Irrigation Calculators

Plan an irrigation system that actually fits your yard. These calculators turn coverage areas, pipe runs, and water needs into material quantities, cost estimates, and project-ready results you can act on right away.

Irrigation planning checklist

  1. Map irrigated areas, plant needs, and the water source before choosing components.
  2. Measure runs and identify zones or drip areas that need separate control.
  3. Use calculator outputs as a parts-planning check, then verify pressure, flow, local rules, and utility locations.

Common planning pitfalls

  • Sizing from area alone without confirming available flow and pressure.
  • Combining plant areas with different watering needs on one schedule.
  • Installing before locating utilities or checking local backflow requirements.
