Municipal or Public Water Supply
Many industrial sites are served by a municipal water system, providing treated and pressurized water for domestic use, fire protection, and industrial processes. This is the most common and reliable source in urban and developed areas.

• Delivered through a public utility or water district
  
• Metered connection typically located at the property boundary
  
• Offers consistent flow rates and regulatory compliance for potable use
  

Private or On-Site Water Systems
In rural or undeveloped areas, the site may rely on a private well or an independent water system. These systems are designed to meet the specific needs of the facility but may require regular testing and maintenance.

• Includes drilled wells, storage tanks, and filtration systems
  
• May be used for non-potable or supplemental purposes
  
• Subject to local health department regulations and permitting
  

Confirmed Through Utility Maps and Site Plans
The type of water supply serving a site is detailed in utility service plans, civil engineering drawings, or records from the local water authority. These documents indicate the source, capacity, and connection point.

• Utility maps show municipal water lines and service availability
  
• Site plans identify meter locations, pipe sizes, and connection types
  
• Water provider can confirm service details and usage limits
