If you need a water source for construction, demolition, dust control or for similar purposes, we recommend using a Temporary Water Connection, a water truck, or an on-site water storage tank. If these water sources are not available or are prohibited at your project site and you wish to use a fire hydrant as a temporary water source, you must first obtain a Fire Hydrant Use Permit from DC Water. This permit will authorize the applicant to operate a particular fire hydrant for the purpose of obtaining water on a temporary basis.
