 In the blog post, Pumping pressurized fluids to high altitude for the space tower and for fighting forest fires, Page 3: achieving ultimate laminar flow, I discussed using laminar flow to achieve long distance water streams, either with piping or without. 

 If we are to achieve it without piping over kilometer distances then we can use the staging idea to have laminar flow inducing devices along the flow path along with the staged pumps. This would reduce the length the water had to remain laminar while not constrained within a pipe.

 For the method that does use piping, some notable recent research is that flow that has turned turbulent can be converted back in laminar flow:

New approach can save up to 95 percent of energy used for pipelines.
Study proves that turbulent flow can be destabilized so that it turns to an energy-saving laminar flow

 Also, notable is that flow in microfluidic channels are commonly laminar:

 Then you would use large numbers of the microchannels bundled together to get the needed water flow.

UPDATE, 1/11/2020:

 The possibility of raising the pipe or the free water stream to high altitude in stages, also raises the possibility of covering the needed horizontal distance in stages. This is important because of having to keep a pipe aloft horizontally over kilometer distances raises a significant weight issue.
