Drip vs Sprinkler Comparison
💧 Drip Irrigation
—
- 90–95% water efficiency
- Delivers water to roots directly
- Reduces disease from wet foliage
- Best for vegetables & beds
🌦 Sprinkler
—
- 65–75% water efficiency
- Covers large areas quickly
- Some loss to evaporation
- Best for lawns & open beds
Reference Evapotranspiration (ET₀) by Season & Climate
| Climate | Spring (mm/day) | Summer (mm/day) | Autumn (mm/day) | Winter (mm/day) |
|---|---|---|---|---|
| Arid | 4.0 | 8.0 | 3.5 | 2.0 |
| Temperate | 2.5 | 4.5 | 2.0 | 0.5 |
| Humid | 1.5 | 3.0 | 1.2 | 0.3 |
Water-Wise Tips
- Water in the morning: Reduces evaporation loss by up to 30% compared to midday watering.
- Mulch your beds: A 5–8cm layer of mulch reduces soil water loss by 25–50%.
- Group plants by need: Keep high-water and low-water plants in separate zones.
- Check soil before watering: Push a finger 5cm into soil — if it's moist, skip the watering session.
- Drip lines for beds: Installing a drip system can reduce water use by 30–50% vs hand watering.
- Avoid clay compaction: Aerate clay soils annually to improve drainage and reduce runoff.
