Pumping Urine from Urine Diversion Toilet to a Cultivated Field

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! Regards Megan
