Thanks for your question and I apologise about our delay in responding to your question. The portable fire fighting pump for a riverbank itself won’t have to travel once it is installed. Even as a backup ‘secondary’ pump, such as a backup to a primary rainwater supply, it will remain installed and ready to use when required. A ‘portable’ fire fighting pump is used though because these portable ones are very affordable and a single-unit that can be installed much easier than other kinds of permanent pumps, and their location can be adjusted if need be. The water that it is pumping however from the river to a homeland or central place in a community would travel a distance of 20+ metres if this is what you are asking.
Hope that helps but feel free to ask another question here to clarify,
Best of luck,
