Small Farm Drip Irrigation

Step 1: Gather Information
1. How far is my water source to the last row that I need to water?
This will help you find how much mainline/header row tubing will be needed. You will need to measure from your water source to your rows. Then you will need to measure the distance from your first row to the last. This distance will be your header row, which is where you will run your lateral rows of drip tape down each row. When you add the tubing required to reach your plot from your water source and the length of your header row you will get the total amount of mainline tubing needed.

2. How many rows do I intend to water?
The number of rows correlates to the number of fittings that you will need. Each row will need a tape take-off valve and a tape end cap.

3. How long is each row?
This will help determine the total amount of drip tape that you will need. Add up the length of each row. For example: The max run length for drip tape with a 0.25 GPH emitter is 606 ft. at a 0% grade with a 90% uniformity.

Step 2: Creating a sketch
We recommend creating a sketch of your project area. We have found that a sketch helps to visualize the area and ensures that you have not overlooked any details.
