Why is the Right Capacity Important?
A tank that is too small will be insufficient during water cuts, while a tank that is too large creates unnecessary cost and hygiene risk.
Basic Calculation Formula
Capacity = Daily Water Consumption × Reserve Days
Daily Consumption by Usage Area
Residential
- Per person: 150-200 liters/day
- 4-person apartment: ~800 liters/day
- 50-unit apartment building: 40,000 liters/day (minimum 2 days = 80 tons)
Commercial Buildings
- Office: 50-80 liters/person/day
- Restaurant: 70-120 liters/person/day
- Hotel: 200-300 liters/room/day
Industrial Facilities
Varies according to production process. Process water, cooling water and personnel use should be calculated separately.
Example Calculation
Scenario: 100-unit residential complex, average 3 people/unit
- Total people: 300
- Daily consumption: 300 × 180 liters = 54,000 liters
- 2-day reserve: 108,000 liters = 108 tons
- Recommended Tank: 120-ton modular tank
