Design the diameter of combined sewer having the following data:

1. Area = 500 hectares

2. Population = 1,00,000

3. Water supply = 150 lits/capita/day

4. Intensity of rainfall = 15 mm/hr

5. Impermeability factor = 0.50

6. Maximum permissible velocity = 2.0 m/sec. Assume reasonable data if necessary.
