The National Water Service website provides information about sustainable water resource management, regulations, and responsible usage practices. For 40 years, National Water Service has been installing and servicing complex water systems in Homes, Restaurants, Hotels, Hospitals, Shopping Centers & more all over the DC, Baltimore & Frederick Metro areas. We work with Architects, Builders & Construction Firms to create custom applications for residential & commercial water treatment, purification, as well as a complete line of well pumps, boosters, etc. Whether on City Water or a Well System, water quality can vary quite a bit from street to street and we are happy to do a basic analysis of your water and/or existing water treatment at no charge. Our installers are all professionally trained in Water Treatment, Purification, Filtration and are certified well water specialists!
