Following is a short overview of the current status of the system I am building for reusing shower water at home, especially for the toilets. The system is still being involved, and I will describe in the blog future enhancements.
A short video that shows how the water are accumulated is available at: http://www.youtube.com/watch?v=EYHzrQ627DQ. A video showing the first prototype of the system is available at: http://www.youtube.com/watch?v=D0JIirw_4O4.
To collect the water from the shower, I built a lifted portable shower basin, which allows to use a small plastic box beneath it to collect the water while taking a shower. The box also includes a floating switch that is activated when the box is being filled. The switch activates a 12V pump that is pumping the water into an accumulation tank.
Pumping the water from the accumulation talk to the toilet is done manually, using fuel hand pump. Future enhancement will be to either use electric pump of to put the talk high enough to use gravitation. The main problem with such solution is that cleaning of the tank will become more difficult
The following pictures show the portable lifted shower basin, the pump and the accumulation tank:

Main system components and usage steps:
- A lifted and portable shower basin to allow collecting the water beneath it:
- Since the shower basin is lifter, I had to use a lifted shower head, using a “S” shape shower head:
- When taking a shower, I put a small plastic box beneath the lifted shower basin to collected the water. The plastic box includes a floating switch to control the pump operation:
- During the shower, the water are pumped from accumulation tank:
- When using the accumulated water, I pump the water (manually for now) from the accumulation tank to the toilets tank:
Electric supply:
As the pump uses 12V DC, I installed the required power supply in the bathroom:
