Definitions

  • the invention pertains to a system for storing and distributing water, the system comprising a water tank having a fresh water inlet, a collected water inlet, and a main water outlet; a fresh water conduit connected to the fresh water inlet; and a main drain connected to the main water outlet, wherein the system does not have a water tank bypass connecting the fresh water conduit to the main drain.
  • the water used on the wash basin is re-used on the toilet bowl, and therefore, less quantity of water is required for the autonomy requested.
  • the size of fresh and waste water tanks can be then optimized taking into account the recovery operation. Less fresh water is needed to cover the basin and bowl functions (smaller fresh water tank), and so less water will be also kept with human effluents (smaller waste water tank). The system allows reducing the size of the tanks and the weight on the vehicle.
  • Figure 1 shows a known sanitary facility with a grey water recovery system. These facilities are currently implemented in the Euro tunnel shuttles.
  • FIG. 1 illustrates the sanitary facility 100 of a railway carriage.
  • the main components of sanitary facility 100 are a main fresh water tank 102, an intermediate fresh water tank 104, a wash basin 106, a toilet bowl 108, a waste water tank 110 and a grey water tank 112.
  • the grey water tank 112 is used to recover the water coming from the wash basin 106 to flush the toilet bowl 108.
  • the sanitary facility 100 comprises three filters 114 to 118.
  • the first filter 114 is located between the wash basin 106 and the grey water tank 112
  • the second filter 116 is located inside the grey water tank 112
  • the third filter 118 is located between the grey water tank 112 and the toilet bowl 108.
  • the invention also relates to a sanitary facility comprising the afore-mentioned water storage and distribution system; a wash basin having a basin drain connected to the collected water inlet; a toilet bowl having a bowl inlet connected to the main drain; and a fresh water tank having an outlet connected to the fresh water conduit.
  • the sanitary facility further comprises a wastewater tank having an inlet connected to the water evacuation outlet.
  • the invention also relates to a vehicle, and in particular a railway carriage, comprising the aforementioned sanitary facility.
  • FIG. 2 shows a sanitary facility 200 according to the invention.
  • the sanitary facility 200 is installed in a vehicle such as a railway carriage.
  • the main components of sanitary facility 200 are a fresh water tank 202, a wash basin 204, a waste water tank 206, a toilet bowl 208 and a water storage and distribution system, namely a grey water recovery system 209.
  • the grey water recovery system 209 has a grey water input 210, a fresh water input 212, a waste water output 214 and a flushing water output 216.
  • the grey water input 210 is connected to the drain 218 of wash basin 204.
  • the fresh water input 212 is connected to the outlet 220 of fresh water tank 202.
  • the waste water output 214 is connected to the inlet 222 of the waste water tank 206.
  • the flushing water output 216 is connected to the inlet 224 of the toilet bowl 208.
  • the fresh water tap 226 of the wash basin 204 is connected to the outlet 220 of fresh water tank
  • the central element of the grey water recovery system 209 is a grey water tank 230.
  • the grey water tank 230 has a fresh water inlet 232, a collected water inlet 234, a main water outlet 236, and a water evacuation outlet 238.
  • a fresh water conduit 242 connects the fresh water input 212 with the fresh water inlet 232.
  • a fresh water pollution prevention valve 244 and a fresh water feed valve 246 are located in the fresh water conduit 242.
  • the collected water inlet 234 is connected to the grey water input 210.
  • the collected water inlet 234 is arranged at the top of the grey water tank 230 next to the fresh water inlet 232, similar to the prior art solution shown in Fig. 1 .
  • a main drain 248 connects the main water outlet 236 to the flushing water output 216.
  • a non return valve 260 is located in the main drain 248.
  • the system does not have a water tank bypass connecting the fresh water conduit 242 to the main drain 248.
  • the water evacuation outlet 238 is connected, via an evacuation valve 262, to the evacuation output 214.
  • a grey water filter 286 is fitted inside the water tank 230.
  • the filter 286 may be accessed via a removable filter cap, for filter cleaning.
  • the filter 286 is located at the bottom 290 of the water tank 230.
  • Grey water GW coming from the wash basin 204 enters the grey water tank 230 via the collected water inlet 234. If a toilet flush is required, the grey water GW leaves the grey water tank 230 through the main water outlet 236, transits through the non return valve 260, and finally goes to the toilet bowl 208. If no grey water is available in the grey water tank 230 for the flushing, the opening of the fresh water valve 246 is triggered such that grey water tank 230 is filled with fresh water coming from the fresh water tank 202. This fresh water will then leave through the main water outlet 236 for flushing the toilet bowl 208.
  • the non return valve 244 no grey water GW can flow back from the grey water tank 230 to the fresh water tank 202. Accordingly, bacteria and other pollutants cannot cross from the grey water tank through to the fresh water tank.
  • the non return valve 244 is designed according to the standard EN 1717.
  • the grey water tank 230 will fill up. Thus, the opening of the evacuation valve 262 is triggered, so that the content of the grey water tank 230 will be evacuated to waste water tank 206.
  • FIG. 3 A second embodiment is shown in figure 3 .
  • the elements similar to those of figure 2 are referenced with the same numbers.
  • the collected water inlet 234 is arranged at the bottom of the grey water tank 230.
  • this collected water inlet 234 reaches into filter 286, so that the grey water GW is filtered and temporarily stored in the grey water tank 230.
  • An air gap 289 is present between the collected water inlet 234 and the fresh water inlet 232.
  • This air gap 289 fills the space between the grey water surface and the top of the grey water tank 230.
  • the air gap 289 acts as a barrier for contaminants in the grey water GW, which are thus prevented from reaching the fresh water inlet 232. Accordingly, the air gap 289 can be qualified as a contaminant spreading inhibitor.
  • the inventive water storage and distribution system and corresponding sanitary facility stand out thanks to their small tank size and thus small weight, their reliability and small number of components, the protection against fresh water pollution, and the easy cleaning.
  • a further advantage is the use of a single filter for the whole system.
