Irrigation & rainwater calculators

Measure delivery before selecting runtime. Use a bucket test for outlet flow, a catch-cup test for application rate, or product ratings to total drip flow. Water-budget estimates account for a chosen target, effective rainfall and efficiency; flow arithmetic does not size pipes or determine operating pressure.

• Irrigation Water Budget and Runtime CalculatorConvert a stated irrigation depth into water volume and runtime.
• Sprinkler Catch-Cup Audit CalculatorCompare four catch-cup depths and estimate average application rate from a timed test.
• Drip Emitter Flow and Runtime CalculatorSum nominal emitter flow and estimate runtime for a target water volume.
• Bucket-Test Water Flow CalculatorEstimate source flow from the time needed to fill a known-volume container.
• Drip Tape Length and Flow CalculatorEstimate drip-tape length and nominal total flow from row layout and product rating.
