A few dozen sensors can go a long way, for example a municipality can find that a particular pipe is consistently pushing 100gpm, despite serving residential customers that don't normally have that kind of even usage. This implys a leak on that section of pipe, making a root cause analysis (and shutting off just the worst leaks in the system, rather than the whole town) much easier to do.
