Water Main Replacement, Relocation and Installation

It takes a lot of work to keep the water flowing

They're out of sight and out of mind - but if something goes wrong with a water main, you'll know.

Water mains are the big pipes that carry water to your neighborhood and home. And they have two major enemies: time and age. So WSSC Water must work continuously to replace old, worn-out mains. With more than 5,900 miles of water mains in Montgomery and Prince George's counties, it's a never-ending job.

With an eye toward fighting the effects of time and age, WSSC Water now replaces old water mains with special pipe: zinc-coated ductile iron pipe. The zinc coating helps to fight corrosion, and that gives the pipes an expected lifespan of at least 100 years - much longer than the traditional 50-to-75-year lifespan of traditional iron pipe.

Eventually, a water main project will come to your neighborhood, if it hasn't already. When it's time, WSSC Water will give you plenty of advance notice.
