The building is on the National Register of Historic Places and contributes to the Washington Aqueduct National Historic Landmark. History In 1852 the United States Congress authorized the Army Corps of Engineers to construct a water supply for the city of Washington, using the Potomac River at Great Falls as its source. Construction of a 12-mile pipeline began in 1853, and portions of the system began operation in 1859. Little Falls Branch was used as an interim source until the pipeline was completed in 1864.

McMillan Reservoir
The McMillan Reservoir is a reservoir in Washington, D.C. that supplies the majority of the city's municipal water. It was originally called the Howard University Reservoir or the Washington City Reservoir, and was completed in 1902 by the U.S. Army Corps of Engineers. Construction history The Macmillan Reservoir was built in 1902 on the site of Smith Spring, one of the springs previously used for drinking water. Washington's earliest residents relied on natural springs but this came to be inadequate as the city's population grew. In 1850, Congress determined that the Potomac River should be the city's principal source of water. Washington Aqueduct A congressionally funded engineering study was conducted to determine the most available mode of supplying water to the city. Work and study conducted under the leadership of Lieutenant Montgomery C. Meigs culminated into the development of the Washington Aqueduct which began operations on January 3, 1859.

Water Supply Infrastructure On The National Register Of Historic Places
Water (chemical formula ) is an inorganic, transparent, tasteless, odorless, and nearly colorless chemical substance, which is the main constituent of Earth's hydrosphere and the fluids of all known living organisms (in which it acts as a solvent). It is vital for all known forms of life, despite not providing food, energy or organic micronutrients. Its chemical formula, H2O, indicates that each of its molecules contains one oxygen and two hydrogen atoms, connected by covalent bonds. The hydrogen atoms are attached to the oxygen atom at an angle of 104.45°. "Water" is also the name of the liquid state of H2O at standard temperature and pressure. A number of natural states of water exist. It forms precipitation in the form of rain and aerosols in the form of fog. Clouds consist of suspended droplets of water and ice, its solid state. When finely divided, crystalline ice may precipitate in the form of snow. The gaseous state of water is steam or water vapor. ...

Buildings And Structures On The National Register Of Historic Places In Washington, D
A building, or edifice, is an enclosed structure with a roof and walls standing more or less permanently in one place, such as a house or factory (although there's also portable buildings). Buildings come in a variety of sizes, shapes, and functions, and have been adapted throughout history for a wide number of factors, from building materials available, to weather conditions, land prices, ground conditions, specific uses, prestige, and aesthetic reasons. To better understand the term ''building'' compare the list of nonbuilding structures. Buildings serve several societal needs – primarily as shelter from weather, security, living space, privacy, to store belongings, and to comfortably live and work. A building as a shelter represents a physical division of the human habitat (a place of comfort and safety) and the ''outside'' (a place that at times may be harsh and harmful). Ever since the first cave paintings, buildings have also become objects or canvasses of much artisti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Portland Cement
Portland cement is the most common type of cement in general use around the world as a basic ingredient of concrete, mortar, stucco, and non-specialty grout. It was developed from other types of hydraulic lime in England in the early 19th century by Joseph Aspdin, and is usually made from limestone. It is a fine powder, produced by heating limestone and clay minerals in a kiln to form clinker, grinding the clinker, and adding 2 to 3 percent of gypsum. Several types of portland cement are available. The most common, called ordinary portland cement (OPC), is grey, but white Portland cement is also available. Its name is derived from its resemblance to Portland stone which was quarried on the Isle of Portland in Dorset, England. It was named by Joseph Aspdin who obtained a patent for it in 1824. His son William Aspdin is regarded as the inventor of "modern" portland cement due to his developments in the 1840s. The low cost and widespread availability of the limestone, sh ...
