irrigation system, as the increased minerals may settle out in or clogs drip emitters. 

Flushing your own plumbing system might feel like a lot of water, when in fact it is only around 100-200 gallons.  Try to use it on plants or on your lawn so it doesn’t go to waste.

Step 5 – Remember the water is safe.

While you may not want to bath, or do laundry, discolored water is safe.  It is an inconvenience, however, and we don’t want our customers to have discolored water problems.  If you experience discolored water, please notify us as soon as possible, so crews can come to your neighborhood and clear the main water lines. 

Step 6 – If discolored water persists, please let us know.  Give us a call at (303)841-4627.
