Abstract: Modern bunkers with lush green faces are required on many modernized golf courses. They replace weathered bunkers with dessicated faces. Insure proper maintenance with bunker irrigation.
Pictures of windswept Scottish links show browned bunker faces with fescues blowing in the wind. It’s a nice aesthetic component, but many golf course owners and members want vibrant turf lining surrounding bunkers. Install bunker irrigation to insure healthy green turf.
Some golf courses irrigate bunker faces with overspray from adjoining fairway and rough sprinklers. This works if you have subtle bunker forms with short bunker faces. If you have deep and steep bunker faces, you’ll need to install individual bunker zones.
I use individual spray zones to irrigate bunker surrounds. Let’s assume you have a modern decoder irrigation system. Install an electric valve or two and connect to the decoder network. Install 1″ or 1 1/2″ HDPE pipe that bends with the bunker contour. Center spray heads to insure equal distribution. Simple and effective, this installation costs around $1500.00 per bunker in the Northeast.
Golf courses with limited controller options can use individually battery powered valves. Plumb into existing, pressurized mainlines. Nine-volt battery powered valves feature timing controls and independent operation. The batteries last about a month.
I’ve seen bunker faces with drip irrigation installed. I don’t like the coverage and inability to syringe surrounding turf and sand.
