Drainage Rodding Points
When designing an underground drainage system you should be sure to allow suitable locations that can be used to clear any blockages and allow access for maintenance if required.
There are a few different options when it comes to accessing the underground pipes. Firstly we have pipe bends with screw caps built into them to allow rodding to be done through them. With the use of a few different parts you can create as the above diagram shows. A hopper, gully trap and 87.5° access bend all fit together.
Rodding points are normally installed in storm water drainage systems. And should be situated no more than 22m away from an inspection chamber. The rodding point needs to be laid into a slab on concrete to support it and ensure it doesn’t become mislaid at ground level.
