DC Water owned hydrants. The dataset is updated on a daily basis. The information provided is limited to the best available data in DC Water’s possession at the time the dataset was loaded.More information about our HydrantsA fire hydrant is connected to the water main that runs below the street or sidewalk. To use the hydrant for firefighting, the nozzle cap is removed, a hose is attached to the nozzle and the operating stem on top of the hydrant is turned. Hydrants come in a variety of shapes and colors. Fire flow is not determined by the attractiveness or color of the hydrant, nor does a missing cap or slight defect render it inoperable.
