The control of water by a single entity in both Scotland and Ireland is being seen as an example of what could work in New Zealand.
New Zealanders take fresh drinking water for granted - we assume we'll just turn on the tap and it will be fine.
But in reality 70 percent of people living in small towns of up to 500 people get water which doesn't meet drinking water standards.
An organisation that keeps an eye on the state of New Zealand's water says the quality of our drinking water is so bad in places, it could lead to mass death.
Water New Zealand says if we don't do something soon, we'll see another contamination like the Havelock North one - and that in turn could destroy our tourism industry.
WEFTEC, the Water Environment Federation’s Annual Technical Exhibition and Conference, is the largest conference of its kind in North America and offers water quality professionals from around the world with the best water quality education and training available today.
