Similar to a license, a permit specifically aims to regulate water resources and is divided into three categories:

1. License Permit: An act of authorizing, permitting, or granting the execution of actions or procedures on a temporary or permanent basis.
2. Authorization Permit: An action or result of granting authorization; providing permission for someone to execute an act.
3. Grant Permit: An act of consenting, assigning, transferring, or granting a company the right to perform specific actions.
