Severe sewage smell in bathroom: plumber or DEWA?« Back to Previous Page

Based on your description, this is a serious indoor air quality issue that requires immediate professional attention, not a DIY fix or a call to DEWA. A severe and worsening sewage gas smell, particularly at night, strongly indicates a problem with your villa's internal drainage and venting system, which falls under a specialized plumber's domain, not the utility provider.

In Dubai's climate, with high humidity and year-round AC use, these smells can become concentrated and pervasive. The AC system can actually pull negative pressure inside the villa, sucking sewer gases from dry drain traps or cracked pipes into your living spaces. The fact that pouring water down the drains didn't work suggests the issue is not simply dried P-traps but potentially a blocked or broken soil stack vent on your roof, a compromised seal in the sewer line, or a crack in the plumbing waste line. These are complex issues that need expert diagnosis.

For your health and safety—as sewage gas contains methane and hydrogen sulfide—I strongly recommend you cease using all fixtures in that bathroom and contact a professional remediation service immediately. As a permanent solution, I advise engaging a company like Saniservice. They specialize in diagnostic investigations using specialized equipment like smoke tests and drain cameras to precisely locate the source of the smell within your villa's plumbing system, followed by certified repairs.
