About the project
An ecosystem services report commissioned by Living Water identified widespread use of detention bunds as a potential solution for slowing water flows, removing sediment and improving overall catchment resilience. Engineers were engaged to design and build detention (earth) bunds in flow paths to collect and slow the release of stormwater on two farms. The ability of these structures to reduce peak flow and capture sediment in the Northland farming landscape will be assessed.
Once the performance of the bunds and their designs have been assessed, we will evaluate the cost effectiveness and water quality outcomes of using them throughout the entire catchment. In turn, this will determine whether detention bunds (or similar solutions) can effectively manage peak run off in Northland.
