I need to design and layout an extension for water main in Illinois, this Extension would serve a collage apartments that consists of 30 apts and a clubhouse. along with designing the water main, a fire hydrant needs to be designed too. I know this forum is for engineers, and I am going to be in a matter of months, I am simply asking for tips on how to design this water main, for example, where the extension of the water main should start? how long the water main should be? where can I find the specification and standards for designing a water main? how to calculate the peak flow demand, and daily average peak flow? I just simply needs guidance on how to figure out those questions, I have been searching about them for quite some time, and I found bunch of info, but I don't really know where to start. I will provide the site where this water main extension should serve.
