Your setup looks good, I have outside my buckets and waterers across the yard from my feed bowls and my ducks get a mouth ful of food and walk all the way to the water to eat it. Their just messy so expect to find food in the water and vice versa.
Rich386, a nipple watering system will not work for ducklings and ducks/ geese they need deep water to wash out their nares and eyes. Your system will work great from other poultry but not waterfowl.
