Challenges• Focus away from groundwater recharge to DPR
(water recycling criteria for Direct Potable Reuse through Raw Water Augmentation by December 31, 2023)
• In-City Construction• Hyperion Advanced Water Treatment Facility
– Brine Management– Equalization Storage
• Complex groundwater governance structure• Inter-jurisdictional planning• Basin Specific Storage and
Augmentation rules
