An Award-Winning company Time and Time Again!

We provide leading Baltimore County, MD Water Treatment and Well Pump Service


Outstanding Installations & Service

National Water Service has been delivering first-class Baltimore County water service to residents for over 30 years, and we still keep our sparkling service record. Our installers are trained in both Water Treatment and Purification, as well as all other aspects of well pump service and can perform the professional installation you're looking for.

Our prices are affordable and yet we still continually find the time to invest in classroom learning for our service members, on-the-job training, and the equipment needed to provide you with the best service.

In addition, we conclude every installation with a thorough final review to ensure that the water quality is as promised and that the installation is plumbed to international plumbing codes as well as our strict guidelines!
