The Hekeao/Hinds community in Canterbury (south of Ashburton) leads New Zealand's largest managed groundwater rehabilitation project, delivering environmental and cultural benefits.
What is Managed Aquifer Recharge (MAR)?
MAR involves intentionally recharging aquifers through infiltration basins that function as permeable ponds. Clean alpine water from the Rangitata River flows through irrigation infrastructure into basins where sediment settles in forebays before water percolates downward to recharge groundwater systems naturally.
Project Leadership & Rationale
Peter Lowe, Chair of the Hekeao/Hinds Water Enhancement Trust, states: "This situation isn't unique to our catchment, but our response is very much leading edge."
Historical intensive farming degraded underground and coastal water resources. Under Canterbury's Plan Change 2 and the Government's Essential Freshwater package, catchment action is mandatory to continue farming operations.
Lowe emphasizes the initiative addresses both economic sustainability and recreational values: "This isn't just about farming...its also about ensuring future generations can swim and fish in rivers."
Project Progress & Achievements
- Initial pilot site (2016): Successfully reduced nitrate concentrations and raised groundwater levels
- Current operations: 16 additional sites now functional
- Environmental partnerships: Collaboration with Arowhenua Runanga for mahinga kai improvements; lizard habitat created; wetland enhancement underway with anticipated Kowaro/Canterbury mudfish transfer
