Managed Aquifer Recharge in Kerikeri
The Far North gets plenty of rain in winter and far too little when it counts. Long dry summers, intense horticulture around Kerikeri and small surface-water takes leave the district short exactly when demand peaks, and managed aquifer recharge offers a way to even that out. By capturing wet-season flows and recharging them into a suitable aquifer, water can be stored underground and recovered through the dry months without the footprint of an above-ground dam.
LDE provides managed aquifer recharge and aquifer storage and recovery engineering across this part of Northland, from feasibility and source-water assessment through to aquifer suitability, recharge trial design, water-quality and clogging management, and the consenting that goes with it. Our work helps growers, councils and communities test whether MAR stacks up for their setting, then design and monitor a scheme that performs. For Kerikeri clients, that means a practical look at storing water when it is plentiful so it is there when the season turns dry.

How our Kerikeri team delivers managed aquifer recharge
Managed aquifer recharge in the Far North is really about timing. There is water to spare in winter and a shortfall every summer, so the question is whether a local aquifer can hold the difference. Our team starts with the feasibility case: how much wet-season water is available, whether the aquifer can accept and store it, and what quality the source water needs to be. From there we design the recharge method, the trial that proves it, and the monitoring that keeps it honest.
It is the same managed aquifer recharge capability we bring to water projects across Northland, where seasonal security matters as much as everyday supply.
- Feasibility studies and source-water assessment for wet-season capture
- Aquifer suitability assessment for recharge and recovery
- Trial recharge and aquifer storage and recovery (ASR) testing on small bores
- Water-quality and clogging management for small horticultural schemes
Water security and consenting in the Far North
A managed aquifer recharge scheme touches both takes and discharges, so consents run through Northland Regional Council under its regional and freshwater plans. Recharge water quality also has to satisfy national policy, so we design to recognised guidance from the start.
- Ministry for the Environment freshwater policy and the National Policy Statement for Freshwater Management
- Water New Zealand good-practice guidance for managed aquifer recharge
LDE managed aquifer recharge in the Far North
LDE brings managed aquifer recharge and aquifer storage and recovery thinking to a part of Northland where summer water security is a live issue for horticulture and small communities alike. As lifestyle and orchard demand grows around Kerikeri and the Bay of Islands, MAR is one of the options worth testing alongside conventional storage, and we help clients work through whether it fits their aquifer, their source water and their budget. You can see more of our regional water delivery on the projects page.
Common questions about managed aquifer recharge in the Far North
What is managed aquifer recharge and how could it help Kerikeri?
Managed aquifer recharge stores water underground by recharging an aquifer when water is plentiful, then recovering it when it is scarce. For the Far North that could mean capturing winter flows and drawing on them through the dry summer, easing pressure on stretched surface-water takes.
How is MAR different from just drilling another bore?
A normal bore only takes water out. Managed aquifer recharge deliberately puts water in and stores it, so the aquifer acts like an underground reservoir. That changes the assessment: we have to confirm the aquifer can accept the recharge and that the stored water stays usable, not just that it yields when pumped.
Who carries out LDE’s managed aquifer recharge work in Kerikeri?
Chartered Professional Engineers from our team, working with LDE water and groundwater specialists across Northland and beyond.
How do you stop a recharge scheme from clogging up?
Clogging is the main operational risk in MAR, so we match the source-water quality and any pre-treatment to the aquifer, design the recharge rate to suit, and build in monitoring and maintenance. On small Far North schemes that usually means keeping the system simple and testing it through a trial before committing to full operation.
