What is the increase in the demand for water if a housing society of 100 homes is constructed near your village? You can estimate four people per family.
For a housing society of 100 homes with 4 people per family, the total number of additional people = = 400 people.
If average consumption per person is 55 litres per day (rural) or 135 litres per day (urban), the total increase in water demand = = 22,000 litres per day (rural) or = 54,000 litres per day (urban).
The chapter on page 26 provides Table 5.6 for recording data on increased demand. The Jal Jeevan Mission prescribes 55 L per day for rural areas and 135 L per day for urban areas.
Explanation
The chapter on page 26 provides Table 5.6 for recording data on increased demand. Students need to calculate: Number of families (100), Total number of members ( = 400), Average consumption per family, Total increase in consumption, and Increase in overall consumption in the locality. The Jal Jeevan Mission prescribes 55 L per day for rural areas and 135 L per day for urban areas.
Solution Steps
Step 1: Calculate total number of people: 100 families × 4 people per family = 400 people.
Step 2: Determine average consumption per person (from earlier data collection or prescribed norms).
Step 3: For rural areas: 400 people × 55 L/person/day = 22,000 L/day.
Step 4: For urban areas: 400 people × 135 L/person/day = 54,000 L/day.
Step 5: Record the increase in overall consumption in the locality in Table 5.6.
