and I'm doing to put in drip irrigation. Trees growing too slowly for my liking.
Fliptop, I installed my drip irrigation system recently and am ecstatic with the results. I'm irrigating an acre of trees with 112 drops on one zone with plenty of water volume available to add additional future drops for the nursery.
If it helps, I'll share the details on my setup... My well produces 12 GPM, so that is the starting point.
The property has a 30" elevation from lowest to highest at the emitter locations, so I decided on pressure-compensating emitters to account for elevation loss and gain. I chose 2 GPH emitters after doing the math using 112 emitters in total. I wanted to have some reserve.
112 Emitters x 2 GPH = 224 GPH ÷ 60 Minutes ≈ 4 GPM consumed by drip system. Even with the math, I was skeptical and thought this configuration would result in a substantial loss requiring splitting this system up into several more zones. I stuck with my gut based on these calculations and remained committed to maintaining one zone.
For the black poly tubing, I chose Dig .710" and went with their termination fittings having the blue rings (.710" fittings). The female hose (FHT) connectors each have an inlet screen fine enough to keep sediment from getting in and plugging up the drip emitters. I also picked emitters that could be unscrewed and manually cleaned as well. Each poly pipe run is terminated with a cap to allow for flushing and future service.
My distribution piping throughout the property (undergound) is all 1" PVC from a 1" zone valve, and the header risers are 3/4" PVC. I used 3/4" PVC ball valves and Male Garden Hose Thread (MHT) adapters to allow full flow to the poly tubing. Each poly tubing feeder attaches just like it's a garden hose.
Drip emitter assy's were made from 1/4" distribution tubing cut into 2' sections with a 2 GPH emitter on one end and a 1/4" barbed connector on the other.
Putting it all together and digging trenches (even with a rented trencher) was a chore and not fun. Used 1,500' total black pipe and roughly 1,500' of underground PVC. I'm glad that job is done, lol.
The irrigation controller is a WiFi type so I can essentially control it remotely from my phone in the field for testing, etc.... Turning it all on for the first time after purging the lines and capping the ends, I was very happy with the results. All emitters produce 2 GPH, and I still have 48 psi of pressure... Plenty of pressure for additional taps in the future as I mentioned earlier.
My trees are on every 3rd day schedule for 1 hour. Drink up, baby trees, drink up and grow!.
