Question

If the per capita water supply is \(150~\mathrm{L/day}\) and \(80\%\) becomes sewage, the sewage generated for \(10{,}000\) people is

• A. 1.0 MLD
• B. 1.2 MLD
• C. 1.5 MLD
• D. 2.0 MLD

Hint:

Sewage generated: \[ \boxed{ \text{Sewage} = 0.8\times (\text{Water Supply}) } \] (Usually \(80\%\) of water supplied becomes sewage.)

Answer 1

The Correct Option is B

Water supplied per day, \[ 150\times10,000=1,500,000\ \text{L/day} \] Since \(80\%\) becomes sewage, \[ 0.8\times1,500,000=1,200,000\ \text{L/day} \] \[ =1.2\ \text{MLD} \] Hence, \[ \boxed{1.2\ \text{MLD}} \] Therefore, \[ \boxed{(B)} \]
