Here's one I bet isn't coming up in the city's water conservation contest. Oh, I have a bunch of them! When you order that cold soda or ice water when you dine out, you've noticed that the glass or cup has water condensing on the surface. Especially in the summer. If you dine out a lot, take some napkins and wrap around the cup. When done with your drink, place the wet napkin in a small baggie to prevent evaporation. Also put the remaining ice in the baggie too! Collect enough that you can squeeze the water out and use the water for your plants or to fill your swimming pool. If you have a small lot you might water your lawn too, but do it on the right days so as not to create a police investigation and explain that you've been smuggling water from Christina's!
Let's not forget the other recyclables being used for this! The napkin can be hung to dry and reused, thus saving countless trees and extending the life of our landfills. Or, it can offset the cost of purchasing personal cleansing items. The baggie can be reused too. No need to wash it and waste more water than you saved. Hang it in the sun and the ultraviolet light will sterilize it.
And a suggestion for Mayor Nelson. To stimulate more water conservation consciousness in the public, have the library do a movie festival featuring the movie DUNE.
