Much of the country is suffering from either a shortage or a surplus of water. Clark was recently talking to some TV producers looking for a new angle on the drought story in Georgia. He thought we should be focusing on how to reduce our consumption of the existing water supplies, rather than on the fact that there's been too little rain. Clark believes there needs to be more emphasis on greywater systems. These are methods of water conservation that reduce consumption by about 35 to 40 percent. The idea is simple: Water is first used in the household for drinking, washing dishes and showering. It is then partially treated and recycled for landscaping, for use in toilets or whenever there is a need for non-potable water.

Meanwhile, Clark recently read about a high school in North Georgia that's conserving water by replacing water-based urinals with ones that don't use water. The military base where Clark trains as a volunteer state guardsman did this several years ago too. The filters used in waterless urinals are so efficient that there's no odor. In the home, you can install low-flow showerheads that use a blast of air to simulate a strong stream or use water-conserving toilets. Clark's home has a European-designed toilet that conserves water by having two buttons: One for a minor flush and one for a major flush. As Clark says, this is a G-rated show -- so use your imagination to understand when to use which button! As an aside, did you know that the Las Vegas Strip uses only 3 percent of the water in Nevada? Most of it is being sucked up by home owners trying to have green lawns in the desert. Now there are incentives for home owners to use rocks to landscape their lawns instead of having grass. Once again, the problem is on the consumption side -- not the supply side.
