Phoenix Golf Club 2nd fairway drainage project It's a tad damp ☔️

Click for quick video

Now that's what I call wet!! Unfortunately being our 2nd fairway when the conditions become too wet to play, due to our course layout it screws up the chance of playing 9 holes so something had to be done..... We know the first thing you do when designing a drainage scheme is to identify where the water is going to go once you've collected it (and where its from! more on this later), luckily we had a nearby culvert to discharge into however that was far too simple.... Our inlet was lower than the outlet of the culvert, not good for flow! So a little poetic licence was required and a sprinkle of jiggery pokery.

Old drainage in orange and "fall" in yellow

ok remember the 2nd thing about drainage, where's the water coming from? remember this is just a theory..... during our trenching activities we trenched through about 4-5 old drainage lines indicated by the orange dots, the orange lines are where the old agricultural drain lines are possibly running, the yellow lines indicate "fall" or elevation decline. there is a 10 meter elevation difference between the 4th green and the 2nd drainage, now here's the theory........we have 3 sources of water on the 2nd fairway, the 1st being the most obvious "rainfall" which is falling directly on the fairway, 2nd being surface transported water i.e. water following the yellow arrows and flowing down hill onto the fairway and the 3rd source........this is where the theory comes in, speaking to several eminent members they have noticed over the years (20 to 30) a gradual decline in surface drainage on the 2nd fairway, it is my theory that the trees planted to the right of the fairway have been blocking the old agricultural drain lines with their roots and slowing the flow of water over time until a total blockage of the old system has occurred, this would account for a gradual decline. Now remember the elevation difference between the 4th green and the 2nd drainage scheme (10mts) this represents a lot of water "head" if the old drains are totally blocked the hydraulic pressure will force the water to the surface, we had a similar situation on the 11th where I was told about "springs" that had surfaced which were actually old agricultural drains that had been destroyed by newer drainage attempts. lets dig...........................................

Below is a diagram of the basic layout of the 2nd scheme.

This water was collected in 1 hour it represents 13 mm which fell on the 2nd approach, not too shabby

We had a few problems but no big deal

I would like to thank all the Artisans and Greenkeepers for their fantastic efforts during this project, work was completed on the 19th September 2016..........just hope it works 😉 Thank you, Graham Pickin
