To all;
I am seeking some help. I have designed out a small subdivision and placed my catch basins a part based on a past design requirement that I learned. Well, the local authority wants the CBs every 400 ft which seems a little far for my design application. I have been using the Federal...

I am working on a water distribution line for a small subdivision of 11 homes. The architect has been working with the municipality and they have asked for a 6" DI line to the fire hydrant. I was planning on designing the line to the fire hydrant with a 2" blow off assembly for dead end...
