Now, I'd have to say that gentleman probably knew more about water schemes than the whole of our Health Committee would ever know about water schemes, so why we refused to go and listen to someone like that is beyond me, because it was the best possible education we could have got on this. He was able to tell us that there was somewhere between 70,000 and 75,000 of these small rural water schemes across the country, and, you know, they range. They range from a farm that has a scheme that supplies the main farm house and a worker's cottage or the shearers' quarters through to schemes that might have a number of small lifestyle blocks attached to them and a main farm. Some of the schemes provide water for irrigation and for stock feed, as well as drinking water. And in those instances, the end users take the responsibility of putting in place an end-point user filter, such as the UV light filters that you can get. A lot of these schemes are collectives, are unincorporated societies. They're groups of farmers that have got together and they pay a small amount and they look after them together. They are practical, sensible people who find solutions for drinking water, for livestock water, for irrigation water on a small scale right across the country. They've been doing it for decades and they continue to do it in a safe and sensible and pragmatic way.
