Problem: Imagine a residential property with a garden and a house. The garden has a lawn, flower beds, and shrubs, and the house has bathrooms, a kitchen, and laundry facilities. The property receives water from the municipal supply and uses water for various purposes. Calculate the water budget for the property during a given month. Given Data: • Garden area: 500 square meters • Lawn area: 300 square meters • House occupancy: 4 people • Average water consumption per person: 150 liters per day • Average toilet flush volume: 6 liters per flush • Average shower water use: 10 liters per minute • Average laundry water use: 50 liters per load • Average kitchen water use: 20 liters per meal Municipal Supply: • Water supply to the property: 2000 cubic meters (m³) What is the water balance in this residential property? O The residential property's water budget indicates a surplus of 154,380 liters. O The residential property's water budget indicates a shortage of 23,840 liters. O The residential property's water budget indicates a surplus of 23,840 liters. O The residential property's water budget indicates a shortage of 154,380 liters.
To calculate the water balance for the residential property, we need to consider both water consumption and the municipal water supply:
Water consumption by the house:
- Daily water consumption for 4 people: 4 people * 150 liters/person = 600 liters/day
- Monthly water consumption for the house: 600 liters/day * 30 days = 18,000 liters
Water consumption by toilets:
- Assuming 4 toilet flushes per person per day: 4 flushes/person * 6 liters/flush * 4 people * 30 days = 28,800 liters
Water consumption by showers:
- Assuming each person takes a 10-minute shower daily: 10 liters/minute * 10 minutes * 4 people * 30 days = 12,000 liters
Water consumption by laundry:
- Assuming 3 loads of laundry per week: 3 loads/week * 4 weeks * 50 liters/load = 600 liters
Water consumption by the kitchen:
- Assuming 3 meals per day for 4 people: 3 meals/day * 20 liters/meal * 4 people * 30 days = 21,600 liters
Total water consumption by the house: 18,000 liters + 28,800 liters + 12,000 liters + 600 liters + 21,600 liters = 81,000 liters
