A historic town ringed by farmland
Settled in 1760 and incorporated in 1867, Poolesville sits about 26 miles from downtown Washington, surrounded by Montgomery County's Agricultural Reserve but not part of it. It has been called a distant bedroom community for Washington commuters. MD 107 (Fisher Avenue) and MD 109 meet in town, Beall Street runs through, and the Poolesville Historic District, the Seneca Schoolhouse and the Kunzang Palyul Choling temple are local landmarks. The median home was built in 1985.
Town water from deep wells
Poolesville is not WSSC Water territory. The Town draws groundwater from its own wells, drilled 285 to 800 feet into the New Oxford Formation Aquifer. That water needs only minimal treatment, and chlorine is added as the disinfectant. The Town's water quality report says the system contains no lead mains or lead service lines, and it keeps a public service line inventory map; if your property is marked unknown, you can email Town Hall a photo of the incoming line.
The county's Water and Sewer Plan lists Poolesville as served by "Town and onsite systems," so some properties in and around town have their own private wells, and some are not on municipal sewer.
Town sewer and shutoffs
The Town also runs the collection system and an enhanced nutrient removal treatment plant on Beall Street, which treats sewage from WSSC's Jonesville and Jerusalem service areas as well. For a water main break, leak or sewer backup, the Town's emergency numbers are 240-286-3389 and 240-286-3359; Town Hall is 301-428-8927. Most homes have an indoor shutoff where the service line enters, and Town staff will turn the valve at the street connection during business hours, with a call-out fee after 4:00 PM or on weekends. Knowing where your indoor valve is can save you that fee.
Permits
Poolesville Town Hall issues building and zoning, use and occupancy, and utility construction permits. WSSC Water describes itself as the inspection agency for plumbing and gasfitting work in Montgomery County (Permit Services, 301-206-4003), so ask your plumber to confirm with WSSC and the Town which permits your job needs.
Gas
The Town names Washington Gas as its natural gas utility. If you smell gas, leave the house first, then call 911 and Washington Gas at 844-WASHGAS (844-927-4427), option 1. Homes on propane outside town should call 911 and their propane supplier.
