How can I find the total volume of water in my network?
To see the total pipe volume in WaterCAD, WaterGEMS or HAMMER, click the Report menu and choose Pressure Pipe Inventory. This will show you the total physical volume of all pipes in the model, broken down by diameter and material. Since pipes are assumed to be pressurized, this also represents the total water volume stored in your network.Note:
1) You will need to account for tank volume separately. See the "Volume Full (Calculated)" or "Volume (Calculated)" fields in your tank(s).
2) If you need to see the total volume of water that has passed through a particular element, you should instead use the Totalizing Flow Meter, accessible from right clicking on the element, or from the Analysis menu.
3) If you need to see the total volume of water demanded during a simulation, see the below related wiki solution:
In our storm and sewer products, in order to find the total volume of all pipes (some may refer to this as the capacity) you'll first need to find the total volume of each pipe. You can do this by creating a formula based user data extension (UDX). If you only have circular pipes, the forumula would be Pi * (diameter * 0.5)^2. For box, it would be Rise * Span. If you have a mix, you can use the "iif" function.
Once done, you can add up the volume of all pipes either by copy/pasting the column from a flextable into an Excel spreadsheet, or by adding the newly created UDX field to the flextable then right clicking on the column header and choosing statistics. The directions in the article below outline how to create a formula UDX:
Creating Formula Based User Data Extensions
1) You will need to account for the volume of wetwells, ponds, manholes, etc separately. See the "Volume Full (Input)" for a wetwell. Manhole volume can be calculated with a user data extension as well, based on the difference between the invert and rim and the diameter.
2) For pressure pipes, the volume can be found under Report > Conduit and Pressure Pipe Inventory > Pressure Pipe Inventory.
3) If you need to see the total volume of water that has passed through a particular element, you can use the Hydraulic Reviewer, located under the Tools menu.
