You will need to design launching and recieving stations to accomodate pigging the line. Typical pipe arrangements can be found on the website. Good luck!!
A great resource for info on pumps is a book titled "Pumping Station Design" by Robert L. Sanks. It is often referred to as just Sanks. You can find it at:
