How this estimate works

Dripline feet = row length × rows. Approximate emitter positions = dripline inches ÷ emitter spacing.

The arithmetic describes a planning volume or sketch. Local climate, plant needs, pressure, flow, rainfall, and equipment ratings determine actual irrigation design.

Before you order

  • Check local weather and plant water needs.
  • Confirm equipment pressure, flow, and manufacturer coverage.
  • Check local water rules and the site drainage path.

Planning estimates can differ from delivered or installed quantities.
