Overflow Log

The add-on is used to record and log backwater and discharge events as well as discharged water volumes at stormwater overflow basins. Monthly and annual reports can be generated as PDF or TSV files. The add-on requires the water level in the stormwater overflow basin in order to recognise backwater and discharge events. This must be provided by the site to which the add-on has been added in the form of a measuring channel. Discharged water quantities (also known as discharge quantities) can be calculated separately for sewage overflow and basin overflow. The following methods can be chosen for the calculation

• based on the water level using the Poleni formula
• based on the water level using a reference table
• based on any measurement channel provided by the site using a reference table
