I need films about environment protection and sewage treatment

[Santino Di Bernardino]

I'm lecturing a training course on environmental management, in Portugal 
and I am interested to complement the lessons with video film 
presentations, in order to show practical aspects related with treatment 
system and environmental problems, and promote dialogue and discussion.

I would like to get some videofilms concerning solid and 
liquid treatment systems, case studies, technology applications and 
other related subjects.

I thank you in advance 

Sincerely
