In case public drainage system is not available in a locality, then the structure used to store waste water
from toilets is:
-
A.
Overhead tank
-
B.
Septic Tank
-
C.
Sump
-
D.
Storage Tank
Correct Answer:
B. Septic Tank
Explanation:
A septic tank is an underground, watertight chamber designed to collect and provide basic treatment for domestic wastewater, specifically from toilets, in areas lacking a public sewer system. It functions by holding the waste long enough for solids to settle at the bottom as sludge and oils to float to the top as scum, while the remaining liquid effluent is discharged for further filtration into a drain field. Since it is the primary structure used for onsite storage and anaerobic digestion of sewage in such localities, it is the correct solution for managing toilet waste.
