What is Non-Discharge?

  • Non-Discharge is the treatment of wastewater and disposal/reuse
  • Non-Discharge is NOT the discharge to surface waters of the state or utilization of a sub-surface disposal system (i.e. septic system with leach field)
  • Types of Non-Discharge Permits:
    • Wastewater Irrigation
    • Single-Family Residence Wastewater Irrigation
    • High-Rate Infiltration
    • Other Wastewater
    • Closed-Loop Recycle
    • Reclaimed Water
    • Residuals Management
  • Non-Discharge Disposal Methods
    • Spray/Drip Irrigation
    • High-Rate Spray/Drip Infiltration
    • High-Rate Basin Infiltration
    • High-Rate Rotary Infiltration
    • Closed-Loop Recycle
    • Reclaimed Water Reuse
    • Reclaimed Water Irrigation
    • Other Methods
  • Domestic, Commercial and Industrial Facilities that Need a Non-Discharge System
    • Unable to connect to local sewer system
    • Unable to obtain subsurface system permit
    • Unable to obtain discharge permit (NPDES)
    • Utilize reclaimed water to replace potable water
    • Recycle systems to reduce overall water usage
  • Why Non-Discharge is Important?
    • Allows wastewater treatment and disposal while avoiding discharge to surface waters
    • Allows development in decentralized areas
    • Allows development in areas with unsuitable soils for subsurface disposal
    • Allows development in nutrient sensitive waters
    • Reuses a waste as a beneficial product
    • Replaces potable water
