THE BRIEF

Water storage was required to support up to 1100Ha of new horticultural development on the Poutō Peninsula. The work was commissioned by the Te Tai Tokerau Water Trust, who has the objective to develop water schemes to enable the establishment of commercially viable and environmentally sustainable horticulture, providing economic and employment opportunities in the region.

THE OUTCOME

Te Waihekeora Reservoir, completed in 2024, stores 3.2Mm³ of water within a 43H geomembrane lined basin. One high potential impact classification (PIC) dam and four low PIC dams were built to form the reservoir, with a maximum retained height of 11m.
