The rest of my plumbing problems:

Man from water district just left. He had arrived and examined the meter before calling me. The verdict? We do not know. I had the outdoor faucet knob turned off on the outside and the master on the inside. The meter was not moving. I turned on the washer and the meter moved. Perplexed? So are we. He said I can call a plumber if I want. I wonder if the outside faucet is broken? In the meantime, I will string all.my hoses together and hope they will be able to water the plants in front.

About 30-50 gals per day depending on size, temperatures and exercise level.  Three horses was quite a drain.  

Did they check the main line?

Did he check meter flow per minute?  In other words when you use water is more water flowing through the meter than into your house?  I can't remember exactly how, but they measured the meter flow to the volume of water.  Discovered a deep leak in our pipe from the meter to the house.  Our neighbors leak was the same only his was under the road and ours was in our yard.

Good luck.

If they find a leak ask them to forgive the bill.  They would rather see it fixed than have an unusually high charge go for a customer.

Is it possible they misread the meter?  If it was real usage the water had to go somewhere.  Did they suggest putting a camera down the line to see if there is a break?
