What is a Water Main Break and Am I Responsible?

large green water main pipes

If you own a business or residence that is on city supplied water, you have a water main, this is the underground pipe that delivers water to your service pipe. In residential areas it usually runs underneath the street and sidewalk. If the water main breaks, you will probably still have water, unless it is shut off while the break is being repaired. Because the water in the main is under pressure, the water will find its way to the surface, this could be in your home or outside on your property.

What Causes a Water Main Break?

Water main breaks are usually caused by external corrosion on the pipes. Some soil is highly conductive and can easily corrode metal pipes from the outside in, changing soil condition, like freezing, can cause a weak pipe to break.

Who is Responsible for Water Main Break Repairs in Maryland?

The water main is generally maintained by the city or the county that you reside in. If there is a break the city or county should be called to assess the damages and make repairs first. There is a portion of the main between the sidewalk and the house or business that is the responsibility of the property owner.
