Fire Hydrant Maintenance

To be sure that fire hydrants are ready when they're needed, WSSC Water crews physically inspect each hydrant regularly. Because there are so many hydrants - more than 43,000 spread out over 5,844 miles of water pipe - they're inspected on a three-year cycle, with about 13,000 inspections conducted in the two counties every year. Most inspections are done in the summer, with more than 10,000 completed between April and September.

Fire hydrants are made of cast iron and can last more than 50 years. However, internal working parts, such as gaskets and seats, require routine maintenance or replacement, which is why we have a proactive inspection program. During a typical inspection, WSSC Water crews:

  • Visually inspect the fire hydrant
  • Measure the water pressure and flow rate, and compare it to historical data
  • Perform routine maintenance (oil and grease cylinders, exercise valve, replace caps as necessary, etc.)
  • Check the hydrant's age

If a hydrant needs to be taken out of service, our goal is to repair it within seven calendar days, and we achieve that goal 95 percent of the time.


How to identify a WSSC Water fire hydrant

The easiest way to identify a WSSC Water hydrant is by its color: all WSSC Water fire hydrants have a green top and a white or light gray body.

How you can help

Fire Hydrant Meter Rentals

On a limited basis, WSSC Water leases fire hydrant meters to individuals and businesses that want to purchase WSSC Water potable water without paying sewer charges. Hydrants are leased for a minimum of two weeks to a maximum of six months.

Fire hydrants in most of Prince George's and Montgomery counties can be used; however, areas of Bowie, Rockville and all of Poolesville have their own water systems, so WSSC Water meters cannot be used on those fire hydrants. The easiest way to identify a WSSC Water hydrant is by its color: all WSSC Water fire hydrants have a green top and a gray body.

A 3/4" meter, which is used with a standard garden hose, provides a flow rate of about 25 gallons per minute, or 1,500 gallons per hour. A 3" meter, used with a 2 1/2" fire hose, flows at 250 gallons per minute, or 15,000 gallons per hour.

A security deposit is required for the fire hydrant meter rental: $379.00 for a 3/4" meter and $2,420.00 for a 3" meter. Security deposits must be paid by certified check, cashier's check, treasurer's check or money order. If customers have a WSSC Water account in "good standing" (three years of on-time payments with no returned checks), we will accept personal checks.

If you lease a meter for six months, at the end of each month, you must email meter readings (including all zeros) to fhrentalprogram@wsscwater.com. Be sure to include your permit number and full name (or company name). (3/4" hydrant meters will have a seven-digit reading, 2 1/2" hydrant meters will have an eight-digit reading.)

Fire hydrant meters cannot be leased for more than six months. The meter must be returned to a WSSC Water rental facility on or before the expiration date. If you need another fire hydrant meter, a new permit will be issued. Note that deposits do not transfer to a new permit.

Backflow Prevention

“Small” ¾” meters are outfitted with a ¾” male hose thread connection and an integral backflow prevention device. No additional protection is required unless the hose will be connected directly to a high-hazard water-utilizing piece of equipment.

“Large” 3” meters have a 2-1/2” male hose thread connection and are not outfitted with a backflow prevention assembly. Anyone who leases a large WSSC Water meter must provide an ASSE 1013 RP Backflow Prevention Assembly for every application (other than for an approved tanker with an inspected and unaltered air gap connection). See WSSC Water Plumbing and Fuel Gas Code sections 111.5.11 & 506.7.3.

Permit Requirements

Installing a backflow prevention assembly for temporary water use does not require a permit or inspection, but it must comply with all applicable code requirements in WSSC Water Plumbing and Fuel Gas Code, Chapter 5, including testing and reporting requirements.

Testing Intervals

Backflow Prevention Assemblies used with a Large WSSC Water Fire Hydrant Meter rental are to be tested and reported every six months. See WSSC Plumbing and Fuel Gas Code Sections 111.5.11 & 506.7.3.

Reporting

When completing a test report for a Backflow Prevention Assembly, which serves along with a Large WSSC Water Fire Hydrant Meter, the contact information (mailing address) is to be for the owner of the Backflow Preventer and the address provided must be their permanent office, not a temporary location. List the actual location of the Backflow Preventer in the Location Field and the Assembly Address Field which are part of the “facility address” section. Also be sure to select “fire hydrant meter rental” as the downstream process regardless of the actual usage; that should be added to the comments section.

Restricted Fire Hydrants

Fire hydrant meters can be used only on WSSC Water fire hydrants, which are easily identified by their green tops and white or light grey bodies.

Seasonal Applications

Garden Centers, Farm Stands, and similar facilities with permanent piping or permanent and/or heated structures (including mobile buildings and trailers) or any property with an in-ground irrigation system, cannot use a fire hydrant meter rental for a water connection (see WSSC Water Plumbing and Fuel Gas Code sections 111.5.11 & 506.7.4.).
