A sub-column is a device for the proportional distribution of the water of a source on the basis of the water rights to several consumers. They are particularly widespread in the Alpine region.

The device consists of a standpipe about two, in rare cases up to five meters high, through which water is supplied from a source , usually two to four outgoing pipes and a pot that can be closed with a lid. The lower part of the pot contains several chambers of equal height to which the outgoing pipes are connected. The height of the pot is chosen so that the incoming water overflows from the mouth of the inlet and is evenly distributed over all individual chambers. Any amount of water can be taken from each chamber if there is sufficient water supply. As soon as the water consumption exceeds the inflow, each consumer can only take off as much as overflows into his chamber. If a consumer does not consume water, his chamber fills completely and then overflows into the other chambers.

Part columns are often found in public drinking troughs in the local area where they make sure that the feed is continuously supplied. Some of the pillars are protected against frost by board cladding. After a long period of use, the pillars can become encrusted to the extent that they look like a mossy limestone rock due to calcareous sinter , which is precipitated from overflowing water. However, they are mostly still functional because of their simple design and large pipe cross-sections.
