The Things They Save Here in Alemanya

This is not really new to me...urine saving. My mother used to
collect cans of urine to water her plants but it was so revolting
to see the cans piled in our small garden ready for use. The smell
was also equally revolting when one passed by the potted plants
even with their beautiful flowers in full bloom. I'm just wondering if
this urine-diversion system is used now in the Philippines.
What a big help if they could install them all over the country
with a big poster saying..."Di Bawal ang Umihi Dito."
Help conserve energy.
Below is a small info on the use of eco-san toilet or simply urine-
diversion system.
How do the urine-diversion toilets work?
The urine-diversion toilets have two separate compartments in the toilet bowl: one for urine and one for faeces and water (together also called brownwater). The urine is collected without flush water, by means of a valve located inside the toilet seat. When the user is seated, the valve is opened by pressure on the toilet seat, allowing the urine to flow to the storage tank. The valve closes again when the user stands up, so that the subsequent flushing water does not enter the urine pipe but drains off through the brownwater outlet in the rear.

Is the collected urine being reused at the moment?
Yes, complete reuse started right now within the BMBF-funded research project SANIRESCH. The urine is used for fertilising experiments as well as for MAP precipitation. Till now, on some occasions urine was collected by various universities in the vicinity (Bonn, Aachen, Giessen) for research purposes. SANIRESCH has six research partners and started in July 2009 to investigate urine, brownwater and greywater treatment and reuse.
