Importing Water Valves Shape file into WaterGEMS

Hello Jason,

By "water valves" do you mean these are different valves like Pressure Reducing Valves (PRV's), Flow Control Valves (FCV's) etc. or valves like Air Valves (AV's)?

Ideally, each type of different valve should have its own shapefile. That way you can import them as different element types in WaterGEMS. However, if they are all in a single shapefile, you can select one type and then batch morph them into other types.

Another option is to use the same shapefile for different element types. This can be done by duplicating the shapefile in ModelBuilder and then using the "WHERE" clause to filter specific elements belonging to a particular element type. See the below wiki for this for more details on how you can do this;

Using the WHERE clause and Duplicate option in ModelBuilder to filter imported data

If I try to import the Table Type as "Valve with Linear Change", I don't get duplicate; but get error message "Downstream Pipe is Unidentified."

Elements such as valves and pumps are modeled as nodes in WaterGEMS but act as a "link" because there is change in hydraulic grade through them. For such elements, the direction in which they are oriented is important, hence you have to specify the downstream pipe for such elements. This enables the program to model the element with the correct orientation. For example, a Flow Control Valve (FCV) can control the downstream flow only and for that purpose you need to define the direction of the valve by specifying the downstream pipe.

You can add this attribute in the shapefile for your valve elements.
