How to use Drip irrigation runtime calculator
  1. Enter your measured quantities, units and assumptions.
  2. Review the calculated result and the stated limits.
  3. Download the report or plan for your project.

Useful next steps

Use the flow for your emitters

Enter emitters per plant, their nominal flow and the water you want to reach each plant. The application efficiency accounts for your assumed losses. No crop-specific watering target is selected.

Compare zone schedules

Plants are divided as evenly as whole numbers allow. Run zones sequentially or together and compare their peak nominal demand with the supply flow you enter. A flow comparison does not validate pressure or soil absorption.

Save the measurements and assumptions

Download CSV and a text or JSON report. The calculation runs on your device. Changing a unit keeps the number you entered, so check both before using the result.
