Basement waterproofing in South Williamsport

Wet basement help for the borough on the south bank, home of the Little League World Series.

South Williamsport is a borough of 6,261 people (2020 census) across the West Branch from the city. The river forms its northern edge, and Bald Eagle Mountain rises to the south. That squeeze between water and ridge shapes how a lot of basements here get wet: houses near the mountain take runoff coming downhill, while lower streets closer to the river deal with groundwater that rises when the ground stays soaked.

What should South Williamsport homeowners watch for?

  • Water entering on the uphill wall after long rains
  • Sump pumps that run for days after a storm
  • Seepage near Hagermans Run and other low spots
  • Window wells that fill and leak through basement windows

What about the levee here?

The borough is part of the Greater Williamsport levee system. The U.S. Army Corps of Engineers has listed the South Williamsport levees as needing maintenance, and repair and recertification work has been funded in recent years. A levee helps against river flooding but not against groundwater under the slab, so a working sump and drain still matter.

Permits

South Williamsport is its own borough, so the City of Williamsport's Bureau of Codes isn't the place to ask. Check with the borough office about excavation, plumbing or structural work, and have your contractor confirm what's needed before work begins.

Common questions

Why does my basement leak on the side facing the mountain?

Water moving downhill from Bald Eagle Mountain collects against the uphill wall. Grading, gutters, an exterior footing drain or an interior drain on that wall are common fixes.

Is South Williamsport covered by the levee?

Parts of the borough are protected by the Greater Williamsport levee system. Check your flood zone status with the borough or your insurance agent.
