Pumping Urine from Urine Diversion Toilet to a Cultivated Field

Published on by in Academic

Hi all

I would appreciate some advice regarding my latest project. I have installed UDDT toilets in Namibia. The urine production is around 170-200 l per day and I will collect about half of it (due to restricted storage capacity) and let the remainder soak away.

After allowing for 30 days of storage, I want to pump the urine to a cultivated land area 200m away where it will be used as fertiliser. I know there are several risks with pumping urine (or conveying urine), mostly due to struvite formation. Does anyone have any experience in this? Any advice would be much appreciated!
