Everybody’s concerned about Hurricane Sandy and you can’t go five seconds without being reminded on how to prepare — but one thing in particular has stuck in my craw: stocking up on water.

It’s true that having water on hand is a good idea, but it largely depends on where your water comes from. If you rely on a well that uses electricity then you could have a problem if the juice goes out. But many people with a municipal water supply — like in the town where I live — are unlikely to have any trouble.

Without getting into the nitty gritty, my water does not move around by electricity, but by the pressure created by a water tower. As long as they keep the tower filled we’ll have water pressure. They don’t need to pump it all over, just up the tower — and there are generators in case of power failure.

Unless we have a gravity failure, we’ll probably have water.

Are there things that can go wrong? Of course — but losing water is very unlikely. Just try explaining this at home. My wife kept asking over the weekend if we should buy water and I kept saying no — until I finally gave in and went to Price Chopper at 5:30 this morning.

In the parking lot I met a man with a cart full of water. Did you leave a few bottles for me?

“Yeah, there’s a little left. You know, I’m only here because my wife is driving me nuts about having bottled water in the house. She doesn’t understand where our water comes from!”

I relieved him of his shopping cart — most of the carts in the corral were tied up so they wouldn’t scoot off in the wind — and hit the water aisle.

I went up to the night cashier, a Russian man who’s always the cashier when I go in there at odd hours. He looked into my cart.  “You have a lot of water.” He pronounced it “vawter.”

“Yes. My wife. We won’t need it, but this will make her happy. And I won’t have to listen to her go on about the water.”

He thought about that for a second. “Then that is a small price you are paying.”

Agreed.
