Which irrigation type is the least expensive for covering a small area?

• A. Drip system
• B. Fixed system
• C. Sprinkler system
• D. Portable system

Answer: (A)

For a small area, the most cost-effective approach is drip irrigation because it uses minimal materials and install effort while delivering water directly to the root zone where plants need it. A basic drip setup—poly tubing, emitters, and a shutoff valve—fits a tiny bed with little trenching and can be installed by a DIY homeowner, keeping both materials and labor costs low. Drip systems also waste less water, which lowers ongoing costs and reduces maintenance needs over time.

Fixed systems and sprinkler systems tend to require more piping, more heads or zones, and often a controller, which increases upfront and ongoing costs even for a small area. A portable hose-and-sprinkler setup might seem cheap at first, but it typically provides uneven coverage and can waste water, making it less economical in practice for consistent small-area irrigation.
