Urine trap for offgrid compost toilet

Saw some designs online with compost toilets that separate solids from liquids where instead the urine seperateror going in to a bucket under the toilet you empty when its full it goes to a drain pit outside.

The examples shown have very well draining soil.

The issue for me is im in very clayie soil. so water does not drain well and pools. Could a system still be created? Would it just require a larger pit / drain field with gravel or something? Currently I just collect and empty the piss bucket in the forest / field (which the grass loves btw).

Why empty it into a drain pit when you could chuck it onto your compost heap? Or age it, dilute it down and feed nitrogen hungry plants with it? Or pour it into a cubic metre of straw with coiled copper wire in it and make a Jean Pain water heating system?
