Short summary
Waiwera in New Zealand is a small coastal village with a geothermal reservoir underneath. Hydrogeological models support water management by providing insights into sustainable extraction from the system. It is artesian and the geothermal water is of meteoric origin percolating down to sufficient depth getting heated. It rises through a fault zone into the shallow and leaky aquifer. Most recently the springs have restarted discharging geothermal water on the beach.
