Connect Catchment area to Wastewater Network Nodes
You connect catchment areas with the tool **Connect wastewater networkelements** (it's the same tool to connect reaches and nodes described in the chapter Editing in QGEP).
* The **catchment_area** layer has to be in edit mode
96
+
* Click the **Connect wastewater networkelements** button
97
+
* If you move the mouse over an catchment area near the border of the catchment area, it is marked: you can click to choose this record
98
+
* Move the mouse to the networkelement, to which the catchment area will by connected (again: selectable objects get marked) and click again

109
+
110
+
.. note:: In the VSA-DSS-Datamodel, it is possible to connect catchment_areas to wastewater nodes or to reaches. Because a lot of hydraulic calculation do not support connections to reaches, this tool in qgep connects only to wastewater nodes and not to reaches.
111
+
112
+
.. note:: The tool does not check, if your choosen wastewater node is a part of the pwwf-network (primary network). It's only the user who deciedes, if a node is ok or not. If you are not sure, please check the **VSA Wegleitung GEP-Daten**, part **Erfassungsgrundsätze**
113
+
114
+
You can not connect multiple areas with the tool to a wastewater node at once. If you want to do so, you have to select the catchment areas, open the attribute table and then start the multi edit mode. There you can choose the wastewater node from the list of all nodes
115

Do delete a connection to a wastewater node, you can edit the area with the **Identify features** tool.
