That's really not that much water if you've ever worked around utilities. It's about the equivalent of a half inch copper line.

From a quick googling a residential sprinkler system uses between 12-30 gallons per minute. So about half of what it takes to run a sprinkler system

Wow. Then wouldn't the fixtures downstream (ie where the water ends up, faucets etc) notice a big drop in water pressure?

The farther you get from the source the lower the pressure will be. A home only really needs like 40psi to operate correctly and many times has 100+psi that needs to be reduced because of this.

Also a small leak is not going to noticeably drop water pressure in a 6" main
