We allow tanker trucks, contractors, and other permitted users to use designated fire hydrants as a temporary water supply. Temporary hydrant use permits are issued based on the following types of use:

• Non transient—Use of a single hydrant to supply water for a construction site.
• Transient—Use of any designated hydrants to fill tanker trucks.

Transient users must meet our backflow prevention requirements and have a backflow inspection before a permit will be issued. For non transient users, CWS will install the hose and backflow prevention assembly on the hydrant. For more information, refer to our Transient and Non-Transient Hydrant Usage Policy.

To apply for a permit, please complete the Transient Permit Application Form or the Non Transient Permit Application Form included in the policy or call our Customer Service Department at 843-727-6800 (press 3 on the main menu).

A list of hydrants designated for transient use is available here.
