With our Source Data tool, you can quickly configure and place the water source for your irrigation project.

Source Data Overview
The Source Data tool is available from the Irrigation Manager for your project.
Open the Irrigation Manager:
F/X Irrigation ribbon, Irrigation button
F/X Irrigation menu, Irrigation Manager option
Irrigation Manager toolbar
or type ProjectIrrigation in the Command line
Click the Source Data button in the Irrigation Manager to open our Source Data tool.
1. Point of Connection (POC) Number: You can have up to 99 different points of connection (POCs) on any one project. Click the New and Delete buttons as necessary to control the POCs you add.
2. Water Meter Size: Select this option if your project will include a water meter. Determine the water meter size for your POC. and the factors that will affect it, and enter this information in the menus and fields provided in this section. (This information is discussed in detail below.)
3. Point of Connection Size: Select this option if your project will include a source that a large water main can be tapped into but that will have no water meter (such as on a large government facility or in a rural situation). Use the pull-down menu to enter the size of the POC.
4. Custom Max Available: Enter a custom flow and pressure for your source, and add any necessary notes.
5. Flow Available: Based on the information you enter and select above, this box will indicate the flow available for that situation.
6. Static Pressure at Service: Enter the static pressure you anticipate at the mainline service for your project.
7. Pressure (PSI or bars) Available: The final pressure anticipated at your POC based on the factors entered above.
8. Water Source Information: This optional text field allows you to indicate where you received your information on the water service. You can enter this line into the irrigation schedule.
9. Set Detail: Clicking this button will set a detail for this water service, if required. If set, the detail will be added to the project's Detail Manager and will be indicated for the POC in the irrigation schedule.
Water Meter ("Water Meter Size" Option)
Water meters are the most common type of source in many locations. The Source Data includes several features pertaining to the flow that will be available for a specific water meter size.
1. Select the Water Meter Size option.
2. Use this menu to select a size for the water meter.
3. Select the Safe Flow you wish to represent through the meter using this slider.
4. Select a Service Line Size using this menu.
5. Elevation Change from Service: Enter the elevation change from the meter to the water main in the street, or estimate what you think it is.
6. Select the type of Service Line Pipe Category from this menu.
7. Service Line Flow Velocity: Use this slider to select the maximum velocity for the service line in the street.
8. Available Flow: This figure will reflect the changes you make to the information above, as different meter sizes, pipe types, service line sizes, velocity, etc., will create differences in the available flow.
The goal of selecting a certain water meter and related pipe and velocity is to maximize the flow available to your source: the water meter. The flow should reflect the needs of your project, and little more. Efficiency is the key. This means avoiding having a source that is too small for an adequate water window, or too large with a substantial cost that imposes an unneeded cost burden on the client. Always keep your eye on the last item, GPM (or l/min) Available. Tinker with the limitations for a meter to maximize your output.
For Turbometers, or any case where the desired meter falls outside the bounds of our Source Data dialog box parameters, you will need to establish the meter as a Custom POC
Safe flow is the percentage of the flow for which a meter was designed.
A 75% safe flow is considered normal. However, if the agency has a specific requirement, you should respect that requirement.
We have seen between 50 and 85% safe flow required by agencies, but if no one is sure, 75% is a normal figure.
Service Line Size
The service line is the line leading from the water main in the street to the water meter (see image below).
Select a Service Line Size from the menu.
On an existing system, look at the pipe that is connected in the street to your meter.
On a new system, you might be able to specify a service line of your choice.
Thus, it's logical to make the service line size one or two pipe diameters larger than the meter size itself so the service line does not become the limiting factor.
Elevation Change from Service
Elevating water from the water main in the street to your meter will require some pressure.
In the field shown to the right, enter the length of service line in the street to the meter, to allow for loss through that pipe.
Service Line Pipe Category
Select a pipe category for your site's service line from the menu shown to the right.
Your service line might be a polyethylene, copper, PVC, or galvanized pipe. The type of pipe will affect how much flow is available through it.
Service Line Flow Velocity
Select a flow velocity for your site's service line from the menu shown to the right.
The Service Line Flow Velocity is only for the service line in the street – not for any piping within your project.
This velocity might be considerably higher than you would accept for your project piping, but this is acceptable to achieve the maximum flow possible out of your meter size.
Large Water Main, No Water Meter ("Point of Connection Size" Option)
Select the Point of Connection Size option if your project will be tapping into a large water main but will not include a water meter.
Select the size of your POC from the menu shown to the right.
Custom Water Source ("Custom Max Available" Option)
The Custom Max Available option allows you to enter your water source's flow and pressure manually, as well as add notes about the source. Even if you know the size of your POC, it's often best to use this custom option.
This type of source will usually be:
- A well and pump situation, such as on a rural, agriculture, or park facility
- Any water meter whose requirements fall outside of the typical Source Data parameters, such as a turbometer
Placing Your Water Source
Once you've configured your water source, you can place it in your drawing.
Click in your drawing where you want to place the water source.
Once you've configured your water source, you can also place it using our Place Equipment tool.
Placing a Water Meter
If you selected the Water Meter option, the following dialog box will prompt you to set a number for the water meter.
You can also leave the default M for "meter."
The characters you type in this dialog box will appear within the meter symbol in your drawing.
Important: This text is limited to either 7 or 10 characters, depending on your installation. Do not exceed this character limit, or you will create problems in your Irrigation Schedule. If you need to give your water meter a detailed description, use one of our text leader tools to call it out.
Placing a Point of Connection (POC) (Such as a Well)
If you selected the POC Size option, you'll be prompted to enter a Point of Connection #.
Important: This text is limited to either 7 or 10 characters, depending on your installation. Do not exceed this character limit, or you will create problems in your Irrigation Schedule. If you need to give your POC a detailed description, use one of our text leader tools to call it out.
The symbol pictured to the left will represent the POC in your drawing.
Accounting for Multiple Water Sources
Some irrigation system designs will require you to account for more than one water source. For example, a site might draw water from two or more water meters or wells that you need to tie into your system.
For information on designing sites with multiple water sources, see our Accounting for Multiple Water Sources documentation page.
Setting Up Your Pipe DataNow that you've set up your water source data, it's a good idea to also set up your pipe classes before you begin designing. See our Pipe Data page for instructions.
