Neutral technical term in both varieties. Connotes public utility, urban infrastructure, and potential sources of disruption (burst mains).

- Do not confuse with 'water pipe' ('водопроводная труба'), which is more general and can refer to domestic plumbing.
Common Mistakes
- Using uncountably: *'There was a damage to the water main.' (Correct: 'damage to the water main').
- Confusing with 'sewer main' or 'drain'.
- Misspelling as 'water mane'.
