Limitations to Conventional Systems

• Onsite wastewater system facts
• 25 US population use these systems
• 50 of North Carolinians rely on them
• Soil is the largest treatment plant in the state

11
Conventional System Limitations

• Larger lots
• Extensive site disturbance
• Difficult to retrofit onto difficult lots

12
Water and Environmental Quality Issues

• Nutrients
• Bacteria
• Stormwater runoff
