Know about water main breaks


A water main break happens when an underground pipe carrying drinking water to homes or businesses cracks, splits, or bursts. Water escapes under pressure into the ground instead of continuing through the system.

What happens during a water main break


  • Sudden loss of water pressure or no water at all
  • Water pooling in streets or yards
  • Possible discolored (brownish) water
  • Temporary road closures
  • Crews excavating and repairing the pipe

Water utilities isolate the damaged section by closing valves, repair or replace the pipe, then flush and disinfect the line before restoring service.

What to do after a water main break


Step 1: Flush Your Plumbing. Turn on a cold-water faucet (like your kitchen sink) and let it run for 15–20 minutes, or until the water runs clear. Then run the cold water at other faucets and fixtures throughout your home for a few minutes each.

Step 2: Clean Your Appliances. After flushing your home’s water lines, run your dishwasher and washing machine empty on a hot water cycle to clean and sanitize them before regular use.

Why water main breaks happen (especially in Northeastern Pennsylvania)

In Northeastern Pennsylvania (NE PA)—including areas like the Lehigh Valley—there are several common causes:

Freeze–thaw cycles
NE PA has cold winters. When the ground freezes, it expands and puts pressure on buried pipes. When it thaws, the ground shifts again. Repeated expansion and contraction stresses older pipes and can cause them to crack.

Aging infrastructure
Many water systems in the region were installed 50–100+ years ago. Older materials like cast iron become brittle over time and are prone to breaking.

 

Ground movement and soil conditions Parts of NE PA have:

  • Rocky soils
  • Clay that expands and contracts
  • Areas affected by historic mining

These conditions can shift or settle unevenly, putting stress on underground mains.

Traffic vibration

Heavily traveled roads create constant vibration and weakens older pipes over time.

Pressure changes

Sudden pressure spikes in the system (like from hydrant use during firefighting or valve operations) can cause weak sections of a pipe to fail.

Corrosion

Soil chemistry can slowly corrode pipes from the outside, especially older metal mains.

 

What to do for a Boil Water Notice


Boil all water used for:

  • Drinking
  • Cooking and food preparation
  • Brushing teeth
  • Making ice

Bring water to a rolling boil for at least one (1) minute, then let it cool before use.

Bottled water may be used as an alternative.

How will I know if I should Boil Water
Easton Suburban Water Authority would notify customers via phone call, email, text message, letter, or a door hanger if a boil water advisory is required.
