We are on a septic system, so down the drain is a definite no-no. I dilute it 1:4 with water for fertilizing the garden and about 1:10 for houseplants. The chickens love it, especially in the winter, when we have to put it in a heated dog dish to keep it from freezing before they can drink it all. Piggies get it while they are here, usually May through November. When I get too much to feed to my animals, I send some to the neighbor that raises pigs.
