In many locations persons impersonating utility company employees knock on doors and state that they work for your utility company and are there to test the water inside your house. These persons once inside your house will go through the motions of testing water and will engage you in conversation while their accomplices steal your personal belongings. DWU customers are urged to contact DWU administrative offices if anyone tries to enter your house on the pretense they are utility company employees. It should also be noted that the elderly are the first choice of these scammers and thieves since it is the elderly that are most concerned about their health; but anyone can fall victim.
