•'Streams from which water supplies are tal\en without imrifieation 

 sliould not receive any fecal matter, sewage, sewage eilhieiit or wastes tliat 

 will render tlie water a menace to health or otherwise impair its natural 

 (piality. 



"Streams from which water suiiplies are taken and used after jiurifica-
