I do not know, but I have an old stone duck, I want to build a concrete pool (wide but shallow) for geese and install it there, and connect the water to the duck so that it spits this water into the pool. It is true that this duck has yet to be restored, it is necessary to wipe the cracks with a solution of cement and paint it all. A cheap stone duck, I bought it once upon a time in the market.
Previously, it stood near a small fountain (about 15 years ago), but then this fountain had to be removed. I want to restore, but make a big one for geese, in the place where are my geese. And on the side I'll make a drain pipe with a tap, so that i will can drain the dirty water and pour a new one (dirty water i want to use for the greenhouse). The project is simple - to bring a drain from a large greenhouse (for rainwater to be poured in), and from shed (I led the water from the well to the shed).
