The Design of Water Saving System for College Dorms

Li, Bin

We designed a set of water saving system for college dorms based on the current college water use status. This system mainly included a water collection tank and the enclosed sanitary-wares. We designed the subsidence area on one side of the water collection tank so it’s easy to clean the sludge and the allocation of water-saving effect demonstration system. There are no devices in the water collection tank for eliminating the peculiar smell of wastewater, heterochromatic carbon absorber and ozone generator. In order to ensure the smooth implementation of the system, in view that the peculiar smell and different color of the wastewater affecting users mood, in order to reduce the users conflicted emotion, according to the shortage of current toilet sanitary-wares, we designed an enclosed squats bedpan that using the user’s gravity to expansion and it will be closed automatic when users left. We also designed an enclosed toilet that using the user’s gravity to expansion and it will be closed automatic when users left. And we designed an enclosed urinal that using the user’s gravity to expansion and it will be closed automatic when users left. And according to the lower pressure situation of the upper water collection tank, the special structure of the squats bedpan and toilet in this project don't need a large scouring force, rejected the “siphon principle” that widely used in the traditional design scheme, reduce the required water, improve water saving effect.
