Public utilities provide electric, gas, water or telephone service to customers in a specified area. Utilities have a duty to provide safe and adequate service on reasonable terms to anyone who lives within the service area on without discriminating between customers. Because most utilities operate in near monopolistic conditions, they can be heavily regulated by local, state, and federal authorities. Generally, the local and state agencies are called Public Service Commissions (PSC) or Public Utility Commissions (PUC). Municipal Utilities and Rural Electric Cooperatives may be unregulated though.
Berwick is an unincorporated community in Polk County, Iowa, United States, on the east bank of Fourmile Creek. It is part of the Des Moines–West Des Moines Metropolitan Statistical Area. In the early 20th century, Berwick and Norwoodville, a mile southwest, were home to several coal mines. The Norwood-White shaft No. 1 (also known as the Klondike No. 1) was 215 feet deep, accessing a 4-foot thick coal seam. By 1908, this mine extended over roughly 200 acres. Norwood-White shaft No. 2 was half a mile to the east. This mine was newer, covering over 40 acres in 1908. The Delaware Coal Company had a shaft a mile northwest of Berwick, with a shaft 170 feet deep. By 1908, this mine covered less than 15 acres. In 1914, Norwood-White produced over 100,000 tons of coal, ranking among the top 24 coal producers in the state.
