004324000 | Manual selection of the amount of flush | 89 |
20080216223 | Water conservation apparatus - A water conservation system is provided public and domestic lavatories. The system includes a distinctive flush mechanism of two features. One of these features entails a “treatment button” which, upon depression, will cause to emit a fluid compound into urinated wastewater decolorizing and sanitizing it and bringing it back to its original, colorless, odorless condition. Accordingly, potable water is not used for flushing. The urinated wastewater is “treated” and, so, remains through subsequent “treatments” until such time when solid waste is deposited necessitating a conventional flush utilizing the flush lever and usual water use. The savings in volume of water is realized upon considering the number of times the “treatment button” is executed and potable water is “not withdrawn.” The system is revolutionary in that it dispenses with a “necessary flush” each time the toilet is used. Moreover, this novel system addresses the recurring local, and national, drought emergency situations. | 09-11-2008 |
