Drip Irrigation Flow Calculator
Size a drip system and set a timer that delivers the water your plants actually need. Enter the number of emitters on the zone and the rated flow of each in gallons per hour, and the calculator totals the system flow in gallons per hour and per minute. Enter how many gallons you want to deliver in a session and it tells you the run time to set on your controller, plus the water used per day if you run it daily. Drip emitters commonly come in half, one and two gallon per hour ratings, and matching total flow to your plants avoids both drought stress and waterlogging. Because drip applies water slowly at the root zone, it wastes far less than a sprinkler. Everything is calculated instantly in your browser with no signup.

Frequently asked questions
How does it total a drip system's flow?
It multiplies the number of emitters by the flow rate of each to give the total gallons per hour the whole zone delivers.
How is the run time calculated?
It divides your watering goal in gallons by the total gallons per hour, telling you how long to run the system to apply that amount.
What is daily water use here?
Multiplying the flow by your run time and schedule gives the daily gallons the drip zone uses, useful for planning against a water budget.
