I don’t know if this counts. I recently purchased one of those 275 gallon, IBC totes. When I do my water changes, all of my dirty water goes into a trash can. From there it is pumped out of the house to the tote. The tote is on blocks so that the bottom is higher than my raised garden beds. When ever I need to water the garden, just open the valve and gravity pulls the water. Best garden I ever had!!!
