  Rainwater harvesting & greywater recycling

Between 2014 and 2017, eight rainwater harvesting and greywater recycling systems in commercial buildings across New Zealand were investigated. This was done using a multi-disciplinary case study approach, utilising engineering, environmental, social and economic expertise. 

An Advisory Panel was formed to support this research. Together with the BRANZ team, this panel established a framework for future uptake in New Zealand, outlining today’s situation and a 30-year vision.
