What irrigation is best for a small slope
I would like some help on irrigating my sloped hill. I currently am running a rain bird irrigation system. The following is the criteria that I have:
Rain bird ESP controller with 6 valves
Avg 40 #PSI
10 gal per min flow.
Slope is 6’6” with a 2’1” drop, soil is silty clay and length of run is 80’.
My landscape plan will incorporate shrubs, ground cover,and possibly some flower beds.
Some opinions state to run a ½” emitter tubing with a minimal of 18” spacing of the emitters. Others have noted a solid ½” tubing with emitters strategically placed near the plantings. Lastly I have read of running 3/4" or 1" pvc pipe the length of the slope and have mufti-emitter manifolds on risers with ¼” tubing distributing water to the plants. On the other hand it has been noted that 1/4” is not the way to go due to problems.
I have thought about upgrading the controller to the ESP-SMT to give me more control of the timing of water distribution on the slope.
Questions: What is the best way to build the drip system or there a better way? Should I scratch the
drip system idea and go with a sprinkler setup? What valve, pressure relief valve, and filter is best?
Any help would be grateful.
