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.
