Closing address

These remarks are the observations of a nonexpert. I am neither an engineer nor a water supply man by either training or inclination. My remarks are those of an interested and committed observer, who believes strongly in the importance of what is being done but at the same time has the luxury of being able to take a more detached view of the effort. These remarks are meant in this spirit.

First I have seldom encountered a group of professionals that are as dedicated and committed to their work as the group represented here. All the members have a sense of 'righteousness* that is unusual in any profession, except perhaps in the medical profession. This comes from the firm conviction that what you are doing is of great benefit to humanity, and this is undoubtedly right. It is a strength in that it gives both the energy and the drive to overcome the many obstacles, but it is also a weakness. Your conviction of the righteousness of your case often leads to an intolerant attitude towards people who do not share your fervour. It also leads you to be less critical and to be less accepting of the inputs of other disciplines - particularly economists, of which I am one.
