About Hydrant Permits
Hydrant Permits allow inspected and approved customer water tank trucks/trailers to access predetermined hydrants throughout TVWD's service area. These hydrants are designated with green painted caps/tops. To learn more about obtaining a hydrant permit, see our FAQ section below.
Unauthorized hydrant use and/or use of a non-approved (un-inspected) tank is subject to the penalties listed in our Bulk Water Rates.
