In an effort to protect the public water supply against contamination or pollution the City of Douglas, Arizona has made the decision to take steps to enforce its backflow prevention rules and regulations. Eddie Gonzales, environmental specialist for the city of Douglas stated the ordinance regarding backflows and cross connections has been on the city books since 1993. However, since 1993 the city has not been enforcing the regulations.

The city is working to move forward and start notifying commercial businesses that they will have an inspection of their backflow due by a certain date. That inspection will be required at least once a year. The city recently sent out a letter to all Douglas commercial property owners including apartment complexes advising them that beginning with their August 2019 utility bill, a $1 monthly fee will be assessed to their bill for backflow prevention and administration costs.
