Georgetown Reservoir
The Georgetown Reservoir is a reservoir that provides water to the Washington, D.C., District of Columbia. Part of the city’s water supply and water purification, treatment infrastructure, it is located in the The Palisades, Washington, D.C., Palisades neighborhood, approximately two miles downstream from the Maryland–D.C. boundary. The reservoir was built by the United States Army Corps of Engineers as part of the Washington Aqueduct project. It was partially completed by 1858, but work was suspended for lack of funds. Construction began again in 1862, and was complete in 1864. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Castle Gatehouse, Washington Aqueduct
Castle Gatehouse, Washington Aqueduct is a pumping station at the Georgetown Reservoir on the Washington Aqueduct in The Palisades, Washington, D.C., The Palisades neighborhood of Washington, D.C., United States. 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 United States Army Corps of Engineers, Army Corps of Engineers to construct a water supply for the city of Washington, using the Potomac River at Great Falls (Potomac River), 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 (Potomac River), Little Falls Branch was used as an interim source until the pipeline was completed in 1864. The water was routed to Dalecarlia Reservoir, followed by Georgetown Reservoir. Improvements to the water system in the late 19th century included the Castle Ga ...

Dalecarlia Reservoir
Dalecarlia Reservoir is the primary storage basin for drinking water in Washington, D.C., fed by an underground aqueduct in turn fed by low dams which divert portions of the Potomac River near Great Falls and Little Falls. The reservoir is located between Spring Valley and the Palisades, two neighborhoods in Northwest Washington, and Brookmont, a neighborhood in Montgomery County, Maryland. The reservoir was completed in 1858 by the United States Army Corps of Engineers as part of the Washington Aqueduct project. It began providing water on January 3, 1859. Initially the reservoir provided water to the city from the adjacent Little Falls Branch until the aqueduct construction was completed. Regular water service from the Potomac River source through the aqueduct commenced in 1864. The reservoir was modified in 1895 and 1935 to improve water quality and increase water supply. In 1942, the headquarters of the Army Map Service was established on the grounds adjacent to the r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chesapeake Bay Watershed
The Chesapeake Bay ( ) is the largest estuary in the United States. The Bay is located in the Mid-Atlantic region and is primarily separated from the Atlantic Ocean by the Delmarva Peninsula (including the parts: the Eastern Shore of Maryland / Eastern Shore of Virginia and the state of Delaware) with its mouth of the Bay at the south end located between Cape Henry and Cape Charles. With its northern portion in Maryland and the southern part in Virginia, the Chesapeake Bay is a very important feature for the ecology and economy of those two states, as well as others surrounding within its watershed. More than 150 major rivers and streams flow into the Bay's drainage basin, which covers parts of six states (New York, Pennsylvania, Delaware, Maryland, Virginia and West Virginia) and all of District of Columbia. The Bay is approximately long from its northern headwaters in the Susquehanna River to its outlet in the Atlantic Ocean. It is wide at its narrowest (between Kent County ...

Reservoirs In Washington, D
A reservoir (; from French ''réservoir'' ) is an enlarged lake behind a dam. Such a dam may be either artificial, built to store fresh water or it may be a natural formation. Reservoirs can be created in a number of ways, including controlling a watercourse that drains an existing body of water, interrupting a watercourse to form an embayment within it, through excavation, or building any number of retaining walls or levees. In other contexts, "reservoirs" may refer to storage spaces for various fluids; they may hold liquids or gasses, including hydrocarbons. ''Tank reservoirs'' store these in ground-level, elevated, or buried tanks. Tank reservoirs for water are also called cisterns. Most underground reservoirs are used to store liquids, principally either water or petroleum. Types Dammed valleys Dammed reservoirs are artificial lakes created and controlled by a dam constructed across a valley, and rely on the natural topography to provide most of the basin of the re ...

Sluice
Sluice ( ) is a word for a channel controlled at its head by a movable gate which is called a sluice gate. A sluice gate is traditionally a wood or metal barrier sliding in grooves that are set in the sides of the waterway and can be considered as a bottom opening in a wall. Sluice gates are one of the most common hydraulic structures in controlling flow rate and water level in open channels such as rivers and canals. They also could be used to measure the flow. A water channel containing a sluice gate forms a type of lock to manage the water flow and water level. It can also be an open channel which processes material, such as a River Sluice used in gold prospecting or fossicking. A mill race, leet, flume, penstock or lade is a sluice channeling water toward a water mill. The terms sluice, sluice gate, knife gate, and slide gate are used interchangeably in the water and wastewater control industry. They are also used in wastewater treatment plants and to recover minerals in minin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
District Of Columbia Water And Sewer Authority
The District of Columbia Water and Sewer Authority (DC Water) provides drinking water, sewage collection and sewage treatment for the District of Columbia, in the United States. The utility also provides wholesale wastewater treatment services to several adjoining municipalities in Maryland and Virginia, and maintains more than 9,000 public fire hydrants in the District of Columbia. DC Water was created in 1996 when the District Government and the U.S. federal government established it as an independent authority of the District government. Service area DC Water provides more than 600,000 residents, 16.6 million annual visitors, and 700,000 people employed in the District of Columbia with water, sewage collection, and treatment. The agency also provides wholesale wastewater treatment for 1.6 million people in Montgomery and Prince George's counties in Maryland, and Fairfax and Loudoun counties in Virginia.

Water Supply Network
A water supply network or water supply system is a system of engineered hydrologic and hydraulic components that provide water supply. A water supply system typically includes the following: # A drainage basin (see water purification – sources of drinking water) # A raw water collection point (above or below ground) where the water accumulates, such as a lake, a river, or groundwater from an underground aquifer. Raw water may be transferred using uncovered ground-level aqueducts, covered tunnels, or underground water pipes to water purification facilities. # Water purification facilities. Treated water is transferred using water pipes (usually underground). # Water storage facilities such as reservoirs, water tanks, or water towers. Smaller water systems may store the water in cisterns or pressure vessels. Tall buildings may also need to store water locally in pressure vessels in order for the water to reach the upper floors. # Additional water pressurizing components such ...

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. Initially the system provide ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sedimentation (water Treatment)
Sedimentation is a physical water treatment process using gravity to remove suspension (chemistry), suspended solids from water. Solid particles entrained by the turbulence of moving water may be removed naturally by sedimentation in the still water of lakes and oceans. Settling basins are ponds constructed for the purpose of removing entrained solids by sedimentation. Clarifiers are tanks built with mechanical means for continuous removal of solids being deposited by sedimentation. Clarification does not remove dissolved species. Sedimentation is the act of depositing sediment. Basics Suspended solids (or SS), is the mass of dry solids retained by a water filter, filter of a given porosity related to the volume of the water sample. This includes particles 10 μm and greater. Colloids are particles of a size between 1 nm (0.001 µm) and 1 µm depending on the method of quantification. Because of Brownian motion and electrostatics, electrostatic forces balancing ...
