Anyway they want to get compensated for the watering of the "Island", its about 20 feet across and has 3 sprinkler heads fed from a 1/2 inch line at about 85 PSI. Here are her emails and my response.

Hello Hugh,
Mike finally figured out that the island water comes on about 3 or 4 a.m. for 10 minutes. The timer for the island sprinklers is on our front lawn in the plants. Our water meter on the side of our house spins when the island is being watered. For 10 minutes of watering the island it is about 783 units of water.
I called the Water Company to get an estimate of the cost. I spoke to April, who stated it is hard to get an accurate cost for watering the island as there are other things involved in the water bill (energy charge, infrastructure, surcharges and you get charged a higher price if you for over certain amounts of units (over 8, over 25, etc.). However, April did say that 10 minutes of landscape watering every day is a lot of water, and the cost for that could be close to half our monthly bill. Underline by me, yeah right!!
I wouldn't care if it was $5 or $6 a month, but it appears as if it is costing a lot more than that.
Based on it being watered for 10 minutes a day every day, and the meter numbers running at 783 units for the 10 minutes. That is about one gallon of water supposedly, and a gallon costs anywhere from .80 cents to over $1.00. So if a month has 31 days, and it uses a gallon per day at $1.00 per day, that is $31.00, plus factoring in energy usage, etc. it could be $35.00 or so per month just for the island.

You may want to double check your math. The water charges start at $0.80/unit of water and go up from there. One unit is 748 gallons (which is 100 cubic feet of water by the way), so at the first tier, it would be $0.00107 per gallon. At 80 cents per gallon, I'd be taking showers in Evian, it would be cheaper. If it ran for 783 units, that would 585,684 gallons in ten minutes, or 3,514,104 gallons per hour. A fire hydrant is only designed to deliver 18,000 gallons/hour.
