NETWORK FOLLOWER

The Network follower tool can be found in the KeyAqua tools. This function lets you follow a water and sewer network, its connections, and elevation data (in sewage and rainwater networks). Network following requires ducts and nodes to be connected to each other in KeyAqua. On the form, use route options to specify the direction of following and whether the network will be followed across open valves or not.

Route options: Continue over open valves

Following will continue over the valve if its status is not Closed. The network will be followed across the open valves for as long as possible.

Route options: Stop on valve

Following will end at the first valve that is found. When following in both directions, following will end at the first valve found in each direction. The network section between the valves will be highlighted on the map.

Show closed valves in the list window (for water):

When network following ends, a list of all closed valves for which following ended will be displayed.

Use z-coordinate (for sewer):

The network will be followed downhill using the duct route and in accordance with the sewer duct’s z-coordinates. This option is not available for water ducts.

Use flow direction (for sewer and pressure sewer):

The network will be followed downhill along a sewer or pressure sewer duct in accordance with the flow direction settings. The flow direction for ducts can be defined to be different from the elevation-based flow direction.

Network following is started from either a node or a duct. The network object from which following will be started is selected with the Network follower function. Select the duct or valve you want by defining an area on the map with the left mouse button. A list of the found objects will be displayed. To start following, place the mouser cursor on the selected object, click the right mouse button, and select Start the network follower. The network will then be followed in both directions. If you select a water duct, you can indicate the direction in which the network will be followed on the map. To do this, click Point direction and start the network follower. The followed network will be highlighted on the map. To stop following, click Remove map layer or close the Network follower form.

For water ducts, you can either choose to follow in both directions or indicate the direction in which the network will be followed.

The results for network following can be listed or shown in a group display, through which you can, for example, select the consumer points affected by an interruption in water supply and send an SMS to the customers. To use these functions, click List  or its drop-down menu.
