The intake tube is relatively easy. As stated above, it helps to have a form around which to make the bend. A steel spring inside the tube will help prevent kinks. It also helps to be able to cool the tube fairly quickly so that it stays in shape.

But the output 'S' shapes tube would be more difficult to form.

Some expandable cafe curtain rods have springs inside - open the ends and remove...

Have you also made the out-flow pipe too?

In NYC we have some excellent plastics dealers on Canal Street. They stock and sell acrylic / plexiglas in sheets and tubes of all sizes. But that is not going to be of much help to you in Geneva, is it?

Try to make a flare at the end of the pipe, similar to ADA Lily pipes. The flare helps to distribute the outflow around the tank.
