Groundwater Discharges

USD’s Groundwater Program

All reasonable alternatives to sewer disposal, such as legally permissible reuses, must be explored before discharge will be approved. When no other alternative for disposal of groundwater exists, USD may issue discharge permits for:

  • Groundwater from site remediation projects
  • Groundwater encountered during excavation

This Permit is a conditional Discharge Permit and approval of discharge is dependent upon available capacity in the sewer.

For specific requirements, limits, and fees for a groundwater permit please access the Groundwater Reference Sheet.
