Winterizing Golf Course Irrigation Systems

As the temperature drops and winter approaches, winterizing your golf course irrigation systems becomes crucial. Proper winterization prevents damage from freezing temperatures while maintaining the system's longevity. This ensures a smooth transition back to operation in the springtime. Water left in pipes can freeze, causing pipes to expand, leading to significant damage. Cracked pipes, broken sprinklers, and faulty valves can lead to costly repairs and delay spring operations. Winterizing safeguards against these issues and ensures your irrigation systems are ready for spring.

Preparing For Winterization

The best time to start winterizing is in the fall, ideally before the temperature drops to freezing. Monitor weather forecasts and climate patterns to determine the best time to start. Inspect your systems and make any repairs before winterizing. Collect the necessary equipment to complete the process. For golf course irrigation systems, an air compressor with at least 600-1200 cubic feet per minute is recommended. Also, make sure you have access to insulation beforehand to guarantee you can complete the job. Backflow blankets can also be used to further insulate and protect your irrigation systems. 

Steps for Effective Winterization

After collecting your equipment, you can begin the winterization process. shut off and winterize your pump station. After this, drain all water from the main lines using either manual or automatic drain valves.

The next step is to empty the system by using compressed air to blow out any remaining water. Check to make sure all the other drain valves are closed, except for the valve where the air hose will attach. After hooking up the hose, allow the air compressor to charge. When blowing out the irrigation system, it is recommended you use no more than 50 psi. Blowing out a system with too much pressure can cause damage. It helps to start at the station with the highest elevation and work your way down. You will know that your station is complete when the sprinkler heads stop releasing water, however, it is better to run two short cycles rather than one long one. Not only does this reduce the risk of damage to the system but it allows you to double check and make sure no station is missing.

Protect above-ground components like backflow preventers and valves by insulating them. This added layer can prevent freeze damage. Open all the drains and leave them open at a 45-degree angle. This step prevents damage from condensation. Finally, make sure the pumping station is heated or is fully drained of water and properly shut down for the cold winter months. 

Golf courses have specific needs due to their extensive turf areas, special features and quantity of sprinklers. Making sure your team is properly trained, and you have proper equipment is essential for taking care of these systems. Keeping a record of the process and dates of any repairs is important for future reference if troubleshooting is needed. By being proactive, you can maintain the playability of the course. 

Post Winterization Checklist

After completing the winterization process, double-check and ensure there are no remaining exposed components. As the temperature warms up remove any insulation or protective coverings and inspect for any signs of damage that might have occurred during the winter. When recharging the irrigation system, open multiple discharge points and repressurize slowly to evacuate entrapped air. Once repressurized, test all components for proper operation and make any needed repairs or adjustments. Be sure to test each irrigation station to ensure it operates correctly and adjust sprinkler heads and valves. It is crucial to be thorough during this process to prevent costly damage and to welcome golfers with a pristine course.
