Access Hydrants

The first and main purpose of hydrants is for fire protection. For that reason, fire fighters in Loudoun County have unlimited access to hydrants within the Loudoun Water service area and they require no permit or meter to use them. As a convenience, Loudoun Water issues hydrant meter permits to others who would like to access them for large quantities of non-potable water, such as for construction flushing and flush trucks. Please note that hydrant meters can only be used on yellow hydrants within the Loudoun Water service area.

The first step in accessing a hydrant is to obtain a permit for a hydrant meter. Please bring the following to our Operations & Maintenance Facility: a valid, state-issued identification card (i.e. a driver’s license), a Virginia (or Loudoun County) business license number, a business card, federal tax identification number, and a check for your deposit. Loudoun Water will make a photocopy of each item for the file. All customers are required to read and sign our permit indicating the proper use of hydrants and their locations. The signed permit is kept on file with identification papers for the life of the agreement. Each permit is valid for one year from the date signed. Before the expiration date, a new permit may be signed to keep the same hydrant meter for an additional year. Each customer applying for a new hydrant meter shall pay a $25 permit charge to defray the administrative costs associated with each hydrant meter account. This will be added to your first bill.

Once you have a hydrant meter, you must submit readings to us by the 15th of each month by fax at 571.223.2595 (download a Word version guide), by phone at 571.291.7850, by sending an email to hydrantmeter@loudounwater.org by completing the online Hydrant Meter Reading Form.
