Water Main Replacement Program

February 22, 2023

Baltimore City must replace its failing infrastructure, which includes water mains that are over 100 years old.

The city of Baltimore’s Department of Public Works (DPW) oversees the Municipal water distribution system. DPW supplies drinking water to 1.8 million people in the Baltimore Metropolitan area which encompasses 3,800 miles of water mains, 67,500 valves and 23,000 fire hydrants. DPW is responsible for maintaining the 1500 miles of mains located within city limits. A program to replace or rehabilitate many of the City’s aging water mains is presently underway and may be coming soon to your neighborhood.


Project Purpose:

  • Improve water flows and water quality
  • Reduce water service disruptions and costly repairs
  • Minimize water main breaks
  • Minimize street closures


Project Activities:

  • Provide temporary water service during construction
  • Replace or repair about 2.3 miles of existing water mains
