Drip Irrigation Calculator

Drip irrigation delivers water directly to each plant's root zone through a network of tubes and drippers, rather than flooding the whole field. This typically cuts water use by 30–50% compared to flood irrigation while often improving yields, since water goes where the plant needs it instead of evaporating or running off — it's especially effective for row crops, vegetables and orchards.

Enter the number of plants, drippers per plant, each dripper's flow rate in litres per hour, and how many hours you run the system per day. The calculator multiplies these together to give your daily water use, then extends it to weekly and monthly totals for planning your water source and pump capacity.

Water/day = Plants × Drippers × Flow × Hours
