What is a Homestead Water Usage Calculator?
A Homestead Water Usage Calculator estimates total daily water consumption for your household, livestock, and garden. By entering your family size, animal counts, and garden area, you get a comprehensive water budget that helps size wells, pumps, storage tanks, and rainwater collection systems.
Water is one of the most critical resources on a homestead. Understanding your actual needs prevents undersized wells, inadequate storage, and dry-season shortages. This calculator breaks down usage by category so you can identify the biggest water demands and plan accordingly.
Livestock Water Requirements
| Animal | Gallons/Day | Gallons/Year |
|---|---|---|
| Beef Cattle | 12 | 4,380 |
| Dairy Cow (milking) | 30 | 10,950 |
| Horse | 10 | 3,650 |
| Pony / Mini Horse | 5 | 1,825 |
| Dairy Goat | 4 | 1,460 |
| Meat Goat | 2 | 730 |
| Sheep | 2 | 730 |
| Pig (market hog) | 4 | 1,460 |
| Chicken | 0.1 | 37 |
| Duck | 0.2 | 73 |
| Turkey | 0.15 | 55 |
| Rabbit | 0.15 | 55 |
| Alpaca | 2 | 730 |

Frequently Asked Questions
How much water does a homestead use per day?
A typical homestead with a family of 4, 10 chickens, 2 dairy goats, and a 1,000 sq ft garden uses about 150-250 gallons per day: 80-100 gallons for household, 8-10 gallons for goats, 1 gallon for chickens, and 50-100 gallons for garden irrigation (depending on weather).
How many gallons of water does a cow drink per day?
A beef cow drinks 8-15 gallons per day depending on temperature and feed moisture. A lactating dairy cow drinks 25-40 gallons per day — milk production requires significant water intake. In hot weather, consumption can increase 50% or more.
How much water does a garden need?
Gardens need about 1 inch of water per week, which equals 0.62 gallons per square foot. A 1,000 sq ft garden needs roughly 620 gallons per week, or about 90 gallons per day. Drip irrigation reduces this by 30-50% compared to overhead watering.
What size water tank do I need for a homestead?
A common approach is 3-7 days of storage capacity. If your homestead uses 200 gallons/day, a 1,000-1,500 gallon tank provides adequate buffer. For rainwater harvesting, size tanks based on roof collection area and dry season needs — often 2,500-10,000 gallons for significant self-sufficiency.
How do I calculate well pump size?
Divide your daily water usage by hours you want to pump. If you use 300 gallons/day and want to pump for 2 hours, you need 150 GPH (2.5 GPM). For peak demand (multiple fixtures running), size for 5-10 GPM minimum. Well recovery rate must also be considered.
