Boat Septic Pump Out?
I am very familiar with dumping septic holding tanks in a camper on land. I do it regularly and safely, either at the camp ground or at home.
I am considering a boat trip on the Ohio and Mississippi rivers, which would involve purchasing a boat with a head/toilet. All I know is that is illegal (and immoral) in most cases to dump septic in the river.
What is involved in emptying septic holding tanks from a boat, on major US rivers?
What are the normal fees?
How do I find the appropriate facilities?
I have used portable toilets in campers, I know they can also be used in boats. I am interested in the 'how to' of the integrated type that uses a holding tank integral to the boat.
