Alternative methods for waste disposal should be investigated to conserve water.
The History Channel's "Modern Marvels" series includes a terrific program on plumbing history titled, "Plumbing: The Arteries of Civilization." (A videotape can be obtained for $19.95 by calling 800-408-4842 or online via www.historychannel.com.) My enthusiasm for the show is in no way diminished by the fact that I appear in it as one of the talking heads. But I would sing its praises even were that not the case, because the producers did a fabulous job of glorifying this industry of ours.
The program first aired in September 1998 and has been rerun, I believe, three times as of this writing. I'm uncertain because I have no way of knowing when it pops up on the broadcast schedule. (To my annoyance, the cable TV company covering my area does not carry The History Channel.) I always find out after the fact when calls or messages come in from acquaintances saying they saw me on TV.
