Water… It’s What We Do!
Over 45 years ago, National Water Service began as a small, family-run business with a simple yet powerful mission—to provide clean, safe, and reliable water to homes and businesses. Founded on strong values and a commitment to excellence, our company was built from the ground up by a family that understood the importance of trust, quality service, and expert water solutions.
From the early days, we worked tirelessly to help homeowners in Maryland, Washington, D.C., and Northern Virginia overcome water challenges—whether it was fixing failing well pumps, installing advanced filtration systems, or ensuring families had access to safe drinking water. As the years passed, our expertise grew, our reputation strengthened, and our loyal customer base expanded.
