Operation Philosophy for Water Conveyance / Transmission Systems

Dear All

Please share your views and published literature on the operation philosophy for water distribution / transmission systems.  It could be for both municipal as well as cross country.  What the industry practices around operations.  

I have fair bit of idea on the O & M aspect, but wanted to know more about the operation / control philosophy for pipelines.

Thank you.

Best Regards
