WATER CALCULATOR
Lawn sprinkler water calculator
Estimate water volume and the usage charge for lawn sprinkler water.
How this calculation works
Flow × minutes × uses per day × days gives litres. Divide by 1,000 and multiply by the water price per cubic metre. Use the combined flow from sprinkler heads running at once; pressure changes flow. Sewer, fixed fees and heating costs are excluded.
