How to Apply for Hydrant Use

If you are interested in any of the above listed types of hydrant usage please contact our Cross Connection Control Supervisor at 803-359-8373.

Transient Hydrant Usage

Transient hydrant usage will be allowed by a permit system.  All vehicles that draw from a Commission hydrant that is not equipped with a non-transient device, must possess a transient hydrant usage permit.


Applicants must make an appointment with the Commission’s Cross Connection Control Supervisor to have the truck, tank, etc. inspected.  At that time a Transient Hydrant Usage Permit Application will be filled out and appropriate fees will need to be paid.  Permits are for the period of July 1 through June 30 of the following year.

The truck, tank, etc. must be equipped with an air gap or permanently mounted SCDHEC approved backflow prevention assembly which has been tested within thirty days from the date of application.

Use of Permit

Upon completion of the application and payment of fees, the Commission will issue a Water Usage Permit Decal.  This decal must be clearly displayed on the driver’s side window of the approved vehicle.  Decals will be color-coded for each calendar year.  The Commission will notify customers thirty days in advance of their decal expiration.

The customer is responsible for notifying the Commission prior to each hydrant use.  The customer must specifically identify which hydrant is being used and the amount of water being drawn from the hydrant.  The customer will not be charged separately for water, but is requested to closely monitor usage.

Temporary hydrant use permits will be required on all stationary sources.  These permits will allow temporary un-metered water usage for either up to ninety (90) days or twelve (12) months.


Application and appropriate fees must be paid in full prior to the installation of any assembly and are based on the requested size of connection.  Hydrant use permits will be issued and approved only for SCDHEC approved water mains.  The applicant must know the exact location of the hydrant that they wish to utilize.
