Basic Charges
Monthly utility bills are generally comprised of the aggregate of an Availability Charge, a Debt Service Recovery
Charge, and a User Fee which are described as follows.

Availability Charge 
A monthly charge for water and/or sewer for making utility service available the amount of which for each customer shall be based on the size of the customer’s water meter. Payment of an Availability Charge does not entitle a customer to any minimum usage allowance.

Debt Service Recovery Charge 
A  monthly charge for water and/or sewer based on the debt service obligations of the Authority the amount of which for each customer shall be based on the size of the customer’s water meter.

User Fee 
A charge based on volumetric utility usage determined from meter readings or other method acceptable to the Authority the amount of which increases as volumetric usage increases.

In some cases utility service may be billed at a Bulk Rate or Flat Rate.

If a customer has no volumetric usage but is nevertheless required to connect to ONWASA’s water or sewer
system, the customer shall pay a minimum monthly utility bill consisting of the applicable Availability Charge and Debt Service Recovery Charge.
