At National Water Service, we understand that businesses, institutions, and industrial facilities need water systems that are both reliable and compliant. We provide customized commercial water treatment solutions across Maryland, Washington D.C., and Northern Virginia, designed to protect equipment, improve efficiency, and ensure safe, high-quality water for employees, customers, and operations.
We begin with full diagnostics to identify your water’s issues: hardness, iron, bacteria, acidity, chemical contaminants, and more. This ensures we build the right solution from the start.
Based on your water test, facility size, and usage patterns, we engineer systems that may include softeners, RO units, UV disinfection, sediment and odor filters, neutralizers, and more.
From drilling new wells to maintaining existing ones, assessing flow, performing repairs, or monitoring water quality, we’ve got all aspects covered. We’ll also assist with permit support where required.
Before investing in a commercial water treatment system, it’s critical to understand your facility’s water quality. That’s why we provide professional water testing services for businesses across Maryland, Washington D.C., and Northern Virginia. Our testing identifies:
Hard water minerals (scale-causing calcium and magnesium)
High levels of iron, rust, and sediment that damage equipment
Chlorine, sulfur, and other chemical odors that affect taste and performance
Corrosive or acidic water that shortens the life of pipes and fixtures
Harmful bacteria or contaminants that can compromise safety and compliance
Need deeper insight? We also offer advanced laboratory analysis for virtually any contaminant, ensuring your system meets health, safety, and regulatory standards.
From Washington D.C. office buildings to Northern Virginia hotels and Maryland manufacturing plants, our commercial water treatment services help you:
