Public television is, by definition, supposed to educate viewers as well as entertain them.

That’s how I’ve always understood public TV’s role. Well, on Thursday night, Texas Panhandle public TV viewers are going to get an education about something many of us have taken for granted.

It’s about water. How we acquire it. The value it brings to our economic infrastructure. Its future use. Ways to preserve and conserve it.

Now for a bit of disclosure. I had a teeny-tiny hand in this project. I was a reporter for a segment that Panhandle PBS assembled for this project, which was done in conjunction with other public TV stations around the state.

The program, “Texas Perspective: Water,” airs at 7 p.m. on Panhandle PBS. That’s Channel 3 for cable users; Channel 2 if you don’t have cable in the Texas Panhandle.

The program will air throughout the state because it is a state issue. Every region of Texas has reason to be concerned about the future of its water. Some regions are doing a better job of managing this resource than other regions.

I don’t want to give any of this special away here, on this blog post.

Instead, I merely want to call attention to an important public affairs program that will remind Texans from Hartley to Harlingen and from El Paso to Orange that water is absolutely critical to our survival.

It doesn’t get any more educational than that.
