As for metering, those homes that use two separate water supplies, each has a different meter.

Usage if each is detailed on your monthly bill.

Also, if your irrigation usage is considered unusual, you will get a call. Our usage was double one month. A sprinkler head had broken, and we had quite a geyser in the yard. Fortunately, a neighbor had also let us know, coincidentally the same day we got the call from The Villages. The head was located on the side of our house, out of view. Also, ran early in the AM, so not many up to see it.

Worth a periodic check to make sure all is in order.
