Alhambra, Monterey Park, and Rosemead residents are not allowed to wash cars on the street in front of their houses, World Journal （世界日报) reports. The sewage system is directly connected to the ocean, Alhambra Vice Mayor Stephen Sham told the Chinese publication, and the city prohibits washing cars on the street in order to prevent pollution caused by detergents.
Residents can wash their cars on their private property, according to Alhambra City Manager Assistant Chris Paulson, but the city encourages using a bucket instead of spraying with a hose and using non-toxic, biodegradable soap.
"The hope is that most of the water will be directly discharged into their landscape, where it can filter through, rather than flow directly to the storm drain and ocean," Paulson said Thursday in an email to Alhambra Source.
