Maryland Department of the Environment Announces $40 Million in Funding for Water Main Replacements in Montgomery County
The Maryland Department of the Environment has announced more than $40 million in funding to replace aging water mains across Montgomery County MD, reinforcing the state’s commitment to modernizing drinking water systems and protecting public health.
The funding will support a system-wide WSSC Water program to rehabilitate or replace deteriorating water mains and house water service connections that have reached the end of their useful life. This measure is designed to reduce water main breaks, prevent service interruptions and ensure the continued delivery of high-quality drinking water to Maryland residents.
“These systems are out of sight and out of mind until something breaks,” said Maryland Department of the Environment Secretary Serena McIlwain. “Updating aging water infrastructure is a proactive investment in the reliability and safety of the water that families in Montgomery county depend on every day. We are preventing costly breaks and service disruptions.”

Has your water bill risen suddenly? Have you noticed a puddle developing in your yard for no apparent reason? If so, you may have a leaking or broken water line. Most people don't realize that this water line – which runs from the public water main on the street to their home or building is their responsibility. This line can range from 20 feet to more than 200 feet depending on your property. Over time, unpreventable environmental conditions may cause your water line to deteriorate and/or crack.
Water line failure occurs throughout the year, however, it is most common in the winter months when lines are subject to freezing temperatures.

Montgomery County Maryland Water Line Repair And Replacement FAQs
1. Why is water collecting near my foundation when it has not rained?
Unexplained water near the foundation may come from a leaking underground water service line. Other possibilities include drainage or plumbing problems, so professional leak detection is needed to locate the source before repairs begin.
2. Can an underground water leak cause my water bill to increase?
Yes. A damaged water line may leak continuously even when no fixtures are running. A sudden increase in water usage, combined with low pressure or wet ground, can indicate a hidden water service line problem.
3. How can you locate a water line leak beneath a lawn or driveway?
Depending on the property, technicians may use acoustic leak detection, pressure testing, moisture detection and electronic line-locating equipment. Identifying the affected area helps limit unnecessary excavation around Montgomery County lawns, sidewalks and driveways.
4. When is complete water line replacement more practical than repair?
Replacement may provide a better long-term solution when the line has widespread corrosion, outdated materials, multiple leaks or a history of repeated failures. A localized repair may be appropriate when damage is confined to one section and the remaining pipe is reliable.
5. Are trenchless water line replacement options available in Montgomery County?
Some properties may qualify for trenchless installation using limited access points and specialized equipment. This approach can reduce disruption to landscaping and paved surfaces. The pipe’s route, depth, material and proximity to other utilities determine whether trenchless replacement is suitable.
6. Who is responsible for repairing a damaged water service line?
Property owners are generally responsible for the private water service line connecting their building to the public water system. However, responsibility can depend on the exact location of the leak and the utility provider’s policies. The damaged section should be located before scheduling repairs.
