Why sewage should not be allowed to stagnate in drains?

Answer»

dy 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❤️
