The map below is powered with information from DC Water and Sewer and is up to date as of Feb 10, 2010. Simply drag the map around or key in an address to re-center the map. It will always show you the 40 hydrants nearest to the center of the map. It’s possible those hydrants will be off-screen; If you do not see any markers try zooming out to a larger area.
The only published data we have at the moment is for DC hydrants. If we get GIS data for VA or MD locations we’ll add it in.
