​Billing & Account Information

​Opening a New Account:

You may now request to open an account Online or you may call the City of Dallas Water Utilities Department (DWU) Customer Service at (214) 651-1441 on weekdays. Or stop by our Customer Service Lobby in Room 2D South at Dallas City Hall, 1500 Marilla Street.

Deposits:

Deposits will be billed on your first bill. However, a deposit is not required if you meet at least one of the following criteria:

  • Your credit history with DWU is good;
  • You are at least 65 years old;
  • You own, or are in the process of buying, the property to be served; 
  • You have a letter of guarantee from another person who has a good credit history with DWU; or 
  • Your account with another utility was not delinquent and timely payments were made for 12 consecutive months.

Some customers who do not need to pay a security deposit when they apply for service are asked to do so later because they become delinquent or develop an unsatisfactory credit history with DWU.
