A standpipe is the connection between the downpipe and the sewage system

A standpipe connects a rain downpipe to the sewer pipe. It usually consists of a sturdy material and protrudes half a meter to one meter from the ground. Preferably, the downcomer should have an overflow and an inspection opening.

Stanchions made of resistant material

In the event of a backwater or a clogging of the sewage system, an excessive water pressure may occur. Standpipes should be made of a material that can withstand the stresses.

If the standpipe is protected, a height of half a meter is sufficient. If it is open, it should be extended to a height of 1.50 meters. To prevent it from cracking during overpressure, it is advisable to install an overflow.

Inspection opening and rain collector

The openings of the overflow are often also integrated into an inspection opening. This is required if the standpipe is difficult to reach. If dirt is to be expected due to leaves, then a leaf collector can also be installed above the standpipe.

If you want to collect rainwater that you want to use for casting, you can install a rain collector directly on the standpipe, ideally below the downpipe strainer.
