The liquid wastes from kitchens, bathrooms, and wash basins are termed what in sanitation engineering? (Choose the option that is NOT the correct name.)

Introduction / Context:
Sanitary terminology distinguishes between different domestic wastewater streams. Correct terms help in designing dual plumbing, greywater reuse, and selecting appropriate treatment units.

Given Data / Assumptions:

• Kitchens, bathrooms, wash basins discharge without toilet wastes.
• Standard sanitation definitions: greywater versus blackwater.

Concept / Approach:

Wastewater without human excreta is commonly called sullage or greywater. The term sewage, in many texts, includes both sullage and soil water (toilet wastes). Because the question asks for the name that is NOT applicable, “sewage (inclusive of soil water)” is the incorrect specific label for the described stream.

Step-by-Step Solution:

Verification / Alternative check:

Design manuals for on-site systems separate greywater (for potential reuse) from blackwater, underscoring the distinction.

Why Other Options Are Wrong:

(a) and (e) generically describe the stream correctly. (b) is the precise standard term. (d) “None of these” is false because one option is indeed not applicable.

Common Pitfalls:

Using “sewage” loosely for any wastewater; overlooking that many codes treat greywater differently from sewage containing faecal matter.

Final Answer:

Sewage (inclusive of soil water)
