Question

why sewage should not be allowed to stagnate in drains?

Answer 1

Hey buddy here is ur answer!
Rainwater may leak in through roofs, windows, or other damaged areas. While clean water does not bring in contaminants with it, it can become a breeding ground for bacteria if notcleaned up quickly. Contaminated sources of standing water include flooding and sewage backups.

I hope it help for u❤️
