Water and Wastewater

I believe it is wonderful that ASCE has now created this forum for exchanges of information and ideas among its members. 

For several years now, as a retired Professor of Civil and Environmental Engineering, I have contributed what I hoped were useful educational materials to the American Chemical Society member's blog. Entitled 'water and wastewater slide shows', this often whimsical material has been freely distributed to all those interested in the technology - and history - of what was once known as 'sanitary engineering'

It is my hope that some of my CE colleagues may also find these materials useful and, possibly, even worthy of correction.
