How about no water use to flush your toilet? Here's is a company that I discovered 30 years ago. You have to think outside the bowl(box).
$this->bbcode_second_pass_quote('', 'C')LIVUS MULTRUM, INC. was founded in 1973 to develop the
Clivus Composting Toilet. The Clivus system, invented in Sweden in 1939, is a healthier alternative than the flush toilet. Conventional waste treatment systems create pollution by their design. For instance, the leach field of the septic system puts nutrients into soil at a level too deep for plants to use. Eventually, these nutrients reach groundwater, rivers, lakes, etc., where they have damaging effects on aquatic environments and on drinking water. The sewage treatment plant creates pollution with both of its end products.
First, the effluent (i.e., the liquids, including the water that carries matter to the sewage treatment plant) is discharged into rivers, bays, and oceans. Since it contains plant nutrients, among other things, it, too, ruins aquatic environments. The second product of the sewage treatment plant—sludge—contains thousands of substances, including heavy metals, dioxin, and PCBs that make it toxic. In spite of its toxicity, sludge is widely used as fertilizer.
Alternatively, the composting toilet allows the nutrients in human excreta to be captured and readied for use again as fertilizers—instead of mixing them with water or toxic industrial chemicals. The composting toilet makes it unnecessary to pollute water and soil, or to use clean water to flush toilets.
For more than 30 years, Clivus Multrum, Inc. has provided environmentally sound waste treatment solutions in North America and beyond. In many remote areas, Clivus systems are less expensive than conventional waste treatment systems. In all instances, Clivus composting toilets and greywater systems eliminate pollution and protect natural resources. Clivus offers a range of services to ensure that its technologies will be properly designed, installed and maintained. Clivus clients include federal, state/provincial, and local governments as well as commercial and residential customers. Clivus Multrum is a member of the US Green Building Council.
is a highly effective, simple method for using greywater for plant irrigation. The Clivus Greywater Systems consist of a dosing basin, effluent pump, water level controls, and covered irrigation troughs. Easy to maintain, there are no filters to clog or change.
As greywater flows into the dosing basin, level controls in the dosing basin engage the effluent pump to fill irrigation troughs, bringing greywater evenly to the surrounding vegetation. Water, soap residue, and the small organic particles carried in greywater are brought directly to plant roots and soil organisms, which make use of the total contents of greywater.
