	A WFPS can be installed within months rather than years and it is considerably less costly than comparable traditional fish ladders such as vertical slot passes. Given that the WFPS componentry has been designed to be modular, systems can be configured for varying species, entry situations and river conditions, all using standardized componentry. Expensive customization is thus avoided. WFPS systems can be land-based but also include floating options, so that complicated design/build and permitting may be streamlined. Since only negligible flows of water are used for the operation, it may even pay for itself in situations where no environmental flows must be released, e.g. in hydropower dams where the power house is at the bottom of the dam, or in situations where a ladder exists and is now no longer needed – the hydropower value of the extra waterpower realized can often more than cover the cost of the system.
