Kōkiri Centre Greywater System presented at WaterNZ Conference

At the WaterNZ Conference in Hamilton on 16 October 2013, James Sukias (NIWA) presented a paper on the greywater wetland installed at the Kōkiri Centre at Whāingaroa (Raglan).

The greywater treatment system was designed and installed as a demonstration site and provides a real-world example of potential improvements to be made to marae wastewater systems through greywater diversion from existing wastewater infrastructure, and dedicated construction of greywater treatment systems.

The next issue of this newsletter will feature a full article on the work completed at the Kōkiri Centre. For more information on WaterNZ visit:
