Sudbury Aqueduct Linear District
The Sudbury Aqueduct is an aqueduct in Massachusetts. It runs for from Farm Pond at Waverly Street in Framingham to Chestnut Hill Reservoir in Boston’s Chestnut Hill neighborhood. A later built extension main runs from the Farm Pond gatehouse to the gatehouse at the Stearns Reservoir (Framingham Reservoir #1) where additional mains connect to the Brackett and Foss Reservoirs (Framingham #2 and #3.) Going east from Framingham, it runs through Sherborn before entering Natick. From Natick it runs east through Wellesley and Needham to the Charles River, which it crosses on the Echo Bridge into Newton. It ends at the Chestnut Hill Reservoir on the Newton side of the Newton-Boston line. The Massachusetts Water Resources Authority (MWRA) operates the aqueduct. Construction The Sudbury Aqueduct was constructed between 1875 and 1878, and was in use for almost 100 years. It was designed to carry water from the watershed of the Sudbury River to Boston and its surrounding communit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Charles River
The Charles River ( Massachusett: ''Quinobequin)'' (sometimes called the River Charles or simply the Charles) is an river in eastern Massachusetts. It flows northeast from Hopkinton to Boston along a highly meandering route, that doubles back on itself several times and travels through 23 cities and towns before reaching the Atlantic Ocean. The indigenous Massachusett named it ''Quinobequin'', meaning "meandering". Hydrography The Charles River is fed by approximately 80 streams and several major aquifers as it flows , starting at Teresa Road just north of Echo Lake () in Hopkinton, passing through 23 cities and towns in eastern Massachusetts before emptying into Boston Harbor Boston Harbor is a natural harbor and estuary of Massachusetts Bay, and is located adjacent to the city of Boston, Massachusetts. It is home to the Port of Boston, a major shipping facility in the northeastern United States. History .... Thirty-three lakes and ponds and 35 munic ...

Sudbury River
The Sudbury River is a tributary of the Concord River in Middlesex County, Massachusetts, in the United States.U.S. Geological Survey. National Hydrography Dataset high-resolution flowline dataThe National Map accessed October 3, 2011 Originating in the Cedar Swamp in Westborough, Massachusetts, near the boundary with Hopkinton, the Sudbury River meanders generally northeast, through Fairhaven Bay, and to its confluence with the Assabet River at Egg Rock in Concord, Massachusetts, to form the Concord River. It has a drainage area. A 1775 map identifies the river by this name as passing through the town of Sudbury, itself established 1639. On April 9, 1999, nearly of the river were "recognized for their outstanding ecology, history, scenery, recreation values, and place in American literature," by being designated as a part of the National Wild and Scenic Rivers System. The segment of the Sudbury River beginning at the Danforth Street Bridge in the town of Framingham, downs ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Weston, Massachusetts
Weston is a town in Middlesex County, Massachusetts, Middlesex County, Massachusetts, about 15 miles west of Boston. At the time of the 2020 United States Census, the population of Weston was 11,851. Weston was incorporated in 1713, and protection of the town's historic resources is driven by the Weston Historical Commission and Weston Historical Society. The town has one Local Historic District, 10 National Register Districts, 26 Historic Areas, and seven houses individually listed on the National Register of Historic Places. Weston's predominance as a residential community is reflected in its population density, which is among the lowest of Boston's suburbs near or within Massachusetts Route 128, Route 128.

MetroWest Water Supply Tunnel
The MetroWest Water Supply Tunnel (MWWST) is an advanced underground aqueduct that supplies potable water to residents of much of Greater Boston. It is part of the Massachusetts Water Resources Authority (MWRA) water supply system, having entered operation in November 2003. This aqueduct starts at the John J. Carroll Water Treatment Plant in Marlborough, Massachusetts, and ends at an MWRA terminal in Weston, Massachusetts. It is about long (28.3 km) and is constructed far below ground level, mostly in bedrock. It includes several vertical risers called shafts, lined with steel, used to make connections throughout the system. It is built underneath portions of Marlborough, Southborough, Framingham, Wayland, and Weston, Massachusetts, with a wye intersection 235 feet (71.6 m) below the Massachusetts Turnpike former toll booths at State Route 128. History In 1989, the Massachusetts Water Resources Authority (MWRA) issued a planning and design contract for a second transmiss ...

Hultman Aqueduct
The Hultman Aqueduct forms part of the water supply system of eastern Massachusetts, managed by the Massachusetts Water Resources Authority (MWRA). The aqueduct extends from Southborough to Weston, connecting the Cosgrove Tunnel to the distribution network in the Greater Boston area. Opened in 1939, it replaced the Weston Aqueduct. It is now itself a secondary system, having been supplanted as the primary conduit in 2003 by the MetroWest Water Supply Tunnel. From 2009 to 2014, it was rehabilitated and taken offline, in order to repair leaks which were causing losses of at least of water per day in the 1990s. The aqueduct is a pressurized pipe system, consisting of of steel-reinforced pipe at its western end, of bored tunnel under the Sudbury Reservoir, and of steel-reinforced concrete pipe to the Norumbega Reservoir, which acts as a pressure regulation facility. Its western end is an intake, with semicircular diversion dam, on the open channel of the Wachusett Aqueduct in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Weston Aqueduct
The Weston Aqueduct is an aqueduct operated by the Massachusetts Water Resources Authority (MWRA). Now part of the MWRA backup systems, it was designed to deliver water from the Sudbury Reservoir in Framingham to the Weston Reservoir in Weston. The aqueduct begins at the Sudbury Dam, and passes through the towns of Southborough, Framingham, Wayland, and Weston. In 1990, the route, buildings and bridges of the aqueduct were added to the National Register of Historic Places as the Weston Aqueduct Linear District. History The Weston Aqueduct was built early in the 20th century during the third phase of the evolution of the Greater Boston water supply system, now administered by the Massachusetts Water Resources Authority (MWRA). During this phase, the other major elements of the water supply included the Sudbury Dam and Reservoir, and the Wachusett Aqueduct and Reservoir. The purpose of the aqueduct and Weston Reservoir were to channel water to the suburbs north of Boston vi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Elm Bank Reservation
The Gardens at Elm Bank, home of Massachusetts Horticultural Society, occupies of Elm Bank Reservation, a recreational area of woodlands, fields, and former estate property on the Charles River managed by the Massachusetts Department of Conservation and Recreation. The estate's entrance is located at 900 Washington Street ( Route 16), Wellesley, Massachusetts, United States, with the major portion of the grounds located in the neighboring town of Dover. In 1987, the entire site was added to the National Register of Historic Places as Elm Bank. History Property records date back to 1732 when Thomas Fuller owned the tract on land then known as the Natick Plain. The property earned the sobriquet Elm Bank after Colonel John Jones acquired the land in 1740 and planted elm trees along the riverside. After being occupied by families named Loring, Broad, and Otis, the property was sold for $10,000 in 1874 to Benjamin Pierce Cheney, a founder of a delivery company that became American E ...

Cut (earthmoving)
In civil engineering, a cut or cutting is where soil or rock from a relative rise along a route is removed. The term is also used in river management to speed a waterway's flow by short-cutting a meander. Cuts are typically used in road, rail, and canal construction to reduce the length and grade of a route. Cut and fill construction uses the spoils from cuts to fill in defiles to cost-effectively create relatively straight routes at steady grades. Cuts are used as alternatives to indirect routes, embankments, or viaducts. They also have the advantage of comparatively lower noise pollution than elevated or at-grade solutions. History The term ''cutting'' appears in the 19th century literature to designate rock cuts developed to moderate grades of railway lines. ''Railway Age's Comprehensive Railroad Dictionary'' defines a cut as "a passage cut for the roadway through an obstacle of rock or dirt." Creation Cuts can be created by multiple passes of a shovel, grader, scrap ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Embankment (transportation)
A road, railway line, or canal is normally raised onto an embankment made of compacted soil (typically clay or rock-based) to avoid a change in level required by the terrain, the alternatives being either to have an unacceptable change in level or detour to follow a contour. A cutting is used for the same purpose where the land is originally higher than required. Materials Embankments are often constructed using material obtained from a cutting. Embankments need to be constructed using non-aerated and waterproofed, compacted (or entirely non-porous) material to provide adequate support to the formation and a long-term level surface with stability. An example material for road embankment building is sand-bentonite mixture often used as a protective to protect underground utility cables and pipelines. Intersection of embankments To intersect an embankment without a high flyover, a series of tunnels can consist of a section of high tensile strength viaduct (typically built of ...

Siphon
A siphon (from grc, σίφων, síphōn, "pipe, tube", also spelled nonetymologically syphon) is any of a wide variety of devices that involve the flow of liquids through tubes. In a narrower sense, the word refers particularly to a tube in an inverted "U" shape, which causes a liquid to flow upward, above the surface of a reservoir, with no pump, but powered by the fall of the liquid as it flows down the tube under the pull of gravity, then discharging at a level lower than the surface of the reservoir from which it came. There are two leading theories about how siphons cause liquid to flow uphill, against gravity, without being pumped, and powered only by gravity. The traditional theory for centuries was that gravity pulling the liquid down on the exit side of the siphon resulted in reduced pressure at the top of the siphon. Then atmospheric pressure was able to push the liquid from the upper reservoir, up into the reduced pressure at the top of the siphon, like in a baromet ...

Weir
A weir or low head dam is a barrier across the width of a river that alters the flow characteristics of water and usually results in a change in the height of the river level. Weirs are also used to control the flow of water for outlets of lakes, ponds, and reservoirs. There are many weir designs, but commonly water flows freely over the top of the weir crest before cascading down to a lower level. Etymology There is no single definition as to what constitutes a weir and one English dictionary simply defines a weir as a small dam, likely originating from Middle English ''were'', Old English ''wer'', derivative of root of ''werian,'' meaning "to defend, dam". Function Commonly, weirs are used to prevent flooding, measure water discharge, and help render rivers more navigable by boat. In some locations, the terms dam and weir are synonymous, but normally there is a clear distinction made between the structures. Usually, a dam is designed specifically to impound water behind ...

Sudbury Reservoir
The Sudbury Reservoir (2.02 square miles) is an emergency backup Boston metropolitan water reservoir in Massachusetts, located predominantly in Southborough and Marlborough, with small sections in Westborough and Framingham. It was created when the Sudbury Dam was constructed to impound the Stony Brook branch of the Sudbury River; no part of the reservoir lies in the town of Sudbury. Nearly in the Sudbury Reservoir watershed are administered by the Massachusetts Department of Conservation and Recreation as a limited-access public recreation area. History The reservoir was first begun in 1878, as part of a system of reservoirs fed from the Sudbury River to supplement the Lake Cochituate system in Natick. Today's reservoir was created by excavation from 1894 to 1898, with construction undertaken in sections. It was begun by the City of Boston but completed by the newly formed Metropolitan Water Board (predecessor to the modern Massachusetts Water Resources Authority). All told, ...
