Where We Drill: the Ten-County Metro

Columbus, OH HDD service area — 10 component counties, principal and satellite cities — The Central Ohio service area — U.S. Census Bureau county boundaries; cities marked are where crews most often mobilize.

The service area is the OMB-defined Columbus metro — Franklin and its ring from Delaware and Union across to Licking, Fairfield, and Pickaway, and out to the plateau counties of Hocking, Perry, and Morrow's north. County pages below carry the local picture: the corridors, the boundary, and the authorities whose permits govern crossings.

Franklin County

The core: Columbus, the confluence, the campus belt, and the eastern corridor's edge.

Licking County

The corridor county: the fab program, New Albany's east edge, and the boundary itself.

Delaware County

The polished north: Ohio's growth leader, reservoir country, and shallow limestone reaches.

Union County

The Honda west: Marysville's EV hub, the 33 corridor, and Big Darby's headwaters.

All component counties: Franklin · Delaware · Fairfield · Licking · Madison · Pickaway · Union · Morrow · Hocking · Perry.
