Public Sewer Connection
Most industrial and commercial sites in urban or developed areas are connected to a public municipal sewer system. This system is managed by a city or county utility department, which handles wastewater collection and treatment.

• Wastewater is transported through underground sewer mains to a central treatment plant
  
• Subject to municipal usage fees and sewer discharge regulations
  
• Connection point is typically located at the site boundary or in the adjacent right-of-way
  

Private or On-Site Sewer System
In rural or undeveloped areas without public infrastructure, properties may use private on-site systems, such as septic tanks, lift stations, or small treatment plants. These systems require regular maintenance and environmental compliance.

• Septic systems include tanks and drain fields for wastewater absorption
  
• Private sewer systems may serve individual properties or industrial parks
  
• Permits and inspections are typically required from local health or environmental departments
  

Confirmed Through Site Plans and Utility Records
The type of sewer connection—public or private—is indicated on civil engineering drawings, utility plans, or by contacting the local sewer authority. These sources confirm infrastructure availability and connection status.

Property deeds or development agreements may include connection rights or obligations

Site plans show sewer lines, manholes, and tie-in locations

Municipal GIS systems or planning offices verify service zones
