When a pipe breaks or a drain starts pushing sewage back into a Waldorf home, close the main water valve before anything else; a gas smell means everyone gets outside before a single call is made. Waldorf sits in Charles County, so its water, sewer and permit contacts differ from the Prince George's suburbs next door. Call the number on this page to be connected with a local plumber in Waldorf.

Is the leak mine or the County's?
Waldorf has no town government, so the Charles County Department of Public Works runs both the public water and the sewer lines here. If water is welling up from the street, a hydrant is leaking or a sewer manhole is overflowing, that belongs to the County's Utilities Division, reachable at 301-609-7400. Anything inside your walls, under the slab or along the lines crossing your own lot is a job for a plumber. A backup that hits only your house almost always points to your own drain or lateral rather than the County main.
The drinking water itself comes mostly from deep County wells in the Patapsco and Magothy aquifers, blended with water bought from WSSC Water. That mix doesn't change what you do in an emergency, but it explains why Waldorf's water report comes from Charles County rather than WSSC.
What should I do if I smell gas?
Washington Gas supplies natural gas in Charles County. Leave the house right away without switching lights or appliances on or off, then call 911 and the Washington Gas emergency line at 844-WASHGAS (844-927-4427) - Select option 1, from somewhere safe outside. Once the utility has made things safe, a plumber can find and fix a leaking fitting or appliance connection. Many homes are all-electric; if yours has no gas service, an odor still deserves a 911 call.
Will a Waldorf emergency repair need a permit?
Possibly. Because Waldorf is outside the WSSC permit area, plumbing and gas permits here go through Charles County Codes, Permits and Inspection Services in La Plata (301-645-0692), whose code is based on the International Plumbing Code and International Fuel Gas Code. A plumber can stop the leak tonight and handle any paperwork for a permanent fix such as a replacement water heater or new gas piping. Lawn irrigation systems in the County also need a reduced pressure zone backflow assembly that is tested every year, so a spring start-up leak may involve that device.
Most homes in the 20603 ZIP code were built after 1980, which means fewer original cast iron drains than older suburbs. Emergencies here tend to involve water heaters, supply hoses, frozen pipes in exterior walls and lines running through finished basements.
A quick local note
Before a cold night or a trip away, find the main shutoff, usually where the water line enters near the front foundation or in a basement utility area, and make sure it turns. If you live along the US 301 corridor in St. Charles or Smallwood Village and aren't sure who bills your water, check the statement from the County. No arrival time is promised on emergency calls; it depends on the hour and the plumber's schedule.
