Brylee Drive Reserve Wetland in Takanini. Construction of the wetland was completed in June 2017.
After a great effort by all involved, the Brylee Drive Reserve Wetland in Takanini was completed in June 2017. The 10,000 square metre wetland treats over 30 hectares of urban catchment, including a portion of the Southern Motorway which previously discharged untreated contaminants to the Pahurehure Inlet in the Manukau Harbour.
Morphum Environmental was engaged by Auckland Council's Healthy Water Group to undertake detailed design, tender and construction documentation, and to supervise the wetland's construction.
The design of the wetland applies our learning from other national and international projects to deliver a resilient and robust system which will provide long term water quality improvements whilst enhancing the landscape and biodiversity of Brylee Drive Reserve. This design has optimised the footprint through earthworks design and hydraulic controls with a final downstream cell of the wetland being subject to saline ingress on king tides. This will provide insights into the performance and function of constructed wetlands on the coastal margins and potential adaptation to rising sea levels.
With over 25,000 aquatic and terrestrial plants in the ground, it is now time to sit back and watch it flourish.
