Storage channel
Sewer structures of drainage systems are referred to as storage sewers , in which the water arriving during heavy rainfall is initially dammed and only discharged into the subsequent sewer system in a throttled manner . A storage channel is thus a collecting channel with a larger cross section.
background
In the planning process, worksheet DWA-A 117 - Dimensioning of rain retention areas applies to the dimensioning of storage channels . However, there are no precise specifications about the size and the duration of the memory drain. The figures to be used come from statistical evaluations and long-term simulations.
Construction methods
There are essentially two different construction methods for a storage duct:
- Rain overflow storage sewer: Here, similar to the rain overflow basin, the collected volume is diverted into a connected body of water. In the last step before the transfer into the water, the volume is prepared.
- Rain retention storage channel: Here the volume is simply retained. There is no discharge into a body of water.
