The problem with this source is that it is invariably 'dirty' and heavy with particulate that needs to be filtered out of the flow, before the LeakyPipe becomes the filter!   Filtering on these sources can be both expensive relative to the size of use and inconvenient.

Again pumping will be required to create a pressure of 1-2 bar at the LeakyPipe for LP12H to work properly (less pressure is needed for higher porosity pipes, but fewer and shorter lengths of LeakyPipe can be watering at any one time).
