Sub Surface Turf Irrigation Drip Zone Planning 2
Drip Zone Planning For Sub Surface Drip Irrigation Systems
Now that we have gone over the basics for Drip Emitter Tubing and Flow rates we will apply this to a sample sub surface drip system. For this example we will assume the following:
The illustration below will serve as our sample property for the installation of the sub surface system.
We will now illustrate our Drip Line layout ove our property sketch to calculate our Drip Line requirements and Water Requirements for the system.
At this point we can see that if we are using a .42 gph emitter flow rate we will not be able to water the entire system at one time and will need to split the sytem into two zones as our water available is 240 gph and we need 271. That being said we always recommend to be conservative with water estimates and never plan for more than 75% of water available, which would make our available flow 203.4 gph (271.2 x 75%).
We will now continue with our 2 zone assumption to illustrate the system, however the connections and layout are virtually identical to that of a one zone system if our assumptions had changed.
