Question

For trench type of sanitary filling the amount of land required for 2 meter deep trench for 10000 population is

• A. 1 acre
• B. 2 acre
• C. 3 acre
• D. 4 acre

Answer 1

The Correct Option is A

To determine the amount of land required for a sanitary trench fill for a population of 10,000 people with a trench depth of 2 meters, we need to follow these calculations:

Assumption: Average waste production per person is 0.05 cubic meters per year. For 10,000 people, annual waste volume is:
0.05 × 10,000 = 500 cubic meters

With a 2-meter deep trench, the trench area required annually is:
500 cubic meters / 2 meters = 250 square meters

Converting 250 square meters to acres (since 1 acre = 4046.86 square meters):
250 / 4046.86 ≈ 0.0618 acres

Over the span of several years, it's typical to plan for more space to accommodate multiple years, additional landfill space, buffer zones, and operational needs. Therefore, it's estimated that 1 acre is sufficient to manage landfill requirements for an extended period for a community of this size.

Thus, the correct answer is 1 acre.
