Michelle, a client of mine, told me recently that Paducah Water (PWW) gives a one time credit each year to customers that fill a swimming pool. She mentioned this after we were talking about our pools and I told her it cost me nearly $25 to fill our portable pool at my house. That's when she told me PWW gives a one time credit for that initial fill.
I called the water works and they confirmed that was the policy until the board changed it. So I got my credit of nearly $25 on my water bill. I'm sure if they advertised this they'd be flooded with calls each summer. At least, I've never seen it advertised and I read the water works newsletters from time to time that are included in the monthly bills.

Bill I am glad you got your credit! I have never made anyones blog before> Does that make me a celebrity now? haha
