Several councils and government ministries could be facing bills in the hundreds of thousands to fit essential filters to their drinking water supplies in the wake of Queenstown's cryptosporidium gastro outbreak. There are 60 confirmed cases of the parasite induced gastro, that can cause severe diarrhea, stomach cramps and vomiting. The national water regulator, Taumata Arowai, has issued 150 compliance notices requiring councils and others to install UV filters to protect the water from Protozoa, an organism that can cause of raft of nasty health issues. The cause of Queenstown's crypto outbreak has yet to be indentified but it's been revealed some of the networks that supply the town with water are not fitted with the compulsary filter. Steve Taylor from the national water regulator, Taumata Arowai speaks to Lisa Owen. [embed] https://players.brightcove.net/6093072280001/default_default/index.html?videoId=6338287340112
