You disconnect it from the black tank, and run water in one end while the other end is still down the opening at the dump station. Most dump stations have a water source, usually labeled "Non-potable," with a hose already attached. Often the hose will be lacking a male fitting on the free end, so that it's not even possible to connect it to your municipal inlet.
Don't forget to rinse the outside of the hose as well; and hose down the area around the dump station drain to wash any residue that ended up on the pavement instead of down the drain.
