Baltimore County surrounds the city on three sides, and most of its suburbs share the city's water system: Baltimore City DPW supplies the water, while Baltimore County maintains local sewers. Permits come from the county's Department of Permits, Approvals and Inspections in Towson. Northern parts of the county rely on private wells and septic.

Housing and plumbing across the county
The county's inner suburbs — Catonsville, Arbutus, Parkville, Dundalk, Essex — grew quickly from the 1920s through the 1960s, so cast-iron drains, clay sewer laterals and galvanized supply pipe are common. Newer development in Owings Mills, Perry Hall's Honeygo area and White Marsh is more likely to have PVC drains and copper or PEX supply lines. North of the Beltway, many homes in places like Hereford and Sparks are on wells and septic.
