Main layer for manholes, special structures, infiltration installations, discharge points (and wastewater treatment plant (wwtp) structure). Creating a new record in this layer always creates a new wastewater structure, a new cover and a new wastewater node. In the edit form, you have access to a lot of the related tables (e.g. structure parts, maintenance events).
Even if there are several covers or wastewater nodes, there is just one point for every wastewater structure in this layer. By default, the position of the wastewater node created first is used as the point coordinate.
Atenție
Do not export this point coordinates as covers. Use the layer vw_cover for this.
Main layer for line-wastewater structures (channels). Creating a new record in this layer always creates a new reach and a new channel. In the edit form, you have access to a lot of the related tables (e.g. structure parts, maintenance events).
This layer shows and enables you to edit the detailed geometries of wastewater structures. You can add a new detailed geometry using the layer vw_qgep_wastewater_structure action called digitize detailed geometry.
3.1.2.2.2. Structure Parts qgep_od.structure_part
Cover is the only structure part with a point-geometry itself. All other structure parts are just linked to their wastewater structures and should by only edited by the main layers (vw_qgep_wastewater_structure and vw_qgep_reach).
Use this layer to change the situation of some specific cover (and not the whole wastewater structure) or to add a new cover to an existing wastewater structure. You can add an additional covers in the covers-tab of the vw_qgep_wastewater_structure too. Additionally, use this layer to show the detailed position of the covers (e.g. in network_plan or pipeline_registry) or to export the cover positions situation_geometry.
od_organisation contains the organisation that you can select in attributes like fk_dataowner, fk_operator, fk_provider, fk_owner, etc.
This table is today a little bit hidden in the wastewater_structures group (but it is not only related to wastewater structures).
If you want to export data to the VSA-DSS 2015 model, you have to manually add the relation to the respecitve subclasses of organisation by adding the respective obj_id’s in the subclass tables, e.g. municipality, else the export will give an error message. For export to SIA405_Abwasser and VSA-KEK this is not needed.
Alternative: You can use vw_organisation instead of od_organisation. vw_organisation has the subclasses integrated and must be loaded manually to the project.
Use this layer to change the situation of one selected wastewater node (and not the whole wastewater structure) or if you want to add a new wastewater node to an existing wastewater structure. You can add additional wastewater nodes in the wastewater nodes-tab of the vw_qgep_wastewater_structure too.
3.1.2.6.1. Nodes qgep_network.node and segments qgep_network.segment
These two layers are used by the qgep-extension for the profile and the network-following functionalities.
Use the qgep_network.segment layer to show the flow direction, if you use a markerline (filled_arrowhead) as symbol.
