Because of our increasing populations around the world, more and more of our clean drinking water is being used and contaminated. The world needs to take action immediately. Implementing one plan will not save our drinking water, but instead several different things need to come in to effect to preserve the world's clean drinking water.

One alternative we have is to make people implement a wastewater garden in their homes and businesses. A wastewater garden is a garden made up of specially chosen plants and soils that can dispose of our harmful wastes in a totally non-harmful way. The way it works is all of the greywater from washing machines, showers, tubs and sinks will drain into a holding tank, where the small amounts of oils are separated out. Blackwater from toilet waste can also go into the tank given proper treatment first. The wastewater is then pumped into the garden where the plants will essentially eat, drink and breathe away the contaminants found in the wastewater. Certain kinds of plants "purify" the contaminants into useful energy while clean water evaporates. All that is leftover from the wastewater is plant biomass, evaporated water, carbon dioxide and heat.

Another alternative to help prevent the wasting of clean water is to implement composting toilets that use virtually no water. One type of a composting toilet system is called the carousel. It consists of a fixed outer container and a revolvable inner drum or "carousel." The inner carousel is divided into four separate composting chambers with drain holes in the bottom. All of the excrement, toilet paper and vegetable scraps go into once chamber at a time. After the first chamber is filled the carousel turns to the second chamber, and so on until all four chambers are filled. In the warm, moist environment, aerobic microbes will, over time, transform the solids into safe and valuable oxidized dry humus, a stable nutrient for plants. The humus can be buried on your property to benefit trees and plants or a septic pumping contractor can remove it for you (Carousel 1-3).

This is also a fairly expensive system to start up, but will save people money in the long run and will benefit their trees and plants. People will also be conserving lots of clean water and helping to cope with the world's clean water dilemma.
