Christchurch City Council, NZ evaluates the impacts of eClean Bioreactor on waterway health

Christchurch City Council, NZ eClean Bioreactor Waterway

In Progress

The Smart Christchurch team worked with device inventor Ngarie Scartozzi on a real-world trial on the Ōtākaro Avon River. The eClean Bioreactor is powered by solar panels and filters water through an internal microbiome. This treatment process removes E.coli, nitrates, and phosphates from the water supply. Christchurch and Scartozzi are measuring the device's effectiveness before expanding its use to areas including local farm drainage.
