Golf Course Irrigation

Sep 11, 2015
Video Length:  1:04:50
Presented By:  Jake Lott

Golf course irrigation is a design skill in and of itself. In this webinar, we'll demonstrate some of the great tools Land F/X offers to help ensure proper mainline sizing and scheduling. We'll also discuss some of the key points to remember when using flow zones, shut-off valves, and valve-in-head rotors. While this webinar will not cover the theory behind golf course irrigation design, it will provide a detailed look at the Land F/X tools that pertain to golf course irrigation.

6:36 – 16:34: Understanding And Using the Right Equipment

Valve-in-Head (VIH) Rotors (7:40)

Selecting a specific VIH rotor model (7:40)


Shut-Off Valves (9:30)

Note: Shut-off valves are crucial to golf course irrigation because they allow portions of the system to be shut off during maintenance.


Central Control System (Controller) (10:40)

Adding a central controller (10:40)


Joint Restraints (11:25)

Adding joint restraints (11:25)


Overview of the different types of available joint restraints (11:30)


Placing the Equipment (13:20)

Placing shut-off valves (13:20)


Note: The computer won’t know your exact design intentions. It simply feels along the mainline and lateral line pipe, looks for different types of equipment, and calculates accordingly. (14:30)

16:35 – 23:09: Flow Zones

Accessing the Flow Zones feature from the Size Mainline tool and selecting a new Flow Zone (16:40)


Entering a Maximum Multi-valve Flow (17:00)

Note: Flow Zones don’t add flow – they only limit flow. And a Zone only limits flow if the given flow in an area exceeds the maximum flow that’s set for the zone.


Double-clicking a flow callout number to change its value (20:30)


Using the Highlight Station tool to show the contents of a Flow Zone (22:30)

23:10 – 38:59: Mainline vs. Lateral Line

Placing a few heads (23:10)


Hooking the heads together using Lateral Line (the system will treat the pipe like mainline) (25:25)


Placing shut-off (gate) valves (26:20)


Piping to the gate valves with mainline and connecting to the heads (26:40)


Using Highlight Station to highlight the zone. Note that it will only highlight up to the shut-off valves if you select a zone, or highlight the system but not the zones if you select the pipe outside the zones. (27:20)


Placing Flow Zones and setting a maximum flow for each zone (27:52)


Placing Schematic Irrigation zones (29:30)



Placing a cap to simulate a flow zone (30:30)


Using Highlight Station to determine the flow of a given area (31:45)


Placing the cap (32:15)


Placing an isolation valve and piping to it from the cap (32:40)


Placing additional caps and copying/pasting them (before piping to them) (33:30)


Piping to the caps (34:15)


Note: Lateral pipe can’t usually handle quick coupler valves. However, in the system we’ve set up, the lateral line behaves like mainline and can therefore handle quick coupler valves. (34:40)


Using Match Properties and drawing a window across the entire plan to open and close isolation valves (36:10)

39:00 – 56:19: Spot Elevations & Pipe Sizing

Note: When you have Land F/X Spot Elevations placed throughout your site, the system will assign each component to the nearest Spot Elevation. For this reason, we recommend placing Spot Elevations generously throughout the site. (39:00)


Using the Verify Mainline tool to ensure that all components are connected to a water source and that all valves are called out (41:30)


Using the Valve Callout tool to label valve-in-head rotors (note that you can click your Valve Callouts to renumber them incrementally). (41:30)


Sizing the mainline and using Spot Elevations for valve elevations (44:30)


Question: Can Spot Elevations be in an Xref? (48:05)

Answer: Great idea. We’ll look into adding a toggle offering an option to place them in an Xref.


Note: You can use the NCOPY command to create boundaries and areas in Xefs – it recognizes polylines in Xrefs. (50:30)


Checking the Critical Analysis (52:25)


Checking the tees with View Data (53:29)

56:20 – end: Scheduling Options

The Irrigation Schedule (56:25)


The Valve Schedule (pinpoints troubleshooting issues such as unknown valves or wire lengths). Note that the schedule also recognizes the closest controller. (57:05)


The Runtime Schedule (allows you to determine a runtime based on the amount of watering you need per day or week) (58:50)
