Monongahela Incline

As a practical conveyance during the horse-and-buggy era, the Monongahela Incline was one of seventeen built and operated in Pittsburgh in the last century. Of the seventeen, the Monongahela and the Duquesne are the only two remaining operating units. While the Mt. Washington Incline was known as a coal-carrying incline plane in 1854, the Monongahela Incline is probably the earliest passenger-carrying incline in the United States and has been in continuous successful service since its construction.

Known as "the highest and lowest holing in history," the tunnel bored through the Rockies at an elevation of 9,200 feet, 2,800 feet below the surface. Eight hundred men worked around the clock for 3 1/2 years, moving 3 billion pounds of rock.

When Ford Motor Company introduced its new Model T on October 1, 1908, even an inveterate optimist like Henry Ford (1863-1947) could not predict the vast changes that his rather homely new vehicle would produce. What flowed from this series of bold innovations was more than an endless stream of Model Ts — it was the very foundation of the twentieth century itself. The assembly line became the century's characteristic production mode, eventually applied to everything from phonographs to hamburgers.

Minot's Ledge Lighthouse

Minot's Ledge is a wave-swept rock formation in a rocky area of ocean about a mile off the Cohasset shore near Boston. Numerous serious shipwrecks prompted the government to erect a beacon there, and construction began in the summer of 1847.  

The light, constructed on tall iron legs, was put into operation on January 1, 1850. Designers believed that the water would flow freely through the legs, leaving the lighthouse intact. But a terrible winter storm toppled it in 1851, killing the two assistant keepers.

Milwaukee Metropolitan Sewage Treatment Plant

This was America's first large-scale activated sludge plant. The successful operation of Milwaukee's sewage treatment plant led the way for many other American municipalities to adopt its methods of efficient environmental recycling.

Prior to 1925, sewage and industrial waste from the City of Milwaukee and its suburbs (then population 500,000) was discharged to the Milwaukee, Menomonee, and Kinnickinnic rivers, which converge in Milwaukee and flow together through a single outlet into Lake Michigan.

Allis Company

This pump, designed by Edwin Reynolds (1831-1909) and built by the Edward P. Allis company, is the major component of one of the earliest water-pollution control systems. It was capable of pumping more than a half billion gallons of water a day, the highest-capacity pump in the world when installed. It still is used during the summer to pump water from Lake Michigan into the Milwaukee River upstream of the downtown area. This maintains a current in the lower portion of the river and greatly reduces the concentration of pollutants.

Old Mill in Nantucket
Society: ASMEMain Category: MechanicalSub Category: Wind Power ProductionEra: 1700-1749DateCreated: 174650 Prospect StreetNantucketState: MACountry: USAWebsite: http://www.asme.org/about-asme/history/landmarks/topics-m-z/wind-power-production/-165-old-mill-in-nantucket-%281746%29Creator: Wilbur, Nathan

The Old Mill, a smock type of windmill, believed to be the oldest operating windmill in the United States. Most of its parts are original. This mill is the sole survivor of four that once stood along the range of hills west of the town of Nantucket. The long spar and wheel rotate the top of the mill and turn the sails into the wind. Inside, visitors can watch the gears as corn is ground into meal, producing about 5 bushels an hour. Documentation of the restoration of the windmill is located at the Nantucket Historical Association's Research Center.

In 1794, Congress authorized and President Thomas Jefferson signed into law the raising of a Corps of Artillerists and Engineers (now the United States Army Corps of Engineers) to be educated and stationed at the newly created United States Military Academy. The U.S. Military Academy was the first school of engineering in America to offer formal instruction in civil engineering.

Middlesex Canal

While the Erie Canal  has become well-known in the annals of American history, the Middlesex Canal, built two decades earlier and a model for canal engineers throughout young America, has only recently become recognized for its important achievements. Extending 27 miles northeast from Boston harbor to the Merrimack River near present-day Lowell, Masachusetts, the Middlesex Canal provided low-cost and efficient freight transport for almost five decades, helping to establish the canal in the U.S. as a viable means of economic development.

The city of Shreveport could not justify the cost of building a water distribution system solely for the purpose of supplying potable water. It was a series of disastrous fires in the 1880s that galvanized support for a pumping facility that would provide ample water for firefighting.
