Definition
Meaning
Waste matter, especially excrement and other liquid/solid waste from households and industry, carried away in sewers and drains.
The system or infrastructure for removing such waste; often used metonymically to refer to the public health, environmental, or engineering issues associated with waste disposal.
Linguistics
Semantic Notes
A mass noun. Typically refers to the collective, untreated waste. Implies a focus on the waste product itself and its management, distinct from the physical infrastructure ('sewers').
Dialectal Variation

Connotations
Strong negative connotations of filth, pollution, and public health hazard in both varieties. Neutral in technical/engineering contexts.
Frequency
Comparable frequency in both varieties, common in environmental, urban planning, and public health discourse.

Learning
Memory Aids
Mnemonic
Think of SEWAGE as the USAGE of SEWERS: the waste that is put through them.
Conceptual Metaphor
THE BODY POLITIC'S WASTE: Cities/communities are metaphorically seen as organisms, and sewage is their metabolic waste that must be expelled and managed for health.
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid confusing with 'канализация' (kanalizatsiya), which primarily means the sewer *system*. 'Sewage' is the waste itself, better translated as 'сточные воды' (stochnye vody) or 'нечистоты' (nechistoty).
Common Mistakes
- Misspelling as 'sewerage' (which is the system).
- Using as a countable noun (e.g., 'a sewage' is incorrect).
- Confusing pronunciation with 'sew' + 'age' /soʊ.ɪdʒ/; correct is /suː.ɪdʒ/.

FAQ
Frequently Asked Questions
'Sewage' is the waste material itself. 'Sewerage' (less common in US English) refers to the infrastructure system of sewers and pipes that carries sewage away.
No, it is an uncountable (mass) noun. You cannot say 'a sewage' or 'two sewages'. You refer to 'some sewage', 'a lot of sewage', or use a quantifier like 'a volume of sewage'.
Yes, it is commonly used attributively (like a noun modifier) before other nouns, e.g., 'sewage system', 'sewage pipe', 'sewage treatment'. It is not used predictively (e.g., 'The water is sewage' is unnatural).
The word 'sewage' is derived from 'sewer' (via 'sewerage'), not directly from the verb 'to sew'. The pronunciation follows the 'ew' = /uː/ pattern seen in words like 'few', 'chew', which is also present in 'sewer' (/ˈsuː.ər/).
