Question

Match the types of water carriage system in Group-I with their corresponding functions in Group-II.

 

• A. P–2, Q–4, R–1, S–3
• B. P–2, Q–3, R–5, S–4
• C. P–1, Q–4, R–5, S–3
• D. P–1, Q–3, R–1, S–4

Hint:

Understanding the key features of water carriage systems, like whether sewage and stormwater are combined or separated, helps in selecting the right type of system for different urban settings.

Answer 1

The Correct Option is A

P (Combined system): Rainwater from roofs enters the sewer with sewage; remaining storm water flows separately. Corresponds to P–2.
\n Q (Vacuum sewer system): Negative pressure in the sewer draws sewage and air from various sources. A pump moves waste from residences to the low-pressure sewer line. Corresponds to Q–4.
\n R (Partially separate system): Sewage from buildings is channeled through one set of sewers, and storm water through a separate network. Corresponds to R–1.
\n S (Pressurized sewer system): A pump transfers waste from residences to the low-pressure sewer line. Corresponds to S–3.\n\nThe correct matching is (A) P–2, Q–4, R–1, S–3.
