Irrigation Water Usage Calculator
Calculate how much water your lawn or garden needs with our comprehensive calculator. Determine optimal watering schedules based on area, plant type, climate conditions, and irrigation system efficiency.
Step 1: Area & Plant Type
Understanding Water Requirements
Different plants have varying water needs. Lawns typically require 25-40mm of water per week in summer. Climate factor adjusts for local evaporation rates.
Step 2: Irrigation System
About Irrigation Efficiency
Different irrigation systems have varying efficiency levels. Drip and subsurface systems are most efficient (85-95%), while sprinklers lose more water to evaporation and runoff.

Water Usage Breakdown
Water Usage Formula
Water Required = Area × Water Depth × Climate Factor / System Efficiency
To calculate water needs: Multiply area by required water depth, adjust for climate, then divide by system efficiency to account for losses.
