Water Treatment | Plumbing | Well Pumps
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:
Prevent scale and mineral build-up in equipment and plumbing
Reduce maintenance and replacement costs
Extend the life of boilers, water heaters, and other appliances
Improve cleaning efficiency and reduce chemical usage
Lower energy and utility bills
Enhance water quality for drinking, production, or use in sensitive applications
Avoid costly emergency repairs and downtime

We provide full-scale commercial water treatment solutions including diagnostics, system design & installation (softening, reverse osmosis, UV, sediment/odor filters, neutralizers), well services (drilling, repairs, flow testing), and ongoing maintenance & emergency support.
We support restaurants, lodging/hospitality, assisted living & nursing homes, schools/childcare, retail & corporate facilities, manufacturing & industrial operations, offices, and government buildings.
We start with thorough water testing and analysis (hardness, iron, sediment, corrosion/acidic water, bacteria, chemical contaminants) to understand your facility’s supply. Then we design a custom treatment system based on your usage, facility size, and needs.
Good water treatment protects equipment (from scale, corrosion, bio-fouling), reduces maintenance and energy costs, improves operational efficiency, ensures compliance with regulations, and helps maintain product/service quality.
Yes — our services address both municipal and private well supply scenarios, including well-flow testing, pump/pressure systems, and full treatment system integration.
We offer support & maintenance plans that include scheduled inspections, consumable/filter/change-outs, monitoring, emergency repair service, system optimization over time.
We understand commercial operations can’t afford long downtime. We provide prompt emergency response for failures, contamination issues, or loss of water system function to minimize business disruption.
Common warning signs include — scale buildup on equipment or pipes, increased maintenance or downtime of systems like boilers/ HVAC, corrosion or leaks, water quality issues (taste, odor, clarity), higher energy costs or reduced equipment life.
Yes — we assist with advanced lab testing, monitoring, documentation to help your facility meet applicable water quality standards, occupational/safety codes, and operational reliability.
Reach out to us for a complimentary water analysis. We’ll assess your facility’s water profile, discuss your operations and water demands, then provide a custom proposal.
