Plumbing in Hammond, IN — What You Should Know
Hammond's Lake Michigan shoreline and steel-mill heritage left dense housing from the 1890s–1930s in Hessville and Robertsdale, where galvanized supply and cast-iron drains still serve many properties. Lake Michigan surface water treated by the city runs moderately hard, and Northwest Indiana's industrial legacy means some neighborhoods sit on filled wetlands with settlement-prone sewer laterals.
