Current Flowback Water Management
Approaches
• Evaporation in pits/ponds
• Trucked off-site for:
− Reinjection into Class II disposal wells
− Treatment at a commercial wastewater treatment plant or a POTW if disposal wells are not available.
• Direct reuse for fracing by diluting it with makeup water-considered best practice
• Treatment for reuse or surface discharge
