## How to Calculate Water Leak Costs
Even a slow drip wastes significant water over time.
### Formula
**Daily Gallons = Drips/min * mL/drip * 1,440 min/day / 3,785.41 mL/gal**
**Annual Cost = Daily Gallons * 365 * Rate**
### Common Leak Rates
- Slow faucet drip (10/min): ~3,000 gal/year
- Running toilet: 200+ gal/day
- Pinhole pipe leak: 10-50+ gal/day

计算示例
A faucet dripping 10 times per minute, 0.05 mL per drip, at $5/1000 gal.
- Daily waste: 10 * 0.05 * 1,440 / 3,785.41 = 0.19 gallons
- Annual waste: 0.19 * 365 = 69 gallons
- Annual cost: 69 * $5 / 1,000 = $0.35
- Note: A faster drip or running toilet wastes far more
