Weekly Irrigation Water vs Irrigated Area
Formula
How to Calculate Irrigation Water Needs
Lawns and gardens need about 1 inch of water per week, including rainfall.
Formula
Weekly Gallons = Area * (Need - Rainfall) * 0.623 / Efficiency
Irrigation Efficiency
Overwatering is the most common irrigation mistake, wasting both water and money.
Exemplo Resolvido
3,000 sq ft lawn needing 1 inch/week with 0.5 inches rain at 75% sprinkler efficiency.
- 01Water deficit: 1.0 - 0.5 = 0.5 inches
- 02Weekly gallons: 3,000 * 0.5 * 0.623 / 0.75 = 1,246 gallons
- 03Monthly: 1,246 * 4.33 = 5,395 gallons
- 04Season (26 weeks): 1,246 * 26 = 32,396 gallons
Perguntas Frequentes
How much water does a lawn need?
Most lawns need about 1 inch of water per week during the growing season. Cool-season grasses may need slightly more in heat. Warm-season grasses are generally more drought tolerant.
When is the best time to water?
Water early morning (4-8 AM) to minimize evaporation and fungal disease. Avoid midday watering (high evaporation) and evening watering (promotes fungus).
How does drip irrigation compare to sprinklers?
Drip irrigation delivers water directly to roots at 85-95% efficiency versus 60-75% for sprinklers. Drip uses 30-50% less water for the same plant health.
