What will be their water requirement if a college hostel has one thousand students?

Correct Answer

For a college hostel with 1,000 students, the water requirement is calculated by multiplying the number of students by the average consumption per person.

Using the prescribed consumption of 135 L per day per person for urban areas: 1,000 students × 135 L/person/day = 1,35,000 litres per day.

If using rural norms of 55 L/person/day: 1,000×55000 \times 55 = 55,000 litres per day.

The prescribed usage is 55 L per day for rural areas and 135 L per day for urban areas as per the Jal Jeevan Mission.

For More Understanding

Explanation

The chapter on page 27 provides Table 5.7 for recording data on increased demand in scenario 2. Students need to fill in: Number of additional consumers of water (1,000), Average consumption per person (from earlier data or prescribed norms), Total increase in consumption, and Increase in overall consumption in the locality. The prescribed usage is 55 L per day for rural areas and 135 L per day for urban areas as per the Jal Jeevan Mission.

Solution Steps

  1. Step 1: Identify number of additional consumers: 1,000 students.

  2. Step 2: Determine average consumption per person from collected data or prescribed norms.

  3. Step 3: For urban areas (typical for college hostels): 1,000×135000 \times 135 L/person/day = 1,35,000 L/day.

  4. Step 4: For rural areas: 1,000×55000 \times 55 L/person/day = 55,000 L/day.

  5. Step 5: Record the total increase in consumption and impact on locality in Table 5.7.
