In an area that measures 3 feet wide by 120 feet long bordered by impervious structures, what device do I need to install?

• A. Sprinkler System
• B. Drip Irrigation
• C. Micro Irrigation
• D. Flood Irrigation

Answer: (B)

When you have a narrow strip of bed bordered by impervious surfaces, the goal is to apply water directly where the plants need it and keep it from spilling onto walls or pavement. Drip irrigation does that by delivering water slowly right at the root zone through emitters placed along the length of the bed. This localized, low-volume irrigation minimizes runoff, reduces evaporation losses, and prevents water from wetting impervious borders, which would waste water and might cause drainage issues. In this setup, sprinklers would spray water over a wide area, much of which would hit the surrounding structures or run off the border, and flood irrigation would require a much larger area and complete surface wetting that isn’t suitable here. Drip irrigation is specifically designed for long, narrow spaces like this, offering efficient, targeted watering. In practice, you’d lay out tubing along the length with emitters every so often, and include a filter and pressure regulator to keep the emitters working reliably.
