Hmmm. Gee, anybody know what the pressure would be in Rome's municipal water system? I happen to know that 6" to 12" PVC water mains in the United States are generally rated for use at up to 150 or 200 psi, and that municipalities here try to maintain pressures of at least 50 psi in their systems. Are there pumps, which would be available to these charaters, that will move large volumes against pressure of, say, 70 or 80 psi?
