To my knowledge, the cost I mentioned is for just a turbine/generator unit. It's what you'd pay if you could walk down to a Home Depot and, well, "pick one up". Any transmission infrastructure is an additional cost.
This would obviously need a holding tank of some sort, but in the areas water is really scarce in practice, people don't so much care about getting it delivered to their home. This could be the equivalent of going to a well or stream to fill some containers.
