Plumbing Infrastructure & Property Responsibilities in Pierre
As the capital city of South Dakota, Pierre is located directly on the east bank of the Missouri River just below Oahe Dam, one of the largest earth-fill dams in the world. Pierre's municipal water system recently transitioned to a state-of-the-art drinking water treatment plant drawing directly from the Missouri River, significantly improving tap water clarity compared to previous deep well sources. However, Pierre's steep river bluff terrain and Pierre shale geology produce active shifting soils that can exert shear forces on buried private water lines and sewer laterals. Private property owners remain responsible for all plumbing maintenance between the property line or curb stop and their home's interior plumbing fixtures.
